The motion sensor itself is an infrared sensor. In fact, the name of the sensor is a Passive InfraRed or PIR detector. It works by constantly monitoring the infrared radiation (IR) in the cameras general field of view. When a sudden change in this radiation occurs, the sensor can detect it, and assumes it is caused by an object in motion. The PIR motion sensor is connected to a relay switch so that when motion is connected, the relay switch turns on the camera to being recording. The recording session ends when either the motion has stopped or after a pre-programmed period of time after the motion has stopped.

If you don't want to install a coaxial video transmission cable from each camera to your Digital Video Recorder (DVR) or personal computer wireless home security internet cameras may be the perfect answer for you. Recent advances in computer and electronics technology have made these cameras easy to use and economically priced so that they are affordable for just about any budget.
Digital video security cameras normally use an RG-59 coaxial cable to transmit their video signal. Each camera must have a cable run to the Digital Video Recorder or DVR. If this cabling is impractical for your business or office, or you need cameras placed fairly large distances from the DVR (such as industrial settings) then business wireless security camera packages could be your practical solution.
Wireless 16 camera motion detector security systems are the ultimate solution for digital video camera surveillance and security. The wireless cameras not only provide quick and easy installation, but can be installed just about anywhere. In addition, the motion detection feature provides for conservative storage needs on Digital Video Recorders (DVRs) and if used with the Tilt-Pan-Zoom (PTZ) function can be used to track objects or individuals throughout a camera’s useful field of view.
