LensLink Camera vs TetherCam

LensLink Camera turns your iPhone or iPad into a camera for OBS Studio. Mount the phone, open the app, and it appears in OBS as a video source over Wi-Fi or a USB cable — with the picture quality the phone's camera is actually capable of. Picture first Up to 4K at 60 fps, HEVC or H.264, with 120 and 240 fps available where the camera has them 10-bit HDR (HLG) and Apple Log on supported devices Balanced or Maximum quality: Maximum finds the most your connection can carry Every lens, with the Camera app's lens buttons Controls that stay out of the way Tap to focus, hold to lock focus and exposure, drag for brightness, pinch to zoom One tray for exposure, shutter, white balance and focus, with faces-first autofocus The same controls in a browser panel on your computer, and in OBS itself Remember camera settings: a shot dialed in once stays dialed-in Built for production Remote start: OBS starts the camera while the app sits idle Tally light: a colored border says when you're on air Pause with a held picture instead of a frozen frame Keeps streaming beside other apps on iPads that support it Automatic lip-sync: the plugin measures latency and aligns your real microphone Virtual green screen, right on the phone Mirror your whole screen with app audio Siri and Shortcuts Private by design Nothing is recorded on the phone, and nothing leaves your local network. No account, no sign-in, no analytics. Requires OBS Studio and the free, open-source LensLink plugin for Mac, Windows or Linux: https://lenslink.cam

Your iPhone, instead of a webcam. TWO APPS, ONE CABLE TetherCam is two free apps. TetherCam for Mac is downloaded from tethercam.app; TetherCam for iPhone is this one. Install both, connect the phone to the Mac with the USB cable you already own, and the iPhone shows up as the camera "TetherCam" on the Mac, in the same camera picker as the built-in one. It works in every Mac app that lists system cameras: Zoom, Microsoft Teams, Google Meet, FaceTime, QuickTime Player, Safari, Chrome and the rest. Zoom and Microsoft Teams were verified on 10 September 2026. Nothing travels over Wi-Fi, nothing passes through a server, nothing is uploaded anywhere. There is no account, no pairing code and no discovery step. The cable is the whole path, which is why the picture stays stable in a crowded room where wireless cameras start to stutter. WHAT YOU NEED An iPhone with iOS 17 or newer, a Mac with macOS 14 or newer, and the USB cable that came with the phone. The free TetherCam Mac app asks once for approval of its camera extension in System Settings; after that the camera is simply there. THE HONEST LIMITS The Mac app carries the picture only. A Mac camera extension has no audio stream, so the sound stays with the Mac's own microphone. Audio over the cable exists, but only on the OBS path below. This iPhone app stays open in the foreground while it sends. The phone serves one receiver at a time. The Mac app and the OBS plugin are not used together; whichever connects second is told that the line is busy. ON THE PHONE Live preview from the moment you open the app, before anything is connected. A camera and lens picker for the wide, ultra wide and telephoto lenses or the front camera, switching the stream immediately. Automatic rotation that follows the horizon rather than the interface. Turn the phone and the picture stays level, because the orientation is resolved on the capture side. There is a manual angle override when you want to decide yourself. Hardware HEVC encoding, which keeps the phone cool and the latency low. A diagnostics panel that shows what is actually happening: listener state, connection, frames per second, bitrate and the measured levelling residual. FOR STREAMING AND RECORDING: OBS STUDIO The TetherCam plugin for OBS Studio is the pro path, also free and also at tethercam.app. It adds a source called TetherCam directly in OBS, finds the phone through the same cable, and it is the only path that brings the microphone of the phone across as well. PRIVACY No account, no analytics, no advertising, no purchases. The camera picture goes to your own Mac and nowhere else. Nothing is collected. TetherCam for iPhone is free and open source under the MIT licence at github.com/Kanevry/tethercam.
