How to Check Your Camera Before a Meeting on Windows (2026)

The Windows Camera app shows the picture your PC is sending right now. MeetReady checks the camera and the microphone for you on Windows. With the early switch turned on, MeetReady can open two minutes before the event. Press Ctrl+Shift+M for a look at the camera and the microphone. A dark picture or a messy room is easier to fix in a preview. The Camera app shows the picture that Zoom will use on the call.

The Windows Camera app

The Camera app is already on Windows 10 and on Windows 11. The Camera app needs no extra installer on your Windows PC. It does not open Zoom, Teams, or Meet for you.

1. Press the Windows key, then type the word Camera into search.
2. Open the Camera app from those search results on your screen.
3. The Camera app shows a live picture straight from your webcam.
4. Look at your face, the light, and the room behind you.
5. Several cameras can be swapped with the change-camera icon in the Camera app.

Zoom

Zoom shows the picture it will send to the other people.

1. Open the Zoom desktop app from the Windows desktop or Start menu.
2. Click your profile picture in the top corner of the Zoom window.
3. Open Settings, then open the Video page for the live picture.
4. Use the Audio page for the speaker sample in Zoom.
5. Use the Audio page for the microphone sample in Zoom too.

On the Video page you can try a blurred room or another background.

Microsoft Teams

1. Open Microsoft Teams on the Windows PC you use for calls.
2. Open Settings, then open the Devices page for a live picture.
3. Choose Make a test call on that Devices page in Teams.
4. Teams records a short clip, then plays that clip back to you.

The join preview

1. Open a Meet link, then look at the preview ahead of the join button.
2. The gear icon lets you swap the camera and the microphone.
3. You can blur the room or pick another background on that preview.

Meet always shows this preview on the way into the event. Zoom and Teams keep that preview inside their own settings pages.

MeetReady

The three apps above wait for you to remember them. MeetReady is the camera check you can open from a hotkey. The early switch is off at first inside MeetReady on Windows. MeetReady can then open two minutes before the event on your calendar. Ctrl+Shift+M opens the camera and the microphone at any moment. With the early switch off, the hotkey still opens that same look.

PeakFlow Setup 1.6.5 for Windows is a 134 MB installer. The six tools have no time limit and no account. A 14-day Pro trial is included with the PeakFlow download for you. The free tools send no telemetry from your Windows PC. The meeting guide puts this check next to the full-screen alert. The full-screen alert article explains the ScreenSlap timing on its own. The Hand Mirror page compares MeetReady with that Mac camera app.

Light and the room

Sit facing a lamp or a window instead of a bright pane behind you. A bright window behind you turns your face into a dark shape. Daylight at the desk in the morning is not the same light later on. Move around during the preview and watch the edges of the frame. A beer bottle or a messy bed at the edge is part of the picture too. A blurred background in Zoom, Teams, or Meet can cover that room.

The microphone

Most video apps show a moving level as you speak at a normal volume. A flat level means the wrong microphone is selected, or the mute switch is on. Headphones keep room echo from going back into your microphone. MeetReady checks the microphone along with the camera on that PC. The moving level you can watch is inside Zoom or Teams.

A dark camera

Check the USB plug, a closed privacy cover, and any camera key on the laptop. Some laptops have a key that turns the camera off. Try a different USB port on the back of a desktop tower.

1. Press Windows + I, then open the Settings window on your PC.
2. Open the Privacy and security page, then the Camera page in Settings.
3. Turn Camera access on for this PC and for desktop apps.
4. Turn on Let desktop apps access your camera on that same page.

Open Device Manager, then update the camera driver under Cameras there. Remove the camera device in Device Manager, then restart the PC. Close every app that might be holding the camera, including Zoom and Teams. A restart can release a camera that another app left locked. Safe Mode is a way to see whether a startup app blocks the camera. A phone app such as DroidCam or EpocCam can stand in for a dead webcam.

The Google Calendar article is how the event time reaches Windows at all. MeetReady uses the event time only with the early switch turned on.
