When the PIR (Passive Infrared) Sensor detects moving heat from car engines or human beings, the transmitter will activate and send a wireless signal to the Receiver. The Receiver plays a configurable alarming sound.
A powerful 120-decibel alarm sounds as soon as motion is detected within a 20-foot range. Unique security code between chime and sensor - avoids interference with neighbour's chimes. Blue LED Light, volume adjustment (upto 3 levels) and including 36 Melodies to choose from.
Easy to install and requires no wiring, battery operated chime unit can be free standing, you can take it anywhere. Operating range of over 300 feet (between sensor and main chime unit).
Can be used as a simple alert unit instead of investing in costly security systems! Detecting and alerting when someone approaches a front door! Alert when a customer walks through the front door of a store or office! Alerting when a car approaches a driveway, and many more!
Note: Includes 1 plug-in receiver unit and 1 battery powered motion sensors. It perfectly combines the function of driveway alert with a doorbell. Any item from 1byone with the "Easy Chime" Logo can be combined. If you need additional sensor, we suggest O00QH-0513.
