FLIR M-324CS Stabilized Thermal/Visible Camera Review

Thermal imaging technology is an emerging trend all around as we can use it for inspecting the faults in every field right from an electrical, mechanical, building, military, coastal guards, etc.

Now here we’re to discuss the various benefits of FLIR–M324CS Thermal Camera System, You may doubt on what are the key points to look up in this camera? From my research, I’d say that the 640 x 480 thermal sensor and optical zooming are the major factors for the FLIR M324CS camera to stand out from other cameras.

Product Specs

The M324CS comes with a higher resolution rate plus the lux value of 1.4 daylight camera for identifying the distant targets.

The enhanced Gyro stabilization gives 100% clarity pictures at your rough and tough travel journey.

An additional benefit is the 360-degree(pan and 90 degree tilt) as it offers a safeguard measure at all times.


This camera features a high-resolution camera which comes along with 36x optical zoom for providing a vision at daylight and lowlight conditions


The M-series easily integrates with already existing electronics from Simrad, Garmin, Raymarine etc. It has a joystick control unit which fully controls the camera


The FLIR M-324CS features a Gyro stabilization which offers steady images even at tough conditions.

Optical zoom

As I’ve said before, the visible light camera is attached with a 36x optical zoom which is an excellent factor that adds additional value for this camera.

I’ve used this camera for my hunt a few months ago and from my experience, I’ll advise the future hunters to get this camera for their wildlife or marine adventure.

You can visualize the target during the day as well as night for taking stunning visuals of the specific object.


In this video you can see the difference between thermal image and low light image( 320 x 240  resolution and 640 x 480 resolution)

JCU(Joystick Control Unit)

So what’s JCU? All the M-Series cameras are included with JCU which provides an accurate system control and offers convenience for the users to access the camera functions with just a push of a button.

If needed the user can mount additional JCUs to control the camera from various locations. The Joystick is backlit for use during dark times and is completely wrapped to IPX6 standards so this can be mounted in the pilothouse or other surface.


Not only JCU can control the M324CS camera it can also be viewed and controlled by many leading MFDs from Furuno, Garmin, Raymarine, and finally Simrad.

Video Display

What’s specific to look at this camera? The M-series thermal imager uses an infrared energy band to produce the images so you can see the difference in temperature.

It does not use visible light like other cameras which is the major reason for producing clarity images.

Thermal Imaging Modes

There are two different modes in this camera- Black hot mode and white-hot mode.

If you switch the camera to white-hot mode, you can visualize the difference that the warm objects will be highlighted in white color or gray(light), whereas the cold objects will be shown in black color or gray(dark). The video can be reversed by changing the settings of polarity.


No matter whether the mode is white-hot or black hot, the camera will automatically optimize the images to produce the best scene in every condition.

JCU/Camera Installation

You can install the camera either at upright or upside down, make sure that both sides are accessible.

The mounting surface should be larger than the footprint of the camera just to ensure an adequate seal with O-ring.

The top-down mounting accessory kit will be useful for fixing the camera at the position that uses the mounting riser which will allow enough space between the camera base and mounting surface for enlarging the connections.

Comparison of FLIR M625 and M324


In this video you can see the different IR modes and zoom levels, the camera is kept at 15nm distance and 4x zoom for both the models but you can see the clear view of the ship by FLIR M625.

Next, we keep on increasing the distance to 25nm, 75nm you can see the difference in this video.

Finally, the value is set to 1.0nm with 4x zoom(M625) and 1.0nm for M324, the ship is viewable a little bit through the first camera, in the second screen nothing is shown, only the waves are viewable clearly.

Final Words

Marine thermal cameras keep you under the safe state and allow you to feel free through rivers and open water areas.

FLIR M324CS is one of those cameras so I opt you to choose this product and wish to enhance your boating experience.
