What’s not to like?
This alarm has everything you need to protect your property. I have mine in set up in a large garage and as well as protecting that, I have also have a summerhouse. I’ve used PIRs in both structures and all doors are fitted with sensors too. The alarm is permanently connected to mains via a usb plug and I have WIFI within the garage so setting everything up is a doddle. The system works as it should, when armed to away it protects both buildings, and I have set it up on the mobile phone using the Smart Life app so the summerhouse can be used even if the garage is armed by using the Home settings. The system can be programmed to call your phone if you install a GSM card, or in my case, alerts are send to my mobile using the WiFi, which works wherever I am. Arming and disarming can be set to work automatically using 24/7, delays can be set when leaving and entering. The alarm has an anti-tamper on the rear so if it is removed from wherever you screw it to the wall, the alarm goes off. Alarm time can be changed in the menus but I would advise around a minute. The siren supplied is deafening. Even without it being plugged in, the audio from the alarm is loud enough to make people aware it has been triggered. Bonus of PIRs, door sensors, remotes and fobs all available to purchase if you require more than the kit has, even though there are 2 versions and I went for the one containing less. Many have said about the battery dying after a short time, and I haven’t had the chance to test this but during the set up it was unplugged and running on battery only with no issues, so probably about 2 hours. To summarise, the alarm is cheap but good quality. It has many features and extras/spares easily available. It does exactly as you expect it to. It’s easy to install. The instructions are basic but easy to find information on YouTube if you have difficulties. The seller also has good communication if you have any problems. Delivery is quick and item is well packaged within its box. I’d give it more than 5 stars if I could.

incorrect information
first of all it says no monthly fees but to send/recieve information they want money ? one of my motion sensors is faulty it does nothing not even switch on the unit decideds to arm or disarm at any moment with no input from me the battery life is 8 hours and it wont connect more than 5 sensors even though it says 100 ,not worth the money in my opinion

Easy to use and set up BUT...
It's a good system, very easy and fast to install, it's easy to use and set up, I even have it on my garden gate BUT I've taken 3 stars off as I can't work out how to set the password meaning ANYONE can disarm the alarm simply by pressing 'disarm' without needing to input any security code or anything! I have the password set to on but it still doesn't need it to disarm! This feels incredibly counter intuitive as surely that would be the FIRST thing a potential thief would try pain hearing the countdown.... Maybe my suit is faulty I don't know but it doesn't seem right 🤷♂️

A reliable internet connection is a must
Easy to install and set up. Hopefully its a good buy, not had it long enough to test its reliability and response to the alerts

Minor niggle
Good system EXCEPT tested every sensor individually and renamed them to suit, several come up on triggering as something different e.g. motion sensor in porch comes up as bathroom window!

Diese Alarmanlage ist echt super und war auch leicht zu installieren. Die Sensoren überall angebracht, die Sirene und Transponter funktioniert einwandfrei. Auch die App dazu funktioniert tadellos, und man wird benachrichtigt wenn man nicht zu hause ist. Haben alles überprüft ob es klappt, und es war alles zu unserer vollsten Zufriedenheit. Kann ich nur empfehlen.
