Glomex ZigBoat™ Door/Porthole Sensor

The Glomex ZigBoat™ Door/Porthole Sensor is a vital addition for any vessel owner serious about marine security and real-time cabin monitoring. After years on the water, you learn quickly that unattended hatches, portholes, and cabin doors are vulnerabilities—whether you're anchored overnight, docked at a busy marina, or stepping away for a few hours. This wireless sensor integrates seamlessly into modern marine monitoring systems, alerting you instantly if any monitored entry point opens unexpectedly, providing peace of mind whether you're above deck or away from your boat entirely.

Built by Glomex Marine Antennas, a trusted name in marine electronics, the ZigBoat™ Door/Porthole Sensor uses reliable wireless technology to detect door and porthole movement without requiring hardwired installation. The compact design—measuring just 5 x 2 x 7 inches and weighing only 0.2 lbs—fits discreetly on frame edges or trim without drawing attention or interfering with normal operation. The sensor's low profile and lightweight construction make it ideal for retrofit installations on vessels of all sizes, from center consoles to cruising sailboats, without requiring structural modifications or complex electrical work.

Cruisers, live-aboards, and commercial operators benefit most from this practical security solution, especially those who leave their vessels unattended for extended periods or operate in high-traffic anchorages. Installation is straightforward for anyone comfortable with basic boat systems—mount the sensor on the door or porthole frame, pair it with your ZigBoat system hub, and begin receiving alerts to your smartphone or onboard display. The sensor works with all standard ZigBoat™ compatible hubs and monitoring systems, making it an economical way to expand your boat's security network one cabin access point at a time.
