I would just like to be able to get rid of the zoom ability when touching the picture but still be able to use the PTZ buttons to zoom, since I find myself accidentally zooming when I'm trying to switch cameras by swiping sometimes.
Not sure if you are using an NVR or not, but maybe you could make 2 different users in your NVR software, one with the ability/permissions to do so and another without? That way you could prevent yourself (and others) from changing it! If you are using the native app, I don't know of a way either.
