Q: What should I do when the image has banding and flicker? 
A: This can be adjusted from the option in “Options” -> “Video Capture”. The switching of 
50Hz/60Hz can be found here. The issue should be solved from the option here. If the outdoor nature 
light is strong and the lighting indoor has caused the banding, turn off the indoor lighting or lower the 
outdoor lighting (close the curtain) can solve the banding issue.
