To get the camera events using WebSocket, do the following:

  1. Connect to ws://[user_name]:[password]@[IP-address]:[port]/[prefix]/events.
  2. Send a JSON command to subscribe on events generated by the specified cameras (see Get list of video sources ( cameras and information about them)). This subscription allows you to receive all the events shown in the table below.

    Code Block
    {
    "include":
    ["hosts/Server1/DeviceIpint.1/SourceEndpoint.video:0:0", "hosts/Server1/DeviceIpint.6/SourceEndpoint.video:0:0"],
    "exclude":[]
    }

    include - subscribe to the events receiving;
    exclude - disable the events receiving.
