Wsdcam Window Alarm Glass Break Sensor Alarm 125DB Ultra-Slim Wireless Glass Break Detector Anti-Theft Vibration Sensor Alarm For Home Door And Window Security - 4 Pack - Black Review

I liked the slim design and adjustable sensitivity. You can set it to even a slight tap of the window can set it off. It also resets itself. It sticks to the window very well so be sure to know you are sticking it where you want it to be. You don't have to worry about it falling off the window. The simple on/off switch on the side makes it extra convenient. You can even put it in your pocket if you don't peel off the sticky cover and use it as a body alarm by turning it on and setting it off…

Little big and bulky for a window, very noticeable. But excellent sensitivity and alarm. Very easy to install, pull off the sticky side, turn on the switch and rotate the dial to desired sensitivity. Warning tape is strong, I applied it to a window and couldn’t get it back off. Guess it does exactly what it is suppose to.

This device is easy to install & set up. To set the sensitivity, I simply attach the device to my window, tap on the window until the alar is triggered, then adjust the sensitivity accordingly. It works very well. Hopefully, we won't have to test it in real life. But at least, it provides a sense of security and the peace of mind that you will know when someone breaks the window.

These offer an extra piece of mind in addition to our security system. They are slim enough that should work on either panel of window / sliding door and shouldn’t interfere with opening and closing windows. They let off a pretty loud noise (125dB). Luckily, this can be adjusted with a sliding volume control on the side. There is also a on/off switch for convenience. Very easy install.

These little alarm sensors can get very loud with adjustable sensitivity! Very effective! Just peel and stick and you’re good to go. Give yourself time to react and be ready if someone ever breaks into your house!

Work as needed.I put one on my kitchen window. Also on the knob on my bedroom door if anyone tries to come in it will alert me someone has come in. Very pleased!

Our master bedroom is on thee other side of the house, pretty far from the rest of the bedroom where our children stay. These tiny but extremely loud alarms provide us piece of mind. The sound is very impressive and as loud as a house alarm almost, should they all go off at the same time. Like someone else mentioned, it gives us plenty of time to grab protection & approach. I’m sure our children feel safe and loved.

The alarms do work. I am using them . They are very sensitive to be set off , so I turn it on when I need them only. Just having them in view makes some people stay away from setting them off.

You get 4 small discs in this set – stick on alarms for any vulnerable windows or sliding glass doors. They have two controls on the sides, one to turn them on or off, and the other to adjust the sensitivity of the alarm. They are powered by 3-buttons each LR44 batteries that come with. They say they have a 1-year battery life, although we can’t vouch for that yet.There’s paper on the sticky back that you peel off and then just press the unit to the glass. For example, we wanted to protect the…

I'm not sure how long the battery life is due to just attaching them to my windows. However, the adhesive is very strong. I wanted to move one to another part of the window and it's not easily coming off. I'm fortunate to not have had a chance to review how well the alarm functions if the window breaks.
