The sensor has a passive infrared lens that activates when it senses both heat and motion. When the sensor is triggered by a person, car, or large animal, a signal is sent to the receiver in your home that will alert you with the sound you choose from the zones. The ideal maximum range between the receiver and sensor is 1/2 mile. The sensor has a maximum 30ft detection distance and the sensitivity is adjustable with low(approx 20ft.) and high(30ft.) mode.

There's no wifi or monthly contracts required. Additionally, the system is weather-resistant and designed to work throughout the seasons. It works the same for day and night. It's perfect to be used to detect who's on your property, when the mailman arrives, and more, especially for rural areas with driveways.
