Now you can watch easily how your babysitter makes her/his work. With a Hidden Camera Spy Clock it can be done very effective. It comes with a full color camera that transmits signals to a remote receiver for real-time recording. The price of the Hidden Camera Spy Clock is $64.00 which is good for this kind of gadgets. But personally, I’d prefer IP cameras. They are much handy and power. And possibly the babysitter should know about supervision.
