Andy,
I purchased two of the SD4A425DB-HNY cameras from your Amazon store in July of 2023. They have worked well after initial setup. Several months ago, I noticed problems while viewing the video from the user interface. Any window sized less than full screen was black. If I double-click the window to full screen I can see the image. Normally I use Microsoft Edge for a browser but have the same problem with either Chrome or Firefox. I do have the plugin installed, websocketserver.exe. As near as I can tell, it is version 5.0.412649.0.

I recently noticed a new firmware was available for installation through the user interface.

I have not installed the new firmware. Need to check with you to see if the new firmware would resolve the video viewing problem?
Is there a newer web socket server included with the new firmware?
Are there any particular problems with the new firmware?
Please advise.
