The short answer is: No.
That setting is about the local camera, for example a camera built-in or connected via USB, to your computer. You are about a remote camera, the camera in your door-bell. Even if you could use that as source, it would be displayed to your caller – in your case the one who rang your bell.
When somebody rings your bell, you get an incoming call in Jitsi Desktop. Right? Then you accept that call and talk. Right? Therefore, we have to check, why Jitsi Desktop is not able to display the (SIP-) video offered by your camera. For this, I mentioned that Wireshark approach. If you have an issues with that, please, do not hesitate to ask.
Unfortunately, you did not answer my question about which version you use. The nightly builds do not offer incoming video, because of a software bug. Therefore again, are you using Jitsi Desktop 2.10? When you do not answer questions, you make it difficult to help.
