Quick Camera
Quick Camera is a macOS utility for viewing the live output of connected USB cameras in a resizable desktop window.
What is Quick Camera?
Quick Camera is a native macOS camera utility that helps you display the live feed from a connected USB camera on your desktop. It is designed for people who need a simple camera viewer rather than a full recording or conferencing app, including presenters, teachers, and users working with document cameras, microscopes, or other external video devices. The app focuses on showing a camera feed clearly in its own window, with options that make the image easier to position and present on screen. It supports mirroring in multiple directions, image rotation, flexible window resizing, and keeping the camera window in the foreground when needed. On Mac, this makes it useful for demos, classroom projection, showing hardware to an audience, or monitoring a camera feed while using other apps.
Key features
- View live output from connected USB cameras
- Mirror the image vertically, horizontally, or in reversed orientations
- Rotate the camera feed for different mounting positions
- Resize the viewing window to fit your workspace or presentation
- Keep the camera window in the foreground while using other apps

Safety overview
Status: Mostly safe
Quick Camera's camera access is consistent with its purpose as a live camera viewer. Because it displays video from connected cameras, you should expect macOS to request Camera permission before use. Review that permission in Privacy & Security if you no longer use the app, and confirm the installed app is the Quick Camera product with bundle ID com.simonguest.QCamera if you want to avoid confusing it with similarly named camera apps from other publishers.
Recommendation: Keep Quick Camera if you use a USB camera for presentations, demos, classroom display, or simple live viewing on your Mac. If you do not use external camera feeds, you can remove it without affecting macOS, though any presentation or viewing workflow built around it will stop working until you reinstall it.
