Summary: Use Windows PowerShell to discover a webcam attached to your laptop.
How can I use Windows PowerShell to find a webcam or camera that is attached to my laptop?
Use the Get-CimInstance or the Get-WmiObject cmdlet, examine the Win32_PnpEntity WMI class,
and look for something that matches camera in the caption.
By using Get-CimInstance in Windows PowerShell 3.0 or later:
Get-CimInstance Win32_PnPEntity | where caption -match 'camera'
By using Get-WmiObject in Windows PowerShell 2.0:
Get-WmiObject Win32_PnPEntity | where {$_.caption -match 'camera'}
Note Not all webcams populate exactly the same way, so it may take a bit of searching
to find the right string.
