PLAN BEFORE BUYING

Smart home security: sensors, cameras and locks

Define the event first: an opened door, movement, a water leak or a visitor. Each needs different hardware and operating conditions; sharing an app does not guarantee full interoperability.

Check these before choosing

  • Check the power source, expected battery life and low-battery alerts for the model.
  • Verify sensor-to-gateway compatibility, coverage and installation location.
  • Review camera storage, subscription requirements, sharing permissions and privacy.
  • For locks, check door thickness, mortise dimensions, opening direction and backup entry.

Limits and total cost

Notifications may be delayed or unavailable during network or power outages. Consumer smart devices do not automatically replace a certified alarm or fire-detection system; check each device’s approval and intended use.

Displayed prices cover the specified device or variant. Gateways, accessories, wiring and installation may be separate; request an itemised quote after a site review.
