Oh, and when the ICR is active, the field of view is slightly more light on the right side. Not illuminated, but more lighter (grainy). This hints that IR mode is active. But still nothing.
This is strange. IR illumination is on, probably ICR mode as well, video works. What is the problem?
And: when using automatic ICR mode, it never turns off (to day mode) by itself, even in plain daylight, looking out the window. Otoh, I don't have oversaturation problem looking out, but it doesn't seem to work add I would expect.
