FLIR M232 Pan/Tilt Marine Thermal Camera Review

FLIR M232 Pan/Tilt Marine Thermal Camera Overview

The FLIR M232 Marine Thermal Night Vision Camera is FLIR’s most affordable and smallest sea thermal night vision camera that has pan and tilt capabilities. Its features include a clear thermal resolution of 320×240 and a 4x digital zoom, facilitated by the latest generation Boson™ thermal core, which enables boaters to see clearly at night.

Integration with Raymarine Axiom

When paired with a Raymarine Axiom display, the M232 leverages FLIR’s ClearCruise™ intelligent thermal analytics technology to provide boaters with superior awareness and safety. ClearCruise™ delivers visual and audible alerts when “non-water” objects such as boats, obstacles, or navigation markers are detected.

Simple Installation and High-definition Imaging

Multiple manufacturers support easy plug-and-play installation. A detailed, crisp image quality of up to 720p high definition can be enjoyed right on your MFD via standard video over IP. A optional IP to Analog video converter exists for connecting the M232 to regular video monitors or MFDs without video over IP support.

Enhanced Navigation and Safety

The M232 promotes safety by aiding in the visibility of objects such as bridges, docks, buoys, and other vessels both night and day. It also aids in the quick discovery of people in the water in case of emergencies, surpassing the efficiency of spotlights and radar alone.

Long-range Optimized Viewing

The M232 ensures optimal horizon-to-horizon viewing with a clear 320 x 240 resolution. It includes a 4x digital zoom for efficient long-range performances.
