All, I was asked by Dahua to provide a further walkthrough on SmartIR testing on the 21-05-06 FW to help them pinpoint the issue. Therefore I re-ran the tests, included the menu settings, OBS screen recordings, my recommendations on how to fix with a demonstration on how it improves the image and an updated comparison to 11/23.
While 11/23 wasn’t perfect, we did get it tweaked by Dahua to pretty good after the testing / feedback here and with the small additional tweaks I showed at the time worked very well. For clarity, in the How To Fix section, I’m not saying that Dahua should be dropping Exp. Comp all the way down to what I show in the video but I use it as a guide for them on where they could start focusing to fix Exp. Comp as well as IR strength and response of these to changing target / lighting in scene. This would be a great place to start as I showed in the last video where the differences between FW in these values is apparent. Including the new video link here so you have access too.
