Hello,
I own several  
SD4A425DB-HNY 4MP 25x (Mini PTZs) from EmpireTech. I find it to be a discreet, and quite capable camera, if only it  were a bit brighter at night, otherwise, it is perhaps my fav PTZ.  Ever since I updated  the original factory FirmWare to the,  
2023-07-04 build (V2.821.000013.1.R),  I lost the ability to choose from the GUI,  the 
OSD info to display on the camera's live feed. (temperature, zoom, coordinates, etc). The path to this tab is  
Setting / Camera / Encode / Overlay / OSD Info.
This feature was fully enabled in the original factory FW, but  after this update,  when I now click on that tab  
(OSD info), the computer GUI screen goes blank white, and does not recover, forcing you to log back in.  All my 
SD4A425DB-HNY (8), do the exact same thing. This happens regardless of browser (Explorer, Chrome, Safari).
I recently saw there was a new FW posted for this cam on 2024-01-22.   
System 3.200.0000006.0.R Build Date 2023-12-21 , so I updated a couple cams just to see if this feature would now work, but unfortunately , nothing changed, and it does the same erratic blank screen once you click the 
OSD info tab. So I decided to not update the rest, because I am not a big fan of updating , unless there is  a serious issue.
Andy  helped me a great deal, to set them up initially , when they were  just purchased, but with this specific issue, I decided instead  to post and ask here in the forum, if perhaps anyone that owns, and has experience  or is familiar with this particular cam, has run into the issue I describe? Or can perhaps replicate the path to see if it works on their current build.
Any help , would be greatly appreciated.
Thanks,
Luis
