Most wireless security cameras include at least one antenna or cable television for electric power; however , “wireless” indicates the transmission of audio/video. These kind of cameras may be set up in virtually any location meant for monitoring security, both in house and exterior. A few wireless video cameras can also incorporate a built-in camera to produce high quality images of individuals and actions on the monitoring area. Wifi security cameras transmit their impulses through a transmitter or receiver that is placed in a location that will receive the signal and is generally found in close proximity to the area to get covered.

Some security cameras transmit their indicators in the visible light portion of the electromagnetic spectrum, and some transmit inside the ultraviolet percentage of the electromagnetic spectrum. A few cameras have an internal purple eye, as well as other visual effects, so that they can be used like a night eyesight surveillance system.
