I asked a guy that work for Hikvision, the same question, and the answer was "There is no other way". There is no way to identify it. (besides the ones allready mentioned.)
Can someone explain me the use/setup, maybe an example of the "zoom ratio", since i have no clue what this is for
It's on an DS-2DE4A225IW-DE , but if im not wrong, the button is on every ptz from hikvision ;-)
Configuration/PTZ/Intelligent tracking/
Thank you :)
