Hidden Cameras

Hidden video cameras, also known as "nanny cams" or "spy cams", are tiny cameras designed to be concealed in almost any conceivable item, from a shirt button to a houseplant. Since the advent of 911, this type of camera has become a security and monitoring tool used in many public places like airports, railway terminals, shopping malls, or any other public place where monitoring the activity of people is important to security and crime prevention.

Hidden cameras also provide a means for homeowners to observe activity around their home without the camera being visible. These cameras are useful in keeping an "eye" on the nanny or babysitter when parents leave the care of their children to these individuals. Recently developed remote monitors make it possible to observe activity in side your house while you are away. For example, a homeowner can monitor activity from the office or any other location with Internet access. When connected to a recorder, hidden cameras can record that activity.

Hidden cameras are produced in wired and wireless designs. Wireless cameras require batteries to operate. Wired devices require hardwiring to a power source. The advantage of wireless systems is obvious. Wireless systems continue to operate even in the event of a power failure.
