Device state in UI does not update upon configuration change

Hi,

I am building an integration with Nx Witness V4.0.0.29987 using the system API: /ec2/ and server API /api/

When changing the camera's password using - the following API call:

 

ec2/setResourceParams 

body: [{"name":"credentials", "resourceId":"<cameraId>","value":"<username>:<password>"}]

 

The camera state in the UI remains un-updated until I initiate an action such as view stream. Once the action is initiated the state gets updated. This happens on multiple scenarios such as -

 

setting the wrong credentials in the VMS --> The camera will remain online [instead of Unauthorized] until an action is initiated.

 

When Updating the correct credentials -->the UI side will not show the updated value until an action is initiated [will show Unauthorized instead of online]

 

[I'm using the following API call for getting camera status:

https://<host>:7001/ec2/getStatusList?id=<cameraId>]

 

Is there a "gentle" way to refresh the camera state using the system API: /ec2/ or server API /api/

  Hello Ido,
  
  

  First of all, I'd like to recommend you switching to the latest version of VMS and SDK.

  > Is there a "gentle" way to refresh the camera state using the system API: /ec2/ or server API /api/

  There are two parts of the situation: the Server part, the GUI part.

  Automatically, status tracking is performed if
  - auto discovery is enabled or
  - recording is enabled on a camera

  If you have Enable cameras and servers auto discovery and automated cameras status check the server will periodically (about 1 min) recheck the cameras and update statuses. The GUI will receive a notification from the Server on status change.
  If the recording is on the Server will automatically update the status of the camera.

  If you don't have auto discovery enabled, you need to force the Server to login to the camera and update its status.
  Turning the recording on will make the Server update status of a camera.
