What is HD-CVI
HD-CVI stands for High Definition Composite Video Interface. This is a brand new technology in the security camera industry that provides a different method of transmitting video signals over coaxial cables. Until this new technology surfaced, analog CCTV video was limited to 960h video resolution. 960h resolution refers to the 30% increase in horizontal resolution, so the maximum analog resolution up to this point was 960 x 480 pixels. This has been the accepted limit to analog video transmission for many years. In order to achieve greater transmission would mean switching to digital video using either HD-SDI (High Definition Serial Digital Interface) or Network IP video formats.

Enter HD-CVI, a true alternative to Network IP solutions. HD-CVI uses a licensed video transmitter and receiver that is able to transmit up to 1080p video resolution (1920 x 1080) in an uncompressed format over the same standard coaxial cable that is used for standard CCTV cameras. This uncompressed video format is able to transmit over longer distances than either HD-SDI or Network IP cameras and without the latency and bandwidth issues that are so common. Additionally, HD-CVI is able to transmit video, audio and control (OSD or PTZ) over a single coaxial cable instead of requiring separate cables for each transmission.

What is really separating this technology from the rest of the options for video transmission is the cost effectiveness of HD-CVI. In most cases HD-CVI is around the same price as the older analog CCTV technology and is far less expensive than HD-SDI or IP Network transmission.

When comparing HD-CVI to Analog CCTV cameras:

  • CCTV cameras are limited to 960h resolution which is 960 x 480 pixels. HD-CVI cameras can transmit up to 1080p resolution (2 Megapixel) which is 1920 x 1080 pixels. HD-CVI is capable of up to 450% great resolution and detail than standard CCTV cameras and DVRs.
  • CCTV can only transmit video over the single coaxial cable. Audio and control must be run over separate cables. HD-CVI can transmit video, audio and control over a single cable saving money and time.
  • The price point of analog CCTV and HD-CVI is about the same. You get more resolution for the money with HD-CVI.
