wireless

Overview
The Milesight EM300-MCS is a magnetic contact switch for door/window intrusion detection that combines security monitoring with environmental sensing. It detects open/close events, provides real-time alarm reporting, and includes built-in temperature and humidity sensors. The device is designed for long battery life, industrial-grade protection (IP67) and reliable LoRaWAN® communication with data retransmission and local storage for traceability.

Key Features

• Real-time intrusion/unauthorized entry alarms for doors and windows.
• High-sensitivity magnetic detection with 20–30 mm sensing distance.
• Integrated temperature and humidity sensors for combined security and environment monitoring.
• Customizable alarm reporting intervals and reporting schedules.
• Long battery options: standard 1 × ER18505 Li-SOCL2 4000 mAh (8000 mAh optional), multi-year operation under low-frequency scenarios.
• Industrial enclosure: IP67 rating and UV resistance for outdoor and harsh environments.
• Connectivity: LoRaWAN® (OTAA/ABP Class A) and Milesight D2D support.
• Data reliability: retransmission after network outages and device-side storage of up to 2,800 historical records for traceability.
• NFC-based configuration and power on/off via mobile app for wireless commissioning and password verification.
• Flexible mounting: transceiver supports wall screw, 3M tape and cable-tie; magnet supports wall screw and 3M tape.

NFC Configuration (wireless commissioning)

• Install the Milesight ToolBox app on a mobile device.
• Enable NFC on the phone, open ToolBox and attach the phone to the device to start configuration.
• Verify password and configure device parameters wirelessly (alarm intervals, thresholds, reporting settings).

Cloud & Integration

• Compatible with standard LoRaWAN® gateways and network servers for wide-area deployment.
• Works with Milesight IoT cloud/platforms for visualization, automated triggers, scheduled reports and mobile alerts.
• Supports Milesight D2D controller for local automation scenarios.

Installation & Use Cases

• Typical uses: door/window intrusion detection, perimeter monitoring, access-control alerts and combined environmental monitoring where door status is required.
• Installation-friendly: compact magnet and transceiver with multiple mounting methods for retrofit or new installations.
