DESCRIPTION
"capability_image_c<0~(n-
1)>_exposure_maxrange"
sensor generates a frame per
exposure time. Ex: If this is set to 1/5s
~ 1/8000s and camera takes 1/5s on
the night, then sensor only outputs 5
frame/s.
* Only available when

* Only valid when
"piris_mode"=manual or
"irismode"=fixed
* Only available when
