Oh that is a model Hikvision intentionally removed autotracking with an update to force people to buy the more expensive PTZ (*V5.7.3 220315 -Remove auto-tracking functions on DE4A) and if I recall correctly, they don't allow older firmware to be installed.
One of the many reasons why we preach here not to update a firmware for OCD kicks and grins behavior. Back when that camera came out, we got lots of posts here of people losing autotracking by updating their camera.
Unless the firmware release notes specifically states it is fixing a problem you have, in many instances it removes a feature you were using.
Don't fix what ain't broke LOL
And time is money, so assign a dollar value to your time (like how much you make per hour) and how much time it takes to search for the cheap camera, buy cheap camera, play with it and decide it is junk, pack it up and take camera to wherever you take it to return it, start process over with another camera, and you could have "paid" for a good camera LOL.
