You can use the Update FingerPrint option for the device that are already profiled. (For e.g. Devices that are profiled as generic/unknown/etc).
Subnet scan would help you to profile the static devices in the network.
Try configuring the subnets under Configuration >> Profile and network Scan.
You may also try adding the Camers under Guest Devices and allow access using the [Guest Device Repository] as auth source, if the numbers are low.
