Make A Quiet Opening Hard To Ignore
That Click Shouldn't Leave You Guessing
You're in bed. A click at the window leaves you listening for the next sound, wondering whether to get up and check again. Give that entry point a voice: this door and window alarm delivers a high-pitched warning of up to 130 dB when triggered, so an opening doesn't have to stay quiet.
Catch Trouble Before The Door Gives
A knock on glass. A probe at the lock. The vibration sensor catches it instantly—an ear-piercing 130 dB blast erupts before they breach the frame. The magnetic sensor doubles down, ensuring even slow, forced openings don't go unnoticed. You're not reacting in the dark anymore; you're alerted and ready.
Your Front Door. Not Another Subscription.
You rent the apartment, but you still decide how you prepare it for the night. This battery-powered alarm works without wiring, a hub or Wi-Fi, with a physical ON/OFF slider you can check yourself. You get a local warning at your entry point—not another monthly bill or another app to manage.
Not Every Opening Needs A Siren
Your patio door at lunchtime needs a different response from your bedroom window at night. Use the side SET button to choose among five operating modes, including chime and vibration-warning options. Adjust volume and vibration sensitivity to suit the opening instead of accepting one fixed response.
Leave The Drill In The Drawer
Clean and dry the mounting surfaces, attach the supplied 3M adhesive, then line up the triangular markers. The magnet fits on either side of the main unit, so you're not locked into one door orientation. Keep the pieces close when closed and test the opening; the matte white casing keeps the setup unobtrusive.
Move In With More Than A Lock
Your first night in an off-campus rental is the wrong time to wish you'd added a door alarm. Before back-to-school move-in, put a local warning at the entry point you control. At $29.99 instead of $49.97, you save $19.98 upfront—and there's no monthly subscription waiting behind the purchase.
Don't Just Detect The Opening
A contact-only alarm waits for separation. This alarm also detects vibration, giving you a way to sound a warning before a door or window opens.
