Description

Mobeye CombiGuard CM4600 Boat Alarm or “ShipGuard”

The Mobeye CombiGuard CM4600 (also known as ShipGuard), is a multipurpose and multisensor 4G boat monitoring and alarm system designed for reliable protection on boats and other applications. This advanced device continuously monitors key environmental and technical parameters, providing early warnings to prevent damage and ensure safety.

The Mobeye CombiGuard integrates multiple sensors to detect temperature changes, water leaks, battery voltage levels, power supply interruptions, and potential-free signals. It sends instant alerts through the app (iOS/Android), phone call, text message, or email when a deviation is detected. Users can configure multiple contacts and customise how each receives alarm notifications.

This multipurpose monitoring system can operate for over a year on a single set of batteries. When the voltage drops below a defined level, it automatically sends a low-battery alert. If connected to an external power supply (12–24V DC or mains), it also monitors for power failures — often providing the first sign of an issue requiring immediate action.

 

Combined Water and Temperature Alarm — Plus Much More

Alongside water leak and temperature monitoring, the Mobeye CM4600 tracks battery voltage, shore power supply, and external sensor inputs — all in one compact device.

Key Features

The Mobeye CombiGuard CM4600 remote boat monitoring alarm includes:

  • Temperature sensor
  • Water leak sensor
  • Two inputs for battery voltage or potential-free contacts
  • Monitoring of (shore) power supply or 12–24V DC
  • Open collector output

The digital temperature sensor provides exceptional accuracy and allows the minimum and maximum temperature limits to be adjusted within a range of -35 °C to +70 °C. It is factory calibrated and displays readings in decimal format.

The leak sensor detects the presence of water-based liquids and immediately triggers an alarm when its two pins come into contact with water. For applications requiring water level monitoring instead of leak detection, the water float sensor (AC-WS-FS1) can be connected to one of the inputs.

The two inputs can be configured for analogue voltage measurements ranging from 0 to 48 volts, with peak tolerances up to 60 volts. This capability makes the CM4600 ideal for monitoring battery voltage. The battery can be automatically disconnected via the open collector output.

If one or both of the inputs are not used for analogue battery voltage measurement, they can function as potential-free (NO/NC) inputs. These inputs can be connected to alarm contacts such as a magnetic contact, water float sensor, or fault signal.

An intuitive online portal and mobile app simplify configuration and provide real-time insight into sensor statuses and connections.

Mobeye 4G Boat Alarm & Monitoring System

The Mobeye CM4600 functions as a full boat alarm and monitoring system, alerting you when:

  • Battery voltage drops below the set threshold (two batteries can be monitored independently).
  • (Bilge) water is detected (bilge alarm).
  • The temperature exceeds upper or lower limits.
  • There is a failure in the (shore) power connection.

An additional input can be configured for a sensor or fault signal — for example, to monitor water pump activity.

How the Mobeye CM4600 Works

Mobeye CM4600 Boat Alarm how it worksThe Mobeye CombiGuard CM4600 provides remote, real-time monitoring. When a sensor detects an abnormality, the system immediately sends notifications to your chosen contacts, giving you total control wherever you are.

  1. Attach one or more of the included sensors, adapter and/or connect a battery to monitor voltage. Set specific battery and temperature limits.
  2. The CombiGuard is designed to detect any deviations in the sensors and inputs. When connected to external power, it also records power failures.
  3. In the event of a deviation, the CombiGuard sends alert messages to designated contacts via the app (available for iOS and Android), phone calls, SMS, and/or email.

Typical Applications for the Mobeye CombiGuard CM4600

The Mobeye CM4600 CombiGuard is ideal for monitoring:

Example Use

For boat owners, the Mobeye ShipGuard provides constant oversight and peace of mind. It delivers real-time information about your vessel’s condition, even when you are away, allowing you to respond immediately to any issues or emergencies.

Beyond marine use, this unit suits any environment where temperature, water detection, and power monitoring matter. It tracks key conditions continuously. Instant alerts fire if temperatures exceed thresholds, water is detected, or power fails. Ideal for unattended properties, technical installations, storage areas, and remote locations — it delivers early warnings before damage occurs.

In addition to monitoring, the built-in control outputs enable remote operation of external equipment. Using your mobile phone, you can switch appliances such as heating, air conditioning, or refrigeration on or off. This allows you to prepare a property in advance, for example, activating heating or cooling while travelling, so you arrive to a comfortable and secure environment. By combining environmental monitoring with remote device control, this system delivers reliable protection, operational efficiency, and complete control from anywhere.


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.


Need a bilge water level alarm? The Mobeye WaterGuard-FS CM4300FS will alert you when bilge water reaches a specified level.
