1. Product Introduction

The intelligent door/window contact alarm adopts a split magnetic induction sensor design, which judges the open/closed status of doors and windows by sensing magnetic field changes. Once a status change of doors or windows is detected, the device sends alarm messages to mobile terminals and the computer-based central management platform through 4G/NB-IoT IoT, together with voice call and SMS notifications.
