Mobeye Frost Alert Systems: CM4200X vs CML4275

Protecting crops and outdoor installations against frost damage requires timely and reliable temperature alerts. Mobeye frost alert systems continuously monitor local outdoor temperatures and notify you immediately when critical limits are reached. Designed for autonomous operation and outdoor use, these battery-powered devices provide dependable protection during night frost events and changing weather conditions.

This page compares the Mobeye CM4200X and the extended CML4275 frost alert systems. While both models deliver accurate temperature monitoring and instant alarms, the CML4275 adds temperature trend visualisation for users who need deeper insight to support operational decisions. By outlining the differences clearly, this comparison helps you choose the frost alert solution that best matches your application and monitoring requirements.

Night Frost Alarm: Mobeye CM4200X

During the cold night, it might be necessary to protect your crops and blossoms with overhead irrigation, wind machines, heaters, or even smudge pots. But they need to be activated at the right moment. Our Night Frost Alarm alerts you immediately when temperatures drop, so you can act fast — no more staying up all night monitoring the weather.

The Mobeye CM4200X is a reliable, battery-operated frost alert designed for outdoor use, housed in a durable IP66-rated enclosure with an integrated communication module. It continuously monitors outdoor temperatures and immediately notifies users when a preset frost threshold is reached, making it a dependable solution for night frost protection.

Extended Frost Monitoring with Temperature Trends: Mobeye CML4275

For users who require more insight than a simple alarm, the extended version, Mobeye CML4275, offers additional functionality while retaining the same robust hardware platform. Alongside frost alerts, the CML4275 enables temperature trend monitoring through an online application, providing a clear visual overview once an alarm condition occurs. This allows users to understand how temperatures evolve over time rather than reacting to a single alert.

The CML4275 is suitable for year-round use. In addition to a lower temperature limit for frost detection, it allows an upper temperature limit to be set. When this upper threshold is exceeded, a notification is sent, supporting timely decisions such as adjusting foil covers or activating cooling measures during warmer conditions.

Which Frost Alert System Fits Your Application?

Both the CM4200X and the CML4275 feature long battery life and factory-calibrated temperature sensors to ensure accurate and consistent measurements. The key difference lies in data handling. The CM4200X operates purely as a freeze alarm dialler and does not provide data logging, temperature trend visualisation, or reporting. It supports a single temperature sensor and does not offer an open collector output. Apart from these limitations, its operational behaviour is identical to that of the CML4275.

In short, the CM4200X is ideal for straightforward frost alerting, while the CML4275 is the preferred choice for users who want added temperature insight and trend analysis to support informed decision-making.
