AHD/CVI/TVI/CVBS Video and Power multiplexer Over Coaxial, Video and Power Extender Transmitter Using coaxial Cable Transmit coaxial Signal + Power at The Same time Over 400 Meters (1300ft)

I had and old model rear view camera and monitor in my motorhome. It used a single coaxial cable to send power from the monitor to the camera and the video from the camera to the monitor. The devices units require separate power for the monitor and camera. Instead of stringing new power wire for the camera, I used these units. I installed one unit in the cabin and connected the power wires to the ignition switch and the video to the monitor. I installed the other unit behind the camera and connected the video cable and power to the camera. Now the camera comes on at the same time as the monitor. Be careful to match the connectors as some video equipment does not use BNC connectors as supplied on these devices. I had to replace one of the connectors because my two cable ends were different.

FIrst off want to say that this worked good for me in that it allowed me to get video to a place where I had a coax cable run, but no power option available. It does a good job of getting the power out to the camera and the video returning to the DVR. However, there are 2 drawbacks - 1. The quality of the video to me isn't quite as sharp as my other cameras that aren't having the adapters. 2. This is probably the biggest drawback for me - it doesn't support the PIR on my camears. The option doesn't show up in my DVR when plugged in through these adapters. The camears I have direct connect and with a cat5 adapter work just fine with PIR. Other than those 2 things - it works like it should.

I suspect the HD-PVT works great. However, both transmitter and receiver have a tag on them stating the following: “Power in: DC24v-36v Out: 12v/1A.”If one applies 24v DC to the transmitter module, the 1000 mfd 16v capacitor inside will explode in your hand with pieces flying everywhere, knocking the glasses off your face and scaring the crap out of you.Caution! Apply 24v ONLY to the “receive” module. Tear the tag with the statement “Power in: DC24v-36v Out: 12v/1A” off of the transmit module and throw it into the trash. Do this, and the unit will most like work just fine. I may give it another try later.

We're a professional installer, and we ran into a situation where the pervious installation (not ours) had been done with the power being sources locally, and only the coaxial cable was home run. During a renovation, the local power was cut, and the affected cameras were in a critical location. We tried running alternate wires, but that proved impossible due to structural factors. These units saved the day.

this solved the problem I had with coax and no power but I had to buy the power adapter and once connected my 5mp camera only worked in black and white. Returning the product.

This work great in using it from existing builder installed single coax cable (power over cable) line to a new camera that had separate power and data cables.

Need to provide power over COAX, this worked great.
