The 1byone 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 doorframe surfaces which may reduce the transmission range.
Love my new alarm.. it's very loud and is so simple to install.. Let me know when ppl are near my house and that is a plus! I feel safer with this device.
We use one of these near our front door and it works perfectly. They don't need to ring the bell because we know exactly when someone walks up to our front porch.We expect they will work just as well.
This unit seems to works well and was very reasonably priced! I wouldn't hesitate to recommend it to others.
Works great just like I needed! And I just might purchase another unit.
Delivered in a timely manner and worked as expected.Easy to install and very sensitive.highly recommend!
