Image quality. It’s more than just megapixels.
Seeing the smile on your grandson’s face or the glitter off your daughter’s engagement ring is so much better than a phone call. And a webcam can really make these experiences possible, even when you’re separated by thousands of miles. But getting the right webcam is more than just a matter of finding the one with the most megapixels.
At Logitech, we’re not just trying to dazzle you with more megapixels. Megapixels are only part of the picture. Image quality—especially when it comes to making a video call—depends on at least five things: the webcam lens and sensor, your computer, your Internet connection, and the video-calling program.
The truth about megapixels
A higher-megapixel sensor doesn’t equal high-quality images on its own, so it’s important not to just look at megapixels and forget about the other aspects of the camera.
Higher-megapixel sensors, however, can give you more fine detail. Pick one of our webcams with a true two-megapixel sensor and you’ll enjoy sharper, more detailed photos.
The right lens
The lens is what captures the light that gets turned into the image by the sensor. If your lens isn’t good, it doesn’t matter how many megapixels you’ve got. A bad lens is going to give you a bad image.
From our budget models to the top-of-the-line, we’re committed to using quality lenses. Our lower-priced cameras feature multi-element, plastic lenses perfectly paired for the sensor in the camera. In our mid-price webcams, you’ll find glass lenses that produce even sharper images.
For our best webcams, we teamed up with Carl Zeiss®—a pioneer in the world of optics—to create lenses that raise the bar for image quality. They use glass instead of plastic and have five elements to give you more detail and clarity and less distortion.

Ready for your close-up? You’re not only going to need a good lens—you’re going to need a good focusing system. A lot of webcams have either a manual focus option or no focusing system at all. If you get too close, you can end up fuzzy.
Our top webcams feature an advanced autofocus system. You’ll get crystal clear images and fluid transitions whether you’re moving in for a kiss or your kid is holding her latest masterpiece up to the camera—as close as 10 centimeters away.

What about HD webcams?
When it comes to video calls, the maximum resolution is 640-by-480 pixels, otherwise known as VGA resolution. Today, you can’t make an HD video call on any of the free instant-messaging applications.
So what’s the value of an HD webcam? Want to record a message to a friend? Update your blog with a video clip? Capture your latest dance moves and post it on YouTube™? An HD webcam can record HD video. And several Logitech webcams make it easy to capture HD video at the 720p standard.
Power and connections
Most computers sold today have no problem handling a video call. But if your computer is a little bit older or you’re not using a fast connection, you might run into difficulty. To get good clarity and smoothness, your computer needs to meet the minimum requirements to support a video call.
We recommend that your computer have a dual-core CPU with 1 GB of RAM and that you’re using a broadband connection of 256 kbps or higher. (Most broadband connections are at least twice as fast as 256 kbps.)
