These spy cameras are built into regular household objects and are used to monitor what’s happening when you are away. For example, if you are nervous leaving your kids with a babysitter, a covert spy camera will let you keep an eye on them. SpyTown has covert cameras and spy gear built into teddy bears, alarm clocks and smoke detectors, to name a few. Please note that covert cameras do not include any audio capabilities, as it is illegal to do so in most American states and Canada.
