Would you advise to use the timeplan in camera settings for example day and night?
While it is a royal pain to set up the time plan in the new GUI, the fact that we have more than just two profiles to use and can set up a profile for that pesky 2 hour window that needs WDR, I am becoming a fan of the new format.
If all you need are day and night and using BI or some other system that can automate based on sunrise/sunset, then using the APIs to call that probably makes more sense.
