The H502 GSM WiFi alarm system is a complete smart security kit for a house, apartment, office, shop, garage or small business area. It combines a modern 4.3 inch touch panel, GSM and WiFi communication, mobile app control and a set of wireless sensors prepared for everyday protection.

Instant Alerts in Three Ways

When the system detects an intrusion or another important event, it can notify you by phone call, SMS and mobile app alert. You can define up to 5 phone numbers, so important information can reach you or another trusted person even when you are away from the property.

Remote Control with GSM and WiFi

Control the alarm from your smartphone using Tuya Smart, check the current status, arm or disarm the system and receive notifications wherever you have network access. GSM support gives an additional communication channel when WiFi alone is not enough.

4.3 Inch Touch LCD Panel

The central unit is equipped with a clear 4.3 inch color touch screen. It is designed for intuitive daily operation, fast access to the most important functions and convenient configuration directly from the panel.

Practical Protection for Several Zones

This version includes 10 PIR motion sensors and 4 wireless door/window opening sensors, allowing you to protect entrances, corridors and selected rooms from the start. The set can be expanded with additional compatible accessories when your needs grow.

Polish Menu and Multilingual Support

The system offers voice prompts and interface language options, including Polish and other popular languages. This makes installation and daily use easier for family members, employees or anyone who needs simple control without complicated instructions.

Automatic Arming and Disarming Schedule

You can set schedules for automatic arming and disarming, which is useful for routine protection during work hours, night hours or times when the property is usually empty.

110dB Wired Siren and Backup Power

The included wired siren gives a loud sound warning to discourage intruders and alert people nearby. The built-in backup battery helps maintain protection during a short power interruption.

Expandable Security Configuration

The H502 platform can be expanded with compatible sensors, remote controls, RFID accessories and sirens. This allows you to build a setup adapted to the size and layout of your property.
