01 / Signal path
Direct by design.
NoSub Cam sends the image to the receiver you choose. The publisher does not operate a video relay, user account system, or recording service.
Scan once. Remember the link.
Show the pairing QR in NoSub Studio and scan it on iPhone. Both apps remember the pairing; reset it whenever you choose.
Use NoSub Camera
Install and approve the desktop camera component, enable output, then select NoSub Camera in your video app. OBS is optional.
02 / Mobile camera
Focused before the first frame.
Scan the desktop pairing QR, allow Camera and Local Network access, and start streaming. Connection, status, and the streaming action stay together on one screen.
One screen, one job.
The phone handles capture. NoSub Studio handles the camera controls. Flat anthracite surfaces, compact corners, and warm orange controls keep the same visual language across both devices.

03 / Studio controls
The useful controls stay visible.
Camera settings and presets on the left. Preview in the center. Pairing and webcam output on the right. Settings apply as you change them.
04 / Capabilities
Local tools, not a service.
The product is intentionally small: two companion apps that connect devices you already own.
Wi-Fi or Direct USB
Use a trusted local Wi-Fi network or connect through Apple's local USB device service.
Camera controls and presets
Select front or rear, resolution, and frame rate from the desktop. Adjust supported exposure, focus, white balance, and zoom, and save presets for next time.
Native webcam output
Select NoSub Camera in your video app for 1080p30 output, without OBS. Approve the extension on Mac or install the camera component on Windows.
No account or tracking
No developer-operated backend, advertising network, analytics SDK, or subscription system.
Security note
Wi-Fi mode uses unencrypted HTTP on your local network. Use a private network you trust, protect pairing details, and never expose the receiver port to the public internet.
Start local
One camera. Two companion apps.
Install NoSub Cam on iPhone and NoSub Studio on the receiving computer.
