Betterlink Driveway Alarm System — Solar 1/2 Mile Range, IP65 Weatherproof, 120dB Alert (Gray)

The Betterlink Driveway Alarm is a solar-powered wireless motion detection system that notifies you up to a half mile away with a 120dB alert and IP65 weatherproof sensors.

Keep driveways, gates, and remote property access points monitored without running wires or replacing batteries. This kit pairs a weather-resistant PIR motion sensor with a loud receiver and supports expansion up to 16 sensors, giving layered coverage for homes, farms, workshops, and rental properties. Built-in solar charging plus USB-C backup and multiple alert modes let you customize how and when you get notified.

How will this system detect vehicles and people?

The sensor uses pyroelectric infrared (PIR) technology to sense heat and movement, then sends a wireless signal to the receiver. It detects objects up to about 30 feet away and can reliably distinguish moving heat sources using updated detection algorithms to reduce false triggers.

• PIR sensing range: up to ~30 feet for moving heat sources
• Improved algorithm reduces wind/ambient false alarms
• Detects people, cars, and animals when crossing the beam
• Mountable on posts, walls, trees, or gates for flexible placement

What is the practical wireless range and expansion capability?

In open terrain the sensor can transmit signals to the receiver up to approximately 1/2 mile. The receiver supports pairing with as many as 16 wireless motion sensors, so you can create overlapping coverage across large properties or multiple entrances.

• Line-of-sight wireless range: up to 1/2 mile (open area)
• Single receiver supports up to 16 sensors for full-property monitoring
• Sensors work independently or together with the receiver
• Suitable for driveways, yards, barns, and remote gates

How do I power the sensor and what are the alert options?

The sensor is powered by an internal battery that is recharged by an integrated solar panel; a USB-C port provides an optional wired charge. For notifications you can choose audible, visual (light), combined sound+light, or use the receiver to broadcast alerts inside a building.

• Primary power: solar-charged internal battery; USB-C charging available
• Operating temperature: -4°F to 140°F (-20°C to 60°C) for year-round use
• Alert modes: 120dB audible, light flash, sound+light, or receiver notification
• Adjustable mounting and angle for optimal solar exposure and detection

Who is this for? The Betterlink Driveway Alarm is designed for homeowners, small-ranch operators, vacation property managers, and anyone needing a simple, wireless perimeter alert. It’s particularly useful where wiring isn’t practical and where you want multiple sensors feeding a single indoor receiver. If you need scalable coverage, weatherproof hardware, and flexible alert choices with low maintenance charging, this system fits those needs well.
