The Borderguard is designed to protect the exterior of a building or fence. Borderguard is a PIR (passive infrared motion detector) which detects the heat energy emitted by humans. The detector utilizes dual beams that project 40 feet from each side of the unit and is best mounted at a height of 36-48 inches. Both beams must be blocked at the same time to activate the detector. This feature eliminates the potential of false alarms caused by animals in the outdoor environment. It can operate normally between -4°F and 122°F and is weather resistant. The 3V and 9V lithium batteries included will typically last for 2-3 years.
