Open Powershell and run the following cmdlet:
Get-PnpDevice -Class 'USB' | ft

Look in the "Friendly Name" column.
The webcam(s) may be listed in some identifiable/traceable manner. For example, my Logitech Pro 9000 at the second line.
However, as can be seen above, the results can be Unknown/generic. AKA: "no name".
