Because they want to sell the $800 PTZ...back to previous version no problems.
Why would they remove auto-tracking from F/W? Tracking works as well as most other PTZs....
But you learned a lesson and got lucky this time...next time maybe not...
So you really need to ask yourself, why am I updating? If it is just for kicks, then stay with what is working.
A common theme around here is don't fix what ain't broke. If the unit is working and meets your needs, in many instances an update breaks what you had working and provides you with something you didn't need. A Dahua Z12E that someone updated and then constantly reboots comes to mind; a certain Dahua PTZ that loses autotracking with an update come to mind, a camera that loses nightvision with a firmware update; a Hikvision ANPR camera losing half the FPS and loses the ability to read US plates - those are big deals to have happen. Don't do it unless it is fixing a problem you are experiencing or adds a feature you really need. In many instances, the camera cannot be rolled back. Count yourself lucky.
Further, it is best to obtain any firmware updates from the vendor you purchased it from so that you do not run into issues. Any firmware you find here or elsewhere is obviously proceed at your own risk. We have many threads here where someone tried an update with a firmware they found on the internet and bricked their unit.
Many units being sold are Chinese hacked units that will either brick or go into Chinese upon updating. Some vendors will be upfront and tell consumers that as part of their website, but many do not or the consumer forgets...here is one such example....
