Siren Marine Wired Micro ePIR Motion Sensor

The Siren Marine Wired Micro ePIR Motion Sensor delivers compact, hardened security monitoring for boats of all sizes. Designed specifically for marine environments, this wired microwave-based ePIR sensor provides early-warning detection at entry points and corridors where unauthorized access is most likely to occur. The extremely compact form factor—just 3 x 2 x 4 inches—allows installation on bulkheads, cabin walls, and tight spaces where larger ceiling sensors would be impractical or visually intrusive.

Unlike traditional passive infrared (PIR) sensors, the ePIR microwave technology in this motion detector cuts through salt air, humidity, and temperature fluctuations that typically degrade coastal and offshore sensor performance. The wired architecture eliminates battery concerns during extended mooring or off-season storage. Once triggered, the sensor transmits alerts directly to the boat owner's mobile device and can be programmed to trigger an audible alarm, strobe light, or silent notification depending on the boat's alarm system integration.

This sensor is ideal for fishing boats, cruising sailboats, cabin cruisers, and live-aboard vessels where cabin security between dockings or overnight anchorages is critical. Weekend anglers and serious offshore fishermen alike benefit from the low-profile installation and reliability in harsh marine conditions. The wired micro ePIR motion sensor integrates with most modern marine security systems, providing a layered defense that deters theft and tracks unauthorized entry before damage or loss occurs.

Boat security requires solutions engineered for saltwater exposure, vibration, and the unpredictable environment of open water. This wired motion sensor's compact, concealable design means it won't interfere with cabin aesthetics or draw unwanted attention in the marina.
