Can you detect OBS or a virtual camera in an interview?

OBS Studio is a popular free tool for streaming and recording, and its Virtual Camera is used by plenty of honest people. It also means the video in your interview may not come straight from a webcam. This guide explains what a virtual camera is, what you can and cannot see, and what to do if a candidate is using one.

What a virtual camera is

A virtual camera is software that other apps can pick like a webcam. The OBS guide describes its Virtual Camera as a way to share an OBS scene with "any applications that can make use of a webcam", and names Zoom, Skype and Discord. ManyCam calls itself "an easy-to-use virtual camera and live streaming software". OBS, ManyCam and similar tools are ordinary products with ordinary uses: better lighting, a tidy background, slides or a second camera.

Why it matters in an interview

Whatever the software shows can go into the call. That can be the candidate's webcam with a cleaner background. It can also be a recording or another face. The FBI warned in June 2022 of complaints about deepfakes and stolen identities used to apply for remote jobs. The README of one open-source face-swap project, Deep-Live-Cam, read on November 1, 2026, tells webcam users to stream with "a screen capture tool like OBS".

So camera software is not a problem in itself. A swapped face or a recording is often sent into a call this way, which is why it is worth knowing about. More on this is in the guide to deepfake candidate detection.

What an interviewer can see

In the call, you see a picture. You do not see which device made it. A clean picture does not prove a direct camera, and a glitchy one does not prove camera software. Honest webcams freeze and blur too.

You can ask for simple actions on camera. BrightHire's guide suggests turning the head to profile, waving a hand across the face or changing the lighting. These can help with a live face swap, but they tell you nothing about a harmless background tool, and they are awkward to ask of every candidate. For the wider method, see the guide to the signs worth noticing.

How virtual camera detection works in hiring tools

Tools that check this look at the route, not the picture. Public examples, each in the vendor's own words:

• Talview. Its documentation says its Live Interview screen shows "Virtual camera detected on candidate's device." and names examples such as OBS Virtual Camera and ManyCam. See Verified Call vs Talview.
• InterviewGuard. Its report lists the video source as "Physical webcam or virtual camera software". See Verified Call vs InterviewGuard.
• Verified Call. It checks whether the video comes from a direct camera or from camera software, before the call and during it.

A camera's name alone is weak evidence, because the software that creates a camera sets its name. When you compare cheating detection tools, ask each vendor how it was tested and how often a normal webcam was flagged.

What to do when camera software is found

1. Ask a neutral question. "Are you using camera software today? Could you switch to your built-in camera for this call?"
2. Allow for honest reasons. Backgrounds, lighting and second cameras are all common, and the answer is often simple.
3. Note what happened. Write down what was found and what the candidate said.
4. Decide with the rest of the evidence. A finding is a reason to ask, not a verdict. Use the same step for every candidate.

Verified Call’s test results

Verified Call tells a direct camera from camera software on the candidate's own computer. If video comes through software, the host sees Needs a look, with a short note next to the person.

29 of 29

tries each, 9 kinds of camera software and 7 direct cameras read right (September 30, 2026)

20 of 20

live calls read right: 10 direct cameras and 10 face swaps sent through camera software (October 2, 2026)

The 29 tries give at least 90.2% for each one, at 95% confidence, in our own testing. An earlier run misread some direct cameras. We fixed it and tested again, and both results are on the Research page. For sourced numbers across the market, see the interview integrity statistics.
