View Area
A view area is a cropped part of the full view. Each view area is treated as a video source in
Live View
and has its own video
stream and PTZ settings.
When setting up a view area, it is recommended that the video stream resolution is the same size as or smaller than the view area
size. Setting the video stream resolution larger than the view area size implies digitally scaled up video after sensor capture,
requiring more bandwidth without adding image information.

Overlays
Overlays are superimposed over the video stream. They are used to provide extra information during recordings, such as a timestamp,
or during product installation and configuration. You can add either text or an image.
About overlay text
An overlay text can include the current date and time, or a text string. When using a text string, so-called modifiers can be used to
display, for example, the current bit rate or the current frame rate.
