Get or set the Day&Night detection timer.
To have stable Day&Night detection, the Day&Night detection timers is good approach. The camera will monitor its internal gain level or the CDS output level to determine its Day&Night state. Add the detection timer, the camera changes its Day&Night state if its gain level or CDS output level has been stayed at a certain level for the detection timer interval. Please refer to the Day&Night Control Camera Page Design Specification for further details.
There are two timers in this URL. The first one is DayTimer and the last one is NightTimer. Both of them are in seconds and the range is from 0 to 255.
When CDS is used for Day&Night detection source, the DayTimer and NightTimer have to be set to the Day&Night control module. This module will monitor the output of CDS with these timers to determine the Day&Night state.
When the DSP gain level is used for Day&Night detection source, the firmware monitor the DSP gain with these timers to determine the Day&Night state.
The error message, VIDEO_DN_TIMER not found, will be returned if the encoders and camera do not support Day&Night function or there is no Day&Night detection function.
