Video Technology Overview

Analog Video Optical transmitters modify signal output based on video content

Modifications include amplitude (AM) or frequency (FM)

Most commonly used for security and surveillance applications

Tried and true technology and still the lowest cost option today

80% + market share today for new installations

IP Video Video camera automatically encodes the video output into IP packets

Power over Ethernet technology benefits

Gaining popularity in security and surveillance applications

Estimated to gain 50% + market share by 2010


Security video cameras offered in one of two formats: Analog video

IP Video

Analog or IP video camera functionality falls into two broad categories: Fixed

Typically for entry doors, hallways, gates, etc.

Pan-Tilt-Zoom (PTZ)

Typically used in retail, casinos, etc. where the ability to change camera view is required and the cameras are actively monitored/controlled


228 meter (750ft) distance limitationon coaxial cabling runs

Typical Analog Video System

100 meter (328ft) distance limitationon all UTP cabling runs

Typical IP Video System

Ever increasing reach of surveillance Leading to quality, bandwidth, and transmission distance issues

Beyond the reach of traditional copper (coax or UTP) cabling

New camera locations may require new cabling

Many IP camera installations co-exist with analog camera networks Cabling mismatch if upgrading cameras

Extended reach of network beyond original design for new cameras

Video Security & Surveillance Realities

Copper-based cabling limitations

Limited transmission distances Coaxial cable < 228 meters (750 ft.)

UTP cable < 100 meters (328 ft)

Requires more equipment or signal conditioning / amplification to increase distance

Susceptible to electrical interference Noise, high voltages and ground faults

Quality and security risks Quality effected by distance and interference

Copper-based cabling easy to tap into

Allows for extended transmission distances Multimode cable < 2km (1.24 miles)

Single mode cable > 2km

Smaller size, less weight and better tensile strength Easier installation when pulling through conduit or overhead cable trays

Usually existing as network backbone in vertical risers and between buildings Reduce cost by utilizing existing fiber infrastructure

Improve quality, bandwidth and distance of video system

Fiber Cabling Benefits

High degree of security difficult to tap into or interfere with

Immunity to electrical interference such as: Electromagnetic interference (EMI)

Radio frequency interference (RFI)

High voltage interference caused by:

Fluorescent lights

Card access door strikes

Outdoor lighting systems

Induced voltages caused by ground potential differences between locations

Occurs in over 50% of all video security systems

IEEE 802.3af = Power over Ethernet (PoE) specification

The ability of a device to transmit power as well as data on the UTP cabling link to an end device (15.4 watts)

Typical end devices are IP cameras, wireless access points and IP phones

IEEE 802.3at = Power over Ethernet Plus (PoE+) specification

24 Watts

More power for devices like PTZ IP Cameras

Backwards compatible with 802.3af equipment

IP Video andPower over Ethernet Technology

PoE greatly simplifies camera installation and is a huge benefit to IP network camera installations vs. analog equivalent

No need for an electrician to install power receptacle in a difficult location

Saves time and $$$

Most IP cameras can be Powered Devices (PD) using PoE technology

Switches can be Power Sourcing Equipment (PSE)

PoE Injectors (also known as Midspan PSEs) simply insert power onto a CAT 5 Ethernet cable, without affecting the data.

Media Converters can be Power Sourcing Equipment (PSE)

PoE Media Converters, in addition to PoE Injectors, allow the addition of PoE capability to existing CAT 5 Networks while also converting from Fiber.

Power over Ethernet Technology Enables IP Video

POE Network Switch

100 meter (328ft) distance limitationon all UTP cabling runs

Typical IP Video System w/ PoE switch

100 meter (328ft) distance limitationon all UTP cabling runs still applies

PoE Injectors

Can the benefits of fiber be realized while still taking advantage of PoE? PoE media converters can provide the data link as well as inject the power

onto the UTP interface to the camera, while providing the fiber link back to the central location

Fiber Integration in IP Video Networks

Typical temperature requirements: -40 to +75 degrees C Enclosure mounting with no temperature control Typically 100 230 VAC or 24 to 48 VDC Serial interfaces most common today: RS232/422/485 E.g. NEMA-TS2 for Traffic Control

Operating Temperature: -34 to +74 C Emissions Class A Transient voltage suppression and immunity higher than for office-grade

equipment

Meet the above requirements with Industrial Ethernet products

Outdoor Applications

What is Industrial Ethernet?

Industrial Ethernet Generic term to cover communications within non-office open-

architecture environments Environment will be customer specific

Three Broad Environment Classifications: Factory Environments Outdoor (e.g. Ethernet / Traffic Control) Lite, or extended temperature

Major Characteristics of Industrial Ethernet

DIN rail mounting Extended operating temperature range Designed for passive cooling (Fan-less) Rugged design, especially the case Rugged connectors in addition to RJ-45 (e.g. M12) Higher Ingress Protection rating to protect from dust / moisture Edge-based (where the devices are) Very long deployment lifetimes requiring higher reliability

Video Encoder / Decoder Also known as Video CoDec or Video Server

Analog video input on coax

May include serial port for PTZ functionality

Video stream is encoded and compressed (MJPG, MPEG2 or MPEG4) into IP packets

Video output over UTP (10/100Base-TX) Fiber optic port (100Base-FX) are rare, may need to use media conversion

Managed web-browser interface allows for access from any PC

Can I Incorporate My Analog CamerasInto My New IP Video Network?

Analog/IP Video Over Fiber Network

Many video security and surveillance networks are undergoing transformation

Conversion from Analog-based to IP-enabled video networks

Analog and IP cameras will inevitably co-exist

Continue to maintain existing Analog network? Many security networks will continue to be analog-based

Distance reduction when moving to IP video will impede copper-based overhauls

Video Servers / Codecs can ease this transition Enjoy the benefits of IP camera technology without replacing existing analog

cameras

Hybrid Video Surveillance Networks

Hybrid Video over Fiber Network

Extended reach of video security and surveillance networks Leading to quality, bandwidth and transmission distance issues

Cameras may be located beyond the reach of traditional copper cabling

Or beyond the reach of the original network design

Fiber can provide many benefits Increased transmission distances extended reach

Immunity to electrical interference improved video quality

Greater security less risk to tampering

Smaller, lighter and stronger easier installation

Media Conversion can ease the transition to fiber Utilize existing network security equipment save on investment

Benefits of PoE can still be utilized
