KTM modules are modern thermal imaging cameras intended for observation in visibility conditions, both day and night. They are built on uncooled bolometric detectors with VGA resolution and pixel size of 12 μm. Thanks to the lesser pixel size of the sensor, the KTM has the much smaller dimensions as our previous KTL modules. KTM modules can be equipped with athermalized lenses with different angles of the field of view and an additional shutter for calibration. The video signal is transmitted in the digital MIPI CSI‑2 standard. KTM cameras can be used, for example, in monitoring rooms and areas, during search and rescue operations, in the supervision of technological devices and installations, and as sensors in small observation gimbals for drones and other unmanned aerial vehicles. Optionally, the module can have a particular function indicating objects with a temperature within a defined range by colouring a proper part of the image.
