Adding my name to the list of customers that is frustrated with the black box. At the very least, as someone said upthread, there should be an option for a static image. Using Dial In is not really an acceptable workaround
One thing I wanted to mention along these lines, I’ve bee using Open Broadcast Software (OBS) to change my camera to a picture instead of the black box. It was a very simple setup by just googling the software and then a guide to operate it.
