How can I remotely determine if a laptop has webcam from the console?

Question

I have multiple laptops I can remote into, but I do not know whether they have a working webcam. I cannot see them. I do not need to access the webcams; I just need to know if one is present.

Is there a way to remotely tell whether a laptop has a webcam?

I would prefer some sort of cmd code that I can trigger on each to quickly give me a copy-able printout of such information to compile across computers.

Need far more information. Are these on a domain? Are you an admin? — Keltari, Feb 14 '23 at 15:08
I'm just a user with local admin rights on our research computers. We have computers set up in multiple locations. Using VPN, I can access local accounts on each machine using remote desktop. — theforestecologist, Feb 14 '23 at 15:12

On Windows, you can look in Device Manager to check whether camera devices exist. This check can also be performed using PowerShell or Command Prompt, without special rights.

Command Prompt:

pnputil /enum-devices /class Camera /connected

Will print:

PowerShell:

Get-PnpDevice -PresentOnly -Class Camera

Will print:

You cannot reliably distinguish internal and external cameras using trivial filters (as shown above). You’ll have to go by the name or other hints.

Some older webcams which do not use the USB Video Class may not appear in the Camera class. Instead, the could be using the Image class, which today is usually used for document scanners and the like.

With pnputil, you’ll have to run two commands to get both classes. With PowerShell, you only need one:

Get-PnpDevice -PresentOnly -Class Camera,Image

Output (different PC, without -PresentOnly, hence the Unknown):

Status     Class           FriendlyName                                                                     InstanceId

However, again, this only applies to very old hardware and it will also catch non-camera devices, like the multi-function printer above.

I suspect nearly every 'laptop' webcam's connected via USB. In theory a RPi style direct connection is possible but its something that I've never seen in the wild - which is likely why there's no 'obvious' difference — Journeyman Geek, Feb 14 '23 at 15:19
Note: Both of these commands only show the internal camera on my laptop, not the external one connected by USB. — Gerald Schneider, Feb 15 '23 at 07:22
They do show any external camera devices, as visible in the example output. — Daniel B, Feb 15 '23 at 09:06
Not on my machine. I'm not saying the command is wrong, I'm just saying you should not rely on it to show all devices that are actually connected. There could be more. My Logitech webcam is registered as class "Image" instead of"Camera". — Gerald Schneider, Feb 15 '23 at 11:14
Modern webcams, which all use the USB Video Class (UVC), will show up in the _Camera_ class. You are right that older cameras with proprietary drivers may show up in the Image category. I’ll adapt my answer. — Daniel B, Feb 15 '23 at 19:04

PowerShell looks like a good option. From Use PowerShell to discover laptop webcam a couple of options are given.

The one that worked for me is

Get-CimInstance Win32_PnPEntity | where caption -match 'cam'

You may have to run the command a few times with variations of "camera" or "cam" or other terms that can catch all the various options. My camera for example is a Microsoft LifeCam that will not be seen if you search for "camera"

You might be able to see more if you modify your search to look for

Get-CimInstance Win32_PnPEntity | where PNPClass -match 'Image'

Which would show you all imaging devices and may include scanners and other devices.

The first command is the only one listed here that shows both of my cameras, internal and external; the second command only shows my external cam, but not the internal. — Gerald Schneider, Feb 15 '23 at 07:23

I haven't extensively tested this but

Get-PnpDevice -PresentOnly | Where-Object { $_.Class -match '^Camera' } seems to work - kinda started with this SO answer and adjusted to fit

It'll also give you the name of the camera model under 'friendly name'

I tested it on an external one - two actually and it works fine – Journeyman Geek Feb 15 '23 at 07:34
