Motion detection NV4108

[blafrisch]

I have 4 cameras of various brands currently set up in my NV4108, all of them are configured as ONVIF cameras. Only one of them is allowing me to configure multiple detection zones, the others don't have any zone configuration besides the "red zone", the dropdown never appears. Additionally only the one camera has the ability to set the threshold+sensitivity for motion detection, again because the dropdown never appears for the others. Also, can multiple detection zones only be defined on the local device? I cannot seem to find any such option when using internet Explorer.
