The VB351R 1ch active UTP video receiver receives balanced signal
to converts it into unbalanced signal and raises the received
signal with perfect receiving effect, which can be applied in the
occasions such as video monitoring and video meeting. It can
simplify the wiring project and save wire use quantity.
- Adopt differential signal transmission with excellent anti-jamming
- 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 will be 1500m if it is used with
passive transceiver and the farthest transmission distance can
reach 2400m if it is used with active transmitter
- Outstanding interference rejection, transient protection

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)
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. 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!
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
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.
