Product Description
The RJ45 balun 8MP (SKU RJ45-balun-HDPV-8MP) is a small adapter that carries a CCTV camera's video and power over twisted-pair cable, the paired-wire type used for network cabling, and gives you an RJ45 plug at the end. It is identified as an 8MP model, so it is aimed at high-resolution cameras.
Where it fits
- A new camera run where you want a tidy RJ45 connection point.
- An existing twisted-pair cable you want to reuse instead of pulling new cable, as long as it is compatible with the camera and recorder at each end.
Four checks before you buy
- Video format: make sure the formats your camera and recorder use are supported by this balun.
- Cable: check the cable requirements against what is already in the wall or loft.
- Distance: measure the run from camera to recorder and compare it with the balun's transmission distance.
- Power rating: check it suits your camera's power needs.
Why the power check matters at night
Infrared LEDs, which light the scene after dark, draw more power than the camera does in daylight. A weak supply or a long cable can cause voltage drop (power fading along the wire). The result is often a flickering or black picture at night, even though the camera looked fine by day.
