Definitely will be useful to have this - setting up the motion detection would be much easier when you can see what's triggering it.

Would like to add my support for this - would like to be able to share individual cameras on an NVR to specific users.

The whole user thing could do with being a bit more granular - it's good to have some "presets" (like the current Admin/User roles) but to have a way to customise each user's access more will definitely help.
