Product Description
1CH Active UTP  Video Balun for CCTV Cameras (VB300T)
 

Description:
The Active Transmission UPT CCTV Video Balun VB300T 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:
1.      Adopt differential signal transmission with excellent anti-jamming ability
2.      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
3.      The farthest transmission distance can reach 1200m if it is used with active receiver
4.      Outstanding interference rejection, transient protection
5.      Third gear gain amplification adjustment
6.      "Press-Fit" terminal block
7.      ABS plastic case

Adjust and slide the switch according to the distance.

 
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.
