Logitech C920S HD Pro Webcam with Privacy Shutter - Widescreen Video Calling and Recording 1080p Streaming Camera Desktop

If you suddenly find yourself at home and needing a camera for all those Zoom, WebEx, Google Hangout meetings you find yourself on, check out the Logitech C920S Pro Webcam. I was used to using the built in camera's on my Apple Products, but decided to branch out and try this camera, because the quality was really good from what others were saying. Over the past few weeks, I have used it for Skype meetings, Google Hangouts and Zoom meetings and each time the camera adjusts nicely to the changing light conditions. The auto focus feature is nice, and it locks on to the facial features while keeping some things in the background also in focus. The 1080p feature delivers a sharp "true HD" picture. If you want a soft focus in your background, you will probably need to jump to a more expensive camera that can be mounted on a tripod. If the goal is to see people, and have a good web meeting experience, the Logitech C920S HD Pro is a great solution for a relatively modest entry price. Read more

I bought this to use as a webcam on my MacBook Pro and it's been really great so far. Everyone I call comments on the excellent picture quality (much better than the standard camera in the MacBook itself), and it really was 'plug and play' - once plugged in you just had to go into the various system/FaceTime settings to select it as the chosen camera. It has a neat little adjustable bracket assembly which allows you to fix it securely onto the top of your laptop or monitor - whatever their thickness - and allows you to adjust the angle so it sits just right too. The lens cover is a nice touch, for that added security that no one can remotely spy on you! I did try to use the integrated microphones but had some complaints of echo, so I think the MacBook struggles to do proper echo cancellation if it's not using its own mic and speakers together. Other than that no complaints! Read more

If you want a decent webcam for video chat, skype then this is an excellent choice. I often dock my laptop and still need to have a webcam for work meetings. The video quality is decent for 1080p. The lens is glass not plastic so I feel it is a mid range web cam. The mic and speakers are stereo so that is much better than my laptop. The installation was quick and easy. Finally it has a privacy cover that you can block the video when needed. The autofocus does a pretty good job at keeping me in focus when I move. Read more

I bought this because it's the popular choice for YouTube streaming. I'm am making VR mixed reality videos with Oculus Rift. First off, this does NOT do 720p @ 60fps. You have to go down to 640x480 to get 60fps. I did research on equipment needed and chose this as it was popular. What i never read, until AFTER i started playing with it, is logitech disabled 60fps in the firmware a few years ago. Older models used to do 60fps at 720p, but not the newer manufactured models. That being said, it is still a nice webcam and does do the job at 720 and 1080. I just need more clarity in my videos so I'm going a different route. If you're just using it to chat or do simple YouTube videos, this is a great webcam. It does have a Chromakey function in its software that works pretty well. It does green and blue only. Doesn't let you adjust amount of keying though. With my large 10x20 screen, it keyed all of it out easily, wrinkles and all. Color is good. Brightness is good. Auto focus works, but you have to wave something in front of it to get it to refocus. Read more

LINUX Works on Linux using the UVC driver. I must say, I really like how they're now engineering the webcam devices now adays! A universal driver, with the camera electronics providing several stream devices. DIFFERENCES C922 vs C920 I'm guessing the differences between the C922 and C920, the C922 just provides a faster processor (CPU) for faster frame rates (fps) while lacking a privacy cover. Thinking they're assuming the blue LED light upon camera activation is adequate. Both provide glass lenses, while the C922 also includes a small stand. Likely, instead of other people looking down upon you, they're looking up at you. LINUX INSTALLATION Linux Kernel linux > drivers > Multimedia (media) > USB Video Class (UVC) If the module/driver hasn't already automagically loaded, then load the driver # modprobe uvcvideo Ensure you're using the correct audio record device, mine is hw:0,0 using an additional PCI-E Asus Xonar ST, although you may prefer the webcam's built-in. $ arecord --list-devices Ensure you're using the correct video device, mine is /dev/video2, as I have a Hauppauge TV/video capture card. $ v4l2-ctl --list-devices Capture some audio/video: $ ffmpeg -f v4l2 -video_size 640x480 -i /dev/video0 -f alsa -i hw:0,0 -c:v libx264 -preset ultrafast -c:a aac -crf 0 webcam.mp4 Thinking on the whim in conjunction what TV ATSC uses, MPEG TS or PS, are probably the best defacto stream recording methods, easily played, edited or archived, $ ffmpeg -f v4l2 -i /dev/video2 -f alsa -i hw:0,0 webcam.ts NVIDIA NvENC H/W ACCELERATION When trying the maximum resolutions 1080p (1920x1080) or 720p (1280x720), all I get is broken audio/video sync, "Audio/Video desynchronisation detected!" FFMpeg error. See below TODO items. The Windows Logitech Camera Capture software averts the desynchronization by likely using Nvidia's NvEncoder, as I have a Nvidia Geforce 670 video card. Took me awhile, but I now have 1080p/720p stutter free on my Linux box, substitute "-video_size 1920x1080": $ ffmpeg -f v4l2 -input_format "mjpeg" -video_size 1080x720 -i /dev/video2 -f alsa -i hw:0,0 -pix_fmt yuv420p -acodec aac -c:v h264_nvenc -pixel_format yuv444p -y /tmp/output.mp4 First, we specify the "mjpeg" instead of the "yuyv422" stream provided by the camera, as yuyv422 is rawvideo and still to heavy on resources here. My video size, then video device. Next I specify my alsa device for sound recording, rather than the cheap on-camera microphone. The key to using Nvidia's nvenc on linux or using FFMpeg, the placement of "-pix_fmt yuv420p" for converting the yuyv422/yuyvj422 input stream to a compatible Nvidia nvenc format, after the input streams and before specifying the output codecs! Then the output alsa and h264 codecs, along with the output filename. (FFMPeg's NvEnc page seems to specify incompatbile or out-dated flags/options.) TIP: The uncompressed raw video is provided by a yuyv422 stream device from the camera, specified by v4l-ctl. (eg. $ v4l2-ctl --list-formats --device /dev/video2) When pulling the yuyv422 raw video, can push only rawvideo into a *.yuv container. Specifying *.avi container tends to transcode audio/video. This interface is likely used for photos or snapshots by Logitech's Camera Capture. TIP: Instead of specifying non-indexed randomized /dev/video? numbers as Linux kernel drivers currently provide no indexing unlike additional sound cards, can access the specific camera by using, "/dev/v4l/by-id/usb-046d_HD_Pro_Webcam_C920_89A6F41F-video-index2" a symlink to /dev/video2 device. TIP: Windows FFMpeg options using DirectShow, within shell or Cygwin: List Devices $ ffmpeg -list_devices true -f dshow -i dummy List a Device's Resolutions $ ffmpeg -f dshow -list_options true -i video="HD Pro Webcam C920" Sample Recording $ ffmpeg -f dshow -i video="HD Pro Webcam C920":audio="Microphone (ASUS Xonar Essence STX Audio Device)" out.mp4 TODO: Can record microphone and video camera activates, but FFMpeg created file doesn't seem to contain a video, only audio? NOTE: Oddly, the gspca_vc032x module will recognize the Logitech 920s (046d:0892) device string, so if experiencing collisions or problems, try blacklisting or removing the gspca_vc032x driver. TODO: My Logitech's software Camera Capture created video containers/files contain four additional audio streams rather than just two audio streams for stereo or one audio stream for mono. (FFprobe reports one VideoHandler stream with four SoundHandler containing three AAC streams.) Possibly just capturing all available microphone stream devices? Three are identical kbps with one lacking a few kbps, and upon further analyzing, three contain direct feed from my secondary sound card microphone by testing by directly tapping on the microphone. I could be wrong, and the webcam mics could be extremely sensitive sounding as if I'm tapping on it instead of my secondary mic. This is something that hopefully can be fixed, else it should be considered a bug. Read more
