*How does it work:Basically,there are two parts to the PIR Motion Doorbell:Transmitter and Receiver.The Transmitter contains a passive infrared (PIR) sensor,which detects the moving heat created by an automobile's engine or any other noticeably hot object moving at sufficient speed,like human beings.It can send signal to the Receiver.The Transmitter should be mounted close to door for detecting any visitor,or mounted at places that have a clear view of the driveway for detecting cars.The Receiver mounts inside your home,or business,warehouse within effective range of the Transmitter.It is with LED indicator and chimes to let you know when the Transmitter detects motions
