Mighty Mule Wireless Driveway Alarm (FM231)
Brand: Mighty Mule
Color: Multicolor
Instantly alerts you when someone pulls into or out of your driveway
The outdoor electromagnetic sensor only detects vehicles; no false alarms due to animals, children, etc.
Easy-to-install Electromagnetic Sensor Wand is buried next to your driveway, and detects mass metal moving within a 3-12 ft. radius of the wand.
When a vehicle passes by the sensor, an outdoor transmitter communicates wirelessly to an internal base station up to 400 ft. away and sounds a pleasant chime
Ideal for home and business
