Description

Mobeye CombiGuard CM4600 Boat Alarm or “ShipGuard”

The Mobeye CombiGuard CM4600, also known as the Mobeye ShipGuard boat alarm or 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. Its communication module is capable of connecting to both 4G LTE-M and 2G networks.

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.

Key Features

The Mobeye CombiGuard CM4600 Boat Alarm includes:

  • A temperature sensor
  • A water leak sensor
  • Two inputs for battery voltage or potential-free contacts
  • Monitoring of (shore) power supply or 12–24V DC
  • An 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 CombiGuard 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 it 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 CombiGuard CM4600 is ideal for monitoring:

  • Boats and yachts
  • ICT server rooms
  • Technical installations
  • Storage facilities

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 monitoring and control unit is ideal for any environment where temperature stability, water detection, and power supply monitoring are critical. It continuously tracks key conditions and sends instant alerts if temperature thresholds are exceeded, water is detected, or a power supply failure occurs. This makes it perfect for unattended properties, technical installations, storage areas, and remote locations, providing early warnings that help prevent damage and disruption.

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.

SIM, Portal & App

All Mobeye monitoring devices require a SIM card for communication. The product comes with a budget-friendly SIM card, which provides direct access to the Mobeye Internet portal. Using your own SIM card limits certain functionalities.

SIM
The Mobeye M2M SIM card (low-cost, flat-fee, multi-provider) enables full functionality, allowing access to both the Mobeye Internet Portal and the Mobeye App.

With the Mobeye SIM card, communication occurs over the 4G LTE-M network with 2G as a fallback. When you insert your own SIM card, the device utilises the 2G network. Alarm messages are then transmitted via SMS and/or call to a maximum of 5 telephone numbers.

The Mobeye SIM card is PIN-protected and works exclusively in a Mobeye device. Do not insert it into any other device. For more information about the Mobeye SIM card, visit: mobeye.com/en/sim-cards. Details on the rates for using the Mobeye Internet Portal and SIM card can be found at mobeye.com/en/sim-portal.
