Protect your home with the world’s only motion-activated security camera with built-in floodlights, a siren alarm and two-way audio, so

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. False alarms are minimized due to an adjustable detection width option for the sensor "eye" and a swivel mount to focus the detection angle of the sensor. SUPER EASY TO INSTALL- Quick Start Guide has you operational in minutes! Expandable up to 16 sensors and unlimited receivers for complete coverage of your perimeter. Over 30 fun & unique chimes to choose from. Match different chimes with different sensors around your property to differentiate where motion is being detected. Detects movement from humans, cars, and large animals. REALISTIC 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 (please note: extra heavy interference such as thick walls, metal siding, tall hills, and many trees will diminish the wireless range).
