I don't have the NVR, but do have a 5442-S3 ... and a T54PRO-ZE.
Both of those seem to working fine WITHOUT the plugin using both Edge and Chrome - this is on Windoze 11 and a recent build ... so never installed the plug-in.
I.e. I can view the live image, adjust zoom/focus/etc., see and modify the the various menu's, etc.
The ONLY issue that I've seen is when downloading recording videos. It doesn't always work if I try to do more than one at a time ... and the download speed is painfully slow ... appears to be "capped" at 10MBit/sec ... which implies some sort of software limitation.
I assure you the camera is connected at 100Mbit/sec ... and for instance, when I take a Snapshot via the Web Browser, it
downloads that ~10 MByte PNG in about a second ... rather than 10. So it's not the wire speed.
While I can wait several minutes for 200-300 MByte .dav to download, it's a bit annoying. Any chance
@EMPIRETECANDY you can file a bug report and see if Dahua can fix this?
