HOSMART Wireless Driveway Alarm Sensor 1/2 Mile Range

The HOSMART 1/2 Mile Wireless Driveway Alarm is a weatherproof outdoor motion sensor system that notifies you with sound and light when people, vehicles, or large animals move within about 30 feet of the sensor.

This compact kit pairs a rugged, weather-resistant sensor with a versatile receiver to create a simple perimeter alert solution for homes, farms, worksites and businesses. The sensor mounts outdoors and runs on AA batteries while the receiver plugs into AC power or runs on batteries, letting you locate alerts where you need them. The system is designed for do-it-yourself setup and expands easily to cover multiple entry points.

How far will the HOSMART driveway sensor communicate with the receiver?

Under ideal conditions the sensor and receiver can maintain a wireless link up to a half-mile apart, but real-world obstacles like trees, walls or heavy weather reduce that distance. Typical residential installations commonly achieve around 1,500 feet of reliable range in mixed environments.

• Maximum theoretical range: 1/2 mile in open line-of-sight.
• Common practical range: ~1,500 feet through typical yard obstructions.
• Tested in varied weather — rain, snow, wind and heat.

What detection and alert options does this system offer?

The outdoor sensor detects motion from vehicles, people, and large animals within roughly a 30-foot radius and includes adjustable sensitivity to reduce false triggers. The receiver provides both audible chimes and visual indication, and you can assign different chime tones if you add multiple sensors to identify which zone triggered.

• Detection radius: up to ~30 feet depending on placement and settings.
• Adjustable sensitivity control on the sensor for fine-tuning.
• Selectable chimes on the receiver to distinguish multiple sensors.

How easy is installation and system expansion?

Setup is quick and intended for non-technical installers: mount the sensor, insert batteries, plug in or battery-power the receiver, and sync. The system supports expansion — add up to four sensors per receiver and unlimited receivers — so you can scale coverage across driveways, gates and property boundaries.

• Quick Start Guide included for fast DIY setup in minutes.
• Expandable: up to 4 sensors per receiver and unlimited receivers for multi-point monitoring.
• Batteries power the sensor (4x AA) and receiver can use AC adapter or AAA batteries.

What are the build and power features to expect outdoors?

The sensor uses industrial-grade PVC housing with rubber seals and a sunshade to protect electronics from weather and UV exposure. With four AA batteries installed, typical sensor runtime can approach a year under normal use, and the receiver includes a low-battery indicator to remind you when service is needed.

• Durable weatherproof housing with rubberized sealing and sunshade.
• Sensor powered by 4x AA batteries (not included); energy-efficient operation.
• Receiver can run from included AC adapter or rechargeable/alkaline AAA batteries.

Who is this for: homeowners, landlords, small-business operators, farmers and property managers who need an affordable, easy-to-install alert system to monitor driveways, gates, yards and worksites. It suits anyone wanting early notification of arriving vehicles or visitors without complex wiring, and it scales when you need multi-zone coverage.
