WHAT IS HD-TVI?
HD-TVI, or High Definition Transport Video Interface, is a technology that converts digital signals to analog signals. This technology allows systems to achieve high definition video quality over coaxial cabling. HD-TVI is backwards compatible with analog cameras and can support up to 960H analog cameras and up to 1080p HD-TVI cameras.
A manufacturer partnered a California based company that specializes in the design of integrated circuits for high definition video to develop the HD-TVI technology. HD-TVI is an open platform technology, giving manufacturers the technology necessary to produce their own HD-TVI product lines. Even with the introduction of other technologies,
HD-TVI has attracted over 100 manufacturers to design and distribute their own HD-TVI product lines. With so many manufacturers adopting the HD-TVI technology, wide varieties of camera housings are available to choose from along with additional features, such as remote focus and remote zoom lens control.
