Does BI detect that the image is fully B/W, when the camera has switched to IR mode or does it still do its color difference calculations in the full color range and effectively requiring me to input a much lower contrast limit to trigger motion during night time, if I have the "black and white" option unticked?
Should I perhaps have it ticked all the time?
Cameras switch to IR mode based on available light instead of specific time of day.
