Keep an eye on the cars entering or exiting your property with the Mighty Mule Driveway Alarm System.The electromagnetic sensor will sense huge metal objects and send a signal to the inside base station to let you know when somebody is there.

Make sure to install the batteries, close to the installation site so that the sensor can "learn" the area.If the batteries are installed in the home,the unit may not function properly.

Highly straightforward to use & install sets up in minutes.The Sensor has a 30-ft range & can broadcast a signal to the receiver up to 1200 ft away .It Detects humans & autos even though it ignores animals.

Water-proof sensor assembly with Weather shield included to guard sensor from the elements .the Receiver features sound control & has an output to fire external alarms or bells. I am using it for my driveway- the motion sensor is set up about 200ft from the house and the signal has to go thru 150ft of woods, thru a 6 in. exterior wall, and an interior wall with no reception issues.

I've had nil fake alarms from little animals and there are plenty of them here in the woods.

The improved Wireless Drive Monitor sends a wireless signal to your house to warn you when a unannounced auto enters your drive.The receiver chimes and the caution light flashes red for approximately fifteen mins.

The driveway sensor uses a patent-protected magnetometer sensor system. It will not be tripped by animals or people walking by your property.

The sensor might be placed so far as one thousand feet,line of sight, away from the receiver in your house.For best performance, mount the sensor on a 4x4 post, 4 to 8 feet off the ground.
