+In order to take actions on cameras directly (such as change the LED
+state on a UVC Micro or get a snapshot from the camera) you need to
+set the admin password for it. The NVR tells us the username, but we
+must store the password. To do this::
+
+ $ uvc --name Porch --set-password
+ This will store the administrator password for a camera
+ for later use. It will be stored on disk obscured, but
+ NOT ENCRYPTED! If this is not okay, cancel now.
+
+ Password:
+ Confirm:
+ Password set
+
+Then you can do things like get a snapshot from the camera directly::
+
+ $ uvc --name Porch --get-snapshot > foo.jpg
