I Built a Wireless Phone Camera Monitor With Remote Controls

You know that thing where you set up your laptop camera, hit record, walk to your spot, do the thing, walk back to check, and realize you were out of frame the whole time?

I did that five times in one session.

My phone was sitting right there. Better camera. I can put it anywhere. But every solution I found wanted me to download an app, install a driver, or pay for HD. For something that should just work.

So I spent a weekend building Camcastar.

What it does
Open camcastar.com on your laptop. A QR code appears. Scan it with your phone. Your phone camera shows up live on your laptop screen.

That's it.

From your laptop you can control everything remotely:

Switch between front and rear camera
Adjust zoom
Toggle the flashlight
Control Resolution and FPS
Start/Stop Recording from laptop
No app. No cables. No account. Free

Who it's for
Anyone who has ever needed a better camera angle without the setup headache. Creators, developers on video calls, people recording tutorials, anyone who wants to see what their phone sees from their laptop screen.

Try it
camcastar.com

Both devices need to be on the same Wi-Fi. Open the laptop page, scan the QR code with your phone camera, allow camera access, and you are live in about 10 seconds.

Would love honest feedback. What works, what doesn't, what you'd want next. Drop a comment or use the feedback form at contact.
