You can also use the C920 as security cam thanks to the motion-detection mode, which can come in handy if you want to keep an eye on your desk. The software features a number of backgrounds and avatars to add a bit of fun to your videoconferencing. If you use this at a desk, you'll likely need to use it only once, but users on the go might find themselves relying on these framing options more often. The app allows users to zoom in and out with the camera, as well as pan left and right. The company touts support for Mac OS X, Chrome OS and Android, but those operating systems don't offer this program. The C920 is compatible with Logitech's Webcam Software for Windows. However, the C930e had superior noise cancellation, while the C310 didn't do much to dampen background noise. Though I recorded my chat in an open-office setting, there wasn't a ton of ambient noise from nearby co-workers. Recorded with the C920's built-in microphones, the audio in my sample video was loud and clear, but a little flat. A cheaper, 720p camera, the Logitech HD Webcam C310, was grainy in comparison and wasn't as sharp in low light. A photo I took with the 930e made my light red shirt look more like a cherry red. Logitech's business version of this camera, the $98 C930e, offers almost identical performance but has a 90-degree field of view and colors that are more vibrant but less accurate.
