振動ガラス破壊センサー

Got it mounted on my sliding glass door last night, and the vibration detection picked up a light tap from across the room within seconds. The setup was straightforward, and I like that it's small enough to blend in with the frame. Feels like an extra layer of safety that doesn't get in the way.

The sensitivity adjustment is spot on—I tapped the window with a key and it triggered instantly, but a passing truck outside didn’t set it off. Setup took under five minutes, and now I actually sleep through the night knowing the sliding door is covered.

Installed this on a sliding glass door and the shock detection is spot on—it caught a heavy knock without any false alarms from the dog bumping the frame. Setup took under two minutes and the response feels instant.
