Using TetherX with Dahua cameras

To achieve better quality live view and event/time-lapse snapshots with TetherX, we recommend the following settings for Dahua cameras.

Note: You may find the tunnelling feature useful in order to access the camera settings remotely.

In the Camera Settings

  1. For the primary stream, we recommend setting to H.264. You can learn more about H.264 and H.265 support here. For example:

  2. Enable Sub Stream 2 and select it from the dropdown menu.
    ​Note: If Sub Stream 2 is not available, Sub Stream 1 will work too, but usually has a lower resolution - in this case you can skip the TetherX steps below.
    ​

  3. Choose either H.264 Baseline (preferred) or H.264 Main as the Encode Mode. On some camera models you will see H.264B.
    ​

  1. For the best performance vs. quality balance, set the Resolution to 720p or 1080p.

  2. Set the Frame Rate (FPS) between 4 to 6 fps.

  3. Select VBR as the Bit Rate Type.

  4. Set the Bit Rate to 1024Kb/s for 720p and 1792Kb/s for 1080p.

  5. Set the I Frame Interval to double the framerate, such as 8 or 12.

Note: Some models may not have the Code-Stream Type option, which is not essential.

Inside TetherX

Please note if you have not enabled Sub Stream 2 above, please skip this step:

  • Click on Admin (top right) -> Cameras.

  • Click on the pencil icon to edit the camera.

  • Switch to the Advanced tab.

  • Under the Analytics URL, enter:
    ​/cam/realmonitor?channel=1&subtype=2
