Isn't it illegal to access a system through a password without permission in Australia?
And aren't there large fines/jail time if you mess with the settings or stored data having broken in?
Just because somebody hasn't changed the default password doesn't make it legal.
...So posting that you have done it doesn't seem wise, especially on Facebook!
Don't think many of us have anything on our cameras to hide so changing the default password is only necessary to prevent criminals messing up our settings, and in many countries hacking is a criminal offence, and one you don't want on your record, so don't do it!
