So your build date shows November 2018, so this is probably the PTZ that came out prior to the version with autotracking. Yes they are sometimes lazy and use the same model name.
It was mid-late 2019 that the autotracking version came out and then sometime late 2020 is when Dahua removed autotracking. But some of the prior models could accept the firmware.
So it is a complete crapshoot on purchasing an older 49225 if it is capable or not.
But with that said, your cut/paste above shows it was last upgraded two days ago, so how do you know the firmware didn't magically take?
There is not an autotrack button or tab in the GUI. It is subtle.
It is part of the setup.
Make sure you are using Internet Explorer - not Edge or Chrome with the IE tab. The Dahua PTZs need Internet Explorer or your track time will default to 15 seconds regardless what you put in.
You need to set up a preset.
Then you need to set-up the Smart Plan with Deep IVS for the presets you want to track.
Then select the object filters you want.
Then go to Deep IVS Rules Config page and you should see Track Time under alarm and Tracking Target size slider.
When setting up IVS rules, I strongly recommend you use intrusion box with appears and crosses instead of tripwire. And less is more. One IVS rule.
Leave min size as 0,0
Make sure that Motion Detection and Smart Motion Detection are turned off.
I repeat, make sure Motion Detection and Smart Motion Detection are turned off LOL.
If you do not have the above screen with the Tracking Target Size, then you have a version without autotrack.
