Streaming

You can stream the camera/playback video and audio of the unit with low latency.

Two streaming methods are supported.

  • RTMP/RTMPS streaming

    You can stream the camera video and audio of the unit with low latency using RTMP (Real Time Messaging Protocol) developed by Adobe Inc. RTMPS which uses SSL encryption is also supported.

  • SRT streaming

    You can stream the camera video and audio of the unit with low latency using SRT (Secure Reliable Transport) developed by Haivision. SRT streaming employs a listener and a caller. The listener has connection destination information, such as an IP address and domain. The caller connects to the listener. The unit corresponds to a caller.

The streaming bit rate range and initial value varies depending on the system frequency and resolution as follows.

System frequency Streaming
Resolution Bit rate range (Mbps) Initial value (Mbps)
59.94/50 3840×2160 38 only –
1920×1080 4.5 to 27 9
1280×720 2.3 to 13.5 6
29.97/25/23.98 3840×2160 13 to 38 34
1920×1080 3 to 18 6
1280×720 1.5 to 9 4

    The default certificate is imported into the unit.

    When loaded successfully, a message appears.

Reverting to the built-in default certificate of the unit

Select [Network] – [Stream] – [RTMPS Default Certificates] – [Reset] – [Execute] in the full menu.

When the operation is completed successfully, a message appears.

The replacement default certificate is deleted and the built-in default certificate of the unit becomes enabled.

Checking the default certificate status

Select [Network] – [Stream] – [RTMPS Default Certificates] – [Status] in the full menu to display the status of the default certificate.

When the built-in default certificate of the unit is being used, [Preinstall] is displayed.

When a replacement default certificate is being used, the date and time that the certificate was replaced is displayed.

Starting streaming

  1. Connect the unit to the Internet or local network.

    Note

    • Use of wired LAN is recommended since streaming requires a large volume of continuous communication. If using the 2.4 GHz band wireless LAN, remote control from mobile devices or Bluetooth remote control operations may be disrupted. If the use of a wireless connection cannot be avoided, conduct sufficient testing beforehand in a radio wave environment similar to the actual usage environment.
  2. Select the transfer settings configured beforehand on the [Stream] status screen or using [Network] – [Stream] – [Destination Select] in the full menu.

  3. Set [RTMP/RTMPS Status]/[SRT-Caller Status] on the [Stream] status screen or set [Network] – [Stream] – [Setting] to [On] in the full menu.

    Streaming starts with the configured settings.

Note

  • Streaming cannot be started in the following cases.

    • When [Shooting] – [S&Q Motion] – [Setting] is set to [On] in the full menu
    • When [Project] – [Rec Format] – [Frequency] is set to [119.88]/[100] in the full menu.
  • Once you start streaming, it may take several 10s of seconds before video/audio actually start streaming.
  • If the streaming connection destination settings are invalid or if a network connection has not been established, “×” is displayed by the streaming status indicator.
  • Video/audio data are sent as-is via the Internet. Accordingly, the data may be accessible by other parties. Make sure that the connection destination is able to receive the streaming data. Data may be sent to an unintended party due to an error in the address settings or other reason.
  • Streaming may be interrupted, depending on your internet connection or network conditions. If this occurs, start streaming again.
  • The image quality may be adversely affected for fast-moving scenes.
  • You may not be able to play all frames if streaming at high resolution and low bit rate. To reduce this phenomena, select a lower resolution in [Resolution].
  • The video cannot be viewed using the “Monitor & Control” application during streaming.
  • File transfer is not supported during streaming. File transfer is supported after stopping streaming.
  • If streaming is started during file transfer, the file transfer stops. File transfer restarts after stopping streaming.
  • The screen information update frequency is reduced during streaming, but this does not affect operation.
  • The recording settings cannot be changed during streaming.
  • The distribution formats available for streaming vary depending on the [Rec Format] of the main signal.
