Cameras Discovery:

Camera Search

Image Credits: https://kintronics.com/ip-camera-systems-professional-versus-consumer-systems/

What is Cameras Discovery?

  • Idea is to convert it from a library to a quickly-digestible tool including some other handy services & discovery options.
  • Support for searching via other mechanicsms like UPnP,mdns,port number based to get list of all potential cameras.

Features?

  • DiscoverCameras : discover cameras in your network. Supported scan types are Upnp, RTSP Port scan, Onvif.
  • GetMp4stream : gets you the rtsp or other similar url to web play-able mp4 stream.
  • Probestream : Probe a stream by giving URL as parameter. ffprobe response is returend as json giving details like
  • Stream-ops : Pass a streamURL,
    • Save the video file from stream locally.
    • Respond with html video tag playable stream. (via /mp4stream)
    • Save the video file from stream on cloud.
    • Get Image file from stream as Response. (One shot usage)
    • Get Image Steam from given stream as Response. (BULK USAGE)
    • Restream the resource locally or on cloud.
    • Access the stream via websocket.
    • Access the stream on HLS.
  • Health check call for camera via strategies:

Running:

  • Run docker directly:
docker run --rm --name=camerasdiscovery -p 8000:8000 --network host saurabhshandy/camerasdiscovery
#OR 
bash run.sh
  • Only Pullling docker image
docker pull saurabhshandy/camerasdiscovery

Dockerhub : Link

Routes with Input & Output:

List of Routes:

  • /discoverCameras : discover cameras in your network.

    Code:

    curl --request GET \
    --url http://localhost:8000/v1/rpc/discoverCameras \
    --header 'content-type: application/json'

    Sample Output:

  • /mp4stream : Returns a web play-able mp4 stream so that you can embed this as src in your video element and play the video simply. The request takes 3 params.

    • camerastream : pass uriencoded(EncodeURIComponent) stream link; ex: rtsp://192.168.x.y/live/av0?user=myuser&passwd=mypassword
    • ttl: time duration for which you want the stream to be running in seconds; ex: 600s i.e 10minutes.
    • width: the width of the video you want; ex: 720 pixels. ffmpeg conversion in the function takes care of the above params to give you html video tag embeddable video off the bat.
    Code:

    curl --request GET \
    --url http://localhost:8000/v1/rpc/mp4stream?camerastream=rtsp%3A%2F%2F192.168.x.y%2Flive%2Fav0%3Fuser%3Dmyuser%26passwd%3Dmypassword&ttl=600&width=720 \

    Sample Output:

  • /streamops : Do operations on video stream/file like saving it locally/cloud or restream it.

  • /getstreams : Get rtsp stream URL for Onvif Cameras. Accepts list or single Onvif Object.

    Code:

    curl --request POST \
      --url http://localhost:8000/v1/rpc/getstreams \
      --header 'content-type: application/json' \
      --data '[
      {
      "xaddr" : "http://192.168.1.99:36000/onvif/device_service",
      "user" : "username",
      "pass" : "password"
      },
      {
      "xaddr" : "http://192.168.1.113:36000/onvif/device_service",
      "user" : "username",
      "pass" : "password"
      }
    ]'

    Sample Output:

    [
      {
        "xaddr": "http://192.168.1.113:36000/onvif/device_service",
        "user": "admin",
        "pass": "admin",

        "pass": "admin",
        "url": "rtsp://192.168.1.99:554/live/av0?user=admin&passwd=admin"
      }
    ]

  • /sampleurls : Don't have streams ?? This route will give you stuff to play around.

    Code:

    curl --request GET --url http://localhost:8000/v1/rpc/sampleurls

    Sample Output:

    [sampleurls.json](https://github.com/beyondszine/camerasdiscovery/blob/master/routes/sampleurls.json)

  • /getimage : Get only one image for the requested stream. (Don't abuse this route too much. For getting multiple snapshots in fast manner, use getimagestream).

    Code:

    curl --request POST \
      --url http://localhost:8000/v1/rpc/getimage \
      --header 'content-type: application/json' \
      --data '{
      "url" : "rtsp://192.168.x.y/live/av0?user=myuser&passwd=mypassword"
    }'

  • /getimagestream : This enables to get recurring images in case you want image stream.

    Code:

    ## Nothing yet.

  • /liveliness : This method is to check the liveliness of the cameras. Three strategies are put in place.

    Code:

      # req.body must be json of following schema
      {
        "strategy": "portknock",
        "camerasList": [{
          "address": "192.168.0.109",
          "port": 554
        }]
      }
    
      # response.body must of  
      [
        {
            "status": true,
            "address": "192.168.0.109",
            "port": 554
        }
