Figure out webcam streaming for space

We have a webcam setup in the main space ( but would like to have at least a webcam in each of the main spaces so people can check on usage of tools before coming in. We have several Waze cams that can be loaded with new firmware to support ( We used to embed it in the website, this works well enough, although breaks occasionally. Problem is we have not figured out a way to make it do multiple cameras. Perhaps there is open source server software that can be used (as I understand our rtsp port gets used by first camera and cant add more)? We are open to buying special purpose cameras if that is the best option. I assume this task will require knowledge of how to configure routers.
