Review on Wsdcam Door And Window Alarm For Home Wireless Alarm Security System Magnetic Alarm Sensor Close Door Reminder Loud 110 DB, 4-In-1 Mode Window Alarms 10 Pack by Jesse Jewett

These little devices are simple to install, program and operate. I ordered 14 in total and all of them work perfectly. They come neatly packaged one per box and are each equipped with a battery. There are 4 alarm types to select from, which are programmed by turning the unit off and on anywhere from one to four times in a row. You must allow the unit to chirp while in the on position before turning it off, then quickly back on, wait for chirp, then off again until you’ve switched it the directed amount of times for the desired alarm. The settings are printed on the outside of the small box they come in.I worried it would not work on my entery doors as upon installation there had to be a small gap as well as a depth difference between the alarm unit and the other piece of the alarm on account of our door trim style but it works exactly as it should.In order to provide increased protection at our windows, I located the alarm portion of the device at the bottom center of the glass itself and put the other piece below the sash on the frame, thinking there would at least be a potential for the alarm to sound in case of glass breakage and it would of course still work as designed if the window were merely opened. This arrangement works well too, even through the two pieces of the unit are separated by the handle to open and close the window. I don’t know why i can’t add pictures but hopefully my description makes sense. I do feel applying it to the glass rather than the frame enhances functionality considerably as window locks generally prevent opening and intruders break the glass in that case.I’ve already recommend these to my daughter who lives alone and would highly recommend them to anyone concerned for being immediately aware of attempted intrusion or of occupants attempting to exit the premises. We used devices similar to these with my grandma who had dementia so she couldn’t wander off undetected. They worked too but were way more expensive than these.I think they could deter a thief even if no one was home to protect the property as many monitored home security devices sound a constant alarm like these sound so who’s to know if authorities have been alerted or not. Sticking around with an obnoxiously loud alarm going off is probably not the best idea regardless of if the homeowner intervenes.
