Got the last of the new cameras installed, this one's been up about a week now (IPC-HFW5231E-Z5E ) and I have 2 issues that may be related. First is this spec that is visible at night, pics are zoomed all the way in then zoomed all the way out for reference. Second is that when the camera is zoomed all the way in, when it switches to night mode, auto focus de-focuses the image. I'm not sure if this spec has anything to do with it or not but to get it focused, I have to manually move the focus slider full left with the zoom slide full right. I hope that makes sense.
