I've got a DH-SD6CE445XA-HNR running 2020-11-23 firmware (V2.810.0000017.0.R.P9.4512.UN.NR) that I bought from Andy and, while I don't normally use it, for my particular application have started using SMD, which is unreliable (to say the least) in my current firmware. There's a newer version of firmware for this cam on Dahua's website (Prometheus_MultiLang_NP_Stream3_V2.812.0000005.4.R.210902.bin) and I'm wondering if anyone has used it. I've read about new PTZ firmware removing autotracking and am just wanting to make sure this version doesn't do that. Any info appreciated.
