Check with you salesmen for any special new kits. Another home use for cameras is to see who is at you front door. You can go off and spend a couple hundred dollars on a commercial camera system or build your own real cheaply. This idea uses your existing door bell wiring. A wired camera transmitter and receiving system can be made for a couple of bucks, using only a handful of components at each end.
Assembly is simple and can be done in a couple of hours.
Video is passed down the existing wiring using a transmitting circuit that breaks the video into 2 identical sources traveling down the parallel wires. At the other end the same circuit wired slightly different is used to put the signal back together and remove and noise that was picked up. The receiver, board, PS and monitor can be placed where you current doorbell rings and provides a convenient place to view strangers. The circuit is based on a couple Nationals Semiconductor op amps, the LM6181. These amps have the bandwidth to easily handle composite video and the ability to reject noise in the video range.
