How large of an area do the Sensor/Transmitters monitor?
The Sensor/Transmitters come set from the factory with a downward fan pattern and are designed to monitor a 40-foot by 40-foot area when they are installed at 7 1/2 feet above the ground and there are no obstructions. Additional information on this topic can be found in Section IX of the Operating Instructions. • How should I mount the Sensor/Transmitter if I want to detect vehicles coming up my driveway? For best results when installing to monitor vehicle activity, mount the sensor at 30 to 34 inches above the ground and angle it toward an oncoming car’s radiator. Since the sensor uses infrared technology to detect activity, aiming the sensor to the hottest part of the car will insure maximum results. • Will birds or dogs or cats trigger a false signal? The Sensor/Transmitters 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/
