The priority in which the camera title is displayed in IDIS web is as follows:

FAQ WebWatch

1st priority: The title entered through mouse right-click > ‘Change Camera Title’
2nd priority: The tile entered in the Camera Setup > System > Name
※ If both two names are deleted, no title is displayed while IDIS Web is in use.
※ When reconnecting to IDIS Web, if there is no camera title, it is displayed as Camera 1, Camera 2, … etc.

The title entered through the mouse right-click is saved as an ini file in Windows, so you need to delete the ini file to delete the name.
