AlterCam is virtual webcam software for Windows. After install, Windows gets a new camera via a kernel-mode driver — not a DirectShow-only filter and not a pyvirtualcam-style wrapper. That is why AlterCam Virtual Camera shows up in the Windows Camera app, Teams, Zoom, Discord, browsers, and other clients that often hide OBS Virtual Camera.

Pick AlterCam as the camera in any app. Whatever you set up — live webcam, screen, video file, overlays, or AI background — is what those apps see.

What you can do

• Broadcast anything: physical webcam, desktop, image, or a pre-recorded video
• AI virtual background without a green screen (Windows 10 x64+)
• 50+ live effects, text/image overlays, picture-in-picture, chroma key
• Split the webcam so Zoom, Teams, and Discord can use it at once — no "webcam busy"
• Record webcam or screen, take snapshots
• Change your voice in real time, with noise suppression and auto-normalize
• GPU acceleration to keep CPU use lower
• Rename the virtual camera if a service filters by device name

Why people switch from ManyCam or OBS

ManyCam alternatives are usually about price, watermarks, and a lighter workflow. OBS Virtual Camera is free but is a DirectShow filter, so it often does not appear in Windows Camera or some Teams/Zoom builds. AlterCam is built for that gap: a real kernel webcam plus effects in one app.
