Matching the Right IP Solution to Your Business / OrganisationRequirements

Presented to :Next generation CCTV Conference 2008

4th November 2008

Agenda

• What is an IP system ?• Knowing what you want from your system

(IP Operational requirements)• Deciding whether IP is for you (IP benefits,

disadvantages and Pitfalls)• Analysing alternative approaches to IP

adoption• Assessing what is on the market and

making sense of what suppliers are offering

Key Stages in Specifying CCTV

HOSDB - (Google “CCTV operational requirements)

Level 2 Operational Requirement

• Camera factors– Level of detail (%R), Lighting, target speed

• Live viewing– Who, where, frame rate, image resolution, quality

• Recording/Review– Frame rate, image resolution, quality, retention

periods

• Integration– Systems, desired actions/responses

Design Considerations - Cameras

• Camera– IP Cameras, Hybrid IP cameras or Analogue

cameras with IP transmitters

• Encoder– Frame rates– Type of compression, performance– WAN and recording streams– No. of supported streams– Latency (PTZ / voice comms)– Environment, space, temperature– TCP (error checking)/UDP (fire & forget)– Multicast support

Design Considerations - Network

• Whose network ?• Total bandwidth• Available bandwidth• Traffic cohabitation

– Prevent video hogging bandwidth– Prevent other traffic causing video glitches

• Traffic prioritisation (QOS)• Multicasting• Network Security

– Secure network, secure CCTV overlay

• Storage requirement– Frame rate/resolution/compression = bandwidth– Bandwidth (Kbps)/8 * retention period(s) =

storage (KB)

• Compression– MPEG4, H.264 benefits

• Recording Platform– Redundancy (RAID, dual PSU, NIC)– Resilience

• Review Software– Post event analytics (Google for CCTV)

Design Considerations - Recording

A strong business case if……

• Large Systems (>100 cameras)• Mission Critical• Multiple Monitoring and Review locations• Wireless transmission• Existing Network• Regional (Telco Network)• Integrated Systems

• Island Site– <300m across, route owned– E.g. Warehouse, office

• Campus– 300m>1500m, route owned, multiple buildings– E.g. hospital, shopping centre, airport

• Metropolitan– 1500m>10Km, route not owned– E.g. town centre, UTC

• Regional, National, International– >10Km transmission route not owned– E.g. Rail TOC, Highways, multi-site business

System Geography - Site Scenarios

• Equipment more expensive• Complex configuration• Transmission delays (latency)• Inferior live image quality• Environmental factors• Poor low-light performance and dynamic

range

IP Drawbacks and Pitfalls

• Analogue Cameras (+ IP Transmitters)– Low light, high contrast, interoperability, existing– Increased cabling, no remote management

• Hybrid Analogue Cameras (Integrated IP)– Low light, high contrast, less cabling– Interlaced video, 90m

• IP Cameras– Megapixel, progressive scan– Require good even lighting, bandwidth & storage requirements high

IP System - Camera Choices

• PAL Resolution– “Recognition”– 50%R

• HD (720p)– Recognition– 40%R

• HD (1080p)– Recognition– 27%R– 3.7x horizonal

resolution

Megapixel (HD) Cameras

Where to Start ?

• Manufacturer– Will naturally push own product– May not be the best for your application– Generally don’t understand O/R

• Consultant– Costly but Impartial Advice– Few CCTV consultants have IP knowledge

• Integration partner– Hands-on expertise in systems– Should assist with O/R & technical spec.– Advice not wholly impartial but free

Selecting equipment/Manufacturer

• Basic requirements– Reliable equipment– Useable intuitive software– Financially stable– Large installed base

• Desirable Features– Efficient compression (quality/bandwidth)– Bandwidth control– Industry standard recording platform– Evidence location tools– Integration capability

Selecting an integrator partner

• Compliance– NSI (NACOSS), BSIA Members/CoP

• Analogue CCTV Experience– Informed choice, expertise still relevant

• Technology Competence– Experience, Strategic Partnerships

• Understanding of Networks– Bandwidth Control, Unicast/Multicast, TCP/UDP– Managed/Unmanaged Infrastructure

• Successful IP CCTV Installations– Ask for client references for similar projects

In a nutshell……………

• Operational Requirements should be the driver, not technology

• Get expert help with O/R and specification – (manufacturer, consultant, integrator)

• IP Business case– Shared network, geography

• Technical Considerations– Analogue or IP cameras– Compression
