Elle fait le job, la base sonne faiblement mais accompagné de sa sirène ça devient insupportable donc parfait. Les éléments sont bien reconnues, on peut facilement en rajouter.Le manuel est en anglais mais le vendeur n'hésite pas à vous envoyer un message de remerciement avec le manuel dans notre langue. Il me l'a fait pour les deux alarmes acheté avec un écart de plus ou moins 7/8 mois.L'alarme d'avant (pg500 non dispo à la vente depuis) est toujours fonctionnelle et protège une maison qui a subit deux tentatives rapprocher de cambriolage, depuis plus rien.LA caméra est cher, si on regarde son prix à la vente seule c'est 39€, alors qu'il y a des marques bien connues qui sont dans les 20€, mais elle fait le taf, je préfère la laisser fixe avec la détection de mouvements humains mais sans suivis et prendre la main pour voir ce qui se passe.Les élément d'ouverture de portes / fenêtres sont classiques, j'ai pu en ajouter d'une autre marque. Les détecteurs de mouvements sont incompatibles avec les animaux, mon chat fait sonner l'alarme, au moins on sait qu'elle détecte de loin, elle doit avoir une détection de 8/9m.Le branchement est ultra simple, attention cependant à la connexion wifi, c'est du 2.4ghz, faut parfois faire une bidouille dans notre box pour l'avoir. L'installation de l'application et le paramétrage de celle-ci est simplissime.je recommande. ### ⭐⭐⭐⭐⭐ Sicherheit *by on Reviewed in Germany 28 March 2024* Sicherheit für kleines Geld.Die Installation ist einfach, das Einrichten einwenig Geduld bedürftig, da die Beschreibung nur auf Englisch ist. Im ganzen sind wir sehr zufrieden ### ⭐⭐⭐⭐⭐ Excellent value for the price, easy installation, no issues *by on Reviewed in Germany 12 April 2024* The option I got had all the accessories, they came preconfigured and ready to use. I recommend installing the tuya app in your phone/tablet and creating an account first, then when you setup the wifi in the alarm system, the tuya app will automatically identify and add the system to your account (if both your phone and the alarm are connected to the same wifi network)The sensors, rfid tags and remote controls work very well: I decided to use mostly the tags, not tu have a chunky remote on my keychain.Arming or disarming the system can be done from your smartphone, or by touching the tag on the console's sensor, and a countdown (customizable) will start before the system is fully armed. Then you can exit your property during this countdown (I set it to 45 seconds) and the system remains armed. The same by entering or returning home: once you open a door, the triggered countdown starts (also customizable, I set 30 seconds) and you simply make contact with the tag to the console's sensor to disarm the system.The included loudspeaker is really loud, the anti-tampering system works well and there is a wifi camera included, but that one I have not yet used....The system can remain operational without electricity, but only for a few hours. Also, the function to make a phonecall or send an sms looks very interesting, however I have not tried it yet. It requires a SIM card with enabled calls / sms.When the alarm system is armed, it will be triggered by several events:- door/window sensor opening- motion sensor triggering- electricity interruption (alert on your phone)- tampering (removing parts, like dismounting the console or unplugging any cable)- wired fence interruption (untested by me)- motion detected on the camera (untested by me)-manual trigger by pressing the SOS button.Very recommended, easy to install and to use. ## Frequently Bought Together - LWOHSI Home security system, wireless 1080p surveillance camera alarm system with 120dB alarm siren compatible with Alexa Google - Outdoor Solar Siren Alarm Siren with Light Function LED Flashing Wireless Outdoor Siren 433MHz Compatible with Dadvu PG103; PG107; PG108 (PE523) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/679034596-lwohsi-home-alarm-system-gsm-wifi-professional-home-security-systems](https://www.desertcart.sg/products/679034596-lwohsi-home-alarm-system-gsm-wifi-professional-home-security-systems) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-28*
