Most of Wisenet cameras have an option for positioning OSD (On Screen Display) like below image.
However, Wisenet 7 cameras does not have the same option for OSD menu. Please see the below.
Instead, if the OSD is enabled, you can see a small triangle of the OSD preview. And you can drag and move it to where you want. Then, after pressing 'Apply' button, the position of OSD will be changed.
