A hidden camera can be wired or wireless. The former will be connected by cable to a viewing or recording device, such as a TV, VCR, network video recorder (NVR), digital video recorder (DVR), memory card or other data storage medium; whereas a wireless hidden camera can transmit a video signal to a receiver within a small radius, where the images may be viewed or recorded. Hidden cameras may also have an audio capability. A hidden camera may be activated manually, by remote control or be connected to a motion detector.
