This is actually a pretty smart idea. This camera from Hammacher Sclemmer is really just lollipops, rainbows and smiles on the inside. It is completely fake and even includes a blinking red light powered by a AA battery to really convince the criminals that they are being recorded. But wait! It gets worse! You receive two of these faux cameras for a blistering $60. For that much you can setup your own, real security system with a low-end web-cam hooked up to a PC. Or if you are really cheap—just do what I do and put up a fake sticker: "Monitored by Such&Such."
