I believe I may have found the issue with the out of focus overnight. After going back through my LPR screen captures, I noticed that the LPR east camera went out of focus right after midnight. I checked the schedule at both ends and from 00:00:00 to 00:00:57 the schedule was blank (just white) on every month. I have a feeling it switched to a new mode and was trying to focus on the dark, so it stayed out of focus. I have adjusted that section to be part of night mode, so it is continuous from 18:00:00 to 07:00:00. Hopefully, that corrects the out of focus issue.
