Refurbished Guardline 500 Ft. Wireless Driveway Alarm
SUPER EASY TO INSTALL: Quick Start Guide has you operational in minutes! Set includes one sensor & one receiver. Expandable up to 16 sensors and unlimited receivers for complete coverage of your perimeter. Over 30 chimes to choose from. Match different chimes with different sensors around your property to differentiate where motion is being detected. LOUD & adjustable volume.
EXTREMELY DEPENDABLE: Two years of testing went into developing a reliable motion detector that will dependably alert you to motion around your property. Tested through thick forestry, hail storms, gusty winds, heavy rains, scorching heat, and snow. Minimal false alarms.
REALISTIC & RELIABLE RANGE: 500 ft long range has been tested in real world settings with trees, buildings, walls, and vehicles in order to make true and realistic wireless range claims (extra heavy interference such as thick walls, metal siding, tall hills, and many trees will diminish the wireless range.)
