Question: Is it Widows 8 - 64 bit compatible?
Document: This webcam has superior hardware for its price and is a great way to Skype in 1080p.However, the Logitech software is atrocious if you want to take still photos or record video -- over a year and a half after it's release they have still not made it compatible with 64-bit Windows systems. Buyer beware!
Purchased this item as an upgrade to my Microsoft LiveCam webcam, because the Microsoft product that I purchased a year ago would not work on my laptop after I upgraded to running 64 bit version of Windows 8 (could not find reliable drivers) Received the C920 right on time (you've got to love amazon shipping), plugged it in, and it work perfectly, just as expected.
I've used several web cams with very negative results. But, when I purchased the Logitech HD Pro Webcam C920 my searching ended for a great device. It works great connected to a PC or Laptop with Windows 8 or 7 operating system (64 bit or 32 bit). Just follow the software download instructions and you'll have one great experience. I must inform you that all of my systems have 8GB of RAM and Intel quad- processors.
It works great on my Windows Desktop P C using Windows 7 64 bit. It streams well on U Stream
But - and this has been a problem with other Logitech webcams as well - the drivers don't always play well with Windows (7, 64 bit in this case). Blue screens abound! Come on, Logitech, Windows is a pretty important market, don't you agree?
Webcam arrived quickly as usual. The video quality of this webcam is excellent. The people we Skype with noticed the difference right away. Installation on Win7/64 bit was hassle-free and we were up and running quickly. Haven't had any issue with the webcam so far.
I got this webcam to talk to my daughter in Europe via Skype. The quality is unsurpassed. The camera worked immediately in Windows 7 (64 bit) and Ubuntu Linux 12.04.Easy to use, excellent quality, decent price. Would definitely recommend.
Purchased the camera to operate on a new computer, plenty of ram and processor speed (Win 7, 64 bit,12GB 3.4Gz...). No software included included in package, instead you must download from Logitech. Well, that should be fine except the software is buggy, upon downloading it will not install.
This may be a good product if you have a top of the line computer and studio lighting. But my experience using normal office lighting and a dell computer purchased 6 months ago was subpar. HD was hardly any different that 480p. I was running 64 bit windows 7 with 4 GB of ram.
We purchased the Logitech HD Pro C920 for our Meeting Room for teleconferencing. We downloaded the software from the Logitech site for WIndows 7 64-bit. We had some bugs with the webcam freezing. We uninstalled the software and re-installed. The camera has been working better so far.It is clear with good visuals. The ability to zoom and pan is a great convenience.
Answer: Yes this Webcam Is Compatible with Windows 8 64 bit! Its a great Webcam, the audio is superb and the quality of the 1080p Resolution and great for all types of recording, whether its a Skype or Google Hangout or just a random video for you to save to your local drive ( Your computer) I recommend downloading the free software for this webcam that allows you to control it, You can find it on the logitech website http://www.logitech.com/en-us/support/hd-pro-webcam-c920?section=downloads&bit;=&os;id=23    Hope this helps My friend!
