The camera is "hidden" because it is either not visible to the subject being filmed, or is disguised as another object. Hidden cameras have become popular for household surveillance, and can be built into common household objects such as smoke detectors, clock radios, motion detectors, ball caps, plants, and cell phones. Hidden cameras may also be used commercially or industrially as security cameras. A hidden camera can be wired or wireless. The former will be connected to a TV, VCR, or DVR, whereas a wireless hidden camera can be used to transmit a video signal to a receiver within a small radius (up to a few hundred feet). 22*12.2*4.6cm 0.655kg
