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.

Maximize network uptime and equipment lifespan

Real-time visibility and alerts give you control over your environment. Ensure optimal conditions and minimize risk with remote monitoring and flexible alerting.

Gain value in less time

Quickly provision and manage thousands of sensors to monitor temperature, humidity, leaks, and intrusion. Simply insert the batteries and add to the dashboard. MT sensors automatically connect to existing MR and MV devices. Say good-bye to on-premise servers, dedicated gateways, and management software.

Drive smarter decisions through data

Understand trends about your physical environment. Improve safety, security, and operational decision-making through a data-driven approach. Build on top of the Meraki platform using APIs or the vast ecosystem partner community and further enhance operations.

Secure IoT devices seamlessly

Each Meraki MT sensor features a Trust Anchor module (TAm), which securely authenticates the device and encrypts all communication with the sensor gateways. Combined with automated firmware updates, Meraki MT sensors pack a powerful security punch in a smart package.



Centralized cloud management

The Meraki dashboard provides secure monitoring and management of all your Meraki products-from MRs to MVs to MT sensors-from anywhere in the world.


Flexible alerts

Set customized thresholds for devices and receive alerts via SMS, push notifications, email, or use webhooks to connect to your platform of choice.


Automatic Bluetooth connectivity

Using 2.4 GHz Bluetooth Low Energy (BLE), sensors automatically connect to MV and MR devices in the same network.


Seamless setup and installation at scale

Wire-free installation, flexible mounting options, and automatic pairing makes it easy to provision thousands of sensors in a short amount of time.


Onboard storage

Five days of onboard storage keeps data safe in the event of an outage.

icon_Long battery life

Long battery life

Field-replaceable AA batteries, with up to five years of battery life, provide one less thing to worry about.


Open API

Automate analysis outside of the dashboard, link to third-party services, and aggregate MT data with information from other business systems.


Secure and always up-to-date

Trusted Anchor module (TAm) enables a secure key to exchange data between the gateway and sensor. Automatic firmware updates keep things running smoothly.
