SECRUI Door Alarm for Home Security, Window Sensor, 120dB, 4 Modes, Easy Installation, Security Alarm for Kids Safety Home Garage Apartment Office (2 Pack)

These are awesome. They’re very loud for as little as they are, Also love the different sounds that it and has a very easy to operate.

This is a very good little motion detector sensor for the money. We recently had our pool installed & this was the sensor our builder got us. It came with 2 separate sensors. We installed 1 on our sliding back doors & 1 on our basement door. It works for sure, but the best part about this style sensor is that it’s super easy to turn on & off. You just slide the button up or down & it’s easily reachable while attached to the door. We have a very large home but this is pretty loud. You will hear it for sure. Also, it does not sound like any other random device when it goes off. So it’s got it’s own sound, which is very nice. In other words, you won’t think eh it’s just someone’s car alarm or phone or something else. No. You know it when this thing goes off. If you have children, this is a great little device to install on your doors. And when I say install, I mean, simply load it with the right batteries, stick it up on your door & slide the button to activate. Super simple.

Bought this to keep my husband inside at night, he has dementia. Was unable to install 1/2 of the magnet door the door frame because the frame does not have a flat surface. Otherwise I think it would have worked

This thing is sweet. I bought it because my autistic son just learned how to unlock our deadbolt and found himself in the hallway. I’ve added this, along with a door knob cover, and feel prettt good about it. This is super loud, and I’ll be using the alarm at night but even the door bell chime is not a pleasant sound, not ideal if it’s not for safety but amazing for safety

The product is fine, but the adhesive pieces that come in the box are USELESS. So do yourself a favor and go to Home Depot and purchase better adhesive tape to use instead of what is provided with the product.

Doesn't stick to the wall very well falls off the stickers that come with it could be better

had um on my desk to install, forgot about them. Now they are gone. WTF!!!they are loud.they are very basic.they may be sentient!

we were required to install an alarm on the sliding door before we sold the house because of the pool in the back.the price was good and these were really easy to install.when I tested it the sound was very loud it should work great.I'm not sure of the battery life because we haven't had it long but I have the other one to install somewhere at the new place so should know how well it works then.
