Product description
The driveway alarm provides a solution to alert you the moment someone enters your property. It's not only very convenient but also extremely affordable.
When movement is detected, the Passive Infrared (PIR) sensor sends a wireless signal to the receiver from up to 100m/328ft away. Adjusting the receiver, you can choose to be alerted by a high or low chime or alarm tone, or instead, with just a silent LED flash. What's more, the receiver can pair with up to 50 sensors, effectively securing a large area. We offer many combinations of sensors and receivers, just choose what best fits your needs.

To avoid false alarms:
Don't mount the PIR sensor in direct sunlight (as moving heat sources would trigger the PIR) or in a place affected by wind. When installing outside, it's best to mount it in a shady, protected place with minimal changing temperatures. Also, avoiding mounting on UPVC or metal door frame surfaces which may reduce the transmission range.
