Solar-Powered Driveway Monitor

Place this monitor in full sun at the entrance to your driveway and you'll always know when someone's driving up to your house. Wireless solar-powered monitor requires no batteries and transmits a signal whenever a vehicle passes by, triggering a beeping sound and flashing LED lights on the in-house receiver. Signal transmits up to 1, 000'. Solar sensor detects only large, metal objects - it can't be triggered by kids or animals. USA.
