Remote temperature monitoring

Monitors the temperature,
notifies in the event of deviations


Mobeye ThermoGuard

The Mobeye ThermoGuard is a reliable detector for temperature problems. In an alarm situation, it sends notifications via push message, telephone call, SMS or e-mail.

Monitors the ambient temperature on
exceeding or falling below the set limits.

The Mobeye ThermoGuard aims to prevent damage by early warning of temperature deviations. Set the minimum and/or maximum temperature limit and let the Mobeye ThermoGuard monitor the ambient temperature. Can operate fully battery powered.

This product is the successor of the Mobeye CM2200.

Temperature measurement

The temperature sensor is digital and extremely accurate. The minimum and/or maximum temperature limit is adjustable between -35 °C and +70 °C. The sensor is factory calibrated and indicates the value in decimal.

Alarm messages

In the event of an alarm, the Mobeye ThermoGuard sends alarm notifications by app (IOS/Android), telephone call (voice message), text message and/or e-mail. The message includes the actual temperature. For the push messages there is a choice between an escalation plan or group message. With the escalation plan, the recipient can confirm the push message, so that the other contacts no longer receive the message. If none of the recipients confirms the push message, a phone call is made. The number of contacts is unlimited.

External voltage vs battery powered

The Mobeye ThermoGuard can run on batteries for a long time which makes it independent of an external power source. Optionally, a mains adapter is connected (12-24V DC). In this case, the power supply is also monitored. If there is outage, a message will be sent. The internal batteries ensure that the alarm dialer continues to work for a long time. The ThermoGuard will continue to monitor the temperature limits and input contacts and will still report alarms. Once the power restores a notification will be sent.

Potential-free alarm inputs

In addition to the temperature sensor, the Mobeye ThermoGuard (CM4200) has two NO/NC inputs for connecting alarm contacts and sensors. These can be used for monitoring the status of a make/break sensor or device, such as an air conditioner or door magnet.

Network and SIM card

The Mobeye SIM card gives the device full functionality, including the use of the Mobeye Internet Portal and the app. With the Mobeye SIM card, communication takes place over the 4G LTE-M network with 2G as fallback.
When you insert your own SIM card, the device works on 2G. Alarm messages are then sent via SMS and/or call to max. 5 telephone numbers.
