Answer:

The reasons why the four channels playback view do not synchronize because of different file sizes were being transferred thru the network’:

  1. The frame of video is generated every second. A higher FPS means smoother video and larger file size.
  2. The resolution setting of the camera. A higher resolution (e.g. 1.3M pixel) get larger generated file, if compare to VGA resolution (640x480).
