Thermal imaging camera
The thermal imaging camera - in this case it is the FLIR Lepton thermal imaging sensor, mounted above the camera - is intended for professionals - builders, rescuers - and here I have no right to comment on the effectiveness and accuracy of this element's work. For me, it was primarily a curiosity that allows you to look at the world from a completely different angle.
Thermovision in a smartphone is a great gadget for both more practical and purely entertainment applications. In fact, I used this camera more than my normal photo camera. I was able to look for thermal bridges and check the tightness of the heating installed on the block. I was able to check which cars in the parking lot came as the last ones (i.e. they have not had time to cool down yet) or how much the phone or laptop is warming up.
There are many applications for a thermal imaging camera, not only in the entertainment aspect - it is a specialized, precise tool that will show its full potential in the hands of a professional. Especially that thermal imaging sensors detect the heat emitted by objects and people without relying on visible light - thermal sensors can see in complete darkness and despite obstacles such as fog and smoke. Practical applications include locating electrical short circuits, hot spots, leaks, sources of moisture, etc. In pandemic times, the best use is to measure body temperature remotely, without even having to approach the person. However, let's add that the manufacturer points out that the thermal imaging camera is not a medical diagnostic tool and should not be a substitute for a real thermometer.
From the technical side, we have here the FLIR Lepton 3.5 sensor - it is the radiometric core of the FLIR thermal imaging camera with the highest resolution (160 x 120) in the Lepton family of sensors. As a result, it provides greater detail and quality of the thermal image. The sensor is to operate in the temperature range from -20 to 400 degrees Celsius. It is also supposed to detect heat sources at a distance of up to 30 meters. It also gives the measured temperatures with a tolerance of 5 degrees Celsius. Compared to the sensor in the previous model, CAT provides better image quality (4 times more pixels).
An essential complement to the sensor is MyFLIR Pro. Apparently, this software has been developed exclusively for the CAT S62 Pro model for 12 months - it means that you will not find this technology anywhere else. The application not only allows you to take photos and recordings - there is also a whole lot of additional functions. It allows you to prepare stop-motion animations, you can also stream video to YouTube live. Thermal images can be combined with images from a 12-megapixel camera - this is MSX (Multi-Spectral Dynamic Imaging) technology. It allows you to adjust the intensity of image detail and edges superimposed from the camera image onto the thermal image, providing overall situational awareness and context. In addition, the application provides VividIR - it is a FLIR image processing technique that improves its quality.
MyFLIR PRO can display several types of image: only from a thermal camera, combined with linear detail superimposed on the image (MSX), with an overlay of thermal and visible images (Alpha Blending), and only from the main camera. In MSX and Alpha Blending modes, you can additionally use sliders that allow you to align the thermal and visible image and change their intensity.
The user can also choose from different colour filters for the thermal imager - the default is Iron, but there are a total of nine options that are displayed as live thumbnails. What's more, you can place points and wider areas for temperature measurements (in the form of moving and scalable rectangles, circles or lines) on the images.
Using the thermal imaging camera is simple and intuitive - just launch the application and point the sensor at the area or object you are interested in. You can see that the application can load the components quite a bit, and the image appears with some delay, but it does not interfere with the use of the phone and thermal imaging in any way. The work of the FLIR module results in images with a resolution of 1440 x 1080 pixels and Full HD video. There is even an application that presents photos and recordings made with a thermal camera (Gallery). Here you can generate reports on the infrared image (date and place of measurement, temperature range, etc.).
CAT S62 Pro is a rugged device - which means that it is to withstand contact with dust and water and is to be resistant to falls and extreme temperatures. Without it, it is difficult to imagine the use of this smartphone in more difficult conditions. The smartphone has military certification MIL-STD-810H and IP68, and has Gorilla Glass 6 on the screen. In theory, CAT S62 Pro is to withstand a fall from a height of up to 1.8 meters and can survive submerged to 1.5 meters for 35 minutes . It is also resistant to vibrations.
The device can be used in the operating temperature range from -25°C to +50°C. According to the documentation for this model, CAT S62 Pro will also withstand extreme temperature changes: very quick transfer from a cold place to a hot place and vice versa. The manufacturer only adds that it should not be used in temperatures outside the range of 0°C to +45°C without protective gloves.
And in practice? The smartphone was left for 30 minutes in the aquarium, I washed it under running water, it survived several falls (one left a slight mark on the metal corner), it was also used to sweep away snow. It wasn't spared in any way... and still works fine.
