4vwin Driveway Alarm provides a convenient and economical way to alert you to the moment when someone is approaching your home before you see them. Perfect for long or hidden driveways to allow you just a little extra notice before guests (or intruders) arrive. 3 Alert Options: High Volume Alarm / Low Volume Alarm / Off When motion is detected, the passive infrared (PIR) sensor sends a wireless signal to the receiving unit up to 100 meters away. Using the receiver unit, you can choose to be alerted by a high or low chime. What's more, the receiver can pair with up to 50 sensors, giving the ability to secure a large area. We offer many combinations of sensors and receivers, just select the system that best suits your needs. To avoid false alarms: Do not mount the PIR sensor in direct sunlight (as the PIR detects moving heat sources) or in a place affected by wind. When installed outside, it is best to mount in a shaded and protected location with minimum change temperatures. Also, avoid mounting on UPVC or metal door surfaces that can reduce transmission range.
