Frequently Asked Questions

SimpliSafe false alarm triggered by my pet — how to prevent it?

Enable pet immunity on your motion sensors in the SimpliSafe app, or mount the motion sensor higher on the wall (pointing downward at about 30 degrees) to reduce the lower detection zone where pets move.

SimpliSafe false alarm in the middle of the night with no one home — what triggered it?

Check the event log for the exact sensor. Common overnight causes include HVAC drafts triggering motion sensors, thermal changes causing structural movement that opens door sensors slightly, or insects crawling on motion sensor lenses.

How do I cancel a SimpliSafe false alarm before police are dispatched?

In the SimpliSafe app, tap Cancel Alarm immediately. You will be asked to confirm your secret word (PIN or verbal password). Alternatively, enter your Master PIN on the keypad within the alarm window.
