As part of the CoWork Series, this magnetic switch is particularly suitable for safeguarding doors and windows against unexpected entry, making it ideal for use in homes, offices, and other sensitive areas.

Equipped with advanced technology, the WS301 detects opening and closing events of doors and windows, effectively alerting users to any intrusion or unauthorized access. This feature is crucial for maintaining security in both residential and commercial settings. The device also includes a tamper detection functionality, which promptly alerts administrators to any attempts to dismount or tamper with the device, ensuring enhanced security measures.

Additionally, the Milesight D2D (Device to Device) communication protocol featuring LoRa® enables efficient communication among different Milesight LoRaWAN® node devices without needing a LoRaWAN® gateway.

The device boasts a long-lasting battery life of 4-7 years, minimizing the need for frequent replacements and maintenance. Furthermore, the WS301 is designed for simple and effortless installation, offering options like double-sided tape mounting and screw mounting to suit various door and window types.
