Why use
video baluns? Typically coaxial cable is used to carry video
between the camera, dvr or monitor. Substituting networking cable (Cat5e a.k.a. twisted pair)
will allow for
longer runs at an overall cost savings since CAT5e cable costs
considerable less. By using video baluns, longer runs of up to 5,000
feet or more are achievable.
How do I use CAT5e to run baluns? CAT5e cable consists of 8 wires or 4 pair.
Because video is sent in pairs,
one CAT5e cable can support up to 4 cameras. If fewer cameras are needed,
the wires can be used to carry power, so that cameras can be powered
from far away and use a single run for multiple cameras.
The CCTV Balun works in pairs. Plug one CCTV Balun into the coaxial connector of the CCTV camera and plug a second CCTV Balun into the coax connector of the CCTV monitoring equipment (i.e.; DVR, mux, IP camera server, monitor) at the other end.
See diagram below of how an example if running 4 cameras to one zone using one CAT5e cable with 4 pair of video baluns from cameras to the back of the DVR.
