Use
CJ-804M is to convert the video signal into the balanced signal applicable to be transmitted on common Cat-5unshielded 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.
Other
Type of the required wire:
Unshielded Cat-5 or above twisted pair wire (Please use standard Cat-5 or above
twisted pair wire. The wire quality will directly affect the transmitted image effect and
transmission distance.)
Characteristic impedance: 100Ω±20Ω
