Without SNMP it will be hard to discover the device correctly. If you have a scanserver in the same vlan, then the CDR feature should recognize it as a video device (see https://community.lansweeper.com/t5/scanning-your-network/credential-free-device-recognition-cdr/ta-...). But like I said, this only works when your scanserver is in the same broadcast domain as the device, because it needs at least a MAC address to create a fingerprint of your device.

Most NVR's and other camera equipment support SNMP. Make sure you've set up SNMP correctly on your camera device and configure the corresponding SNMP community under Scanning>Scanning Credentials (don't forget to map the scanning credentials to the scanning target!).
