A Mevo Plus radar camera not working on a PC running Windows 11 can be frustrating, especially when the device powers on normally but the computer cannot see the camera feed or the software refuses to connect.
The problem is not always caused by Windows itself. The connection method matters because the Mevo Plus can be used with a computer through supported webcam and streaming workflows, while some features depend on the software you are using.
For Windows, Mevo documents a wireless webcam workflow that requires the camera and PC to be on the same network. Mevo also supports wired webcam connections for Mevo Plus.
This guide walks through the most useful things to check when your Mevo Plus camera is not working on Windows 11, including network connection, webcam mode, Windows camera permissions, USB connections, firewall interference, firmware, OBS, and other software.
Why Is My Mevo Plus Not Working on Windows 11?
Several different problems can produce the same symptom.
Your Mevo Plus may:
- Not appear on your Windows 11 PC
- Connect but show a black camera feed
- Appear as a camera but produce no video
- Work in the Mevo app but not in OBS
- Work wirelessly but not through USB
- Connect to Wi-Fi but not appear in the webcam software
- Show a placeholder image instead of the live feed
- Disconnect repeatedly
- Stop working after a Windows or firmware update
The first thing to determine is how you are trying to connect the Mevo Plus.
If you are using the Mevo Wireless Webcam application, the camera and PC need to be on the same network. If you are using wired webcam mode, the camera needs to be connected to the computer through USB and placed into the appropriate webcam mode.
1. Restart the Mevo Plus and Windows 11 PC
Start with a complete restart of both devices.
Turn off the Mevo Plus and restart your Windows 11 PC.
After Windows has loaded:
- Turn on the Mevo Plus.
- Wait for the camera to finish starting.
- Connect the camera using your normal connection method.
- Open the software you are trying to use.
- Check whether the Mevo Plus appears as a camera source.
If the Mevo Plus has become completely unresponsive, Mevo provides a hard reboot procedure. Press and hold the top button for 30 seconds, even if the camera appears to power off before the 30 seconds have elapsed, then power it back on. Mevo says this does not erase saved settings or act as a factory reset.
2. Make Sure the Mevo Plus and PC Are on the Same Network
This is one of the most important checks when using the wireless webcam method.
Your Mevo Plus and Windows 11 computer should be connected to the same network.
Check the Wi-Fi connection on the PC and confirm that the Mevo is connected to the network you expect.
If the PC is connected to one network while the Mevo is connected to another, the wireless webcam software may not discover the camera.
Also check whether your PC is using:
- Ethernet while the Mevo uses Wi-Fi
- A different Wi-Fi network
- A guest network
- A VPN
- A network with client isolation enabled
A PC connected by Ethernet can communicate with a Wi-Fi camera when the network is configured correctly, but guest-network isolation or other router restrictions can prevent devices from seeing one another.
3. Check the Mevo Webcam App
If you are using the wireless webcam method, open the Mevo Webcam application on Windows.
Mevo explains that after installing the wireless webcam software, you select the camera from the Mevo Webcam tray application. If the camera is not listed, Mevo recommends checking that the camera is powered on, connected to the same network as the computer, and restarting the Mevo Wireless Webcam application if necessary.
Look in the Windows system tray for the Mevo Webcam application.
If the Mevo Plus is not listed:
- Confirm that the camera is powered on.
- Confirm that both devices are on the same network.
- Restart the Mevo Webcam application.
- Restart the camera.
- Check the firewall settings in Windows.
4. Check Whether the Mevo Shows a Placeholder Instead of Video
There is a specific situation that can make the Mevo appear to be working while showing no live camera feed.
Mevo explains that if you select Mevo Camera as the video source but have not selected a connected Mevo camera from the Mevo Webcam application, the computer can display a default placeholder image instead of the live video.
To fix it:
- Find the Mevo Webcam icon in the Windows system tray.
- Open the Mevo camera selection menu.
- Select your connected Mevo Plus.
- Return to the application using the camera.
- Check the video feed again.
5. Try Wired Webcam Mode
If wireless connection is not working, test a wired connection.
Mevo supports USB Video Class (UVC) webcam functionality. In wired webcam mode, the camera connects to the computer through USB and is presented to the computer as a standard webcam.
Before testing:
- Make sure the Mevo Plus is fully powered on.
- Use a suitable USB data cable.
- Connect the camera directly to the PC rather than through a hub.
- Enable the appropriate wired webcam mode.
- Open your camera software and check for the Mevo camera.
A USB cable that only supplies power may not provide the data connection required for webcam use.
If the Mevo Plus works through USB but not wirelessly, that points toward a network or wireless webcam configuration problem rather than a camera hardware failure.
6. Check Windows 11 Camera Permissions
Windows 11 can prevent applications from accessing a camera even when the device itself is working.
Open:
Settings → Privacy & security → Camera
Make sure camera access is enabled.
Then check that:
- Camera access is turned on.
- Let apps access your camera is enabled where applicable.
- Let desktop apps access your camera is enabled.
After changing the permissions, completely close the application and open it again.
7. Check the Camera Source in Your Software
Your Mevo Plus may be working correctly while your application is simply using the wrong video source.
Open the application’s camera or video settings and look for the available devices.
For OBS, Mevo’s documentation says to add a Video Capture Device and select the Mevo from the device list when using the wired webcam method.
If you have multiple webcams, temporarily disconnect the others and test the Mevo Plus by itself.
8. Close Other Programs Using the Camera
Windows applications can sometimes compete for access to the same camera.
Close programs such as:
- OBS Studio
- Streamlabs
- Microsoft Teams
- Zoom
- Discord
- Browser tabs using a camera
- Other camera applications
Then reopen the program you actually want to use.
If the camera starts working after closing another application, you have likely found a software conflict.
9. Check Windows Firewall
A firewall can interfere with network-based camera connections.
If the Mevo Plus is powered on and connected to the same network as your PC but does not appear in the Mevo Webcam application, check whether Windows Firewall is blocking the Mevo software.
Open:
Windows Security → Firewall & network protection → Allow an app through firewall
Look for the relevant Mevo application and make sure it is allowed on the network profile you are using.
Do not disable Windows Firewall permanently just to test the camera. Allowing the required application is a better approach.
Mevo’s OBS troubleshooting documentation also recommends checking for firewalls blocking the stream when the video window is black.
10. Temporarily Disconnect a VPN
If you use a VPN on your Windows 11 PC, temporarily disconnect it and test the Mevo Plus again.
A VPN can change how network traffic is routed and may interfere with local-device discovery.
If disconnecting the VPN fixes the problem, check its local-network or LAN-access settings rather than leaving the VPN permanently disabled.
11. Update the Mevo App and Firmware
An outdated camera firmware version or application can cause compatibility problems.
Mevo recommends keeping the camera app and firmware up to date when troubleshooting webcam problems.
Use the Mevo app on your supported mobile device to check the camera’s firmware information.
If an update is available, install it according to Mevo’s instructions.
Do not install firmware files from unofficial websites.
12. Test the Mevo Plus in Another Windows Camera Application
Testing another application can help identify where the problem is occurring.
If you are trying to use the Mevo Plus in OBS, test whether another compatible camera application can see the device.
The results can help narrow things down:
Works everywhere: The original application is likely the problem.
Works in Windows but not OBS: Check the OBS video source and permissions.
Does not appear anywhere: Investigate the connection, webcam mode, network, USB connection, or camera itself.
Works over USB but not Wi-Fi: Focus on the wireless network and Mevo Webcam software.
13. Troubleshoot Mevo Plus With OBS
If your problem is specifically with OBS Studio, start by determining which connection method you are using.
Mevo documents several ways to send video to OBS, including wired webcam, RTMP, and SRT. Mevo also notes that Mevo Plus does not support NDI, so NDI instructions intended for other Mevo models should not be applied to the Mevo Plus.
For wired webcam mode:
- Connect the Mevo Plus to the PC through USB.
- Enable wired webcam mode.
- Open OBS.
- Add a Video Capture Device source.
- Select the Mevo camera.
- Check the preview.
If you are trying to use NDI with a Mevo Plus, switch to a supported method such as webcam, RTMP, or SRT instead.
14. Check the USB Connection
If the Mevo Plus works wirelessly but fails through USB, investigate the physical connection.
Try:
- A different USB cable
- Another USB port
- A direct connection to the PC
- A different PC if available
Avoid USB hubs during troubleshooting.
The cable needs to support data transfer. A cable that only charges the camera will not provide the required webcam connection.
15. Check Windows Device Manager
When using a wired webcam connection, open Device Manager and look for the camera under the available camera or imaging-related device categories.
You can also check for devices with warning symbols.
If Windows detects a camera device but reports an error, restart the PC and reconnect the Mevo.
Avoid downloading random third-party drivers. Mevo’s UVC webcam mode is designed to use standard USB webcam functionality rather than requiring a conventional proprietary webcam driver installation.
16. Restart the Mevo Plus If It Is Completely Unresponsive
If the camera itself is behaving strangely, perform the official hard reboot before trying more complicated recovery procedures.
For Mevo Plus, Mevo says to press and hold the top button for 30 seconds, then power the camera back on. The hard reboot does not erase saved settings.
After restarting:
- Wait for the camera to finish booting.
- Reconnect it to your network or PC.
- Open the Mevo software.
- Check the camera selection.
- Test the feed again.
17. Do Not Start With Firmware Recovery
Firmware recovery exists for the Mevo Plus, but it should not be the first thing you try because your PC cannot see the camera.
Mevo describes firmware recovery as a last-resort troubleshooting procedure for situations such as the camera not powering on properly or failing to enter hotspot mode. Mevo recommends opening a support ticket before attempting the recovery process.
If your Mevo Plus powers on normally and the only problem is that Windows 11 cannot access the camera feed, work through the network, webcam, permissions, firewall, and software checks first.
18. Check Whether the Problem Is Windows 11 or the Mevo Plus
A useful isolation test is to change only one part of the setup.
Mevo Plus + another PC works: The Windows 11 PC or its software configuration is likely responsible.
Another camera works on the Windows 11 PC: The problem is more likely specific to the Mevo connection or configuration.
Mevo Plus works with another connection method: The camera is probably functional, and the original connection method needs troubleshooting.
Mevo Plus fails everywhere: Investigate the camera, firmware, or hardware.
This approach is much more useful than repeatedly reinstalling software without knowing which part of the setup is failing.

Mevo Plus Camera Shows a Black Screen on PC
A black video preview does not necessarily mean the camera is broken.
If you are using the wireless webcam application, make sure an actual Mevo camera has been selected from the application’s system tray. Mevo says that selecting the generic Mevo Camera source without selecting a connected Mevo can result in a placeholder rather than the live feed.
If you are using OBS, check the selected source and make sure another application is not already using the camera.
If you are using a network connection, check the firewall and local-network configuration.
Mevo Plus Not Detected by Windows 11
If Windows does not detect the Mevo Plus at all, first determine whether you are using USB or wireless connection.
For USB:
- Try another data-capable cable.
- Try another USB port.
- Connect directly to the PC.
- Enable wired webcam mode.
- Restart Windows.
- Check Device Manager.
For wireless:
- Confirm the camera and PC are on the same network.
- Open the Mevo Webcam application.
- Select the camera from the system tray.
- Check Windows Firewall.
- Temporarily disconnect a VPN.
- Restart the Mevo Webcam application.
Mevo Plus Works on Phone but Not on PC
If your Mevo Plus works normally through the mobile app but not on Windows 11, that is useful information.
It suggests that the camera itself is at least functioning sufficiently for the mobile workflow.
Focus on the PC side:
- Network configuration
- Mevo Webcam software
- Windows camera permissions
- Windows Firewall
- USB connection
- Camera source selection
- OBS or other software configuration
You do not need to assume that the camera hardware has failed simply because the PC cannot access it.
Does Mevo Plus Work as a Webcam on Windows 11?
Yes. Mevo documents webcam functionality for Mevo Plus, including a wireless webcam workflow for Windows and wired USB webcam functionality. The current Mevo documentation lists Windows 10 x64 as the stated requirement for its wireless webcam software, so Windows 11 compatibility should be checked against the current software and support documentation for your exact setup.
Can I Connect Mevo Plus Directly to a PC With HDMI?
No. Mevo says the Mevo Plus does not provide a traditional HDMI or SDI video output. For computer video workflows, use supported methods such as USB webcam, RTMP, or SRT instead.
This is important because buying an HDMI adapter will not solve a Mevo Plus connection problem.
Why Is Mevo Plus Not Showing in OBS?
If Mevo Plus is not showing in OBS, check the connection method first.
For USB webcam mode, enable wired webcam mode and add a Video Capture Device in OBS, then select the Mevo camera. If you are using network streaming, use a supported method such as SRT or RTMP.
Do not select NDI for a Mevo Plus because Mevo’s current documentation states that the Mevo Plus does not support NDI.
When Should You Contact Mevo Support?
Contact Mevo support if you have:
- Confirmed the camera powers on normally
- Tested the network or USB connection
- Confirmed Windows permissions
- Checked firewall settings
- Updated the relevant software and firmware
- Tested another compatible application
- Tried another computer or connection method
- Performed the official hard reboot
- Still cannot get the camera to work
Avoid jumping into firmware recovery unless Mevo support or the official documentation indicates that it is appropriate for your specific problem. Mevo explicitly recommends support confirmation before using the Mevo Plus firmware recovery procedure.

No. Mevo’s current documentation says Mevo Plus does not support NDI. Use supported alternatives such as webcam, RTMP, or SRT for computer workflows.
Can I use Mevo Plus with OBS on Windows?
Yes. Mevo documents connecting Mevo cameras to OBS through supported methods such as wired webcam, RTMP, and SRT. Mevo Plus should not be configured as an NDI source.
What should I do if my Mevo Plus is frozen?
Perform the official hard reboot by pressing and holding the top button for 30 seconds, then power the camera back on. This does not perform a factory reset.
Should I use Mevo firmware recovery if Windows cannot detect my camera?
Not as a first step. Mevo describes firmware recovery as a last-resort procedure for specific problems and recommends contacting support before attempting it.
Why does Mevo Camera appear but show no live video?
With the wireless webcam workflow, the generic Mevo Camera source can display a placeholder until you select the actual connected Mevo camera from the Mevo Webcam application’s system tray.
A Mevo Plus radar camera not working on a Windows 11 PC does not automatically mean the camera is defective. Start by identifying whether you are using wireless webcam, wired USB webcam, or another supported streaming method.
For wireless connections, focus first on network discovery, the Mevo Webcam application, firewall settings, and selecting the actual Mevo Plus. For USB connections, focus on webcam mode, the USB cable, USB port, and Windows camera access.
If you use OBS, remember that Mevo Plus does not support NDI, so use a supported connection such as webcam, RTMP, or SRT. If the camera itself becomes unresponsive, try the official 30-second hard reboot before considering more advanced recovery procedures.
The key is to isolate the connection method first. Once you know whether the problem is network discovery, USB detection, Windows permissions, application configuration, or the camera itself, troubleshooting becomes much more straightforward.
