Buying Guide

Decide on detection range

Match sensor range to your property — driveway systems list distances from about 100 m to half a mile, so choose one that covers your needed span

Pick a power source

Solar units reduce battery swaps, while battery-powered sensors can be placed where sunlight is limited

Check wireless protocol and range

LoRa and long-range RF systems offer better penetration and distance for large properties than short-range wireless

Assess outdoor durability

Look for weather-resistant housings and IP-rated components if the sensor will be exposed to rain, sun, or snow

Consider receiver features

Receivers with multiple chimes, adjustable volume, and multi-sensor support simplify distinguishing different trigger zones
