A hidden camera is an unmoving or video camera used to film people exclusive of their acquaintance. The camera is "hidden" for the reason that it is either not noticeable to the people being filmed, or is cloaked as another object. Hidden cameras have become admired for household surveillance, and can be built into familiar 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 is either wired or wireless. The former will be attached to a TV, VCR, or DVR, whereas a wireless hidden camera can be used to broadcast a video signal to a receiver within a little radius (up to a few hundred feet).

For mobile-covert surveillance, hidden cameras can even be masquerading as clothing such as a necktie, ball cap or even a button on your shirt. Miniature DVD recorders that are small enough to fit in your pocket can record the whole thing the hidden camera sees for later screening, or with a wireless receiver, you can broadcast the video to a remote position where somebody else can be screening and recording in existent time.

Hidden cameras may also be used commercially as security cameras. There are various different uses for hidden security cameras. Conventionally they were used largely for commercial or industrial applications to keep an eye on employees, building perimeters, warehouse storage area, etc. They have though become progressively more admired for home surveillance. Homeowners are using them to keep attentive eye over their child's caregiver, to monitor sleeping children, and even to watch over their teen while they are home alone. Homeowners are also installing hidden cameras outside their homes to take care of the exterior of their property, their vehicles, etc.
