WSDCAM Glass Break Sensor Alarm 125dB Ultra-Slim Wireless Glass Break Detector Window Alarm Vibration Sensor for Home Window and Door Security - 4 Pack

Until I found these units this year, 2020, I have never been able to find this item before where the battery compartment is not acessible and easy for the criminals to figure out. I purchased one brand and when the criminals entered my home, they dismounted the sensor alarms' batteries. That was going to be an expense to keep the unit. I LOVE these Wsdcam Glass Break Sensor Alarm units - finally the criminals will have to pull the paint from the front door to think about how they will dismantle the battery compartment. NICE - I have to applaud the company that finally got it together. These units are as described and recommend the purchase.Because once you have a home invasion, the perps can and most likely will continue to return to your home to collect stuff until they are satisfied. You still shop for stuff. Imagine someone you do not know in your home often looking through your stuff. It is an invasion of privacy. I added 3 of these units, another type of unit and a unit to the ceiling - all 125dB. The noise of 4 125 dB units is mighty loud. Please keep in mind that pets have sensitive hearing and just one of these 125 dB units is too loud for my dog.

I put 8 of them up on various windows. They work perfectly. As an example, I have one on the kitchen window, and when I was chopping something on the counter it went off. But you can adjust the sensitivity easily. You can turn them on and off easily. They're quite thin and small so fit practically anywhere and don't obstruct anything. They're very loud. Now some tips: Be sure to put them where you can get to them easily. And set them all up in exactly the same way, e.g., I have the on-off switch at 9:00 and the sensitivity adjustment at 3:00.

It really isn't motion detection though that is one of the categories for this review. It detects impacts\vibrations, not really motion. They are easy to install, quite thin, have adjustable sensitivity, and seemed to work just fine when I tested them. Another feature I like is that there is an off\on switch (I think all such items have one), but the words 'on and off' are on the inside, so those looking from the outside cannot tell if it is on or off. Sometimes the little things make a big difference.

These are an inexpensive way to stop a burglar. They do go off every once in a while, from a loud noise in a false alarm but they shut off after 45 seconds.I have installed 24 of them a year ago. When I went to replace the batteries, two of them were bad and had to be replaced.I don't think a burglar can get inside the house without these sensors making a loud noise to warn whoever is home.

Product works ok, however some sensor alarms have a much lower non piercing alarm than others in the set.

This is the second time I have purchased these alarms. I didnt want to run out, so I ordered more. My first set is still working well, loud and sensitive. I rest easier at night knowing that if anyone tries to enter the door window or other large window, they will get a surprise. It will give me enough time to get protection and police at the same time.

Easy to install and loud when motion on window is detected. Good for home “DIY” alarm system, and can draw attention when sounded.

Thank you

Its works as it should and the price is right.

Ça sonne croyez moi.Ça ne défait pas trop une déco non plus

It's very good. The only cons is that it maybe a bit on the expensive side.

The sensor seems to be working will. Very easy to install and apply the proper sitting and loud when it goes off. We had a wind storm recently and it never went off, but hitting the window will trigger it. So far happy with my purchase...Thnx
