Dahua Setup

These are the recommended settings to get better quality live view and event/time-lapse snapshots.

On the Camera

Dahua substream settings

Set as follows:

  • Enable: tick Enable
  • Sub Stream: Select Sub Stream 2 from the dropdown
  • Resolution: select the highest the camera can provide
  • Framerate: 4 to 6 fps
  • Bit Rate Type: CBR
  • Bit Rate: 2048 (or highest available)
  • I Frame Interval: double the Framerate (e.g. 8 or 12)

Important: Make sure you are selecting "Sub Stream 2" in the dropdown as shown in the screenshot above.

Tip: Code-Stream Type is missing on some models - this option is not important.
