PTZ Controller supports standard protocol. For most PTZ cameras, OSD menu can be opened on Menu panel of PTZ Controller.
Some PTZ cameras are not fully compatible with standard protocols. Just like OSD Menu function, it is not a standard rule for every camera.
Most PTZ cameras use Preset 95 to access OSD Menu. There also have some using Preset 57, and some may use other command.
You can find the exact command for it in the user manual or specification of your PTZ camera, and then add the command to the Customize panel of PTZ Controller.
