Hendun Door Alarms with Remote, Window Alarm for Kids Safety, 1 Pack

These ARE LOUD!! They definitely get the job done. Easy to use. They are peel and stick; however also come with little screws, so you have options on how to install. The instructions were quite clear and we had them set up in a few minutes. The biggest take away I cannot stress enough, they are loud. The remote lets you adjust the volume though. They are definitely worth it. They also don’t take up a lot of space and aren’t super noticeable where we placed them. We didn’t use the screws and our front door gets a lot of traffic and the peel and stick adhesive has been absolutely fine. I think maybe the only thing people may find to be an issue is possibly with placement. Our back door the frame didn’t allow for a proper alignment, but it was close enough that it still works without issue. The lip of the frame didn’t fit the width of the magnet without knocking it off when the door was opened. We moved it to on the actual door frame and even though it doesn’t line up like the one in the photo (our front door), the magnet is strong enough that it works still. It’s one top left hand side of the door.

This product is loud and very easy to install

This is the only door alarm so far that is skinny enough to fit in our small door jam area (the door is surrounded with thick wall) and I’m glad it is because having the remote really makes it better than most . Without it the neighbors would just get used to the sound going off and it would alert people we are leaving . The other great feature is it continues to sound the alarm for 30 seconds when the door opens, even if the door is closed , unless you have the remote . Our camera has a slight delay, but even if the delay is 15 seconds , it will still catch the alarm going off for another 15 seconds , which is great. The only issue we have is that it only comes with one remote , and there doesn’t seem to be an option to purchase another one separately. I wouldnt necessarily Take a whole star off for that, except now I have To make sure to be home before my fiancé if I’ve set the alarm , which means we’re gonna have to buy a whole additional set for just the remote and hope that pairs with the original alarm. Because of that I guess I’ll take a star off . Otherwise we really do love how well it works, fitting in place, the tape works well, the remote is great and the fact that you need it to stop it from going off is even better . It’s loud enough but not so incredibly ear piercing that setting it is uncomfortable. And I should Mention when I first Got it there was no battery for the alarm itself , although the remote had batteries. I tried some old AAA and it seemed like it would only chirp instead of setting the alarm off , but , when I put Fresh ones in it worked perfectly fine . Update : I ordered Another one simply so that we would have 2 remotes because without the second remote it renders it practically useless since I cant Arm it unless I am The first to return home . It was a bit difficult to understand the instructions on how to synch the new remote to the original alarm and it took a bit of time, but I got It done. I dont Know how we would use the second alarm now because that would also require a remote of its own, and I think This is a major oversight . Aside from that we are very happy with how it’s worked so far. I’m not yet fully accustomed to having it though and have forgotten it was set numerous times which led to awkward scrambling and dropping my things and knocking things over but that’s a me problem lol not a product problem.

I tried out a few different options for a DIY home alarm system and these were the ones that absolutely fit the bill. I started out with a pair of them to test out and ended up buying 3 more sets. Why? 1) Extremely easy to set up. There is a little give in the space needed between the magnets and the actual alarm, so if your windows/ doors and frames aren't flush, no problem 2) Range! I can arm and disarm the units in my basement from my second floor. I was very surprised and happy about this! 3) Compatibility of components- I had to watch a Youtube video to learn how to do this, but it turns out, you can pair every single transmitter to work with ALL the alarms, and ALL transmitters can be paired to activate every single alarm. 4) Abundance of key fob transmitters. Every alarm comes with a transmitter so everyone in the family can have one that works the same as the next 5) Panic button: because I can activate the alarms from such a long distance, I use one of the transmitters as a panic button in my bedroom. If I hit the "lightning bolt" button, I can get ALL the alarms in the entire house to go off together. If that doesn't scare the $%#t out of an intruder, then nothing will. 6) Doorbell function: you can set the alarms to give off a double ring, just to alert you when someone opens a door or window. It's pretty loud, but would be good if you're outside or in the basement and want an alert of this kind. 7) Cost: I paid a lot more more for a lot less when I first started testing out different components for my home security. I returned the others after I saw what this system could do. 8) Power: I like that they run on batteries, so if power gets cut, they will still work. Cons? No internet alerts when your system gets set off. This is a real time, intruder focused system, not a monitoring system (so no monthly fees- another pro). To address this, I also bought a couple of Reolink security cameras to provide eyes into my home. They alert me if motion is detected inside the house. Because it has 2-way audio, I should be hearing a hell of a racket if someone actually gets in. Anyway, I am very happy with the synergy between these two systems.

I had actually bought a two pack for our Office. We moved temporarily into a model apartment on our Property while our heavily secured Office is undergoing a major remodeling. I needed something to secure our model/office, Keeping in mind that it is only a temporary move (the contractors say 2 months, so I'm expecting 4.) A hard wired system costs upwards of a few hundred dollars plus a monthly monitoring fee, definitely not worth it for our circumstances. So I bought these and they are amazing! They installed in a few minutes and it only took another few minutes to program the remotes to Work with the entire System. Now when we lock up, from outside the apartment, we click the remote one time to set it and that's it! These alarms are incredibly loud, will definitely scare Away any thieves looking to steal from us. They are only taped so they'll remove Fairly easily, I assume with a little solvent to remove the adhesive, but the double sided tape that came with it seems Pretty tough to last. I liked these so much that I ordered another pair for my front door and sliding door in our apartment!

Small magnetic senor has 2 small screw holes for mounting or use double-sided tape, the larger Alarm sensor has no screw holes for mounting and need to use Double Sided Tape (included). Does not include AAA batteries as each requires 2 or total of 4 batteries. The Remote must have a watch/calculator battery inside as I did not need to insert/install any battery. The Siren alarm is very loud and continuous as the Door Chime is half as loud and sounds like the small ringing/chime you get when entering a Small store. Read that these Door Alarms will drain the AAA batteries in less than 2 weeks. The Remote control has 4 functions as in Lock, Unlock, Siren, and Bell. On "Lock"/Off "Unlock". Need to place the Remote Control unit in a safe and inconspicuous place. The Remotes are not Labeled so you may want to. Currently using the Door Chime setting because the Siren can wake up everyone in the household or if you reside in an Apartment complex will annoy your neighbors. If alarm is triggered in an apartment and no one home able to turned it off, nice way make your neighbor angry and want to bust your door down. Only have used it for 1 day, and No False Alarms - going off by itself. Will need to keep tabs because said it may drain the AAA batteries rather quickly. A set for $26 is cheap. Hopefully they will work for a couple years or more. Otherwise, may need to spend a few Hundred Dollars and pay out for a Security System with alert notification like ADT. All depends on your needs and valuables trying to prevent theft.

Triple AAA batteries are used in unit not weird LR44. However that is what remote uses. Have not accessed remote batteries. This is a loud alarm which is useful. You cannot adjust volume.So if you have babies and you need to disarm alarm it is loud to disarm. I have no babies to worry about. See pictures for mounting help. My door FRAME is rounded molding. Attach the function unit on the flat door and the the small receiving unit on the rounded frame. I gave three stars because one unit continually flashes even when disarmed. The batteries drain within a week. I couldn't find any contact info for the company so I am stuck with this defective unit. The other one is fine. I like the remote function. I can arm and disarm without having to reach high every time. But quality is lacking. You will see in pic that I have placed a magnet under the door unit. This door gets slammed a lot and adhesion was a problem until I added this magnet support. I have changed my review after Hendun reached out to me saying my unit was still under warranty. Very happy about that. They have solved my issue. Thank you Hendun.

We live in apartments and this is great for our sliding glass door. The alarm is loud when you arm it so you know it’s turned on and it’s loud if the alarm is triggered. Easy to set up

I purchased this alarm for my sliding door. It works so well - very loud! My grandchildren are between the ages of 2yrs - 7yrs. We have an inground pool in our backyard. This alarm gives us a peice of mind, although we are still very protective of/watch the kids closely when they come over. Thank you, Katherine Soulliere

Ich habe diese kleine Alarmanlage von innen an der Tür meines Kellerraums installiert, da dort unsere E-Bikes drinnen stehen. In einem Mehrfamilienhaus möchte man einfach etwas zusätzliche Sicherheit haben, besonders weil es leider immer wieder zu Kellereinbrüchen kommt. 🔧 Montage & Installation: Die Installation ist kinderleicht. Alarmanlage und Magnet werden mit den beiliegenden Klebepads an Tür und Rahmen befestigt. Danach einfach zwei AAA-Batterien 🔋 einsetzen, schon ist das Gerät einsatzbereit. ⚠️ Wichtig: Die Pfeile auf Alarmanlage und Magnet müssen zueinander ausgerichtet sein und sich gegenüberstehen. Der Abstand sollte idealerweise wenige Millimeter, maximal 1 cm betragen, damit der Sensor funktioniert. 🎯 Bedienung: Die Aktivierung und Deaktivierung der Anlage, erfolgt über die selbsterklärende Fernbedienung. Der Alarm lässt sich so bequem ein- und ausschalten, was im Alltag besonders praktisch ist, zum Beispiel bei häufigen Kellergängen. Allerdings ertönen bei jedem Aktivieren oder Deaktivieren der Anlage laute Signaltöne an der Anlage, während gleichzeitig eine Signalleuchte an der Fernbedienung aufleuchtet. Persönlich hätte ich mir gewünscht, dass nur die Signalleuchte funktioniert, ohne dass zusätzlich ein Alarmton ausgelöst wird. 📢 Lautstärke: Der Alarm der Anlage ist wirklich extrem laut. Wenn er ausgelöst wird, hört man ihn meiner Meinung nach im ganzen Haus. Genau das wollte ich erreichen, so wird sofort Aufmerksamkeit erzeugt und ein möglicher Diebstahlversuch wird wahrscheinlich schnell abgebrochen. ✅ Fazit: Für meinen Zweck, den Kellerraum und unsere E-Bikes zusätzlich zu sichern, erfüllt das Gerät seine Aufgabe sehr gut. Einfache Montage, sehr lauter Alarm und unkomplizierte Bedienung. Preis-Leistung passt aus meiner Sicht ebenfalls. Ich würde die Alarmanlage wieder kaufen. Von mir eine Absolute Kaufempfehlung 👍

Der HENDUN Kabellose Türalarm hat meine Erwartungen voll erfüllt. Die Installation war kinderleicht und in nur wenigen Minuten erledigt. Man muss lediglich den Hauptalarm und den Magnetsensor an Tür oder Fenster kleben – ganz ohne Bohren oder aufwändiges Kabelverlegen. Das System war sofort einsatzbereit. Die mitgelieferte Fernbedienung ist sehr praktisch. Man kann den Alarm einfach scharf- und unscharf stellen, was im Alltag sehr komfortabel ist. Was mich besonders beeindruckt hat, ist die Lautstärke des Alarms – mit über 100 dB ist er wirklich ohrenbetäubend und schreckt potenzielle Eindringlinge effektiv ab.

La alarma funciona bastante bien, tiene un sonido fuerte, lo unico que no me agradó mucho es que la alarma deja de sonar si vuelves a cerrar la puerta o ventana. Una de las alarmas venia con parches de pegamento viejo (tuve que retirarlos con calor y ponerle nuevos) pero en general cumplen con la función de "alarmar" y que se percibia la alarma en toda la casa.
