I would like to install four security cameras around the outside of my house, but I have some questions before I start buying equipment...
1) The cameras I looked at, all have 60' cables attached to them. I would have thought that the camera would have a 'stub' cable of 12 inches or so, and then a 60' extension....that way, if a camera fails, you can just switch out the camera itself without having to remove the entire run of cable and the RE-install the cable in addition to replacing the camera. Is this not how it's done? Are there cameras available with only a stub of a cable attached?2) The 'far' end of the cables have two plugs in them: one (a BNC I think) for signal and the other for DC power supply. I know that all four of the signal plugs will plug into the DVR card in my computer, but how do I manage the four power-supply plugs? Is there some way to power all of the cameras without taking up four spaces in my power strip? Do some DVR cards have a 12V power jack next to each signal jack? I'm just trying to keep the cabling clean.
3) When looking at the completely installed camera, should I just see a cable leading from the camera into a hole in the wall, or does someone sell a wall-plate with a BNC connector and a DC power-supply jack, which would be mounted on the wall near the camera, and to which the camera is connected?Any advice you can offer would be greatly appreciated!
