Here is another one of those clocks that come with an integrated spy camera in them. The Tiny Spy Camcorder clock can be used to check on the kids or see if your nanny or household help is truly sincere in her job and is not doing anything else. It runs on a built-in rechargeable battery that is good for 2 hours of use. For storage, it comes with a 4G built-in memory but you can also use a separate USB drive through the cable provided with the package. The Tiny Spy Camcorder Clock can be bought at Gadget Brando for $47.
