I am a newbie to security cameras and have a very basic question. How do you get power to the cameras? I have a floodlight connected to an exterior junction box that I would like to replace with an RLC-422W. After I remove the floodlight, I have a junction box with 110V house wiring. How do I connect the power supply? Ideally, the camera had a power supply internally that I could just use wire nuts to connect it to the house wiring, but I don't see how to connect to the power supply. The only way I see to do it is to drill a hole through the wall, run the wires to the interior and plug the power supply to an electrical socket which would look terrible with three wires with connectors to another wire down to the power supply near the floor. Suggestions?
