## Long description

Hikvision MGD-300 is a compact wireless glass break detector designed to monitor acoustic signatures of glass impact and fracture. The sensor detects breaking of plate, tempered and laminated glass within a detection distance of up to 6 m and transmits alarms over the 433.05–434.79 MHz band. Powered by a single 3 V CR123A battery and housed in a slim enclosure (111 × 28 × 25 mm), the device is intended for integration into alarm systems to protect windows, display cases and glass doors in residential and commercial premises.
Advantages
The MGD-300 offers multi-frequency signal analysis to distinguish true glass-break events from ambient noises, reducing false alarms in typical environments. Stepless sensitivity adjustment allows precise tuning based on mounting position and glass type, while a test mode simplifies commissioning and alignment. Built-in tamper detection notifies the control panel in case of device removal or enclosure opening. The compact dimensions and wireless operation support flexible placement without cabling constraints.
Suitable for
Securing residential windows and balcony doors
Protecting retail display windows and shopfront glass
Monitoring glass partitions and interior glazed doors in offices
Covering exhibition cases and showcases in museums or galleries

How to use
Mount the Hikvision MGD-300 on a stable surface near the protected glass so the sensor faces the pane within the specified detection distance. Adjust the stepless sensitivity while in test mode to achieve reliable detection of breaking events for the specific glass type and mounting position. Insert a single CR123A battery, verify wireless connection to the alarm control panel and perform functional tests to confirm alarm transmission and tamper signaling. Follow the alarm system manufacturer’s integration procedure for enrollment and zone configuration.
Usage recommendations
Place the detector at an appropriate distance and orientation relative to the glass, avoid mounting on vibrating or loose surfaces, and use the test mode during setup to fine-tune sensitivity. Replace the CR123A battery at regular intervals according to actual usage and the alarm system’s battery status reports to maintain reliable operation.
