  1. IP Video Surveillance Presented by Sridhar Ponugupati

  2. Traditional DVR System Coax Cat 5e Network Switch Cat 5e DVR

  3. IP Video System Analog Cameras IP Cameras Coax Encoder Cat 5e Network Switch Cat 5e Storage Client Workstation NVR

  4. System Components

  5. Encoders • Sometimes called Video Servers • Convert analog cameras to IP • Usually 1 or 4 camera inputs • Alarm Inputs and Outputs • PTZ Control for most brands • Audio Inputs Available

  6. IP Cameras • Connect directly to Ethernet network • Wide variety of models available for all applications Fixed Bullet Mini-Dome Pan/Tilt/Zoom

  7. Most cameras have high resolution available • 640 X 480 (4 CIF) • 720 X 480 • MegaPixel IP Cameras are available • Up to 5 MegaPixels

  8. IP cameras with megapixel resolution allow for highly effective digital zoom capability and virtual pan and tilt functionality 640 X 480 Image 1900 X 1200 Image

  9. Power Over Ethernet (IEEE 802.3af) • Less cabling • Can be added using injectors (mid-spans) • Use existing Voice over IP switches

  10. Various video compression methods are available • Motion JPEG • MPEG4 • H.264 • Wavelet • Most cameras only have one or two types of compression available

  11. The camera can be used as connection device for other types of data: • Alarm Inputs • Alarm Outputs • Audio (Bi-Directional) • RS-232

  12. Many models have card slots available for wireless Ethernet adaptors or local storage • Many options are available for wireless connection to cameras

  13. Most models have built-in motion detection • Some have built-in video analytics • Intelligent motion detection • Abandoned object

  14. NVR • Software Solution • Installed on a non-proprietary server • Advantages: • Customers can source their own servers, workstations, and storage devices • Can be less expensive in cases where there are a large number of cameras being recorded at a low frame rate • Virtually all IP cameras are supported • Virtual matrix switch software is available

  15. Disadvantages of software NVR • Can be more difficult to install and service • Higher total cost in most cases • Limited integration with access control • Customers can buy their own servers and storage

  16. NVR on proprietary hardware • Software is pre-installed on hardware provided by the CCTV manufacturer • Internal or external storage is also usually provided by the CCTV manufacturer • Advantages • Easy to design the system • Easy to install and service • Many of these types of NVRs can be integrated with access control systems • User interface may be similar or identical to DVRs • Well developed suite of features inherited from DVR technology

  17. Disadvantages of proprietary NVR • Usually support a very limited variety of cameras • Customers that desire IP surveillance systems may not want to be locked into proprietary server and storage hardware

  18. IP Video Challenges • Hardware Cost • $300 to $500 more per camera • Requires a higher level of skill and training to install • Introduces a different group of competitors • Internet Resellers • Network VARs

  19. Where to use IP Video • Gigabit Ethernet Backbone • Schools, office buildings, etc. Existing IP network infrastructure can be utilized

  20. Large facilities or campus environments • Server pulls video over network backbone • Long distance “home-run” cabling is not required.

  21. Cameras are widely distributed • Locations are connected via a WAN • Recording is done at a central location

  22. More Applications • Customer needs high resolution images • Most surveillance grade IP cameras can provide higher resolution images than DVR • MegaPixel cameras can provide very high quality images • Remember that they will require at least 20 times more storage space than a standard camera • Customers with the future in mind • Customers with a strong IT department
