Review on 🔌 Coaxial Video and Power Multiplexer: AHD/CVI/TVI/CVBS Signal Extender, Transmitting Over 400 Meters (1300ft) by Brian Kingsford

First let me say that this worked for me in that it allowed me to get video in a place where I had coax but no power. It does a good job of powering the camera and returning video to the DVR. However, there are 2 downsides - 1. The video quality for me is not as sharp as my other cameras that don't have adapters. 2. This is probably the biggest disadvantage for me - PIR is not supported by my cameras. This option does not appear on my DVR when connected through these adapters. The cameras I have with direct connection and with a Cat5 adapter work well with PIR. Other than those two things, it works as it should.
