How to add RTSP camera without username/password

My rtsp enabled cameras do not require a username and password. I am able to view their streams perfectly @ rtsp://192.168.1.1:7447/a1b2c3
CamSync requires that I input a username and password with the camera information.
How can I just enter my rtsp address with using a username and password?

Most cameras have a standard login and password admin/admin Or root/12345678 Perhaps it is enough to indicate something like this.
And perhaps for security purposes, it requires you to come up with a login and password even if the camera does not have one
