How To Open a Session Via Websocket (CogSocket) With In-sight Vision Suite Cameras

How do I open a session using WebSDK and Websocket?

Answer
To edit values and make other changes via WebSDK (API) using Websocket (Cogsocket), we need to:

• Open a session for a new user (sessionID)
• Log in as a privileged user setup via Insight Vision Suite

To create a new sessionID, we have to connect to the camera via WebSocket using additional software. For testing purposes, Postman can be used.

• Establish connection with camera: <cameraIP>/WS
• Send JSON command:

       {"$type":"post","id":7,"path":"/cam0/hmi/openSession"}

• In reply, we will get:
  {
     "$type": "resp",
     "body": "cam0/hmi/hs/~6130cbbe",
     "id": 7
  }
  where "body" is the SessionID. It will be different every time we send an openSession command.

  

• To log in as an admin, send the command:
  {"$type":"post","id":17,"path":"cam0/hmi/hs/~6130cbbe/login","body":["admin","",false,false]}

In reply, we will get:
