Description
Product 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

Weight-107g/pc
• 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
• DC loop resistance: 18Ω/100m
• Differential capacitance: 62pf/m (maximum)
Connection method:
• Connect the two-colour wires of a pair of Cat-5 unshielded twisted pair wire to the ‘+’ terminal of the yellow socket and connect the single-color wires to the ‘-’ terminal of the green socket.
• Connect the BNC interface of the transmitter to the BNC interface of the camera. If there is any joint in the circuit, please adopt welding method or special junction box to ensure perfect contact at the joint.
Adjusting method:
• Adjust and slide the switch according to the distance
