1001 Hidden Camera

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).

A small board camera is built into an everyday hidden camera. The camera can be wired which means it is connected to the DVR or VCR using a cable. The camera can also be wireless, in this case the camera transmits a signal to a receiver that is connected to the DVR or VCR.

Board Cameras are basically a fixed lens mounted on a circuit board. These cameras are often used in mini cameras, dome cameras and for making hidden cameras but are also sold unpackaged, for mounting by the buyer.

Lenses in these cameras are either of a full opened lens or pinhole in which the opening of the lens is very small. Pinhole lens cameras are often called spy cameras and are most often used in making a hidden camera.
