Can you use Powerline adapter to transmit CCTV camera signal

[james121515 0]

I am sure this topic has been brought up but googling has not yielded a clear answer.

 

I have an SDE3003 which uses CAT5 cables to power the cameras as well as transmit the video signal to the DVR. I just bought a NetGear PowerLine adapter so I could avoid having to run the CAT5 cables through the attic and walls, but unfortunately, this does not work. The cameras only work if connected directly into the RJ45 jacks on the DVR with a CAT5 cable. I thought maybe our electrical wiring doesn't support this, but I tested the Powerline adapters with a computer and modem and am able to access the internet over our power system, so I know the adapters work. Is it just not possible to do this with CAT5 security cameras?

Absolutely possible

Any idea why it isn't working?

Powerline networking adapters transmit/receive ethernet data signals. They don't work with analogue video signals or any other type of data, regardless of whether it happens to be on a RJ45-style jack or not.

 

The data signals on the Samsung DVR are

 

1 CVBS+

2 CVBS-

3 AUDIO

4 GND

5 12V

 

not compatible with ethernet

 

You could probably extend the DVR 'network' port over Powerline if you wanted to.

Thank you for taking the time to write a thorough response to my question.

 

So is it pretty much impossible to use my home's existing power wiring to run a video signal, even with the higher end "Powerline" adapters? I wish there was something I could do as running wires through my home is a nightmare as every wall has very thick horizontal studs (fireblocks) about 3 feet above the ground.

 

Is it somehow possible to use my home's existing coaxial cabling? We have not one but two coax cables running to every room in our home, which would definitely make our lives easier, if it's at all even possible.

Hi. Yes it is possible to us your existing coax .... Each of your existing coax can run 4 analog cameras.

 

 

Analog over power line can also be done but it is very expensive 5x the cost of eithernet power line. (And you need one for each camera)

 

 

How many cameras are you looking to install

There may be analogue-video-over-mains adapters available but they'd probably be for professional use and Not Cheap.

 

You could run video over coax and use local power supplies for each camera, use one of the coax cables for video and one for power, or use a video+power over coax product.

Looking to install four cameras: two indoor two outdoor. I plan to return this SDE unit anyway as the night vision quality is awful compared to my other Samsung SDR unit at my business, which uses BNC. I would like to get something similar to what I have at work since I am familiar with the Samsung software and I know that the other unit at works flawlessly.

 

It's my understanding that BNC is essentially coax. Since there is coax running all over my house, If I got a unit that utilizes BNC, could I somehow use this to my advantage? In particular, I want to put a camera right outside the window of a room that already has coax running to a wall plate that is right by the window. The only thing is that that coax is already being used for a television. If I can't somehow split the coax to be used for both?

 

I apologize I am new to this. I might be getting in over my head and should consult a specialist.
