-
Connect both devices to the same Wi-Fi
Make sure your laptop and phone are connected to the same Wi-Fi network. Camcastar uses a direct peer-to-peer connection and both devices must be on the same network for it to work.
Note: If they are on different networks, the QR scan will succeed but the video stream will not connect. -
Open Camcastar on your laptop browser
Go to camcastar.com on your laptop. A QR code appears on screen automatically. No login, no setup, no download needed.
-
Scan the QR code with your phone camera
Open your phone's native camera app (not a QR scanner app, just the regular camera). Point it at the QR code on your laptop screen. Tap the link that appears at the top of your screen.
On iPhone, use the built-in Camera app. On Android, use Google Lens or your default camera app. -
Allow camera and microphone access
Your phone browser will ask for camera and microphone permission. Tap Allow. The live feed from your phone camera will appear on your laptop screen immediately.
If you accidentally denied permission, go to your phone's browser settings and re-enable camera access for camcastar.com. -
Control the camera from your laptop
Use the controls panel on the right side of the dashboard to adjust the camera remotely, all in real time.

Reduce latency with Restart Stream
If you notice lag building up during a long session, click Restart Stream in the bottom left of the video panel. This resets the stream buffer and brings the feed back to real-time.
Tips for Best Performance
-
Use 5 GHz Wi-Fi
5 GHz networks have lower interference and higher bandwidth than 2.4 GHz. If your router supports it, connect both devices to the 5 GHz band for the lowest latency and best video quality.
-
Keep the phone screen on
Camcastar uses a wake lock to prevent the screen from sleeping during streaming. If the screen turns off anyway, the stream may pause. Keep your phone plugged in for long sessions.
-
Use Chrome or Safari for best compatibility
Camcastar works in all modern browsers. Chrome on Android and Safari on iPhone give the best camera quality and lowest latency.
