Milesight VO-EM300-MCS Magnetic Contact Switch

Milesight VO-EM300-MCS, the LoRaWAN magnetic contact switch with temperature and humidity measurement, magnet distance 20 to 30 millimeters, IP67 

The Milesight VO-EM300-MCS is the LoRaWAN magnetic contact switch. It reliably informs you when and where a door or window is opened. The data is transmitted wirelessly via LoRaWAN to a separately available gateway and stored in the Milesight Cloud. This way, you have access to all events and statistics from anywhere. The Milesight VO-EM300-MCS also measures temperature and humidity, making it a true all-round sensor for door and window monitoring.

The Milesight VO-EM300-MCS is completely battery-powered and requires very little energy. With one battery, it achieves a service life of about five years. With a second battery, the operating time is extended to about ten years. Setup is convenient via an app using NFC directly with a smartphone. The magnetic contact has a distance of 20 to 30 millimeters and a 260-millimeter connection cable. The housing is weatherproof with IP67 protection and can therefore be used both indoors and outdoors.

The Milesight VO-EM300-MCS is versatile for use in commercial spaces, offices, hotels, shops, or private homes and vacation houses. It reliably detects every door opening and transmits the data in real time. The strong building penetration of the LoRaWAN protocol also enables reception in basements. The sensor comes with mounting material included and is ready for immediate use. With the Milesight Cloud, you can view all events online, retrieve statistics, and set up notifications if needed.

The Milesight VO-EM300-MCS is the ideal solution for smart access monitoring and indoor climate control. It combines door status monitoring with temperature and humidity measurement in a compact, weather-resistant housing. The battery life of up to ten years ensures minimal maintenance. NFC configuration makes commissioning particularly easy. With the Milesight VO-EM300-MCS, you always have full control over your doors and indoor air quality.
