The Doberman Magnetic Window/Door Alarm is a sleekly designed unit enabling it to function with sliding glass windows and doors. The magnetic Window/Door Alarm is triggered by both window vibration and entry opening. Place the included magnet on the outside frame of any window or door you wish to protect. When opened by an intruder, the magnetic circuit is broken and a loud alarm will sound. The alarm unit will also sound when window vibration is detected. Printed on the reverse side of this product is a red warning label that can be seen outside through the window. It notes that your property is protected by Doberman and deters potential burglars. Its ultra-thin profile makes if perfect for sliding glass doors.

Glass breakage vibration sensor WORKS!
We have lived in a wonderful neighborhood for over 20 years where everyone helped each other and loved living here......until the wienie next door moved in. While his character is questionable, that of his friends leaves no doubt. We felt it necessary to put some sort of alarm on our french doors just in case someone would think of looking for a way to get some fast cash. Hence, the french doors our weakest point. I ordered two of these alarms in white. Put them up with the senors on the door at the top of the frame with the alarm itself on the casement. They worked as stated. Then our daughter and son in law came over. Our son in law, who we seriously just adore, asked what "those" are. I explained the Doberman alarm. He kind of giggled, then said, "what if they break the glass." Ah Ha! Well, my dear, they also have a vibration sensor. To this, he took his fist and hit the edge of the door, and the alarm went off! He that "okay, well that works" look. The alarm is LOUD, which is what you want. It's fast and easy to install. As my retired police officer friend and police officer son of my best friend said, "an alarm is only as good as the attention it draws." And this it does do! Only draw back: Amazon, please STOCK these items in both colors. No one wants to wait 2 to 4 weeks. Please.

Nice loud alarms, but very vibration sensitive.
I’m using these for door and window alarms for our camping trailer. The thin alarm units are convenient to mount and generally great for sliding window systems as advertised, but be aware that they are extremely vibration sensitive so that tapping on the window (or wind blowing against the glass) may set off the alarm.

Highly effective
These are fantastic! Crazy loud — they scare the daylights out of me every time I forget they're set. :) The only thing to be aware of is: if you have curved moulding around your door, it's tricky to line the two parts up.

Its great, the louder the better
Its great, the louder the better!! The slim-line design is wonderful! When it arrived, I thought I only had one piece of my 2-pack order, not knowing it was two pieces, that's how slim it is.

Very nice product
I am writing this after using it for more than 1 1/2 yers of continue use. It’s perfect product. Battery last for nearly 10 to 12 months. I have more than 10 of these units.?in some units, after battery replacement the battery cover is not closing properly so that al batteries are not powering the device. A small paper under the lid solves that issue. If your door/windows vibrate during thunderstorms, it can give a false alarm. But this is a small inconvenience compared to the safety and piece of mind it will give
