<5~32000>,
<1~8000>,

etc.
* Available value is listed
in
"capability_image_c<0~(n-
1)>_exposure_maxrange"
4/4 Exposure time
1~32000 => 1s ~ 1/32000s
5~32000 => 1/5s ~ 1/32000s
1~8000 => 1s ~ 1/8000s
5~8000 => 1/5s ~ 1/8000s
etc.
* This parameter may also restrict
image frame rate from sensor due to
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
"capability_image_c<0~(n-1)>_exposu
re_maxrange" != "-" and
"capability_image_c<0~(n-1)>_exposu
re_rangetype" is "onevalue".
* We support this parameter when
the version number (httpversion) is
equal or greater than 0302a.
