Version: 4.1.1 2017-09

1 General Instructions 1.1 Standards brief This document defines the standards applying to any videoconference installation undertaken at the University.

Videoconference facilities are usually, but not always, limited to the following types of spaces:

• Teaching spaces • Meeting rooms • Personal offices

Unless otherwise specified in this document, manufacturers’ specifications and installation instructions shall be adhered to otherwise installation practices will follow this standard, provided that these practices do not breach occupational health and safety regulations.

It is the responsibility of the staff member, contractor, consultant or other agent associated with the contractor or consultant to clarify specifications with Deakin eSolutions (DeS) Audio Visual & Networks (AVN) Division before work commences.

1.2 Policy This standard applies to all Videoconference systems throughout Deakin University and associated locations managed by Deakin eSolutions.

1.3 Standard Document Access All Deakin University DeS staff and contracted personnel are provided access to this document. Designers, installers and contractors must ensure they have the most current version of all standards prior to engaging in any work. The most recent version can be found on the internet at: https://blogs.deakin.edu.au/avn-docs/standards-documents/vc-standards/

1.4 Related Documents Many aspects of the system design requirements are specified in other companion documents within Volume 2 in particular 2.2 Audio Visual Technical Design Standards. These documents must be read together to constitute the complete Standard.

1.5 Conflict of Information or Clarification Whenever a conflict of information occurs or clarification of instruction is required all queries shall be made to DeS AV and Network Manager.

1.6 Non-standard configurations All non-standard implementations must be approved in writing by the DeS AV and Network Manager strictly on a case-by-case basis.



Version: 4.1.1 2017-09

1.7 Roles and Responsibilities The following roles are referenced in this and related standards. Role Responsibility DeS AV and Network Manager Holds responsibility for all audiovisual and network

standards and their adherence, provision, maintenance and security of all audiovisual and network infrastructure. All Engineers ultimately report to this role.

DeS Senior Engineer (AV/Networks)

A staff member with significant technical experience whose role is to provide architectural design and quality control of audiovisual and network fitouts.

DeS Engineer (AV/Networks)

A staff member with technical experience whose role is to audit, provision and maintain audiovisual and network infrastructure.

Project Manager (DeS) Responsible for ensuring DeS-supplied deliverables agreed to by formal project board are delivered on time, to budget and within agreed quality parameters while managing project communication, dependencies and reporting. Defects with an audiovisual or network fitout will be reported to the Project Manager (DeS) by DeS Communications Engineer (AV/Networks).

Project Manager (FSD) Responsible for ensuring FSD-supplied

deliverables agreed to by formal project board are delivered on time, to budget and within agreed quality parameters while managing project communication, dependencies and reporting. Defects with an audiovisual or network fitout for which FSD have project management responsibility will be reported by the Project Manager (FSD).

External supplier A company such as a third party audiovisual or integration vendor, or network cabling provider, contracted by Deakin University to provide specified products and/or services.

Subcontractor A company or other agent hired by an external supplier to provide all or some products or services required to fulfil a contract the external supplier holds with Deakin University.


Deakin eSolutions of 63 Version: 4.1.1 2017-09

2 Installation standards and conditions This document does not replace, supersede or override formal contractual terms and conditions between the parties. This section draws suppliers’ attention to some important requirements.

2.1 Variation agreements Any deviation from the Standard specification must be agreed to in writing by DeS AV and Network Manager prior to commencement of any work.

Any building features such as:

• Plaster • Ceiling tiles • Carpet tiles

that are altered during the installation process must be restored to original condition, to the satisfaction of the site supervisor.

2.2 DeS site inspections The contractor shall agree to regular site visits from DeS project representatives and have in place a means of communication and escalation between senior technical staff within both organizations prior to commencement of work.

2.3 Contractor to fully self-inform The contractor shall fully self-inform and not rely on representations.

2.4 Fit-for-purpose Solutions shall be fit-for-purpose.

2.5 Commissioning procedures

2.5.1 Video codec Video codecs shall be commissioned according to the required DeS AVN process as per AV Standards 2.2.

2.5.2 Radio microphones Radio Microphone planning and implementation for video conference spaces will be per ICT 2.1 Audio Visual Standards.



3 Purchasing requirements 3.1 Standard manufacturer and model range Deakin has standardised on Cisco Video Conference endpoints. No other brand or configuration options of videoconferencing equipment shall be deployed. Appropriate models will be specified in Tender and/or Scope Documentation.

Any company undertaking videoconferencing works for Deakin must be an accredited Cisco Platinum Partner. We have standardised firmware versions and configuration settings which need to be adhered to. Audio Visual & Networks will pre-configure all units prior to installation/integration in-room.

3.2 Maintenance contract Three years’ full maintenance support with the DeS selected vendor partner must be purchased at the time the unit is purchased.

Maintenance Type: Cisco SmartNet Maintenance ECDN 8x5xNBD & SW Updates Maintenance Term: 3 Years (36 Months)

Special discounted bundle pricing negotiated for supply to Deakin only applies when the correct bundle of options, as set out in section 3.3, is selected, including 3 years full maintenance support. A unit will not be installed or supported by DeS if it is not under an initial 3-year maintenance contract. The maintenance for the hardware must be aligned to start coinciding with the installation date and not prior.

3.3 Standard options All videoconference units shall be purchased with the following options configured. Special discounted bundle pricing negotiated for supply to Deakin only applies when the correct bundle of options as set out below is selected, including 3 years full maintenance support.

• 3 years maintenance included at time of purchase (refer section 3.2) • Remote Monitoring Option • Do NOT Purchase Multisite Option • All Standard Inclusions as per Manufacturer Parts List



4 Functional requirements

4.1 ‘Telepresence’-grade solutions ‘Immersive telepresence’-grade solutions are encouraged. The Deakin Standards recognize that the key attributes of immersive telepresence-grade videoconference facilities are:

• CiscoTrackingCamerastodelivertightlyframedlife-sizeimages

• Roomacoustictreatmentandaudiosystemstodeliverqualitysound

• Roomlighting,colours,interiordecorationtreatmentandvideosystemstodeliveruniform,standardized,highqualityimages

• Easeofuseintuitive,simple,userinterfaces,includingsimpledialling

• SeamlessglobalreachITUStandardsdualstream(dualdisplayformat)compliantsystems(thevalueofatelecommunicationsenvironmentgrowswiththesquareofthenumberofreachableparties–Metcalfe’sLaw).

i.e. ‘Telepresence’ is a package that delivers a standards-compliant ‘life-like’ experience like being in the same room.

4.1.1 Implementation For personal offices (AV2) Skype for Business is the preferred Video Conference Endpoint. Cisco Spark Room Kit may be deployed to cater for more than 3 participants in a small space/personal office, with prior approval by DeS AV and Network Manager.

For personal videoconference solutions (Skype for Business), this means use by a single person only.

For meeting rooms (AV4) this means wide-format tables (arc, V, trapezoidal, oval, half oval), with camera pre-sets configured for each pair of seats (2-shots).



Illustrative case study: A typical 6 m x 4 m meeting room (F-ad6.202) was originally configured as a 9 seat long rectangular style meeting room as shown in figure (a) below.

Reconfigured for telepresence-grade use, a wide arc (or wide V) table can accommodate 6 to 8 seats (figure b) while a wide rectangular table can accommodate 8 to 10 (figures c and d).

(A) LONG RECTANGLE (B) WIDE ARC/V (C) WIDE RECTANGLE (D) WIDEST RECTANGLE

Configured for a long rectangular table it suffers from all the usual limitations of that format (figure (A)):

5.2.2.1 Implementation The Cisco Spark Room Kit is the default standard unit and is ideal for small-to-medium size videoconference meeting rooms in both single and dual screen configurations (AV4-xA), on the condition that the inbuilt microphone or 1-2 external microphones provide sufficient coverage.

The Cisco Spark Room Kit Plus is the standard for medium size videoconference meeting rooms in both single and dual screen configurations (AV4-xA), on the condition that 2-3 external microphones provide sufficient coverage.

In larger meeting rooms where additional inputs are required the SX80 is substituted (AV4-xB), as set out below:

3c (YC/C) n/c – not used

Notes: [1], [2], [3]: As above – refer notes to table on preceding page.



[4]: Inputs 2h and 2d are available as general-purpose but rarely used auxiliary inputs; Doc Cam is non-standard in AV4; to use both 2h and 2d in the same system requires AMX control (otherwise choice is only available by administrator configuration and only one is available via system-integral UI controller)

[5]: As below – refer following sections:

Note [5]: AMX control The use of an AMX in a meeting room is to be avoided where possible, the system integral remote controller being a more attractive choice.

AMX is non-standard for AV4 and as for any other non-standard configuration, approval must be obtained from the DeS AV and Network Manager on a case-by-case basis.

Where needed, an auto-switching video switch shall be supplied to select between PC and laptop input/s. Manual control adds unnecessary complexity to the user function and is not provided. An AMX controller or touch panel is therefore not required for this function. The auto-switcher priority shall be:

1. Laptopattheprimarysittingposition(facingtowardsthescreens)2. 2ndlaptop(ifprovisioned)atthepresenter’sposition(facingtowardsthelocalaudience)3. SystemPC

LCD panels shall be configured to automatically go into Standby Mode when no video sync is detected from the videoconference unit, and to automatically wake when video sync is detected from the videoconference unit. Therefore an AMX is not required for LCD power-management.

AMX controller is required to control projectors (which cannot automatically power on/off upon detection of video sync), and may also be required for other secondary functions such as blinds or lights, however an AMX touch-screen is still to be avoided – the AMX controller can sense required operation by combination of control signalling received from the codec and other attached devices, plus PIR inputs. On receiving an incoming call, or other local activation of the codec (e.g. for local display of PC content), the AMX controller must automatically activate the projectors. Following session end the AMX controller must automatically shut-down the projectors.

A special case is hybrid spaces that are used for both meetings and teaching – all teaching spaces require an AMX touch panel. Hence such hybrid spaces are based on the AV6 configuration (below).



5.2.3 AV6-V – Teaching Space Videoconferencing is optional in an AV6 teaching space.

• AsinglefullyconfiguredbasedesigncoversallAV6,AV7andAV8,includinghybrid(AV4/6-H)applications

• Fullintegrationsolutions,completewithAMXcontrollerandAMXtouch-screen,aremandatoryforAV6,AV7andAV8,includinghybrid(AV4/6-H)applications

• DualdisplayismandatoryforallAV6,AV7andAV8,includingvariant(AV4/6-HandAV6-C)applications

5.2.3.1 Implementation Where a teaching space requires videoconferencing, a Cisco SX80 is provisioned. The codec is installed in the equipment rack along with the other system AV equipment – this may be within the presenter’s desk in the room, or remotely in an AV rack nearby but outside the room. The system is always controlled via AMX.

Dual displays are always provisioned. For small classrooms, this may be dual LCDs, but generally dual projectors will be provisioned. The presenter’s desk is provisioned with 3 displays: 2 vision monitors and 1 AMX touch screen. The vision feeds to the desk are independent from the vision to the main displays. Specific vision routing is programmed specific to the teleteaching application (refer section 4.6 for details).

Two cameras are provisioned, one at the rear of the space pointing towards the presenter, and one at the centre of the front of the space facing towards the audience, located between the two displays.

Document Camera, system PC and provision to connect a laptop are always provided.

5.2.4 AV8 – Lecture Theatre with videoconferencing Videoconferencing is optional in a lecture theatre. AV8 specifies the requirements of a lecture theatre with video conferencing.

5.2.4.1 Implementation Where a lecture theatre requires videoconferencing, a Cisco SX80 is provisioned. The codec is installed in the equipment rack along with the other system AV equipment – this may be within the presenter’s desk in the room, or remotely in an AV rack nearby but outside the room. The system is always controlled via AMX.

Dual displays are always provisioned. Suitable dual projectors shall be provisioned. The presenter’s desk is provisioned with 3 displays: 2 vision monitors and 1 AMX touch screen. The vision feeds to the desk are independent from the vision to the main displays. Specific vision routing is programmed specific to the teleteaching application (refer section 4.6 for details).

At least two cameras are provisioned, one at the rear of the space pointing towards the presenter, and one at the centre of the front of the space facing towards the audience. Additional cameras are provisioned as appropriate.

Document Camera, system PC and provision to connect a laptop are always provided.

5.3.1 AV4/6-H – Hybrid videoconference meeting/seminar/teaching space Some videoconference meeting rooms may also be used for small-group tutorials, seminars or informal teaching. These are always flat-floored spaces. Technical design uses the AV6-V ‘base’ detailed design, using the SX80, but cut-back for the intended application. As such, the room shall be fitted with dual displays, system PC, an AMX controller and touch-screen.

The vision flow settings shall default to those suitable for a normal AV4 ‘meeting’, however for larger hybrid AV4/6-H spaces a welcome screen may be provided to select between start-up vision settings suitable for AV4 (‘meeting’) and AV6 (‘teaching’) sessions. However, these options affect only the initial settings, and do not limit functionality during the session – the full AV4 and AV6 functionality is available during the session.

A presenter station is optional (generally omitted), but as a minimum the 2nd Laptop connection point must be provided for a presenter near the front of the room. The AMX touch screen cable must be long enough to allow the touch screen to be used in primary meeting seats and in



presenter seats near the front. The AMX menu layout shall be opposite to the standard AV6, i.e. in hybrid spaces: Left display choices are on the Left of the touch screen, and Right display choices are on the Right of the touch screen.

Where flexible furniture is required, suitable microphone arrangements must be approved by the DeS AV and Network Manager on a case-by-case basis, and according to the requirements of section 6.8 below.

Alternatively, a standard dual display AV4 design can be successfully used ‘as is’ for low-end small-group hybrid meeting/seminar/teleteaching applications.

5.3.2 AV9 – Teleteaching collaboration space (e.g. Deakin Learning Centre spaces)

Same as basic AV6-V teleteaching classroom, except with the following additions: • Push-to-talkmicrophonesystemoneachstudentdesk• CamerafollowsactivemicautomaticPTZcameracontrolsystem



6 Standard Models There are three distinct categories of videoconference unit:

Type Deakin standard model Supersedes Desktop appliance Skype For Business EX90 Component system (non-integrated) Spark Room Kit/Plus C20 Plus/SX20 SX80 C60/C90 Integrated system (AMX integration) SX80 C60 C90

The superseded or any other models are not to be provisioned or installed under any circumstances.

6.1 Firmware Due to firmware compatibility issues that exist between videoconferencing infrastructure and endpoints, DeS sets a firmware baseline which is upgraded approximately every 6~12 months. All equipment being introduced into the videoconferencing environment will adhere to the baseline.

6.2 Displays For current model specifications refer to the scope of works. Displays must be tested and approved by Deakin Audio Visual & Network Unit.

In dual-screen deployments: • BothdisplaysshallALWAYSbeofthesametypeandsize• TheRightscreen(asviewedfromtheaudience)shallbethe(2nd)‘content’display• TheLeftscreen(asviewedfromtheaudience)shallbethe(primary)far-end’livevideo’display

6.3 Speakers The speakers will be supplied in a colour that matches the monitor for uniformity of installation. For example, black matte monitor will have black matte speakers.

For dual screen installations, one pair of speakers only will be deployed (i.e. not four speakers for two monitors).

In rooms with separated Program Audio and Voice Reinforced Audio, the Far End audio shall be sent to the (Front-of-House) Program Audio speakers only, to achieve correct spatial alignment of the Far End audio with the Far End video displays.

All speakers will be installed as per the ICT-AV Standards 2.2. Specific models will be outlined in the scope of works, and all models must have prior testing and approval by Deakin eSolutions Audio Visual & Networks Unit.



6.4 Microphones The audit of the installation space will determine the type and number of microphones required.

All microphones shall be fixed to the table in the correct orientations as designed by the room audit. The ‘backs’ of all directional microphones are to face towards the videoconference display screens, exact orientation as specified by the detailed room design.

Wireless handheld microphones and wireless lapel microphones are only to be provisioned in classrooms and lecture theatres (AV6/AV8/AV9) – refer ICT 2.2 AV Technical Design Standards for details.

All microphones will be installed as per the ICT-AV Standards 2.2. Specific models will be outlined in the scope of works, and all models must have prior testing and approval by Deakin eSolutions Audio Visual & Networks Unit.

6.4.1 Microphone placement Microphones shall be fixed into their correct positions (not user alterable), and face generally away from the FoH presentation area.

Microphones shall be placed at least 0.5 m from side or rear table edges (preferably greater than 0.6 m).

Microphones shall be provisioned at the rate of approximately 1 microphone per: • 7seatsfortypicalrectangulartable• 4seatsforlargersquareor‘U’-shapedtable• smallround/oval/squaretable(3to6seats)

6.4.2 Reconfigurable spaces Fixed configuration rooms (i.e. fixed furniture layout) are strongly recommended so that quality for-purpose microphone arrangements can be provisioned. Flexible use rooms (movable furniture) suffer from degraded audio because of the difficulty of adequately provisioning microphone coverage.

Wireless microphones are not to be used to address this application. Advanced ceiling microphone arrays are suitable for this application as per ICT-AV Standard 2.2.

Reconfigurable spaces must have suitable acoustic treatment to exceed the requirements set out in section 11.6.



6.5 Cameras Only Cisco Precision HD (PHD) cameras shall be used, where an internal camera is not available.

The number of cameras to be installed in a videoconference space will be determined at audit, however the below table serves as a guide:

Type of space Standard camera arrangement Small Meeting room

Teaching space or Lecture Theatre

(AV6-V/C, AV8 inc. hybrid AV4/6-H spaces)

SX80 with multiple cameras Teaching spaces will have at least two cameras. One will be positioned at the rear of the venue directed toward the presenter. The second camera will be mounted in the centre front wall (between dual projected images) directed toward the audience.



6.5.1 Camera pre-sets Camera pre-sets depend on the layout and purpose of the room. The following table is to be used when setting camera pre-sets. Each pre-set records Pan, Tilt, Zoom and Focus settings along with Mic Mute status at the time of programming. Therefore, pre-sets are always to be programmed with Mic Mute OFF.

Type of space Standard camera arrangement

that projector lenses also in shot for DeS troubleshooting purposes)

Pre-set 6 – CAM 2 – Wide shot of lecturer, covers the projected images too (for far-end monitoring/checking)

Deakin Learning Centre type spaces with push-to-talk student microphones shall in addition have one Audience Cam (CAM 1) pre-set for each push-to-talk station. Pressing the push-to-talk button will activate the associated pre-set.

NOTE: Teaching Spaces and Lecture theatres will default to Camera 1 Pre-set 1.

6.5.2 Camera cabling Where a cable run is 10 metres or less, approved HDMI “High Speed” (Category 2) Standard cables shall be used, directly end-to-end. Where a cable run is over 10 metres HDMI will be used over CAT6a, using approved transceivers as specified in ICT-AV Standards 2.2.

Where applicable, the Cisco Precision HD camera shall be connected to the codec as per Cisco specifications, including daisy-chained control cable.



Additional cameras (2nd, 3rd, nth camera) require Ethernet network connection to allow for remote software upgrades. Camera must be on the same subnet as the codec.

6.5.3 Use of PC/laptop PC/laptop/tablet/smartphone cameras are used by desktop/mobile videoconference software applications, but are not a component of a hardware-based videoconference system.

6.6 Remote control The Cisco Touch-10 system integral touch panel shall be provided as the standard user interface device for video conference systems that do not have AMX touch controllers in:

• allfixed-furnituremeetingrooms;and

• wherepracticalinflexiblefurniturespaces,inwhichcasetheTouch-10shouldpreferablybeplacedonacredenzaorotherconvenientfixedfurniture.

In all cases, the entirety of the proprietary 7.5 m cable must be freely available so users can move the Touch-8 panel to suitable location.



7 Equipment and component protection 7.1 Mounting of codecs Videoconference units shall not be installed in a roll-about or portable fashion.

Where codecs are free standing, and not placed into a rack, they will be mounted as per manufacturer specifications.

7.2 Power protection and distribution Power distribution and protection for all videoconferencing equipment shall be as specified in ICT 2.2 Audio Visual Technical Design Standards.

7.3 Protection from the elements and tampering All components of the installation shall be adequately protected from vandalism, mechanical damage, and the ingress of moisture, corrosive fumes, dust, high temperature or any other circumstance under normal operating conditions which may expose the system to unreliable performance.



8 Network and supported protocols A dedicated Ethernet network point shall be provisioned for the use of the videoconference unit. A videoconference unit can be plugged into any Ethernet wall outlet.

Videoconference systems cannot operate over 802.11 WiFi wireless network.

For further information, refer ICT Volume 6 – Network Standards.

8.1 Videoconference subnets The network point is automatically configured onto a correct videoconference specific VLAN and subnet.

All IP Address/Network configuration will be performed by DeS Staff prior to installation.



9 Central video communication infrastructure 9.1 Endpoint Registration Endpoints are registered to Deakin on premise Cisco Collaboration infrastructure.

More information:

9.1.1 Multipoint Calls MCU bridging services are provided using on premise Cisco Collaboration infrastructure. Contact the DeS AV and Network Manager for further technical details.

9.1.2 Telephony failover Endpoints which are registered to the Deakin on-premise Cisco Collaboration infrastructure are reachable as audio only endpoints if there is no video component in the call.



10 Configuration 10.1 Cisco Telepresence Management Suite (TMS) All units supported by DeS are to be managed using the Cisco Telepresence Management Suite (TMS). A unit will not be supported if it is not added to TMS.

10.2 Configuration Templates This system specifies several Configuration Templates to be deployed. The appropriate Configuration Template should be deployed to the unit. Configuration Templates are designed so that units across the fleet have consistent settings for interoperability and easy support.

Additional Configuration Templates are used for special purposes such as diagnostics.

All configuration templates will be deployed to the codec by DeS Staff at the conclusion of the installation.

10.3 Auto Answer Configuration

Auto-answer is enabled by default in all teaching spaces and most corporate spaces. Due to privacy and security DeS may elect to disable auto-answer in high-profile spaces and/or off-site spaces to ensure security and privacy of participants in room not utilising the videoconference platform.

10.4 AMX Controlled Rooms Refer to ICT-AV Standards 2.2 for further information on AMX Controlled spaces at Deakin University. AMX Control of codecs shall be strictly via IP. RS-232 Control may be required as outlined in the scope of works.



11 Environment Tighter lighting and interior design requirements apply to all videoconference spaces, as compared with normal office or teaching spaces, particularly due to the demands of the video camera and audio system as regards:

• brightness (in particular avoidance of low lighting levels which result in video noise that overloads the video compression algorithm);

• uniformity of brightness (to avoid hot-spots due to the lower dynamic range of video cameras as compared with the human eye);

• positioning of lighting to avoid shadows on participants’ faces; • positioning of lighting to avoid washing out contrast on displayed images (we spend

significant money on high-contrast / high-brightness display technology, so we must not destroy the effect by flooding the presentation surface (whether projected or LCD) with inappropriately placed lighting)

• colours – in particular of table tops (to correctly in-fill shadows while not overexposing camera) and walls;

• uniform colour temperature for all lighting in the space (no mixture of different types of lights);

• reduced contrast range (i.e. of luminosity) between the various colours in the space; • interior room decoration: needs to strike a balance between not too much fussy detail

while still engendering a normal comfortable meeting room environment, in particular need to avoid fine detail (e.g. fine grid patterns on fabrics, blinds, etc.) that interact badly with the camera). A reasonable compromise can be adding some minor contrasting feature on the side walls (e.g. curtains for sound dampening), or a slightly contrasting wall colour on the sides cf the rear wall;

• background suitable for correct functioning of auto-focus camera, in particular: • fine-detailin-shotbutatadifferentdistancefromthecamerathantheparticipants

• signage to be of adequate size to be easily readable, even in wide-shot (with the progressive growth of external videoconferences it is important to include Deakin branding in all spaces);

• no high gloss surfaces: reflection of lighting or screen images back into camera (in particular rear wall – must avoid whiteboards, glass and other high gloss surfaces);

• no bright direct light into camera lens (even off-axis / out-of-shot); • windows must be avoided, in particular:

• camera hyper-sensitivity to blue light;



• acoustic treatment to minimize echo, reverberation and noise is very important for successful videoconferences – poor sound is the single biggest cause of problems during videoconference sessions.

11.1 Lighting Deakin follow Cisco Best Practices regarding lighting configuration in Video Conference Spaces.

For further information and guidelines on best practice lighting in Video Conference Spaces refer to the Cisco Project Workspace Room Design Guide, available from the Cisco Website:

https://www.cisco.com/web/telepresence/collateral/pr.pdf

11.1.1 Mixed type lighting not to be used Lights of different types (e.g. fluorescent and LED) are not to be incorporated into the same space.

Lights of different colour temperature are not to be incorporated into the same space, unless these are fitted within the one luminaire and mixed within the fitting so as to produce a single broader and/or controllable spectrum, e.g. RGB LED arrays; or Phosphor-LED arrays comprising a mixture of 3000 K and 4000 K LEDs within the one assembly are acceptable.

Neither incandescent nor halogen lighting shall be used. There are no exceptions to this requirement. For example: even spot-lighting for presenters in large lecture theatres (AV8) can be provisioned using LED spotlights of the same colour spectrum as the room lighting.

11.1.2 Fluorescent lighting Fluorescent lighting is an acceptable lighting choice, subject to the following requirements.

Normal office lighting levels will be adequate, i.e. around 500 Lux, and an intermediate or ‘warm’ fluorescent colour (equivalent colour temperature 3000-4000 Kelvin) will give acceptable pictures and emit a comfortable light for the participants.

11.1.3 LED lighting ‘White’ LED lighting is an acceptable lighting choice, subject to the following requirements. Currently only Phosphor-LED arrays are allowable.

Brightness Normal office lighting levels are adequate, i.e. around 500 Lux.

LED flash rate The following regimes are considered acceptable:

• LEDspermanentlyilluminated(i.e.LEDdutycycle=100%)

• Emulationofcharacteristicsoftypicalfluorescentlighting,approximately:LEDflashrate:100HzLEDdutycycle:>50%LEDpersistence:>3ms



11.2 Window treatment A room without windows is preferred as a videoconferencing space.

However, if a room with windows is the only option, window treatment will be necessary to control lighting conditions. In particular:

• no direct sunlight shall enter any part of the room at any time of the day or year; • glare and reflections onto the screen(s) must be prevented; • glare from behind the screen(s) must be prevented.

The preferred method of window treatment is heavy curtains which block out all light from windows. The drapes shall have a solid colour, without pattern, in appropriate tones and loosely gathered while still being in keeping with the tones of the room.

Curtain/blind colours shall be as defined in section 1.1 of ICT Resource 2.3.2. Drapes may be of contrasting colour to the wall, but drawn from the same approved palette. Fabrics shall not be of course weave.

Venetian (and micro-venetian) blinds are NOT to be used under any circumstances. Vertical (venetian) blinds are NOT to be used under any circumstances.

11.2.1 Automated block out blinds If heavy curtains are not possible due to building design, it is possible to use block out blinds instead.

11.3 Colour scheme

11.3.1 Prohibited colours, patterns and finishes Prohibited colours, patterns and finishes in-shot:

• Brightred,darkred

• Black,White

• Reflectiveandhighglosssurfaces

• Finelineandgridpatterns

• Venetianblinds(vertical,horizontalandmicro)

• Courseweaveinfabrics

11.3.2 Table tops White (and near white) table tops are NOT acceptable.

Black (and other dark) table tops are NOT acceptable.

High gloss table tops are NOT acceptable.

A lightish colour (e.g. light oak wood-grain), but not white, is preferred, so as to infill shadowing under participants’ faces. Mid brightness colours are also acceptable (e.g. mid-brown wood-grain).

Wood-grain, two-tone and solid colour surfaces are all acceptable. Table colour should contrast with wall colours.



11.3.3 Wall treatment In order to provide a high quality image, the subject needs to have sufficient contrast with the background. The wall that the camera(s) is facing toward and the side walls shall be painted using neutral colours from the palette as given in the Cisco Project Workspace Guide. For contrast and interest, the side and rear walls may be painted in different colours.

Matt paint shall always be used to minimize reflections.

11.3.4 Wall behind LCD panels The wall behind the LCD panels shall be painted using a neutral colour from the palette as given in the Cisco Project Workspace Guide.

11.3.5 Ceiling Where video projectors are employed, so as to minimize re-reflection of light from the ceiling back onto the image surface, the ceiling above the Front-of-House area (AV6 and AV8) shall be painted using a neutral colour from the palette as given in section the Cisco Project Workspace Guide. Paint type must be zero-gloss ceiling type paint.

In all other situations, ceiling areas shall be painted zero-gloss ceiling white.

11.4 Interior decoration Videoconference rooms should strike a balance between looking as natural and normal as possible, while not having excessive detail, distractions or features that will disturb correct operation of the camera. In particular:

• Finegrid-patterns(e.g.onfabrics,blinds,curtainsandtabletops)mustbeavoided(thesegenerateunacceptableinterferencepatternsinthecamera–duetoaliasingbetweenthefabricgridandtheimagesensor’sinternalgridstructure);

• Detailatdistancesdifferentthanthesubjectsaretobeavoided(thesecancausetheauto-focuscameratofocusinthewrongthings;

peopleandthingsintheexternalworld(verydistractingfortheviewers).

High gloss surfaces must be avoided to minimize reflections. In particular paintings/prints/photographs and whiteboards (which also have high gloss surfaces) should be angled so as to not directly face the camera (so that they do not reflect the screen image back



into the camera. Protective glass covering paintings/prints/photographs, if any, should be replaced by non-reflective matt glass.

11.5 Signage Wall signage is optional. Where signage is employed, only the official Deakin crest and/or corporate logo shall be used, using their correct colours, fonts and layout. Where not specified by the official artwork, the background colour shall be the wall colour. The signage may identify the venue in 5 words as:

“Deakin University Australia

<suburb/town/campus> campus”

Where signage is employed it shall be sufficiently large to be easily read even when the camera is set to its widest shot.

11.6 Acoustics and acoustic treatment

11.6.1 Acoustic isolation The overall acoustic design shall provide a minimum 45 dB (preferably 50 dB) attenuation of sounds into or out of the room. Note this is the total over all paths, whether through walls, doors, ceilings, windows or direct transmission through floors or building fabric. Wall insulation must take into consideration sound bleed through ceiling spaces above walls – suitable ceiling insulation and/or sound blankets in the ceiling space above walls must be fitted so as to preserve overall isolation requirement. For example, if there are two equal dominant sound paths through wall and ceiling each must achieve 53 dB on its own so as to preserve an overall attenuation of 50 dB.

11.6.2 Noise Ambient sound in the room shall not contain any distinctive characteristics such as tones or fluctuations. Air conditioning, external noise and other plant noise shall not exceed NR35 as defined by AS 2107 2000.

Openable windows are unacceptable; if unavoidable these are to be fitted with heavy curtains, and both the windows and curtains shall be kept fully shut during videoconference sessions.

In particular, noise floor target range, to be measured with HVAC systems running, is 30 to 40 dBA and must not exceed:

• 45dBAanywhereintheroom;and• 40dBAatanyofthemicrophonelocations.

11.6.3 Reverberation Reverberation times are defined at AS 2107 2000.

In particular, reverberation time target range is 0.3 to 0.4 s and must not exceed:

• 0.6sforcontrolledspaceswithbothfixedfurnitureandfixedmicrophones• 0.5sforuncontrolledspaceswithflexiblefurnitureand/ormovablemicrophones



11.6.4 Acoustic treatment Acoustics of the space is very important for successful videoconferencing and will be determined during the audit phase, pre installation and will specify the following acoustic treatment under these circumstances:

Acoustic dampening: is required in rooms that have significant echo, exceeding the above reverberation limits.

Noise cancellation: is required when noise floor exceeds 40 dBA. As a last resort if natural noise floor cannot be brought within limits specified here by other means, noise cancellation shall be achieved through the use of the ClearOne Converge Pro 880 DSP, but only if: the natural noise floor is below 50 dBA everywhere within the room; AND the noise is of a type that can be effectively reduced (e.g. continuous white noise but not background crowd noise).

The device shall be adjusted so as to deliver a noise cancellation of no more than 10 dB.

A natural noise floor above 50 dBA is unacceptable and cannot be rectified electronically

Echo cancellation: is an integral requirement of any videoconference system; it is preferably performed natively within the codec; or alternatively within a ClearOne DSP where fitted.

11.7 Table layouts The arrangement of tables and chairs can significantly affect the videoconferencing experience. The following layouts illustrate different videoconferencing installations.

11.7.1 AV4 – Meeting room Preferred layouts (‘immersive telepresence’ style):

• Widearc• Wide‘V’• Widetrapezoid• Widerectangle• Absoluteminimumdepthforwideformattables750mm(preferredmin900mm)

Acceptable layouts: • ‘U’,halfoval• Square• Longtrapezoid

Non-preferred layouts (poor local and videoconference sight-lines):

• OvaluseHalfovalorotheracceptablelayoutsinpreference

• LongrectangleuseTrapezoidorotheracceptablelayoutsinpreference

Absolute minimum width for Long format tables 1000 mm (preferred min 1200 mm)



Type of space Acceptable table layout

Small meeting room (AV4)

Videoconference unit wall mounted, e.g. above credenza, persons seated on small round, oval, square or rectangular table:

Larger meeting room (AV4)

Preferred: Videoconference unit wall mounted, wide arc, open ‘V’ or wide rectangle table:



Acceptable: Videoconference unit wall mounted, ‘U’, half oval, square, short rectangle, or trapezoid table, e.g.:

Non-preferred: Videoconference unit wall mounted, long rectangle or oval table:



11.7.2 AV6, AV8 – Teaching spaces Type of space Acceptable layout

Teaching space (AV6, AV8)



11.8 Camera and viewing angles Cameras will be positioned centred with respect to both the table and the displays and angled as per the following specifications:

Cisco Spark Room Kit Viewing Angles



Cisco Spark Room Kit Plus Viewing Angles



If SX80 with Precision HD Camera is used:

Type of space Standard camera arrangement Meeting room (single screen) (AV4)

The single Precision-HD Camera shall be positioned at a height immediately above (not below) the display. This ensures that the eyeline as viewed from the far-end is close to and a little downwards from eye-to-eye. This is preferable to appearing to look above eye-to-eye – it is normal for people to be looking a little downwards (e.g. looking at papers), indeed this is expected respectful behaviour in some cultures, whereas looking over someone’s head always appears decidedly odd.

If a camera placed above the display produces camera angles that are too acute (as defined at section 11.9.4), this indicates that the screen is mounted too high and/or the chosen screen size is too large for the size of the room – in which case a smaller screen is required – choose from the table at section 11.9.1 below. If this still produces acute camera angles, upgrading to a dual screen system is indicated, with camera mounted at correct height between the displays as below.

The camera shall automatically adjust to focus on participants.

Meeting room (dual screen) (AV4)

The single Precision-HD Camera shall be positioned at a height as determined by the formulae at section 11.9.4. Usually between the displays, or sometimes immediately above the displays, but not below the displays.

Teaching space / Lecture Theatre (AV6 / AV8)

Teaching spaces shall have at least two cameras. One shall be positioned at the rear of the venue, directed toward the presenter. The other camera shall be mounted in the centre of the front wall (between dual projected images), directed toward the audience.



11.9 Viewing distance and viewing angles In selecting screen(s) for the room layout, the following design rules shall be observed:

11.9.1 Single display Design rules:

• Minimumviewingdistance=2xImageHeight• Maximumviewingdistance=6xImageHeight• Maximumviewingangleoffaxis=45°frommiddleofimage(preferred)

• Maximumviewingangleoffaxis=45°fromnearestedgeofimage(absolutemaximum)• ReferspecialrulesforAV2(EX90deployments)atSection5.2.1.

For the standard LCD panel sizes this equates to:

[*] The worst off-axis view occurs at the front seating position – these figures can be exceeded when seated further back

[**] Measured perpendicular to the presentation surface (i.e. on-axis)

11.9.2 Dual display In video conference applications, dual displays are used to display different images, therefore adequate view of both screens must be maintained, as if both screens are part of one very wide (32x9 aspect ratio) display.

Relevant interpretation of design rules: • Minimumviewingdistance=2xImageHeight(absoluteminimum)• Minimumviewingdistance=1xOverallDisplayWidth(preferredminimum)• Maximumviewingdistance=6xImageHeight• Maximumviewingangleoffaxis=45°fromcentreoffarthestimage(preferred)

11.9.5.3 AV6 and AV8 Camera 1 (front, audience facing camera) should ideally follow the same rules as above for AV4. Where this is not possible (e.g. clearance required to minimize risk of bumping, damage theft, camera shall be between 2100 mm and a maximum of 2500 mm AFFL.

Camera 2 shall be mounted between 2100 mm and a maximum of 2500 mm AFFL. For AV6, camera is normally mounted on the rear wall. For AV8, camera should be mounted sufficiently forward in the theatre so that it can be zoomed in to capture a head-and-shoulders close-shot of the presenter – this could require mount descending from the ceiling, which must be sturdy and vibration free. Laterally, the camera should be positioned so that the presenter, when at their normal position behind the presenter’s desk, is looking directly towards the camera when looking at the exact centre of the auditorium.



12 Commissioning and Handover 12.1 Commissioning Appropriate commissioning of equipment and systems shall be carried out by the contractor to ensure that the as-designed performance, functionality and reliability of equipment and systems is proven and documented prior to project handover.

Four sign-off stages by DeS staff are needed to be carried out prior to handover.

1. Cabling: Inspection that cable runs have been completed satisfactory.

2. Termination: Inspection that proper termination has been carried out on all cabling.

3. Equipment install: Inspection that equipment has been installed correctly

4. Operation and training: Space is shown to be operating correctly. Check lists will be provided

12.2 Handover Final handover of work will be completed after satisfying appropriate sign-off stages of work. On completion, the contractor will supply block diagrams and full documentation as described in this document.

YC Also known as S-video is an analog video interface that carries the video data as two separate signals: Y luma (luminance) and C chroma (colour). The two chrominance (colour difference) signals are modulated (multiplexed) into the one signal, but the Y signal is kept separate. This avoids the Y-C cross-modulation interference typical of Composite video.

YC/C An video interface that can be configured for use in either YC (e.g. 2xBNC) or Composite (e.g. 1xBNC) modes
