Delay in retrieval of snapshot causes generic icon

[grubis]

I'm just exploring this issue, but I'm using the Home Assistant qvrpro integration, which uses this Python Library. I've noticed that some snapshots come back with a generic camera icon instead of a snapshot.

I believe what's happening is that QVRPro established a connection to each camera on invocation and returns the picture. When the connection to the camera is slow (like a WiFi EZVIZ doorbell camera), the function times out before the snapshot can be acquired.

You can test this in the Windows QVRPro Client by having your mouse hover over each camera in your list of cameras on the left side of the page. When you hover over a camera, it grabs a snapshot. Some cameras take longer to respond than others, and there is a correlation between the delay and if the snapshot is successfully retrieved by this library.

I've applied for the QVRPro API access so maybe I can dig further.
