Product description






Multi-Functional Host: The Home Alarm System host supports 10 international languages, features emergency call and doorbell functions, is compatible with more Tuya devices (such as cameras and smart switches) for connection, and allows custom naming of different defense zones.
High-Decibel Real-Time Alarm: No concern about not hearing the alarm due to long distances. Equipped with a separate 120dB siren, the system also sends mobile APP alerts at the same time, deterring unauthorized people promptly and enabling quicker responses.
Strong Expandability: You don’t have to worry about incomplete coverage due to a large house area. The PGST Alarm System allows for additional sensors to be added, ensuring more comprehensive protection.
Multiple Communication Connections: The Home Security System supports WIFI, GSM, 4G, and GPRS connection methods—there’s always one that fits your needs, providing more reliable support for your home arming. (Note: Only 2.4GHz WIFI is supported; 5G is not compatible.)
Low Battery Alarm: When the battery level of the Alarm System host or other sensor accessories is too low, an alarm will be automatically triggered. This allows you to recharge the devices in a timely manner, facilitating better maintenance of the system.
Multiple Control Methods: Supports four control options—Tuya APP, Alexa Voice Control, Host Operation, and Remote Control. These diverse methods adapt to different scenarios and personal preferences, making arming/disarming more convenient and straightforward.

Works great!
Ok overall this works well. However I struggled with the installation and instructions. However my back up help seemed to get it just fine and have it working well, within like 30-40 minutes.Once installed everything worked smoothly and I’m very pleased with the product.However if you have adhd or just suffer from long winded instructions maybe call in some back up!

Perfect Starter Wireless Home Security Kit
This quality kit comes with all the necessary items to make this the perfect starter kit for wireless home security and includes the interface control panel, siren / noise alarm, 2 window / door separation sensors, 2 motion sensors, 2 access fobs, and 2 remotes (used for quick lock and unlock of the system), and USB-C charger.The main interface unit is wall mountable and all items are super simple to install and can be installed as simply with double-sided stick tape. Instructions are included and my device came powered sufficiently to setup with ease and with zero lag time.

Smart Compact Security System
This alarm system can completely cover my house, providing excellent protection for every window and door. Even if there aren’t enough sensors initially, additional sensors can be connected. I like its full touch color screen, which allows for direct and intuitive operation. At the same time, app remote control and intelligent voice control make managing the system more convenient and hassle-free.

Stable Operation, Stylish Appearance
I like the appearance of this home security system – it’s very simple and elegant. The quality is excellent, providing long-lasting and stable operation. The door sensor alarm and motion detector have been very helpful because I have several cats and dogs that always try to sneak out from time to time. It alerts me promptly every time, and I can control it through a voice assistant.
