Securnix Single Channel Active Video Balun, , 1 Year Warranty
75 Ohm to 100 Ohm Active Video Balun for CCTV , Rj45 Video Balun, VB120TProduct Overview
The Securnix VB120T 75 Ohm to 100 Ohm Active Video Balun for CCTV , Rj45 Video Balun, active UTP video transmitter is to convert the video signal into the balanced signal applicable to be transmitted on common Cat-5 unshielded twisted pair wire with perfect transmission effect, which can be applied in the occasions such as video monitoring and video meeting and can transmit four channels of video image simultaneously on an 8-core Cat-5 twisted pair wire. It can simplify the wiring project and save wire use quantity.
Features:
Adopt differential signal transmission with excellent anti-jamming ability
Save project wire expenses, each a pair of twisted pair wire transmits one channel of video signal and one common Cat-5 unshielded twisted pair wire can simultaneously transmit four channels of video signal
The farthest transmission distance can reach 2400m if it is used with active receiver
Outstanding interference rejection, transient protection
