The MT20 open/close sensor detects intrusions, protecting access to critical infrastructure or assets.


Managing security and monitoring access for physical spaces has always been an important consideration for organizations. By tracking changes in the physical environment, businesses can minimize vulnerabilities, prevent disruptions, and ensure stronger security.

The MT20, part of the Meraki MT sensor family, provides insight into access to the physical environment. Using magnetic fields to determine positioning, MT20 can detect when doors are opened or closed, allowing organizations to detect intrusions and understand usage trends.

Simple sensors.
Powerful Meraki platform.

The MT20 sensors are quick and easy to set up and can be installed on doors, gates, cabinets and more. Once powered on, MT20 sensors automatically connect via Bluetooth to Meraki MR access points or MV smart cameras, eliminating the need for a separate gateway. Powered by the Meraki platform, MT20 sensors provide real-time monitoring and alerting, allowing organizations to detect intrusions and understand access and usage trends.

Whether it’s knowing when someone enters a restricted area, keeping track of doors left ajar, or simply understanding how many individuals enter through a back entrance, the MT20 sensor provides the visibility and data to better support business decision-making across the board.

    That might be worth up to about 5% to you.

    We can email you a quote same day, but it might take a couple of days to confirm the details. We WILL need the details of the end user of the purchase if that isn't you. We won't contact them, though!

    So if you have the time, you might want to ask MerakiStore for a quote instead of checking out today.
