HD TVI Video Recorders

HD-TVI (High Definition Transport Video Interface) is a new and improved technology where a digital signal converted then transmitted over coaxial cable much like CCTV signals.  HD-TVI technology was developed in 2012 by Techpoint, a U.S. based firm).  It allows for higher resolution (720p and 1080p) cameras to be recorded over traditional coax infrastructure.  TVI is an open-architecture technology allowing it to be used by many manufacturers and can be used in an environment with cameras from multiple manufacturers.  HD-TVI is also much more cost effective than HD-SDI technology.  HD-TVI Video Recorders receive the signal and convert it back to a digital format for recording and live viewing.
