Comparisons · A phone used as a webcam through Windows 11, against a dedicated USB webcam

Use your phone as a webcam, or buy one? What Windows 11 documents, and what it does not

Before buying a webcam it is worth knowing that Windows 11 has a built-in alternative: Microsoft states that "you can now use your linked Android device's camera as a webcam for PC applications", enabled by a single toggle called "Use as connected camera". The requirements are published - a PC running Windows 11 or later, an Android device running Android 10 or later, the Link to Windows app at version 1.24022.0 or later, and, for linking at all, both devices on a Wi-Fi network. What is not published is just as decision-relevant: on the pages captured on 2026-09-19 Microsoft gives no resolution, frame rate, field of view or latency figure for this path, and mentions no iPhone or iOS support. A dedicated webcam is the opposite - Logitech publishes the resolution and frame-rate pairs, the field of view, whether the focus is fixed and which port it needs. And one job is settled outright: Microsoft requires an infrared camera for Windows Hello face sign-in, so a phone cannot replace a Hello-capable webcam. This guide sets the two out side by side, with the setup steps and the documented failure modes.

Who this guide is for and what to prepare

People about to buy a webcam who want to know whether the phone in their pocket will do
People who enabled the connected camera and cannot see it, or whose phone never asked for permission
People who need face sign-in or a fixed, always-ready camera and need to know where the phone route stops

What you need

The Windows version of the PC, and the Android version of the phone
The Link to Windows app version on the phone (Microsoft states 1.24022.0 or later for the camera feature)
Whether both devices are on the same Wi-Fi network, which Microsoft lists as a requirement for linking

1. What Windows 11 publishes about using a phone as a camera

Microsoft states the feature plainly: "You can now use your linked Android device's camera as a webcam for PC applications." It then lists the requirements as "a PC running Windows 11 or later", an "Android device running Android 10 or later" and "Link to Windows app version 1.24022.0 or later". The linking itself has its own published conditions on the companion page: a PC running Windows 11, an Android device running Android 10 or later, and "your phone and PC both need to be connected to a Wi-Fi network".

Enabling it is one toggle. Microsoft's steps are to open Settings, go to Bluetooth & devices, scroll to Mobile devices, add the device if it is not linked yet, then "select the device and toggle on Use as connected camera". The same feature appears in the Manage devices list, where Microsoft describes it as "make your mobile device's camera available as a webcam to apps". After that, Microsoft says the phone "will appear as an available camera option in Windows Settings and other camera applications", and that you change which camera an application uses "directly from the app's settings".

Linking a phone for the first time is a QR-code flow: turn on "Allow this PC to access content and capabilities from your mobile devices", select Add device, scan the QR code shown on the PC with the phone, and grant the permissions the phone asks for. The camera toggle is one item in a list of feature toggles, so enabling the camera does not oblige you to enable file access or photo notifications - the same Settings page controls each separately. The wider Phone Link setup, notifications and photo transfer are covered in our separate article on Windows 11 phone linking rather than repeated here.

Two documented behaviours explain most first-day confusion. Microsoft says a permission prompt appears on the phone because "to connect your phone's camera to your PC, we need permission to access it", and that if you do not see it, you should "check your video preview - if you see a black placeholder image with a white icon, look at your taskbar for a new window with a camera icon", or set it manually by going to the phone's Settings, finding Link to Windows in the app list and turning camera permissions on. It also notes that the image follows the phone's orientation, so if the picture does not rotate you should check whether rotation lock is on.

1. What Windows 11 publishes about using a phone as a camera
Item	What Microsoft publishes	Where
PC requirement	A PC running Windows 11 or later	Use your mobile device's camera
Phone requirement	Android device running Android 10 or later	Both the camera and the linking pages
App version	Link to Windows 1.24022.0 or later for the camera feature (1.23112.189 or later for linking)	The two support pages differ by feature
Network	"Your phone and PC both need to be connected to a Wi-Fi network"	Manage mobile devices in Windows
The setting	Settings > Bluetooth & devices > Mobile devices > select the device > "Use as connected camera"	Use your mobile device's camera
Choosing it in an app	It appears as a camera option; change the camera from the app's own settings	Use your mobile device's camera

2. What is not published, and why that matters before buying

The pages above describe what the feature does and how to switch it on. They do not contain a single image-quality figure. On the two Microsoft pages captured on 2026-09-19 there is no resolution, no frame rate, no field of view and no latency figure for the connected camera - the words simply do not appear. That is not a criticism of the feature; it means you cannot compare it with a product specification, and anyone who tells you it is "4K because the phone is 4K" is stating something no published document supports.

The scope is also narrower than people assume. Both pages are written about Android: the camera page says "your linked Android device's camera" and lists an Android version requirement, and neither page mentions iPhone or iOS anywhere in the text captured. If you carry an iPhone, treat this route as unconfirmed on these documents rather than as available.

A dedicated webcam is the opposite case: the numbers are all published. Logitech states 1080p at 30 fps with a fixed 58-degree field of view and fixed focus for the Brio 100; 1080p at 30 fps, 78 degrees and autofocus for the C920s; 1080p at 30 fps or 720p at 60 fps with a selectable 90, 78 or 65 degrees for the Brio 500; and 4K at 30 fps or 1080p at 60 fps, 8.5 MP and a Sony STARVIS sensor for the MX Brio. Whatever you think of those figures, you can compare them with each other and with what your meeting software will actually transmit.

There is also a job the phone route cannot do at all. Microsoft's Windows Hello setup page describes face sign-in as configured "with your PC's infrared camera or an external infrared camera", and its article on third-party devices states that "Enhanced sign-in security is not supported for external camera modules". A phone appearing as a camera to applications is not an infrared Windows Hello sensor, so if sign-in is part of why you want a camera, that decides it - our separate guide on Windows Hello covers the fingerprint and IR-camera options.

2. What is not published, and why that matters before buying
Question	Phone as a connected camera	Dedicated webcam
Resolution and frame rate	Not published on the Microsoft pages captured	Published per model (for example 1080p/30, or 4K/30 and 1080p/60 on the MX Brio)
Field of view	Not published	Published (58 degrees fixed on the Brio 100; 90, 78 or 65 selectable on the Brio 500)
Focus	Not published	Stated as fixed focus or autofocus per model
Platform	Android only on these pages; no mention of iPhone or iOS	USB, independent of any phone
Windows Hello face sign-in	No - Microsoft requires an infrared camera	Only models that state infrared and Windows Hello support
What it costs to try	Nothing beyond the app and the toggle	A purchase

3. The practical differences the documents imply

Availability is the first one. The phone route depends on a linked phone that is charged, nearby and on the same Wi-Fi network - Microsoft lists the network condition for linking - and on that phone not being needed for something else during the call. A USB webcam is attached to the monitor and is available whether or not the phone is in the room. Neither is better in the abstract; they fail in different ways.

Mounting is the second. Microsoft documents that the image follows the phone's orientation and that rotation lock stops it rotating, which is a hint about how the feature is used in practice: the phone has to be held somewhere, at the right height, without falling over. A webcam ships with a clip designed for the top of a monitor. If you do go the phone route, the mount is the part you will actually end up buying.

Audio is the third, and it is easy to overlook. Webcam makers publish microphone specifications - Logitech states an omnidirectional microphone picking up to 1 m on the Brio 100, stereo microphones to 1 m on the C920s, to 1.22 m on the Brio 500 and dual beamforming microphones to 1.2 m on the MX Brio. The Microsoft pages describe the phone feature as a camera for apps and say nothing about routing the phone's microphone, so plan your audio separately; our separate guide on headsets and microphones covers that side.

Finally, what the meeting software does with any of this is a separate ceiling. Zoom publishes that group HD video is 720p for the active speaker and that 1080p requires an eligible plan plus activation and hardware conditions; Microsoft publishes that Teams optimizes to at most 1080p and 30 fps and drops to much lower resolutions when bandwidth is limited. Our webcam selection guide goes through those figures in full - the short version is that a better camera does not automatically become a better picture at the other end.

3. The practical differences the documents imply
Aspect	Phone as a camera	Dedicated webcam
Availability	Needs a charged, nearby, linked phone on the Wi-Fi network	Always on the monitor, independent of the phone
Mounting	Your problem; orientation follows the phone and rotation lock affects it	Clip or stand supplied with the product
Microphone	Not described on the Microsoft camera page	Published pickup range per model (about 1 m to 1.22 m on the Logitech models cited)
Face sign-in	Not possible; Hello needs an infrared camera	Possible only on models that state infrared support
Cost to evaluate	Free - enable the toggle and look at the preview	Buy first, judge second
What the meeting app sends	Governed by the service, not the camera	Same - see the webcam guide for Zoom and Teams figures

4. A decision you can make in ten minutes

Try the free route first, because it costs nothing and it answers the question with your own face, your own room and your own lighting. Check the three published requirements (Windows 11 or later, Android 10 or later, Link to Windows 1.24022.0 or later), link the phone, enable "Use as connected camera", then open the Windows Camera app or your meeting app and select the phone from the camera list. If the preview is good enough at the height you can actually mount the phone, you have saved a purchase.

Buy a webcam when one of the documented gaps matters to you: you need Windows Hello face sign-in, which Microsoft ties to an infrared camera; you need a camera that is always in place without setting up a phone; you need a published field of view because of how much of the room you want in shot; or you need the microphone specification that comes with the product. Those are decidable from documents rather than from opinion.

If the phone route misbehaves, work through Microsoft's own list before concluding anything: confirm the app version and the Android version, confirm both devices are on Wi-Fi, look for the permission prompt on the phone, and if the preview shows "a black placeholder image with a white icon", look in the taskbar for the new window with a camera icon that guides you through granting access. Permissions can also be set manually in the phone's Settings under Link to Windows. If a background is covering the image, Microsoft's answer is to disable the background in the app you are using.

One last point that applies to both routes. Windows keeps per-camera settings, and Microsoft notes that applications may apply their own settings at any time and that not every app uses the Windows defaults - so if a call looks different from the preview, the app is the place to look. Our webcam selection guide covers those camera settings and the meeting-service ceilings in more detail.

4. A decision you can make in ten minutes
If this is true for you	Choose	Why, from the documents
You have an Android phone on Windows 11 and just need calls to work	Try the phone first	The requirements and the toggle are all Microsoft asks for
You want face sign-in as well	A webcam that states infrared and Windows Hello	Microsoft ties face sign-in to an infrared camera
You use an iPhone	Treat the phone route as unconfirmed	The Microsoft pages captured describe Android only
You need a specific field of view	A webcam	Published per model; not published for the phone route
You want the camera always ready	A webcam	The phone route needs a charged, linked phone on Wi-Fi
You need a microphone with it	A webcam, or a separate microphone	Pickup range is published per webcam; the phone page does not describe audio

Limitations and requirements

The requirements, steps and quoted phrases are as published on the Microsoft support pages captured on 2026-09-19, and the webcam figures are from Logitech product pages captured in this sprint. Microsoft's pages change as the feature develops, and version numbers in particular are the kind of detail that moves; check the same pages before relying on them.
The statement that Microsoft publishes no resolution, frame rate, field of view or latency for the connected camera is an observation about those two pages as captured, not a claim that the feature performs badly. Nothing here was measured by this site: no call was made, no camera was tested, and no image-quality comparison is offered.
This guide does not cover using a phone as a webcam through third-party applications, which have their own requirements and privacy implications. It also gives no prices; whether a webcam is worth buying depends on figures you can read and on how you will mount a phone, not on a number this site could supply.

Frequently asked questions

What exactly do I need for Windows 11 to use my phone as a webcam?

Microsoft lists three requirements for the camera feature: "a PC running Windows 11 or later", an "Android device running Android 10 or later", and "Link to Windows app version 1.24022.0 or later". Linking the phone at all has its own published conditions on the companion page - a PC running Windows 11, Android 10 or later, and "your phone and PC both need to be connected to a Wi-Fi network" - and is done by opening Settings > Bluetooth & devices > Mobile devices, turning on "Allow this PC to access content and capabilities from your mobile devices", selecting Add device and scanning the QR code with the phone. Then select the device and toggle on "Use as connected camera". After that Microsoft says the phone appears as an available camera in Windows Settings and other camera applications, and that you switch cameras from within each app's settings.

Is the picture as good as a webcam?

Nobody can tell you from published documents, because Microsoft does not publish one. On the two support pages captured on 2026-09-19 there is no resolution, frame rate, field of view or latency figure for the connected camera at all. Webcam makers do publish those: Logitech states 1080p at 30 fps with a fixed 58-degree field of view and fixed focus for the Brio 100, 1080p at 30 fps with autofocus and 78 degrees for the C920s, and 4K at 30 fps or 1080p at 60 fps for the MX Brio. The practical consequence is that the phone route has to be judged by looking at it - which costs nothing, since the feature is a toggle - while a webcam can be judged from its specification before you buy. Remember too that the meeting service imposes its own ceiling: Zoom publishes 720p for group HD video and conditions for 1080p, and Microsoft publishes up to 1080p and 30 fps for Teams.

I turned the setting on but my phone never asked for permission and the preview is black.

Microsoft documents this case. It says to check the video preview: "if you see a black placeholder image with a white icon, look at your taskbar for a new window with a camera icon", and that window lists your phone name and guides you through the next steps. To set the permission by hand, go to the phone's Settings, find Link to Windows in the list of apps and make sure camera permissions are turned on; if the stream does not resume by itself, use the button in that window to refresh. Also confirm the published requirements - Android 10 or later and Link to Windows 1.24022.0 or later - and that both devices are on a Wi-Fi network, which Microsoft lists as a condition for linking. If the image is there but does not rotate when you turn the phone, check whether the phone's rotation lock is on.
