Description

Mobeye ThermoGuard CM4200 Temperature Detector

The Mobeye ThermoGuard CM4200 helps prevent damage from cold or overheating. By setting a lower and/or upper limit, this compact 4G device monitors the ambient temperature. The CM4200 is equipped with a highly reliable temperature sensor. As soon as the temperature falls outside the user-specified limits, an alarm message will be triggered. The device is entirely battery-powered or can be connected to an external power source.

In the event of an alarm, the Mobeye CM4200 sends alarm notifications via an app (iOS/Android), telephone call (voice message), text message, and/or email. The contact persons are set with choices for the method of alarm. These messages also provide the current temperature reading.

The Mobeye ThermoGuard can operate for over a year on a single set of batteries. A notification is sent when the battery voltage is low. When using an external power source (12-24V DC or mains), it also sends “power failure” notifications. These power failure notifications are often the first indication that something is amiss and requires attention.

Mobeye ThermoGuard, reliable and simple

In addition to the temperature sensor, two potential-free sensors can be connected, such as a failure contact or a door magnet contact. The settings are easily programmable, including temperature limits, automatic switch-on and switch-off times, alarm delay, calibration value, repeat messages, test messages, and alarm texts.

How the Mobeye CM4200 Works

The Mobeye CM4200 continuously measures temperature values. The alarm dialer promptly sends notifications if it becomes too cold or too hot, giving you complete control.

  1. Place the sensor in a location with a stable temperature, not too close to the cooling element or heat source.
  2. Configure the temperature limits and add contact numbers for notification purposes.
  3. Once the measured temperature exceeds the set limits, the ThermoGuard CM4200 sends alarm messages to these contacts. When using the portal and app, you can set up an escalation plan, including alarm confirmation.

Typical Applications for the Mobeye CM4200 ThermoGuard

The Mobeye CM4200 ThermoGuard is a highly reliable temperature monitoring and alarm system designed for precise and continuous temperature control. It provides instant alerts when temperatures exceed or fall below defined thresholds, helping users prevent spoilage, equipment damage, or safety risks. This makes it ideal for professionals who require dependable remote temperature monitoring in sensitive or high-risk environments.

Common applications for the Mobeye CM4200 ThermoGuard include:

  • Medical refrigerators, ensuring safe storage of vaccines, blood samples, medicines, and other healthcare products
  • Server rooms, protecting critical IT infrastructure from overheating
  • Cold storage areas, such as those used for dairy, seafood, meat, and wine cellars
  • Void properties, where frost or heat alarms help prevent damage in unoccupied buildings
  • Livestock sheds, maintaining optimal temperatures for animal welfare
  • Home environments, e.g. in fish tanks and aquariums, ensuring stable water temperatures for aquatic life

Using the included Mobeye SIM card? You get full access to the Mobeye Portal and app, 4G connectivity with 2G fallback, unlimited contacts, push notifications with escalation plan, and remote programming. Subscription rates at mobeye.com/en/sim-portal.


⚠️ Using your own SIM card? If you use your own SIM card, the features of the Mobeye Portal and Mobeye App will no longer be available. Alarm notifications will instead be sent via text message and/or phone call to a maximum of 5 phone numbers. Please note that not all mobile network operators support the call function, some additional security features will be unavailable, and Mobeye will be unable to provide the full range of support options. For full functionality, use the included Mobeye SIM card.
