All of the Amcrest "management" I do is within blue iris. I have a ptz IP4M-1041B but do not do any ptz stuff via HA. I use blue iris to send stream/alerts to HA via MQTT. This allows me to do notifications on motion. I would assume if you have location presets setup in BI you could call them from HA but that's a guess.
I messed around with presets (camera location) in blue iris a bit bit didn't have a real use case for it so I am not sure how robust it is.
I block internet access to all Amcrest cameras directly but can still access their local IP. I have access to my cameras again via blue iris which runs on a dedicated windows machine.
