A hidden camera is a still or video camera used to capture video footage of people without their knowledge or consent. The camera is considered to be “hidden” because it is either not visible to the subject being filmed, or it is disguised as another object. Hidden cameras have become popular for conducting household surveillance. Hidden cameras 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 to catch thieves and even dishonest employees.
Wired or Wireless?
A hidden camera can be wired or wireless. A wired hidden camera will be connected to an electrical outlet and a television, Video Cassette Recorder (VCR), or Digital Video Recorder (DVR). 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).
Some hidden camera footage has led to lawsuits or being denied to air by the people who were trapped in set-ups that they found unpleasant. Hulk Hogan was recently involved in a lawsuit with Gawker, who released hidden video footage of the star having sex.
