This video demonstrates how to install active video baluns with Cat5 cable for CCTV video transmission. The AVB1 active balun system will be used in this demonstration.
On the left we have the transmitter side of the balun system. A single twisted pair from a Cat-5 is already connected to the terminal block of the device.
The terminal block conveniently detaches from the transmitter allowing the installer to attach the cable more easily. In addition to the two connections used for video, there is a third connection for grounding the device.
When the ground terminal is properly grounded, the balun also provides lightning and power surge protection. A DC power supply is included and connects as seen here.
A short BNC jumper cable is used to connect the CCTV camera to the input of the trasmitting balun.
A distance selecter is located on both the transmitter and receiver baluns that allows the installer to adjust the amplification based on the distance of the cable run.
The receiver balun is connected on other end of the CAT-5 cable using the same style screw down terminal block.
The reciever unit has the 3 distance level settings as well as a gain control to fine tune the video picture output.
A BNC cable is attached to the reciever balun, which can then be connected to a surveillance DVR or BNC monitor.
The receiver balun is also powered which enables the CAT-5 cable to be run up to 5000 feet.
So, in review, a CCTV camera is connected via BNC coax cable to the transmitting balun.
The transmitter is connected to the receiver using a single twisted cable pair from CAT5 cable.
And the receiver has a BNC video output that can be connected to a DVR or
