Just when you thought your home is your castle, along comes another device like the Oral B spy toothbrush to turn you into a paranoid android. The recorded video even comes with a date stamp for records purposes, giving you a real look at what people normally do in the bathroom while bringing the voyeurism level up by another notch. You will need to fork out $243 for this though, where all your video will be stored in AVI format at 640 x 480 resolution. At least you can tell who is the culprit behind toilet seats that are never closed after being used.
