The voice alert motion sensor is a passive infrared receiver (PIR). It detects movement by a change in background temperature and transmits a radio signal to the voice alert base station that movement has been detected.

The voice alert motion sensors can be used indoors and outside. They are designed to withstand weather including rain and snow but are not designed to be submerged in water. When installed outside they do best when in a covered area and not in direct sunlight.

The voice alert motion sensors are designed to ignore small animals under 40 Lbs. To reduce the possibility for a false trigger caused by movement of a small animal it is recommended that the Sensor/Transmitters be mounted at a height of 7 1/2 feet above the ground. The lower the Sensor/Transmitters are mounted the greater the chance of picking up a small animal.
