The Ocularis 5 Device Finder works with UPnP and ONVIF by using multicast via UDP. If there are Layer 3 switches on the network, multicast packages may be blocked by default. In this case, the Device Finder will not be able to find devices in other subnets. After the initial broadcast scan, the Device Finder sends a unicast message to the devices in the import file provided.
For the configuration.xml import to work properly, devices must have UPnP or ONVIF enabled. Otherwise, the device will not be recognized by the scan.
