Before a new camera is started by CAMNET server, it must be joined. A joined camera has the Video field in the Access panel set to yes.
Before any changes made in any Cam setup panel are used by CAMNET server for an already-joined camera, the cam.cfg file must be reloaded by CAMNET server. Press the Refresh camera button to have CAMNET server restart the camera connection. This reloads the updated cam.cfg file.
Press the Test button. (Currently, no testing is performed.) If all tests pass, and the camera was not already joined, the Join button becomes active. Press the Join button.
Upon pressing Join, the client tells CAMNET server that a new camera is available, and that this new camera is to be started. The camera's cam.cfg file has everything CAMNET server needs to start the camera.
When making changes to the camera setup, those changes make it to the camera's cam.cfg file after each Save, but the server loads the camera's cam.cfg file only when the camera connection is started. For new cameras -- those which needed to be joined -- the camera was not yet started so the join had CAMNET server start the camera, using the new cam.cfg file. For existing cameras, those that were already started when CAMNET server itself started, the changes made to cam.cfg need to be reloaded by CAMNET server. To force this reload of the cam.cfg file, press the Refresh camera button. CAMNET server disconnects from the camera, reloads cam.cfg, then reconnects (starts) the camera, now using the updated camera configuration.
