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:1/4 mile 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.)
