Now who is assuming. I may not decode the Dahua part numbers, or read a 57 page
wiki before I ask for a little help, but I looked in the Dahua referenced manual, and it showed PTZ operation. I dont care for these all in one Dahua manuals, confusing.
As for knowing bugs when I see them, I am an electrical engineer and have written software and manuals. I have designed and integrated large complex systems. I guess I know a bug when I see it, and there are plenty to be found.
I bought an Dahua Ultra DVR a year ago, and the firmware has not been updated since mid-2016. It is missing features I would expect in a high-end product, and it has bugs that have not been fixed. I could go into what they are, and you could enlighten me, respectfully.
