Unexpected Entry

A door, locker or hatch is opened when it shouldn’t be.

Engine Running

Engine activity detected when it shouldn’t be.

A NMEA 2000 drop cable is included to connect the Boat Monitor directly to your vessel’s NMEA 2000 network.

SWITCHING & INTEGRATIONS

PLUG INTO WHAT’S ALREADY THERE.

SafeGuard PLUS can do more than monitor your boat. Through BM-50 Standard, Sentinel can become part of a broader onboard ecosystem, enabling remote switching and integration with compatible digital switching platforms.

NATIVE RELAYS

Simple digital switching — out of the box

BM-50 Standard includes 1 built-in Remote Control Output, allowing simple remote switching directly from the Sentinel app. You can control selected onboard equipment such as:

  • Lighting
  • Refrigerators
  • Pumps
  • Other supported onboard systems

Additional Remote Control Outputs can be added through Sentinel Hub.

Disclaimer
Some onboard equipment may require additional interface hardware depending on the system configuration and power requirements.

CZONE · EMPIRBUS · SIMARINE · OTHERS

Integrate with existing systems

Sentinel can integrate with compatible digital switching and onboard monitoring systems such as CZone, EmpirBus, and Simarine — allowing deeper onboard visibility and expanded control possibilities through existing onboard infrastructure.

This means SafeGuard Plus can become part of a larger connected boating ecosystem rather than operating as a standalone monitoring device.

Disclaimer
Some integrations may require additional third-party subscriptions, hardware, certifications, or compatibility verification.

How to install

Installation
Your choice.

Sentinel can be installed professionally through our certified partner network — or set up on your own using step-by-step video guides.
