Components of a Wireless Security Camera
A wireless security camera relies on communication between video transmitters and receivers. Most new digital-video cameras come with a built-in wireless feature that allows the cameras to connect to a computer or the device being used to receive the signal. The receiver must also maintain a wireless connection to a monitor or time-lapse recorder in order for the wireless security camera to capture the feed going into the receiver.
Wireless Security Camera Frequencies
The communication between camera and receiver takes place at a frequency specific to both devices. Most wireless devices, cameras in this case, allow you to select from only four frequencies.
