Video Surveillance

HD-TVI brings high definition image quality over a single coax cable at a more cost-effective price. This exciting new technology is sure to become the new standard in the CCTV industry.

What is HD-TVI?

HD-TVI stands for High Definition Transport 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, customers would have to switch to digital video using either HD-SDI or Network IP video formats.

HD-TVI 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 both HD-SDI and Network IP cameras and without the common bandwidth and/or latency issue. Additionally, HD-TVI is able to transmit video, audio and control (OSD or PTZ) over a single coaxial cable instead of requiring separate cables for each transmission.

The Benefits

What really separates this technology from the other options is the cost effectiveness of HD-TVI. In most cases, HD-TVI is around the same price as the older analog CCTV technology and is far less expensive than HD-SDI or IP Network transmission.

If you are looking into upgrading an existing CCTV camera system to megapixel quality video, HD-TVI should be at the top of your list of considerations. By simply replacing the existing analog cameras and the DVR with our cost effective HD-TVI cameras and DVR, you will instantly upgrade your system to megapixel quality video producing an increase of up to 450% in resolution! There should be no need to replace the existing cable infrastructure, which is usually the most expensive portion of the installation.

If you are considering a new security camera system, we highly recommend our HD-TVI systems. It will cost around the same as the analog systems and can provide you with the same resolution as most IP Network camera systems and without the bandwidth and latency issues.
