I am considering buying a multi-camera CCTV kit for the home, but I can not find a good way connect the DC power.
The idea is to run the cables through the attic and down into the stud bay to a common double gang box in the room where the DVR would be. The wall plate would be a Quick Port just like I used to for surround sound connections. Quick Port has BNC snap in connector (http://www.levitonproducts.com/catalog/model_40832.htm) , but they have nothing for the 12V DC.
I have been thinking I could buy cable extension adaptors and drill a hole in blank snap in plates, but I don't know where to buy the adators or what size is the DC plugs should be.
Some one has got to have delt with this issue and hopefully has a good solution.
