It’s a marvel to think just how far webcams have evolved over the last twenty years. Back in 1991, it all began when geniuses at Cambridge University streamed a 128×128 representation of a coffee pot in glorious grayscale – serious business, no doubt. Today webcams can still be used to monitor coffee, of course, but they more frequently play a role in connecting families, friends, service members and business professionals all across the globe. And thanks to the High-Definition craze, we’re just beginning to see webcams that can do it all in 1080p, well over 125x the resolution of the first CoffeCam and in super glorious 24-bit color.
One of the front-runners in this current generation of 1080p cameras is Logitech C910 HD Pro Webcam, an impressive piece of kit that pushes the limits of USB 2.0, not to mention the limits of your internet connection. Dual microphones and Carl Zeiss glass optics with auto-focus add flavor to the mix, but is it all worth it? Find out in our in-depth review.

The Logitech C910 HD Pro Webcam marks an important milestone where Logitech has finally cast off the child-like playfulness of their QuickCam heritage with a new industrial design that seems less like a toy and more like a piece of professional equipment. The shiny, round and ecceltric elements of the previous webcam generation have been traded in for a flat, minimalist profile that feels more at home atop modern LCD screens. The camera lens sits straight in the middle, surrounded by a set of blue activity LEDs and dual microphones. It’s this symmetry that truly makes the C910 appear classy.
The mounting hardware has also been improved over Logitech’s older webcams. A more prominent front lip to grasps onto the front of the monitor, while a shorter L-shaped hinge provides a fair amount of tension with its wide, rubber padding. A second hinge just behind the camera itself allows for vertical tilt adjustments independent of the mounting hardware, though horizontal panning is still a lost luxury. Overall, the new mounting hardware does a good job of removing unwanted camera motion, but still lacks a tight grip on thinner laptop displays that a spring-mounted clip would provide.
On a sour note of caution, the cable length of the Logitech C910 has been shortened to just under five feet, down a whole foot from the last generation. This poses a serious issue for some larger desktop arrangements including my own, and affected buyers may need need to invest in a quality powered USB hub to bridge the gap. When I first tried to do so using a simple 12-inch USB extension cable or my desk’s cheap built-in hub, a menacing high-pitched pulsating tone was introduced into the audio stream whenever the camera’s optics were active. My friend in Japan was quick to point out the agitating noise during a Skype call, but thankfully I was able to quickly eliminate the problem by plugging the camera into a different hub. Snapping on some additional ferrite beads may have also worked, but unfortunately I don’t have any lying around to test with.
Software
The Logitech C910 HD Pro Webcam is fully compliant with the USB Video Class (UVC) specifications, allowing it to be used in standard and widescreen aspect ratios on just about any computer without the need for extra drivers. The lighting-adjustment algorithms known as RightLight along with focus and white balance are also built into the camera hardware, able to be manually adjusted or set to auto from within Microsoft’s drivers.
If you do happen to install Logitech’s Windows drivers, however, you’ll be treated to a newer version of Logitech Webcam Software v2.30 that again sheds the quirky look of the older QuickCam generation. The new, more modern interface of LWS is rather bulky, but effectively uses white space to present a simple, uncluttered look. All of the features of the older drivers are present and accounted for, but many have been repositioned more or less intuitively across the software.
Quick Capture and Image Controls
At the forefront of Logitech Webcam Software package is the classic Quick Capture utility, which makes it a breeze to capture photos and videos in a wide array of resolutions both widescreen and 4:3, up to a native 2592×1944 (5MP) native resolution. Photos are captured as JPEGs, and videos as Windows Media WMVs using one of three compression settings.
Image controls will appear to the right of Quick Capture for basic adjustments like face tracking, zoom, panning and focus. These same controls can also appear in a pop-out controller whenever the camera is accessed by a third-party program like Skype, though the audio mute button will be missing. Advanced settings are accessed in a separate oversized window, providing granular controls over the camera’s exposure, color balance and more. The camera image can also be mirrored here, but only horizontally. In the main preferences menu, the twin blue LED indicators can be set to turn on whenever the camera is active, or switched permanently on or off globally.
Also accessible from the main menu is the Webcam Gallery. This serves as a quick way to preview all content captured by the Logitech applications, sorted chronologically in a filmstrip. The main focus here is automation shortcuts; a simple menu makes it easy to quickly import a photo or video into an editing program of your choice, or share content by social media and email. Logitech has heavily advertised MAGIX Video easy and Photo Manager for editing content, but after trying both and seeing how basic they are, I’d advise you to stick with Windows Live Movie Maker and Google Picasa.
Video Surveillance
Still included in the software bundle is Logitech’s Motion Detection program, allowing the recording of any event that exceeds a predetermined motion threshold. Timestamps and basic scheduling are supported, though masking zones with independent sensitivities is still a missing feature. Video resolution is also rather limited at 800×600, but this is probably done to minimize CPU usage.
Perhaps the biggest improvement to the Motion Capture program in LWS 2.3 is that audio is finally able to be recorded as an option. Contrast this to previous versions of QuickCam software, which cited wiretap law for disabling it by design. I am not a lawyer, but do know that wiretap law differs state-by-state, and many times the audio recording of conversations is perfectly legal so long as there isn’t a reasonable expectation of privacy. This was a legitimate concern when I wanted to tape my dormitory inspections as an enlisted Airman, so I’m glad Logitech finally the burden of the law in the hands of its users.
Logitech Video Effects
Entertaining small children is still made easy by Logitech’s video effects, a collection of simple filters and camera distortions, as well as facial accessories and 3D avatars that track your movements. The majority of these have remained the same since the Logitech’s QuickCam Ultra Vision, but they’re still fun to play with and are of generally higher quality than the comparable effects from Microsoft LifeCam Cinema offerings.
To keep things fresh, a new toy has been added to the Video Effects suite in Logitech Webcam Software 2: video masks. Have you ever wanted to substitute a ravenous baby’s eyes and mouth with your own? No? Me neither, but Logitech makes it possible.
A limited selection of pre-built video masks is included with the software, but this is quickly expanded upon by Logitech’s Video Mask Maker. Any image stored on your computer can be turned into a video mask, allowing for multiple sets of eyes and mouths that can be rotated and resized about the picture. It remains to be seen if Internet culture will embrace this as a natural extension of memes or not.
3rd Party Trialware – FastAccess Facial Recognition
Beyond hosting Logitech’s own software, LWS v2.3 serves as a gateway for downloading other webcam-enabled software endorsed by Logitech. One of these advertised programs for download is FastAccess from Simple Vision, a facial recognition utility that automates Windows logins and internet passwords. It can also be configured to lock the computer automatically whenever you walk away. FastAccess is limited to a 15 day trial, however, after which you’re expected to pay $30 for the full version. Don’t waste your money.
First off, this program has some serious bugs to it. FastAccess installs a webcam splitter so that it’s able to constantly monitor for faces, yet still provide webcam access to programs like Skype or Quick Capture. This workaround has some interesting quirks such as reduced picture quality, certain camera resolutions displaying nothing, and others resolutions showing an awkward green border as shown in the screenshot below. Oh, and switching between camera resolutions in Quick Capture while FastAccess is running will cause a blue screen of death about half of the time.
Even ignoring these bugs, I believe there are some fundamental issues with the very concept of face recognition software. Running the camera and facial detection algorithms constantly will take a toll on battery life and CPU usage, roughly 10% on a 3.0GHz Core 2 Duo. Facial detection is also far from secure, easily hacked with a photograph. The article I just linked is now over two years old, and yet so far the only improvement the industry has made in the interim is to check for eye movement. This isn’t good enough.
Let’s say that you video chat with a friend every now and then, only that friend isn’t so friendly. Or perhaps the significant other you Skype with is a bit nosy. It’s absolutely trivial for them to take two consecutive screenshots during the conversation, one with your eyes open and one with them shut, and then save them to their computer for future hacking. Later while you’re away, a laptop can be held to the camera with the photos maximized on-screen, alternating to simulate human blinking. Voila! Access has been granted.
This is not a theory, it’s an easily-verifiable fact. It took me less than five seconds to break into my own computer with a laptop display, while wearing a mask to ensure my own face didn’t thwart my mischief. The bottom line is that if you want to stay secure, you should stick to passwords, thumbprints or two-factor authentication. Logitech should strongly consider pulling FastAccess from their site until the price and vulnerabilities are better identified to customers up front, and Sensible Vision fixes their horrendously buggy software.
