In playback mode, QNAP multi-channels playback support up to four channels playback at the same time. However, we found the playback view time of four channels are not synchronized. Why?

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).
