How to use Phone Camera Mirror: First, open this page on both your phone and computer. On both devices, select the SAME channel letter (A through E) using the buttons at the top. On your PHONE, tap the green "Start" button — this activates your camera and begins broadcasting. You'll see your own camera preview. Use the phone controls to Rotate the view (0° → 90° → 180° → 270°), toggle the Torch/flashlight (if supported), or adjust Zoom using the slider (hardware zoom on supported devices, CSS zoom fallback for Firefox). On your COMPUTER, click the green "Connect" button. The PC will automatically find your phone via Firebase signaling and establish a direct WebRTC peer-to-peer connection. The live camera feed will appear on your PC screen. On the PC, you can Rotate the view, or click "Detach" to pop out the camera feed into a movable, resizable floating window that stays on top of other apps. Floating window supports drag, resize, minimize, and maximize. Click "Attach" to return it. Click "Disconnect" on PC or "Stop" on phone to end the stream. Both devices must stay on the same Wi-Fi network for optimal performance. No account, no server storage — your video stays private and direct.
