The DIY-Thermocam V3 gives private persons, educational institutes and companies access to a portable, affordable and customizable thermal imaging platform that is based on open-source software and hardware. It is constructed as a self-assembly solution, that can be build at home by only using some standard tools.

There are various applications like finding heat leaks in the insulation of buildings, the analysis of electrical or mechanical components, the detection of persons / animals or even mounting it on a drone and recording continuous or time-lapse images.

The device has a large ecosystem of software around it, that allows to extend the functionalities of the device beyond the firmware itself. You can use the Thermal Analysis Software to edit raw data files on your PCand save them in various file formats. In addition to that, the Thermal Live Viewer can stream live thermal images to your PC, change settings on the fly and record images or videos. The Thermal Data Viewer provides another way of editing raw files, and with the Video Converter you can convert series of captures images to movie files.
