Door Window Alarm 2 Pack Noopel Home Security Sensor Burglar Anti-Theft 120DB Alarm with Batteries Included - DIY Easy to Install (2)

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.

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!

The media could not be loaded. They are great for whatever you need to make sure is shut. However, it's not ideal for say a reminder to close the baby gate that people just walk through and leave open Every. Single. Time. They. Go. Through. The. Thing. because in the time it takes to open the gate and get through the BLARING SIREN you've completely lost all of your senses and suddenly you can't think straight and have hearing problems for the following hour after.... It is offensive, and rude the volume of it. Even 5 layers of duct tape can't dampen the ungodly screeching this thing produces. The sticky part holds very well. It looks nice. Works as you'd expect, aside from the deafening scream from the alarm. Needless to say the gate never opens anymore and I'm pretty sure people would figure out 100 different ways to get on the other side before they would ever want to hear that thing go off again. Definitely will work for security.I am returning this product due to us all having hearing loss now and my poor cat, I haven't seen him since putting it up.

I am 90 yrs old and live by myself in a RV. THERE IS ONLY ONE DOOR WITH A VERY GOOD DEAD BOLT. The door would have to be sacrificed to open without key. should a emergency COME occur.So that emergency aid could get in. I have elected to leave door unlocked at night, with this alarm installed on door. My bedroom is located about 30ft from door, and would surely wake me up. or in the case of my calling for help I would advise that the door was unlocked for entry.In the event of a unexpected entry, the alarm is so loud it sould supprise the intruder, as well as give me plenty of time to defend myself with my weapon of choice. I survived the KOREAN WAR, and can still handle my firearm. I still go to the firing range with my HIGHWAY PATROL GRANDSON

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.UpdateThe 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.
