Nefsis is capable of sharing video at resolutions up to 1080p. Please see this section in our Online User Guide for information on changing individual video resolution within a Nefsis conference: https://www.nefsis.com/manual/cc-video-resolution.html. Maximum video resolution can be configured on a per-conference basis by the conference owner. In some cases, the Nefsis client will determine that the system is not capable of video capture at a higher resolutions and it will disable those higher resolutions so that the user's conference experience is not degraded.

We do not currently provide SIP integration in Nefsis, but this is a planned feature. Look for an announcement regarding this capability in the future.

It could be a combination of multiple factors. When you right click on your video in the conference and mouse over the Resolution menu, are additional resolutions above 640x480 visible but not selectable, or is 640x480 the highest resolution listed?

Were you able to select and use the higher resolutions available on the camera?
