Never be surprised by visitors again with this solar-powered wireless driveway sensor! This isn't a standalone unit - it works with HTZSAFE alarm systems to alert you when someone enters your property. The solar charging means you never have to replace batteries - it keeps itself powered up using sunlight. With an impressive 1/2 mile wireless transmission range (under ideal conditions), it can monitor even the longest driveways or largest properties. The detection range is adjustable too - choose from high sensitivity for 70 feet, medium for 50 feet, or low for 25 feet coverage. Built to handle all weather conditions, it works perfectly from -30 to 150 degrees Fahrenheit, so it'll keep monitoring through snow, rain, or intense summer heat. The advanced FSK+FHSS wireless technology prevents interference from other devices, ensuring reliable alerts. Perfect for driveways, walking paths, gates, pools, or any area where you want advance notice of movement. HTZSAFE has over 20 years of experience in solar alarm technology, and this sensor comes with a solid 2-year warranty. Get peace of mind knowing you'll be alerted to visitors, delivery drivers, or anyone approaching your home.
