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. Connect the BNC interface of the receiver to the monitor or other recording equipments. 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 “BRIGHTNESS” knob to adjust the image brightness, then adjust “SHARPNESS” dial switch to compensate the image sharpness and color. The compensation size in turn is 1 as minimum and 4 as maximum. Pressing dial switch shows the compensation of this position is turned on. Next or multiple switches can be pressed according to the requirements. The four dial switches can compose 16 compensation values (as shown in the following figure) to meet the requirements of different transmission distances.
Frequently Asked Questions:
Why does my video look like a scrambled Cable TV signal?
This typically indicates reversed polarity.
Can shielded twisted pair be used?
Some customers have successfully used shielded wire up to a few hundred feet. However we does not recommend it. Its high-frequency roll-off will severely degrade the distance performance.
Can Category 6 wire be used?
Yes. Unshielded Twisted Pair wire, Category 5 or better, can be used with UTP video transceiver.
Can I transmit more than one video signal in a multi-pair wire bundle?
Yes. One of the benefits of using UTP video transceivers is interference rejection. UTP video signals can reside in the same wire bundle as multiple video signals, ringing telephones, Ethernet, low voltage power, RS-422, RS-485, etc.
