Buying Guide

Choose the right sensor type

Match sensors to the task—magnetic contact sensors for doors/windows, glassbreak detectors for large windows, and motion or camera options for outdoor coverage

Consider connectivity and hub needs

Decide between LoRa, Wi‑Fi, or proprietary wireless ecosystems and confirm whether a hub or speaker hub is required for reliable range and remote alerts

Power and installation

Prefer battery-powered or solar-assisted devices for outdoor use to avoid wiring; check battery life and whether mounting hardware is included

Alerting and local audio

Look for built-in sirens, speaker hubs, or keypad access for on-site deterrence and convenient arming/disarming without relying solely on a mobile app

Compatibility with your smart home

Verify integration with your existing hub, routines, or third-party platforms to ensure sensors and cameras work together for automation and notifications
