24pcs Wireless DIY Home Burglar Alarm System, 4G WiFi GSM, No Monthly Fee,Home Security with App Alert

One of my best purchase from Amazon. My neighbour recently got robbed while he was not at home. After knowing that, I decided to install an alarm system along with cameras. When I enquired with alarm company, I have to pay monthly for there service and equipment. I am a DIY man myself. Eventually decided invest in a modern alarm system. I am very happy and satisfied in buying and installing this alarm system myself. The device very good. Enough sensors for a 3 bedroom house. Very easy to setup. The SIM card feature makes it’s the best. Now I leave my house with a peaceful mind assured about its safety. So far it’s been nearly a month and no issues with the device. I recommend it !

Excellent for such a low price. The instructions are written in finest Chinglish and border on incomprehensible. However, there are lots of videos on YouTube showing you what to do. Once you understand the way it works, programming commands make sense and are easy to handle. It is not programmable remotely by SMS as with our predecessor alarm but a limited number of commands can be done by phone using your phone's DTMF keypad. The standard audible alarm is - inaudible. If you want a loud Woo Woo, you will need to buy that option separately. Given that public usually ignores the audible alarm anyway, this is not great problem as the unit will text AND phone you when triggered. The remote radio plips struggle to communicate with the control unit if that unit is sited too far from the exit door of the building. The batteries supplied for the wireless PIR's and alarm triggers run flat in an instant - once fitted with Duracell replacements, you get around 3 months out of them.

Had one for several years but I moved house and had to get another and was happy to buy the same again. It works very well and is excellent value for money. I don't think the manual is as bad as some others say, but there are some helpful videos on youtube if in doubt. One thing I did find is that on mine, when you start to pair a device it says something like "pairing device" then you pair the device and it again says "pairing device" rather than saying "device paired", so you get angry trying to figure out why it hasn't paired when in fact it has. I notice that this is not a problem on the youtube videos so I think I have a different, slightly messed up version of the firmware. Don't let it put you off though.

Crap

The alarm system seems to work ok, and once you uderstand the setup procedure, its easy to add sensors. But there are problems with this alarm. 1- if you add external sounder it chirps when activating or de activating alarm. Not good late at night. 2- its does not keep good time, always wrong. 3- the remote fob buttons are not marked correctly, the at home activation button is marked wrong, and when pressed it activates the alarm, the panic button is the activate alarm when at home. 4- the external sounder is not loud enough. Small changes would have made this aolarm a lot better.

Very pleased with this alarm.

Hey, i purchased this, and installed it today. First issue, you need to have your wifi in 2.4gz not 5gz. That's not a problem for some, you have to access your router as an admin, change the setting, and when it's all set up, change it back again and the alarm system will still work. The instructions are very vague. It took me a while to add the host panel. Also for example, nothing to tell you how to turn the PIR Motion detecter hardware on. And I winged it to connect each one. (You need to name them, so you know.) Also, change the door sensors in the app to that. Once I started to get the hang of it, it all fell in to place. My only moan now it's all up and running is the outdoor siren, that has to be wired to the control panel, means you can't have the control panel by the front door, as the wire for the siren is so short. So I have my control panel at the top of my stairs, the siren out the window. The remote control turns the alarm on and off. 4 out of 5 stars. It could be better, and have an outside box to show people there is an alarm and the siren within it. Hope this helps. 140 quid. Worth it!

Good product for the money easy to install

We wanted to have some semblance of a alarm system for our warehouse space but didn't want to pay the expensive monthly paid alarm subscriptions plus installation and so forth. The physical look of it and alarm is a big enough deterrent and that there's a built battery will ensure it works even without external power. Just like a paid system, this is essentially the same thing just without the monitoring and external alert - basically you do the monitoring and contacting authorities instead of paying the monthly fees. To get as close to those abilities as possible, you'll want to make use of either the 2g or 3g capabilities by getting a sim card - after some shopping around I was able to find one for under twenty dollars a month. Initially we were just going to buy individual, single door and window sensors and have them work independently. However, we figured for not much more it was better to have all of them at least linked to a central single system and a better investment overall, not to mention ease of use. Installation was straightforward enough and simple if you're decent with basic hardware installation as everything is pre paired, so it's more or less plug and play (install and play rather) out of the box and consequent app setup. For a warehouse space where hidden wires aren't of the upmost importance it's even easier. Entering and exit method of use is just like the monthly systems and the set of four remote controls is a nice touch making the unit more modern and convenient to use. Our space covered is around two thousand or so square feet so it should have no issues covering somewhere near that, although it'll depend on your area's configuration given the number of sensors. All in all a great, simple do it yourself and cost effective alternative to monthly subscription alarm systems.

Ottimo prodotto, funzionale, facile da installare. Ho acquistato anche la sirena wireless, che può essere installata all'esterno, a completamento del sistema di allarme. Ho ricevuto un'ottima assistenza e disponibilità da parte del produttore. Ottimo rapporto qualità prezzo. Sicuramente consigliato

Our granddaughter is at that age where she likes to explore everything inside and out whether mom and dad are asleep or awake. My stepson and DIL were at their wits end. I remembered my sister had sensors when her kids were young that would go off whenever a door or window was opened. So I started looking for a set that did that, but everything I found were complete security systems. So I thought, well, a little extra security isn't a bad thing. This comes with a main unit, a wired siren, 5 motion sensors, 12 door and window sensors, 4 remotes, and a power supply. I was actually surprised at how affordable it was for everything it comes with. The primary reason for choosing this system was the 12 door and window sensors. Now when our granddaughter tries to "escape," I mean "explore," mom and dad hear the alarm and get notified. They used the motion sensors near the doors and the hallway just outside her room. This way they know when she's coming and going from her room, but also, if a sensor doesn't catch her, there are several backups in various places. Another reason I chose this system was that it was wireless. There was no drilling or having to open walls. The installation was easy and straightforward. The built-in battery means that even if the electricity goes out, the system still works. You can even use the system to call emergency services. Another neat feature is that you can set a timer to turn the system on or off and even set it to bypass certain sensors. Overall, it's a good system that is affordable. The most important part is that it keeps our granddaughter safe.

GSM alarm system works as described. It does take effort to set it up. Without the SIM card the system still works but not making phone calls. The alarm is working and is loud enough. It comes with all the accessories. I compared the price and found this one is lower with good value. Remote control adds convenience. I like the build in battery which can run for about two days. Overall solid product with some learning curve to get it working.

Bon produit que j’ai acheté pour un neuf mais à déjà été utilisé . La centrale présente des griffures , les boîtes des détecteur sont noté au stylo comme appartenant à telle ou telle fenêtre par son ancien propriétaire . Certains détecteur sont déjà en service avec pile et reconnus pas la centrale sans avoir à les installer . Pas très honnête comme procédé !
