  • Transcript

    • 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
