In the last weeks I spent a lot of time to upgrade my system for recording infrared videos. I replaced the old 0.4MP camera with a 3MP camera with a wide-angle lens. The illumination is now via 9 infrared LEDs (previously one LED) and is now recorded at a frame rate of 60fps (previously 25fps).
The modification was worth it: resolution, depth of field, recording area and frame rate have multiplied. The following recordings have already been taken during the first test runs.
You will find more videos here.
