Configuring the Axxon Camera mobile client on Android OS

Go to the mobile application settings by clicking the button or on the information panel .

The screen with the following settings will open:

• Connection—the streamer mode and its settings.
• Video parameters—the transmitted video settings.
• Help—language and version of the application.

Streamer settings (Connection)

The mobile client has two modes of video transmission: RTSP server mode and RTMP mode.

To select a mode, click on the Streamer mode area:

Video transmission in RTMP mode

To transfer video from the Android device camera to the Axxon PSIM/Axxon One server in the RTMP mode, do the following:

On the server that will receive the stream:

1. Make sure that ports 1935 and 8554 on the computer are not blocked by the firewall and are not occupied by other software. These ports are used by default for RTSP data transmission, and are also used as an example in this instruction.

2. Download the latest version of the mediamtx service from GitHub and run mediamtx.exe.

   Attention!

   The devices on which the mediamtx service is running, the video server and the mobile client must be within the same network.

   The mediamtx service receives video streams from mobile devices via RTMP and sends the video to the server in the form of RTSP streams.
   The service indicates the ports it uses, for example:

   2023/09/01 15:11:10 INF MediaMTX v1.0.1
   2023/09/01 15:11:10 INF [RTSP] listener opened on :8554 (TCP), :8000 (UDP/RTP), :8001 (UDP/RTCP)
   2023/09/01 15:11:10 INF [RTMP] listener opened on :1935
   2023/09/01 15:11:10 INF [HLS] listener opened on :8888
   2023/09/01 15:11:10 INF [WebRTC] listener opened on :8889 (HTTP)
   2023/09/01 15:11:10 INF [SRT] listener opened on :8890 (UDP)

   Ports and other settings can be changed in the mediamtx.yml configuration file located next to the mediamtx service executable file.

In the mobile client:

1. In the Connection settings group, enable the RTMP streamer mode.

2. In the Streamer settings, enter a URL of the form rtmp://<IP address>:<Port>/stream_id to which the video will be sent. Example:

   rtmp://192.168.1.1:1935/stream

   where:

   • 192.168.1.1 is the IP address of the computer where the mediamtx service is running;

   • port 1935 is the port that is used by the service to receive RTMP streams;

   • stream is an arbitrary unique identifier for the video stream from this mobile client.

On the server side that will receive the stream:

1. Add a single-channel RTSP device to Axxon PSIM/Axxon One (for Axxon PSIM, see Configuring multimedia receipt using RTSP protocol; for Axxon One, see Configuring connection of devices via RTSP).
2. For this device, set a URL of the form rtsp://<IP address>:<Port>/stream_id, which contains:

   1. IP address of the computer where the mediamtx service is running;

   2. port that is used by the service to send RTSP streams;

   3. unique identifier for the video stream from this mobile client.
      Example:

      rtsp://192.168.1.1:8554/stream

Video transmission in RTSP server mode

To use a mobile device as an RTSP server, do the following:

In the mobile client:

1. In the Connection settings group, enable the RTSP server mode.
2. If necessary, change the RTSP server port. The default port is 1935.
3. The mobile client displays the URL for setting up a connection to Axxon PSIM/Axxon One. To copy it, click on the RTSP server url area.

On the Axxon PSIM/Axxon One server:

1. Create a video capture device operating over the RTSP protocol (for Axxon PSIM, see Configuring multimedia receipt using RTSP protocol; for Axxon One, see Configuring connection of devices via RTSP).
2. In its settings, specify the URL copied from the mobile client.

Video parameters

By default, the mobile client uses the following parameters for transmitted video:

• Main camera resolution: 1920x1080
• Front camera resolution: 1920x1080
• Bitrate: 1 Mbps
• FPS: 30

You can change these parameters in Settings → Video parameters.

Application language

By default, the application language is the same as the device's operating system language. You can change it in Settings → Help → Language.
