Camera-Viewer EX can search for display units on the network. For a display unit to be searchable, its IP address must be on the same subnet as the computer running Camera-Viewer EX, and the display unit must be able to receive broadcasts on the network.
When there is a router or firewall between the computer and display unit, searching for display units may not work.
For details about the IP address setting and your network environment, please ask your network administrator.
