16 Channel Active Video Receiver with Spring Joins Terminal VB1610JR

16 Channel Active Video Balun / Video Receiver with Spring Joins Terminal VB1610JR

Description:
The VB1610JR active video receiver receives balanced signal to converts it into unbalanced signal and raises the received signal with perfect receiving effect, which can be applied for the occasions such as video monitoring and video meeting and can transmit four channels of video image simultaneously via a 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 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

Technical 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:
Clamp the modular plug for a Cat-5 unshielded twisted pair wire according to the connection order of TIA/EIA-568B (please refer to the following figure) and connect the clamped modular plugs to the RJ45 socket .If there is any joint in the circuit, please adopt welding method or special junction box to ensure perfect contact at the joint. Connect the BNC interface of the receiver to the monitor or other recording equipments.

The clamping order of the modular plug is shown as follows (TIA/EIA-568B):


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 do 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.
