Sometimes even our own homes might not be as safe as we want them to be. Wireless security camera systems can help ensure safety by providing constant surveillance of homes, or even businesses. Wireless security camera systems can be used both inside and outside a house. Some families have wireless security camera systems installed in children's bedrooms or playrooms, not to stop burglars, but to monitor children from another room. But more commonly, wireless security camera systems are used to prevent crime and apprehend criminals. Many criminals are deterred at the sight of security cameras, while those who do commit crimes will be caught on tape, making them easier to identify.

Wireless security camera systems operate with two main devices: the camera and the receiver. Wireless security cameras are usually mounted on walls or ceilings and are not hard-wired to the system, though many require wires to be connected to a power source. They are available in black and white or color, and many can be modified with different lenses to improve field of view, range, or resolution. Some wireless security cameras are also equipped with infrared night vision, although night vision cameras generally have much shorter ranges. These cameras transmit video signals back to the receiver, which can be kept anywhere within a certain radius of the cameras.

Receivers can handle more than one wireless camera at once. Wireless security camera systems use the receiver to either display the video feed on a TV or computer, or to save the information on a storage device, such as a DVR.
