[QUOTE="SweetSVT99, post: 15712969, member: 15"] With wired cameras, you have two types: Analog, which is typically connected via a BNC connector for signal and a barrel connector (think of an AC Adapter type connection) that normally carries 12v. You can get these two cables molded together pre-made in all kinds of lengths. The power supply will be back at the DVR side of your cable, and can either be a simple AC Adapter or in larger installs they'll be a box containing a block and a power supply. The second type of wired cameras will be IP Cameras. These generally are PoE (Power over Ethernet) and use a simple Cat5/6 cable and an RJ45 connector just like any other networked device. The power will be carried through the Cat5/6 cable using either the switch or a pass through PoE injector. Wireless cameras can either be battery powered or will need a power source (usually 110/120v, stepping down to 5 or 12v with an AC Adapter of course) nearby. I have no experience with wireless cameras and no desire to try any of them. I don't want my security cameras to rely on WiFi and a battery, and if I have to run wire for power anyway - I might as well just run some Cat6 and call it a day. [/QUOTE]
