Description:
The VB411T 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 protectionTechnical specifications:

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
DC loop resistance: 18Ω/100m
Differential capacitance: 62pf/m (maximum)
Connection method:
Connect the two-color wires of a pair of Cat-5 unshielded twisted pair wire to the ‘+’ terminal of the green 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. Please be sure to connect the interface marked with ‘’ symbol to the ground wire of the lighting-proof system with the copper conductor with sectional area≥1.5 mm2!
The clamping order of the modular plug is shown as follows (TIA/EIA-568B):
Adjusting method:
Adjust and slide the switch according to the distance. The switch can be slid to the lowest level when the distance is between 1400m and 1700m, the switch can be slid to the middle level when the distance is between 1700m and 2000m and the switch can be slid to the highest level when the distance is more than 2000m (as shown in following figure).
