How does it work?
Basically, there are three parts to the Driveway Alert system.
1. The Indoor Alarm Receiver works as an alarm buzzer and a doorchime. It monitors for signals coming from the Passive Infrared (PIR) Motion Sensors and the Doorbell, and activates an alert in response to that signal. It also features a series of LED indicators on the front of the unit so you can visually tell where an alert is coming from. The Indoor Alarm Receiver can be either mounted to a fixed location or completely free standing.

2. The PIR Motion Sensors enable you to monitor for movement in two zones or areas surrounding your property. Each contains a miniature radio transmitter, which sends a signal to the Indoor Alarm Receiver whenever motion is detected. The motion sensors should be deployed outdoors, where there is a clear view of the driveway or the likely entry and exit paths that you plan to secure.

3. The Doorbell enables visitors to send a chime to the Indoor Alarm Receiver so you know that someone’s waiting at your doorstep. As it is neither water nor weatherproof, it must be installed in a sheltered location.
