The idea is great, there are several proposals for further implementation, making 2 streams for each camera, one in a small view, the second in full screen, keeping several cameras in high resolution at once is quite resource-consuming.
I wish the names could be written in Russian.
Turn on and off the sound in cameras.
Make images stretch across the width and height of the window
Ability to specify width and height in the camera settings (I saw that this can be done in the config file, but I would like it in the interface)
Well, in the end, check for updates, at least manually or when turned on
