Why is there a part of channels displaying “No Resource” or turning black screen in multi-screen live view?

Reason

  1. Sub-stream resolution or bitrate settings is inappropriate.

  2. Connecting sub-stream failed.

Solution

  1. Go to Camera > Video Parameters > Sub-Stream. Select the channel, and turn down the resolution and max. bitrate (resolution shall be less than 720p, max. bitrate shall be less than 2048 Kbps).

    Note:

    If your video recorder notifies not support this function, you can log in to the camera, and adjust video parameters via web browser.

  2. Properly set the sub-stream resolution and max. bitrate (resolution shall be less than 720p, max. bitrate shall be less than 2048 Kbps), then delete the channel and add it back again.
