Buying advice

Consider compatibility with your existing home security system. For smart home users, choose a sensor that integrates with your hub (e.g., Ring, Wyze). For basic security, a simple contact alarm may suffice. Look for pet immunity if you have pets, and consider dual technology sensors for fewer false alarms.
