Observing
You may not want to control a computer, but merely monitor what is on its screen.
Observing a remote computer is similar to controlling one, except your mouse
movements and keyboard input are not sent to the remote computer. Apple Remote
Desktop client computers can be observed by any administrator computer that has the
“Observe” permission set. See “ARD Administrator Access” on page 38 for more
information about ARD permissions.
Warning: Do not use the same password as any user or ARD administrator. The
password may not be secure.
