What is network video surveillance


Published on

IP Video Surveillance and MegaPixel Technology

The video surveillance market is growing constantly, driven by increased public and private security concerns, as well as a technology shift. The transition to network video is a reality as customers take advantage of flexible, industry standard systems for security and video surveillance. As security management over the IP network expands and intelligence capabilities move out to network cameras, systems can scale much more easily. This move to open systems empowers a much more productive and cost-effective means of surveillance than was ever possible.

MegaPixel IP Surveillance Camera Resolutions:The resolution chart above show traditional analog camera resolutions compared to todays 1080p HD video resolution standards. A one megapixel camera today equates to more than four VGA quality cameras combined. This means you can cover more area with a higher level of detail using less cameras and therefore reducing installation, cabling and management costs. It also allows for the new world of “Virtual Cameras”.

What is network video surveillance

  1. 1. MegaPixel IP SurveillanceVideo Explainedby Exacq-VideoSurveillance.com
  2. 2. Resolution• MegaPixel Technology allows for detail thatwas once un-imaginable
  3. 3. VGA Analog vs MegaPixel• A (1) one Megapixel Surveillance Camera hasthe resolution of 4 VGA quality Cameras andup to 8 CIF Analog Cameras
  4. 4. Camera Inputs and Outputs• Focus and Focal length adjustments are the key toclear video• Built in microphones, 2 way audio and I/O portsare additional benefits
  5. 5. Pixels Per Foot Calculations• Axis Camera Configuration tools provide accuratepx/ft calculations• 160 px/ft is a European Standard admissible incourt for identifying a face.
  6. 6. Edge Storage• Edge Storage enabled security camerasallow memory cards to store recordedvideo.• ExacqVision offers managementsolutions to optimize recorded videowith minimal storage• Some video recording tools include:recording on motion, triggers, videomasks, scheduling, frames per second,resolution, multi-streaming and virtualcameras.
  7. 7. Security Gate Examplefor Edge Storage• Security Gates do not normally have internet access andEdge storage provides a way to record the video on a SDCard• The 32GB SD card will write over itself within a set numberof days.• Below are 2 scenarios, one camera is set to record for 14days on 32GB Memory Card. The second camera will writeover itself every 7 Days. The difference is the Frames PerSecond, % of motion and the resolution.
  8. 8. Popular MegaPixel Cameras• Axis M-1054 & Axis P-1344
  9. 9. 20 MegaPixel 180 Degree Camera• Potentially replaces 5-10 analog cameras
  10. 10. Video Encoders• Take advantage of analog infrastructurealready installed and covert them to IP with avideo encoder
  11. 11. Management Software
  12. 12. Fixed Dome & PTZSurveillance Cameras• Axis Communications Product line has acamera for every situationPTZ
  13. 13. Wireless• Wireless IP Camerasare just beginning tocome in 1 MegaPixeland above resolution• H.264 videocompression allowsfor high definitionvideo to bestreamed a wirelessrouter
  14. 14. Network Video Recorder• A NVR is a IP Camera storage device with a set amount of HardDrive Space• Depending on the amount of cameras being recorded, FrameRates, amount of motion, and resolution a NVR is built toaccommodate any number of Days of recorded video.
  15. 15. Depth of Field• Understanding your target depth of field should help you choosethe correct IP Camera• Use Axis Configuration Calculator for each camera to help
  16. 16. Event Triggers• Event triggers are either notifications or actualactions the video management system cancommand
  17. 17. Audio
  18. 18. Audio Modes
  19. 19. Input / Outputs
  20. 20. Storage Calculation
  21. 21. Network Video Installations• Haverford System, Inc• Authorized ExacqVision Partner• Authorize Axis Communications Partner
