I cant find much but I have around 30 of them being installed, they are ptz poe ethernet cameras. Can you tell me how to set the default location on powerup to a specific ptz position? I am using a Dahua DH-NVR608-64-4K 64 Channel NVR The Cameras are PDN22T204GN(on box) which I think is a PTZ IP9622 (SD22204T-GN)
