The Oversea Entry Sensor is a self-powered wireless sensor detects when doors, hatches, cabinets or other access points are opened.

Designed to alert you immediately to unauthorized access into your boat, the Entry Sensor uses a magnetic reed switch to detect when an access point is opened. The Entry Sensor, smaller than other Oversea Sensors, mounts onto one side of the access point, and a small magnet holder mounts to the other side. When the two components are separated, an alert is generated.

In conjunction with the Oversea PIR Motion Sensor, the Entry Sensor provides a dual line of defense to alert you to any potential intrusions onto your boat.

When an entry breach is detected, you’ll receive alerts in the Oversea app, by e-mail and/or by SMS based on your specified parameters.

Because of the long range of the sensor’s RF connection, you can use a single Hub to monitor doors and other access points on more than one boat, provided the other boats are close by.

The Entry Sensor is compact — the main sensor is  (3.6″ x 1.1″ x 1.0″). It it lightweight (1.75 oz.) and built to withstand harsh marine conditions, with IP65/67 protection. It is powered by a replaceable CR123 lithium cell, which provides several years of operation per battery.

The sensor is shipped with various mounting options, including screws, Velcro tape and magnets.

Remember, Oversea devices require a subscription to activate, and currently only provides monitoring for boats located in the United States. You’ll find more information on subscription rates in the adjacent subscription tab
