Indicate the IR current mode, available value is “auto” and
“manual” mode.
optimizedir_c<0~(n-1)>_irnum:
The number of IR that camera supports.
optimizedir_c<0~(n-1)>_irstrength:
Only available when irmode is set as manual. It’s a set of
integers, which indicate the strength of each IR LED (e.g.
23,45,100,100).
optimizedir_c<0~(n-1)>_irstatus:
Current IR status, normal / adjusting:
"normal": the IR LED strength has been fixed.
"adjusting": the IR LED strength is adjusting.

Irmode needs to be set as manual for adjusting IR
LED strength.

strength values need to be the same as it of
irnum. However, it needs only one value for
strength when the operation is set as "settoall".
