HTZSAFE Solar Wireless 2-Beam Driveway Alarm — 1/4 Mile Range, 190 Feet Sensor Span, Solar‑Rechargeable Lithium Ion, IP66 Weatherproof, Up to 32 Sensors

Overview: HTZSAFE’s solar wireless driveway alarm uses paired 2-beam active infrared sensors to protect driveways, gates, fence lines and other outdoor perimeters. When both infrared beams are interrupted by a person or vehicle passing between the sensor pair, a wireless alert is sent to the receiver up to 1/4 mile away. The two sensing terminals can be positioned as far as 190 feet apart for wide-area coverage. Detection and placement: Sensors operate in matched pairs and rely on active infrared detection. Mounting height and beam angle are adjustable so you can minimize false triggers from small animals. Install the sensing terminals up to 190 feet apart for optimal coverage. Power and installation: Each solar sensor contains built-in lithium ion batteries that are recharged by the integrated solar panels during daylight. The system is cordless and requires no wiring, making installation straightforward. In periods without natural light the internal batteries can support 3-5 days of operation (note: the system is not intended for long-term indoor use). Receiver and alerts: The wireless alarm receiver offers 4 volume levels and 35 selectable ring tones. You can assign different chimes to different sensors around your property to quickly identify where motion is detected. The system is fully expandable — up to 32 sensors can be paired to one receiver, and a single sensor can be linked to unlimited receivers. Setup and calibration: Each solar sensor includes a self-calibration feature (calibration hole) that allows long-range calibration to be completed in minutes. Durability: The sensors feature an IP66 fully enclosed design for resistance to rain, fog and snow, and operate across a wide temperature range from -40℃ to 70℃. Applications: Ideal for driveways, fence tops, windows, entrances and other outdoor intrusion-detection needs. No wiring, solar recharge, and easy installation make it suitable for DIY security perimeter monitoring.
