Why Smart Door Sensors Matter

Every entry point is a security risk — whether at home, in the office, or a rental property. Door sensors send instant alerts, can trigger lights or sirens, and give you full control even while you’re away.

Choosing the Right Sensor for 2025

Look for app UI, battery life (6–24 months), range (Bluetooth, WiFi, Zigbee), installation method, and integrations with other smart devices. Some models even support local sound alarms or tamper detection.

FAQ

Do I need a smart hub?
Most 2025 models are WiFi-enabled and work standalone with a phone app, but Zigbee/Z-Wave versions may need a hub.
Can I use these on windows or cabinets?
Absolutely. Most door sensors work anywhere you want entry alerts — including windows, drawers, safes, or even mailboxes.
Do they work with Alexa routines?
Yes — most top sensors support Alexa, Google Assistant, or HomeKit for routines, automations, and voice alerts.
