The motion detector is specifically designed for outdoor environments, featuring a weather- housing that withstands rain, snow, wind, and extreme temperatures. It maintains stable performance in a variety of harsh weather conditions, providing reliable protection all year round.

This solar wireless driveway alarm provides a dependable 400-meter transmission range between sensor and receiver, ideal for monitoring driveways, yards, , and property perimeters. Solar panels continuously charge the built-in battery, reducing the need for frequent maintenance and ensuring round-the-clock operation. Advanced wireless technology delivers up to 400 meters (open-field) transmission distance from the outdoor motion sensor to the indoor receiver. This extended range allows flexible installation for large driveways, long lanes, farms, and wide residential or commercial properties. This security alert system is designed for simple DIY installation. No complicated wiring is required: mount the solar sensor in the desired outdoor location, plug in and pair the receiver, and adjust detection angle and range as It is suitable for both beginners and experienced users., Manufacturer: Aundhegrtt
