If you have YIPC installed, open it then locate the lower-left area and click the plus sign. A new window will open allowing you to add the cameras to the database. Press ADD and then type the username and password. Keep in mind that you can view the cameras that are connected to a local network. You can't browse the ones that are at a remote location on another network. You might need to create a link between your network and the other networks (typically through VPN) in order to search for cameras. If you are connected to the same network, click the Open Search Tools in the Add window and the cameras will be detected automatically.
