Maretron Motion Detector f/SIM100

The Maretron Motion Detector for SIM100 is a passive infrared (PIR) motion sensor designed to integrate seamlessly with Maretron's SIM100 gateway for comprehensive NMEA 2000 network monitoring on marine vessels. This accessory sensor expands the surveillance and security capabilities of your boat's networked systems, allowing real-time motion detection alerts to be distributed across all connected display units.

The PIR technology detects thermal variations from moving objects within its sensing range, triggering alerts that integrate directly into your NMEA 2000 network architecture. This means motion events can be monitored from any networked multifunction display, chartplotter, or compatible device aboard your vessel. The compact 3 x 3 x 4 inch form factor and lightweight 1 lb construction make installation flexible for cabin security, engine room surveillance, or storage area monitoring. The sensor attaches directly to the SIM100 module, eliminating the need for external wiring or complex retrofitting.

Recreational boaters and charter operators use this motion detector to monitor unattended cabins when the vessel is moored or docked. Serious cruisers who maintain sophisticated onboard networks leverage it as part of broader security systems that log events to their integrated marine electronics. The sensor is particularly valuable for overnight anchorages, slip monitoring, or detecting unauthorized movement in secured compartments. Because alerts feed directly into your NMEA 2000 ecosystem, you maintain situational awareness from any networked display without requiring separate monitoring hardware or additional subscriptions.

Maretron's SIM100 ecosystem supports modular security and monitoring sensors that work within established marine network standards. The motion detector is one component of a broader integrated approach to vessel monitoring—compatible with other SIM100 sensors and displayable on any NMEA 2000-capable unit in your system.
