Product Description ------------------- Description: Keep track of the comings and goings on your property with this motion-activated alert system. When a vehicle or person passes the sensor, the receiver emits an audible tone and lets you know someone's there. Use it to monitor the mailbox, the driveway, the garage or the front door. Battery power and 400-foot range means no wiring is necessary. Notes: Operates on three C-cell batteries or one 9-volt battery (Batteries Not Included) When a visitor-wanted or unwanted-approaches a house on foot or in a vehicle the motion-detecting sensor unit of this warning device sends a signal to the receiver indoors, which chimes an alert. The device is wireless and has a 400-foot range. It requires three C-cell batteries for the receiver and one 9-volt battery for the transmitting sensor. (Batteries are not included.) The sensor is housed in weather-resistant plastic, installs with a screw on any surface, such as a mailbox post, garage, or door, and measures 4-1/4 inches high, 2-5/8 inches wide, and 2-1/4 inches deep. The portable receiver has an identical housing, can be set to chime high or low (or turned off), and measures 5 inches high, 3-5/8 inches wide, and 1-1/2 inches deep. -Fred Brack .com ---- When a visitor--wanted or unwanted--approaches a house on foot or in a vehicle the motion-detecting sensor unit of this warning device sends a signal to the receiver indoors, which chimes an alert.
