Door Alarms for Kids Safety, 120dB Loud Window Alarms for Home Security, Pool Alarm Door Alarm Sensor for House Hotel Apartment Sheds Caravans, 2 Pack

I bought the Noopel Door Window Alarm 2 Pack to add a little extra peace of mind around the house, and they’ve exceeded my expectations. Setup was incredibly easy—just peel and stick. No tools, no wiring, and I had both alarms installed in under 5 minutes. What surprised me most is how loud these little things are! The alarm is piercing enough to grab attention immediately. I tested them on both a window and a back door, and they trigger exactly as expected when the door or window is opened. They’re perfect for apartments, dorm rooms, or anyone who wants quick, budget-friendly security without dealing with complicated systems. I even plan on ordering another pack for my garage door and basement window. Highly recommend if you want simple, effective protection that won’t break the bank.

—-Update—- Seller reached out and rectified the issue of receiving a used item as new. I changed to five stars because having a seller that stands behind their product is an important part of a quality product. —-Original review—- Bought these for use in hotels. My son sleep walks and was opening the door to the balcony on a 10 story hotel room. I am going to use painters tape to hook them to the door and not have to worry about damaging the door. The alarms are loud and the distance the sensing magnet triggers is perfect. The reason I took 3 stars off is because the packaging was torn open and put in a plastic bag and there was nothing to keep the batteries from discharging. I am hoping the batteries are not almost dead because it will probably cost more to replace the batteries than these alarms cost.

This is very loud, which is exactly what I wanted. I wanted to put it in my child's bedroom on their window as our windows aren't the greatest in our new home and a neighbor recently did something that kind of made me feel uneasy so I decided to get an alarm for peace of mind. I would definitely be able to hear this from our bedroom. Comes with batteries and is pretty sticky adhesive on the back. No screws or anything needed. I will show a picture of what I'm talking about but if your windows aren't flush you'll have to find some way to angle the alarm to match up with the arrow. Even if they are matching, if it is uneven the alarm will set off until it's fixed. Other than that, this is great and gives me wonderful peace of mind!

Easy to install. Peel the tape and put the alarm on the door and the smaller sensor on the door frame. Turn the switch off if you want to keep the door open. Switch it back on when you want to close the door for the night or whenever. It is a small device but has a loud alarm which I like. Keep the package so you know what kind of battery to buy when the time comes. Good buy for the money.

These work great for my entry doors. The devices are well made & do not feel cheap. I have a decorative molding frame around my doors that makes it difficult to mount these devices in the same plane & closer than a 1/4 inch. The first product I ordered would not work on my door frames for those reasons. This works great. On one door I had to place the large alarm portion on the frame which meant that it was at an angle to the smaller portion that is mounted on the flat door (the decorative door framing prevents anything mounted on it to be flat & in the same plane as the door). The sticky tape on the back covers the entire portion of each piece & it sticks very securely to even my semi-gloss paint on the door & framing. The large portion sticks securely to the frame even though there is not a completely flat portion on the framing large enough to accommodate the entire back of the large piece. My other door worked out better because it opened inward to the left which meant that I could mount the smaller portion on the framing. The frame does have a space wide enough that the smaller piece could mount flat on the narrow portion of the framing. There is at least a 1/4 inch gap between the pieces on both my doors & it probably would accommodate a little larger gap if necessary. The alarm is loud, but not so ear damaging that it is painful. I will not have any problems hearing it all over my 1400 sq foot home. The alarms stops immediately when the door closes (in case you open the door without turning the alarm off). It will only alarm if the magnetic connection remains broken. I have very secure windows that have been installed in my home that would pretty much require breaking them to enter. I just wanted something that would alert me that the door had been opened. I am disabled & only leave my home for a few hours a week so I really did not need anything for when I am away. I just don't want anybody coming in on me unawares. My chihuahua would bark, but she is not big enough to scare anyone off. I am at the age that I am not willing to die for anything that I have in my home except maybe my chihuahua. I will just open my bedroom floor length window & leave with my dog. I am not planning on sticking around & fighting with anybody. I also sleep with a taser type flashlight (bought for protection after dangerous dogs attacked my dogs multiple times when walking) in my bed that would pretty much knock anyone out enough to allow me to escape. My neighborhood is fairly safe. It is more for psychological peace of mind then anything else. I sleep better knowing that the alarm is there to notify me if the door is opened. It works better than the large bells that I had hanging from the doorknobs previously. The dog will be happy that the bells are gone as they scared her to death every time I opened the doors!

Easy (adhesive) mounting. Fairly loud alarm but not enough to alert neighbors unless they are next door. If you have an out building it is not nearly loud enough to be heard inside your house. It’s not very secure. It has a visible on-off switch so it has to be mounted inside of the building. If not, it can simply be disabled before the door is compromised. If a bad guy triggers the alarm they just need to shut the door behind them and the alarm shuts off. Or, if they have any experience at all they will just turn it off with the side button. Plus, if you turn it on it will go off when you open your door to exit the building, shut the door, and lock it. If you want a simplistic alarm that may make enough noise to scare away the bad guy this will work. It’s not effective for anything else. You get what you pay for.

These work really well. Just get some extra double stick gorilla tape. My son got a chair and pulled these off gorilla tape worked it putting them back

Was not delivered. I received 3 items and not this being the fourth. One was in a separate bag and the other 3 in a large box. I assume this item was did not make in the large box. This is not the drivers fault , but the packers. Update The package arrived today in a plastic bag. I would give the door bell ringer a 5. Ie is very loud and very easy to install. for people that need some type of warning. hat this is a very good and inexpensive choose.
