Frequently Asked Questions

Does it trigger on knocking or tapping?

It’s calibrated for break-in force, not light tapping. Normal window activity shouldn’t trigger false alarms, but severe impacts will.

Where should I place it on the window?

Stick it directly on the glass pane, preferably in a lower corner. The sensor needs to be on the glass itself, not the frame.

How long do the batteries last?

Button cell batteries in standby mode last many months. The alarm only uses significant power when triggered.
