Only annoyance with this firmware - the cameras just register as "IP Camera" on my DVR instead of a specific model (like the previous firmware version I had did). When you hve as many different models in your system as I do, it's nice when the cameras identify themselves correctly!
 
@Sunfox, what NVR are you using? I see the model numbers in my NVR14108-P-4KS2 After applying this firmware on my cameras.

It’s a NVR5216-16P-4KS2E (2018). Previous firmware I had on these cams showed the correct model, and it does so for 4 other different Dahua models I’m using. (All with firmware updated yesterday). I’ve seen this before on this and at least one or two other models, and I thought it was more specific to “unbranded” firmware versus Dahua original. But I definitely like the improvements in this firmware.
