Dahua Integration Bandwidth Issue

[sdtaheri]

Issue Summary

I'm experiencing a significant bandwidth usage issue when using the Dahua integration in Home Assistant. The NVR model is Dahua DH-XVR5116HS-I3. The NVR is not on my local network, and the internet connection connected to it is limited in bandwidth.

Problem Details

• I can see the streams in HA without issues.
• The problem is that it apparently uses a large amount of bandwidth, as shown in the attached chart.
• The chart shows significant upload traffic on the NVR's network when I have the cameras enabled in HA. The labels on the chart are in Persian, but I can provide further details if needed. Each mark in vertical axis goes up by 1000 MB.
• I have 11 cameras, and all of them are added individually. I am only using the camera stream main entities and not any of the sensor-related functionalities.
• The NVR logs show numerous login/logout entries with the username/password used by this integration, indicating excessive reconnections.

Expected Behavior

• The integration should not keep the streams alive when not actively being viewed or recorded, as this unnecessarily consumes bandwidth.

Steps to Reproduce

1. Add multiple cameras to the Dahua integration in HA.
2. Monitor the network usage on the NVR’s network while the integration is active.
3. Check the NVR logs for excessive login/logout events.

• HA OS: 15.2
