Just a few more defaults while poking around Shodan!
The Technicolor TG582n has a default according to the manual:
The default password is either blank or the ACCESS KEY printed on the label of your Technicolor Gateway. This depends on the settings chosen by your Service Provider
After connecting to the unit and beginning a terminal session, a login screen appears. The default password for the ATLAS 550 is (all lowercase) password.
MayGion IP cameras (Shodan search) have a default admin account of admin:admin.
By default, your Network Camera is not password-protected.
The administrator account name is “root”, which is permanent and can not be deleted.
