The Mier DA500 hard-wired driveway alarm senses when vehicles pass and alerts you in your home or office. This system detects moving metal so that you do not receive "false alarms" from deer, dogs, or other animals. The fact that this system is hardwired means you do not have to worry about changing batteries and it can be completely invisible to visitors. 

To set up you simply bury or clamp the white probe sensor so that it is protected from lawnmowers and snowplows and so that it does not move. Run the wire to where you want to have the control panel. 

*Mier HIGHLY recommends burying the cable in a 1/2-inch PVC pipe for added protection to the cable

You can add wireless chimes and light kits to your system for a more automated visitor alert system!

Includes: Internal chime with volume control and choice of three different chimes
