Description
A hidden spy camera can be wired or wireless. The former will be connected to a TV, VCR, or digital video recorder (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). Consequent to the wide proliferation and lower costs of electronics devices, hidden cameras are increasingly finding wider applications.
