What should I do if the alarm goes off accidentally?

How do I clean the motion sensors?
Use a soft dry cloth to gently wipe the lens and casing. Do not use water, solvents, or abrasive cleaners. Avoid touching the lens directly.
What does the tamper protection feature do?
Tamper protection triggers an alarm if someone attempts to open or remove the control unit or sensors. This ensures the system cannot be disabled without alerting you.
