I've been lurking/learning for the past year. I've had a HFW5241E-Z12E for license plate capture (no LPR software) and two turrets monitoring my front and back yard. After countless settings-configurations on the Z12E only producing "meh" nighttime images I saw this post and decided to grab a HFW5242H-Z6E-MF (the last one Andy had in stock, sorry folks). I installed it today and I'm blown away by the difference a 1/1.8” sensor makes. Color mode under a street light looks like broad daylight. I'm looking forward to dialing in the settings.
However, the Z12E web interface is suddenly acting screwy ever since I temporarily disconnected it today when I repositioned it. I'd upgraded the firmware to V2.800.0000000.20.R, Build Date: 2020-09-03 three weeks ago with no issues, and I re-installed this same firmware an hour ago with no change to the problem after reinstallation and reboot. So here's the problem. Settings/Zoom And Focus on the Z12E web interface won't display a live video image. This is on the Edge browser I've been using consistently for the past year.

For comparison, this is Settings/Conditions for the same Z12E. The live preview is displayed as expected. Mode is set to Auto just so we're not looking at a pitch black image. And yes the same Auto setting is applied and saved when switching to Zoom and Focus. This is the same image that should be displaying on the Zoom and Focus tab.

For further comparison, here are the Zoom and Focus web interfaces for my other three cameras , each showing the live view as expected.
Edge - RDP BI server. T2831.

Chrome - RDP BI Server. T2231

Chrome - Laptop. HFW5242H-Z6E-MF

To confirm the problem, back to the Z12E: Chrome - Laptop

Firmware on Z12E:

Any ideas about how to fix this?
