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
    In a nutshell……………
