The document presented by Simon Adcock at the Next Generation CCTV Conference 2008 provides an overview of implementing IP-based CCTV systems, detailing operational requirements, camera specifications, network design considerations, and the benefits and pitfalls of IP technology. It emphasizes the importance of understanding business needs and selecting the right equipment and partners for successful installation. Additionally, it highlights various scenarios for deployment and outlines the necessary evaluations to ensure a robust security solution.

1. By Simon Adcock, Managing Director, ATEC Security & Communications Matching the Right IP Solution to Your Business / Organisation Requirements Presented to : Next generation CCTV Conference 2008 4 th November 2008

2. 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

3. What is an IP CCTV System? analogue IP transmitters IP Cameras IP Video Bridge IP Connection

4. Key Stages in Specifying CCTV HOSDB - (Google “CCTV operational requirements)

5. 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 Reproduced by kind permission Home Office Scientific Development Branch

6. 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

7. 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

8. 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

9. 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

10. 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

11. 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

12. 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

13. PAL Resolution “ Recognition” 50%R HD (720p) Recognition 40%R HD (1080p) Recognition 27%R 3.7x horizonal resolution Megapixel (HD) Cameras

14. 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

15. 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

16. 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

17. 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 In a nutshell……………
