IP Camera Market Growth

• Important to Match the Camera to the Requirement
  • A Mega-Pixel Camera will produce a superb quality Image, but it will also use up significantly more bandwidth than a camera using 350k Pixels. If you don't need Mega-Pixel quality, don't get it.
  • If you don't need PTZ, don't pay for it.
  • If you can run cables, don't pay for wireless; wired is always better then wireless.
• Camera Selection Choices
  1. 1) CCTV (Closed Circuit TV)
     1. Video Server
     2. Video Capture Card
     3. Wired - Video/Power
  2. 2) IP Cam
     1. Wired - PoE
     2. No Capture Card/Video Server needed
     3. Easily viewed over LAN
• Camera Considerations
  • Need Power
    • Power Consumption
    • POE - Power Over Ethernet
    • Even "Wireless" cameras need power
    • Use a "wired" camera w/PoE
  • Wireless
    1. IP Cameras connected to a WAP or Mesh Network
    2. Only use as Required
  • IP/WebServer Camera
    • Cameras accessed via Ethernet/Video Capture
    • PC Camera (USB) N/A for Video Surveillance
  • Options/Considerations
    • Lighting Critical for Image Quality
    • Day/Night - Infrared - Night Vision
    • Minimum Illumination
    • In-Side vs Out-Side - Weather Proof Housing
    • Ruggedized Housing
    • Mount Types
    • PTZ - Pan - Tilt - Zoom (Optical/Digital)
    • Pan/Tilt Degrees
    • Manual Zoom
    • Lens Size/Type
    • Number of Pixels
    • Resolution
    • FPS - Frames per Second
    • Compression
    • Color vs BW
    • Focal Length - Field of View - Calculator
      • Distance Example - 4m - 1/4' Lens
      • A "Normal" Focal Length on a 35mm Camera is approx. 50mm - it produces the same perspective as the human eye
      • 18mm to 35mm is considered wide-angle
      • 80mm to 500mm is considered telephoto
      • These numbers are not necessarily the same, however, a lower number still produces a wider view (wide-angle) then a higher number
    • Audio
    • Sensors

     

• General Video Surveillance Considerations

  • NO Guarantees that any specific activity will be recorded

  • General Coverage is provided, but NOT every area is normally covered

  • Many of the Cameras are PTZ and the actual recording will depend upon the position of the Camera at any given time

  • Detail/Clarity will vary with Distance from Camera

  • Generally No Mug-Shots; some exceptions – luck, doors, etc

  • Patrolling Options: broad coverage, may miss specific actions, but will view results; provides a general sense of security (all is well), vs. monitoring a specific area.

  • Lighting affects quality of images; Time of day, shadows, night, etc

  • Better the Image; the more disk space required for recording

  • Video Servers more sensitive to Network Traffic

• CCTV Video/Wireless Devices
  • Video Only - NO PTZ Controls
  • Not Recommended
