Designing Wireless Solution for Video Security


Wireless vs Wired

If the Wire is where you need it, when you need it, at a price you can afford and provides the capacity required…..then use it!

However….Life is rarely that easy

Wireless offers the capability to provide

Rapidly Deployed Camera Locations

Provide Video coverage in hard to reach areas

Potential for significant cost savings over wired solutions

For new installations –

the preference is becoming Wireless 1st and Wired 2nd


Designing Hierarchical Solutions

Wired Solutions are typically designed as part of a functionality hierarchy – Client, Access/Edge, Distribution, Core/Backbone

So why should a wireless network design be any different?

Common Design Misperceptions

Security“Wireless networks can be hacked….”

Availability“Wireless networks are much more prone to effects from the

environment than wired networks…”

Capacity“Wireless networks have far lower bandwidth than wired

networks…”

Flexibilty“You are constrained in how powerful your signal can be,

significantly reducing the distance that you can transmit…”


Security

Question – What type of security do I need?

Because wireless has a perception of being vulnerable

Enterprise products are designed with high-levels of security in mind….unlike many wired products

Considerations

How vulnerable is the physical deployment?

How long is my asset in place?

What level of encryption should or can I use?

How does the wireless link fit into my End-to-End Security Eco-system?


Availability

Can I Achieve 99.999% availability with a wireless solution?

...YES!

…but just like wired solutions it’s a cost vs requirement argument

Considerations Confirm what frequencies are available for deployment

Conduct RF and Physical Site Surveys

Consider potential local environmental changes

Deploy overlapping Camera coverage positions on different frequencies

Create resilient Backbone links for Aggregation Connections

Create a Frequency plan BEFORE you deploy

Designing availability for wireless faces similar challenges as wired

Comes down to a cost vs. requirement argument and proper design


Capacity

What bandwidth do I need today and what do I need tomorrow?

Considerations Agree Video Quality/Camera Specification required – and get it in writing!

Focus on MPEG4 or H264 codec solutions at the edge

Use built-in analytics and local storage solutions to minimise traffic loads

Design Distribution and Backbone solutions with future growth in mind

Reserve bandwidth for downlink communication – critical for PTZ response

Implement QoS and traffic shaping for critical cameras

Capacity is a network-wide system consideration

Not just how much bandwidth I need at one camera location


Flexibility

Where do I need my camera and for how long does it have to be there?

Considerations Location is key - Expensive/Intelligent cameras are useless unless deployed

where needed

Deploy camera Low-site and Wireless backhaul at High-site

Consider Mesh WiFi solutions for localised deployments that need mobile user

access – but use high-capacity PTP links for backhaul

Wireless solutions offer significant flexibility for re-use - but Pre-plan your

deployment locations

Wireless offers significant advantages over wired solutions with regards to Flexibility

But only if the network has been planned correctly


Designing Wireless Video Surveillance Networks

Architecture Create Hierarchical Wireless Network designs

Apply apporpriate levels of Security, Availability, Capacity and Flexibility as

needed

Security Consider the End-to-End Security Requirements

Make the Security applicable to the requirement or the asset

Don’t neglect internal security requirements

Availability

RF and Site Planning is a key requirement

Don’t assume the environment never changes – perform ongoing network

evaluation check

Don’t over-plan link availability if the asset or traffic doesn’t warrant it

Capacity Don’t just plan for today – plan for growth

Lock down and agree camera specifications

Utilise Intelligent Analytics and Effecient CODECs to minimise Bandwidth impact

Flexibility

For rolling networks – pre-install permanent mounting/power requirements to

minimise tear-down and put-up times.

Plan aggregation links with moveable cameras locations in mind

Assess the need for mobile access to the network

Operation Pegasus : Labour Party Conference Bournemouth

Stats• Nearly 20,000 attendees

• More than 20 different protest group demonstrations

• Gordon Brown’s first political conference as Prime Minister

• Heavily restricted access before and during the event

• Tried and tested roll-out procedures for Security Enforcement

Operational Objectives• Enhance Police Surveillance Capabilities

• Provide “on-the-ground” mobile surveillance for protest marches

• Capture and record high-quality video for later analysis

• Allow “on-the-ground” officers access to live video-streams

Operational Challenges• Off the shelf technology

• Do not integrate or interfere with policing operation around conference

• Tight-timescale –

First site survey August 15th, Operational “go-live” September 17th

Bournemouth vs. Leeds Football Match

Stats• Previous match resulted in severe vandalism & damage to Bournemouth city centre• First time they have played since this incident• Large scale operation run by Dorset Police

Operational Objectives• Provide video CCTV Surveillance at high-risk locations• Provide video surveillance “on-the-ground” around the stadium• Provide tracking of police officers• Capture video images and re-distribute information to police officer handsets

Operational Challenges• Re-deployment of equipment from Operation Pegasus• Low light conditions require Infa-red video around stadium• Integration with Airwave Dimetra network• Tight timescale –

De-commission Operation Pegasus October 5th, Re-deploy for Operation BvsL “go-live” November 3rd
