Why are network camera images distorted?

Answer

Network cameras with CMOS and MOS sensors use a rolling shutter method, so image distortion may occur due to environmental vibrations or fast-moving objects.


In the rolling shutter method, the image is captured line by line instead of capturing the entire image at once, which may cause distortion of the image due to vibration caused by the environment or fast-moving objects.
