HTZSAFE Solar Driveway Alarm Wireless Motion Sensor 1/2 Mile

HTZSAFE Driveway Alarm is a solar-powered, weatherproof wireless motion-alert system that detects movement up to 70 ft and transmits signals up to 1/2 mile to one or more portable receivers.

This compact security and notification kit combines a solar-charged outdoor PIR motion sensor with a plug-in, rechargeable receiver to create an easy, low-maintenance alert system for driveways, yards, gates, and remote property entrances. Designed for DIY installation, the sensor keeps its internal battery topped by the integrated solar panel while the receiver offers selectable chimes, adjustable volume and a backup battery so alerts continue during power interruptions.

How reliable is the motion detection and how far does it reach?

The HTZSAFE sensor uses passive infrared detection to sense moving people and vehicles at adjustable ranges. You can fine-tune sensitivity to suit your site and reduce false triggers from small animals or foliage.

• Detection distance: selectable Low = 25 ft, Medium = 50 ft, High = 70 ft.
• Three sensitivity settings allow balancing range and false-alarm reduction.
• Suitable for driveways, walkways, garages, gates and poolside perimeters.

What is the effective wireless range between sensor and receiver?

Signals from the weatherproof sensor can reach receivers up to approximately one-half mile under favorable conditions. Actual range depends on local terrain, obstructions and RF interference, so placement matters for best performance.

• Maximum line-of-sight range: up to 1/2 mile (about 800 meters).
• Range reduced by walls, dense vegetation, metal structures or uneven ground.
• Expand system coverage by adding up to 4 sensors and unlimited receivers.

How does the solar power and backup battery work for outdoor use?

The outdoor detector includes a built-in rechargeable battery that is continuously topped by the integrated solar panel, reducing or eliminating the need for battery swaps. The plug-in receiver also has a rechargeable backup battery so audible alerts continue if AC power fails.

• Solar-charged sensor recharges even on cloudy or rainy days for continuous operation.
• Receiver plugs into AC and contains a built-in rechargeable battery for power outages.
• Low-maintenance operation: no frequent battery changes for the sensor.

Can I customize alerts and add more devices?

The system is fully expandable and supports multiple sensors and receivers so you can designate different chimes to indicate where motion was detected. This makes it easy to identify which area triggered an alert without running outside to check each sensor.

• Expandable up to 4 motion sensors and unlimited receivers for broad coverage.
• 35 selectable melodies and 5 volume levels — assign unique tones to each sensor.
• Plug-and-play pairing: simple setup with clear placement and labeling options.

Who this is for: HTZSAFE's solar wireless driveway alarm suits homeowners and property managers who want a low-effort, visible alerting solution for entrances, long driveways, remote gates, workshops and yards. It benefits anyone needing an easy-to-install, weatherproof motion notifier with long wireless reach and the flexibility to expand coverage or differentiate alert zones without running wires or frequently changing batteries.
