PLUG INTO WHAT’S ALREADY THERE.
No checking, no wondering. Sentinel watches continuously and reaches out the instant something needs your attention — whether you're on the dock or a thousand miles away.
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.
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.
