URL access to snapshot with embedded user/password

Recently acquired a Vistacam 700 to replace an old Foscam IP camera. Trying to access the snapshot image using the URL -

 http://192.168.1.123/img/snapshot.cgi?user=User&pwd=Password

The browser returns with a popup box to enter the user and password.

Is the camera capable of accepting the user and password in the link?

The work around is to disable security.
