Betterlink Solar Driveway Motion Sensor (Supplemental)

Betterlink Supplemental Solar Driveway Motion Detector & Sensor is a solar-powered, weatherproof PIR motion sensor that can operate alone or pair with receivers to monitor driveways, yards, and entryways.

This compact sensor extends your existing Betterlink driveway alarm network or functions independently as a standalone motion alert. Designed for easy mounting on posts, walls, or trees, it uses pyroelectric infrared detection and adaptive software filters to reduce false triggers while delivering around-the-clock monitoring. Power comes from an integrated rechargeable battery topped up by a built-in solar panel, with USB-C backup charging for shaded or low-sun locations.

How reliable is the motion detection for cars, people, and pets?

The sensor uses PIR technology to sense heat and movement within roughly 30 feet, distinguishing moving objects by their thermal signature. Intelligent filtering reduces alerts from swaying branches or small animals, while adjustable placement lets you tailor coverage to paths, driveways, or lawns.

• Infrared detection range up to 30 feet (approx. 9 meters)
• Advanced software algorithms to minimize false alarms
• IP65 weatherproof rating for outdoor use
• Suitable for people, vehicles, and larger animals

Can this sensor operate without a receiver and how far can it communicate?

Yes — the sensor can function independently to alert nearby occupants, or it can join a Betterlink receiver network. When linked, each sensor can communicate up to about 1/2 mile in open areas to a compatible receiver, and a single receiver supports up to 16 sensors for broad property coverage.

• Works independently or with Betterlink receivers
• Wireless range up to 1/2 mile (open area)
• One receiver can handle up to 16 sensors
• Selectable alert modes including audible and visual

What are the power options and operating conditions?

Primary power is supplied by an internal battery charged via the integrated solar panel, reducing battery swaps. For low-sun conditions you can recharge with a USB-C cable. The unit is tested for wide temperature extremes, making it suitable for varied climates.

• Solar-charged rechargeable battery with USB-C backup charging
• Tested operating range: -4°F to +140°F (-20°C to +60°C)
• Low maintenance with no frequent battery replacement required
• Durable housing rated IP65 against water and dust

How will I be notified when motion is detected?

The sensor supports multiple alert styles so you can choose what suits your property best: audible alarm, light flash, combined sound-and-light, or forwarding through a linked receiver. Alerts are immediate and configurable to reduce nuisance notifications.

• Four alert modes: audible, light, sound+light, or receiver-linked
• Quick notifications when motion enters the detection zone
• Compatible with existing Betterlink driveway alarm receivers for centralized alerts
• Placement flexibility to minimize unwanted triggers

Who is this for: Homeowners, renters, and small-property managers who need an easy-to-install, low-maintenance sensor to monitor driveways, gates, pathways, and yards. It suits anyone who wants battery life extended by solar charging, needs weatherproof outdoor monitoring, or wishes to expand a Betterlink receiver system up to 16 sensors for comprehensive perimeter coverage.
