* Available value is
listed in
"capability_image_c
<n>_exposure_ma
xrange"
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<n>_exposure_maxrang
e" != "-"
* Only valid when "piris_mode"=manual or
"irismode"=fixed
enableblc
<Not support anymore>
<boolean> 4/4 Enable backlight compensation.
* Not support this parameter anymore when
the version number (httpversion) is equal or
greater than 0301a.
* It's recommanded to use
"exposurewin_c<n>_mode" to switch on/off
BLC.
