Transmission par paire torsadée

Twisted pair transmission

The baluns and transceivers on this page are used to carry an HD analogue video signal over twisted pair cable rather than over coaxial. This is the usual route when a building is already wired in UTP, or when coaxial cable is awkward to run. The selection covers passive and active models, with one or more channels, some of which also carry the camera's power supply, under the Dahua, Airspace, CCTV Direct and VESTA brands.

The choice comes down to the video format: each product states what it supports, HDCVI, HDTVI, AHD or CVBS, and the associated resolution. Match that format to that of your cameras and your recorder, count the number of channels to be connected and remember that a balun is installed in pairs, with one module at each end of the link.
