I purchased this unit to add to the wireless camera system that I had bought locally. This is the secondary camera for the Wireless Color Camera with Receiver 45234 ([...]). First of all, the price was the lowest that I had found. Shipping was FAST. Unit came well packed and in perfect condition. Easy to hook up. Just mount it in your desired location, plug it in, and set the viedo input selector on the receiver. Mine is connected to a tv and vcr player/recorder. Camera image is identical to the original one in the wireless camera system. If you plan to use this unit at night, do not mount it in a window, as the night vision lights will only reflect back into the camera. Therefore, either use it for interior purposes, or mount it in a sheltered location outside. Mine is mounted over the entry door on a covered porch, so there's no weather exposure issues. If you need an extension for the 8' power cord, the distributor ([...]) can sell you a 15' extension cable for the camera. You might need the product number to research this: Wireless Color Camera 45233. They also carry a battery pack that they say lasts up to 5 hrs. I'm very happy with my purchase.
