CCTV (closed-circuit television) is a surveillance system

: In which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere.

 

HD-SDI is a new technology in CCTV that offers High Definition 720 and 1080P resolution video over standard Coax cabling. 
These HD-SDI CCTV products are ideal for upgrading existing analogue CCTV Installations where higher resolution HD images and performance are required.

SDI is the transmitting technology through the 75ohm coaxial cable by serializing the video signal that is not compressed.
The video signal that is transmitting through SDI is a kind of digital signal. Therefore, contrary to the analog signal which is influenced by the deformation of video signal and the distance of transmit, it is possible to transmit the video signal without limitation of distance and deformation of signal through Equalization and Recloking of the video signal at intervals.

 

What are the benefits of using HD-SDI?

  • Up to 1080p resolution
  • Works over existing coax cable
  • Simple plug & pay
  • No networking
  • Upgrade existing analogue installations
  • Horizontal Resolution 1000 TV Lines
  • Day & Night Function
  • WDR(Wide Dynamic Range)
  • BNC connector to run your cable
  • RG-59 cable
