Not that easy. Takes time. Good firewalls (like pf or ipfw) are hard
to beat.
Scanners sometimes go just for privileged ports, aka 1-1024. Further,
if your camera is behind the router, it has private address, which is
not available from outside. Intruder has to run through nat first, using
open port, that accepts two way communication. Or shoot blindly
into open port and wait to see what would happen. If you have no
application that listens on the port, nothing could harm you. When
the port is receiving data, it is a matter of having the latest version,
with all security patches up to date.
To say it simply: on your local net, you cannot be seen from outside,
except you broke security.
Best regards.
