Virtual device detection

Detect Synthetic Camera And Voice Setups, Only When They Are Active.

Virtual webcams and voice-changing audio routers can inject synthetic video, hide who is really on the call, or route a helper's voice. InterviewWatch flags these tools when they are actually running during the interview, plus any camera or audio device that changes mid-session.

Device context

A virtual device is not always fraud, but it is always context.

A virtual camera used for accessibility or a known recording workflow may be fine. One that appears mid-interview, alongside remote tools or suspicious timing, deserves a look. That is why these are review-level signals with persistence-aware scoring rather than instant fails.

Active use, not mere installation.

The detectors report a virtual camera or audio router only when its driver or engine is running during the interview. A repeat occurrence nudges the score; further occurrences are logged rather than stacked, keeping the signal honest.

OBS Virtual CameraManyCam

Virtual & voice audio

Flags voice-changing engines and audio routers while running.

VoicemodVoiceMeeter

Mid-session changes

Records camera, microphone, or monitor changes during the interview as environment signals for review.

What a clean report can say

No virtual camera was active, no voice router was detected, and the device set stayed stable throughout the session.

What a risky report can say

A virtual camera became active after the interview began, a voice router was running, or devices changed around a suspicious answer sequence.

FAQ

Virtual device questions, answered.

Does it flag virtual cameras that are only installed?
No. The detector reports virtual camera and audio tools only when they are actively in use during the interview, not merely present on the machine, which keeps noise low.
Which virtual device tools does it recognise?
Virtual webcams such as OBS Virtual Camera and ManyCam, and voice-changing audio routers such as Voicemod and VoiceMeeter, among others in an updateable catalog.
Is a virtual camera always a problem?
No. It can be part of a legitimate workflow, so it is a review-level signal. It becomes more serious when it appears after the interview starts or lines up with other integrity signals.
What does a device change during the interview mean?
A camera or audio device swapped mid-session is recorded as an environment signal. On its own it may be harmless, but near a suspicious answer sequence it is worth reviewing.
