Garmin OnDeck Security Sensor

The Garmin OnDeck Security Sensor is a magnetic entry detection device designed to protect vessels and watercraft from unauthorized access. This compact, wireless sensor integrates seamlessly with the Garmin OnDeck Hub ecosystem, providing real-time alerts when doors or windows are opened unexpectedly. Built for marine environments where security and peace of mind are essential, this sensor is ideal for boat owners who want reliable perimeter monitoring without complex wiring or installation hassles.

The sensor operates on a magnetic reed switch principle, triggering an alert the moment the magnetic field is disrupted when a door or window opens. This proven technology requires no batteries on the magnet itself and communicates wirelessly to your OnDeck Hub, keeping your network secure and clutter-free. The lightweight design at just 1 pound makes installation unobtrusive on cabin doors, porthole windows, or hatch covers, while the weatherproof construction ensures reliable operation in harsh marine conditions with salt spray, humidity, and temperature fluctuations. The sensor pairs directly with Garmin's OnDeck app, enabling you to receive notifications on your smartphone or tablet wherever you are.

Boat owners, liveaboards, and fleet operators benefit most from this sensor, particularly those docked in busy marinas or extended anchorages where theft or trespassing is a concern. Installation is straightforward—mount the sensor on the door or window frame and attach the magnet to the moving panel; no drilling or electrical work required. The Garmin OnDeck Security Sensor works exclusively with the Garmin OnDeck Hub and compatible Garmin marine systems, making it an essential addition to comprehensive vessel security systems. For multi-point protection, users can deploy multiple sensors across different entry points and manage them all from a single OnDeck Hub interface.
