H HOSMART Driveway Alarm Wireless Sensor 1/2 Mile

HOSMART's 1/2 Mile Driveway Alarm is a weatherproof wireless sensor system that alerts you indoors when vehicles, people, or large animals enter your driveway or perimeter.

If you want a straightforward, expandable alert system that installs in minutes and communicates reliably over long distances, this HOSMART kit provides a bright yellow outdoor sensor and a newly upgraded square receiver with more ringtone choices. It runs on AA batteries for the sensor and either batteries or the included adapter for the receiver, and its robust enclosure and sunshade are built to stand up to outdoor conditions.

How far will the HOSMART driveway sensor reliably transmit alerts?

The system is designed to deliver dependable signals up to one-half mile in ideal line-of-sight conditions and commonly reaches about 1,500 feet through typical yards with trees and buildings. Real-world testing shows it holds up well across various weather and terrain challenges.

• Advertised range: up to 1/2 mile in ideal open conditions
• Typical range: ~1,500 feet through residential obstacles
• Tested through rain, snow, heat, wind, and dense foliage

What detection types and settings does the sensor support?

The outdoor sensor detects the motion of cars, people, and larger animals using passive sensing tuned for perimeter monitoring. The sensor mounts on a swivel bracket so you can fine-tune its detection angle, and battery life is optimized for long-term use.

• Detects vehicles, people, and large animals
• Swivel mount for angle and focus adjustment
• Sensor powered by four AA batteries (long life; ~one year typical)

Can I expand the system or customize alerts for different entry points?

Yes — the HOSMART system supports up to four sensors per receiver and an unlimited number of receivers, letting you cover multiple driveways or gates and hear separate alerts in different rooms. The receiver includes a ringtone selection button with 38 tones, so you can assign distinct chimes to each sensor location.

• Expandable: up to 4 sensors per system and unlimited receivers
• 38 ringtone choices on the upgraded square base station
• Choose different chimes to identify which sensor tripped

How weather-resistant and durable is the HOSMART outdoor sensor?

The housing uses industrial-grade PVC and a rubberized seal to resist water and dust, plus a sunshade to limit false triggers from glare. HOSMART supplies a 2-year warranty on parts and workmanship and a 90-day risk-free window to test performance in your environment.
