Operating Instructions
User Name and Password Protection
The use of a unique User Name and secret Password is an important tool that
will help limit unauthorized individuals from accessing the camera. If you
choose to disable this tool, and choose not to limit access by use of a User
Name and Password, this may result in access to the camera by
unauthorized individuals. (see page 71)
