HD Analog Cameras
HD-TVI stands for High Definition Transport Video Interface. It is a digital signal processing and transport technology used to transmit video in HD security camera and DVR.
HD- TVI currently supports resolutions 3 megapixel and 5 megapixel using the coax cable. This allows for people with existing analog cameras to upgrade to a HD system using their existing cable. Also, it is a more affordable solution for home owners compared to IP cameras.
