US Patrol Wireless Watchdog Personal Security Monitor

Long Distance Motion Detection Works on the Driveway or the Door! Attach the Wireless Watchdog sensor nearly anywhere and when it detects motion, it sounds an alarm and flashes LED lights on the receiver. Place the sensor at the end of your drive for advance notice of arrivals, or near a doorway so you'll know when someone enters or exits. Place the device near a window to detect intruders or on your front door to detect approaching visitors. please email me if you have any questions before placing your order sale as is final.
