TWIST-P1F AND TWIST-P1M UTP PASSIVE VIDEO TRANSCEIVERS

 

Video transceivers TWIST-P1F (female BNC) and TWIST-P1M (male BNC) are based on a balance-to-unbalanced transformer (video balun).


When installed on the transmitting end of the video line, the TWIST-P1 series balun converts a signal from the source (video camera) into a differential video signal.


When installed on the receiving end of the video line, the TWIST-P1 series balun converts a differential video signal into a standard single-ended one.

TWIST-P1 series transceiver transmits quality colour and B&W video signals up to 300m using unshielded twisted pair (UTP) cable when used in combination with another passive transceiver TWIST-P1F or TWIST-P1M.

 

TWIST-P1 series transceiver transmits quality colour and B&W video signals up to 300m using unshielded twisted pair (UTP) cable when used in combination with another passive transceiver TWIST-P1F or TWIST-P1M.

 

TWIST-P1 series transceiver also comes as 16 way unit on 19’’ 1U rack, it’s called TWIST-P-1URM16.
