Webcam Buying Guide
Types of Webcams
Webcams with Microphone
Webcam Buying Tips:
• Consider an external webcam with a built-in microphone
• Pricier HD webcams have tilt, pan and zoom capability
• Look for at a frame rate of at least 30 fps to support full HD
• External webcams are available as either clip-ons or free-standing units
• Make sure your computer has a USB or other compatible port to plug in your external webcam
Online video chat looks best in high definition (HD). An HD webcam is practically essential for business video-conferencing. Standard-definition webcams, while more affordable, produce a lower-quality image that's less enjoyable to watch and may cause viewers to miss details in a presentation. Keep in mind, the quality of your webcam helps determine the quality of their picture.
Frame Rate +
Frame rate refers to the number of still images a video camera takes in one second. Frame rate and resolution work hand in hand to determine the quality of your webcam's picture output. The best personal webcams combine full HD (1080p) with a frame rate of 30 frames per second to produce a clean, smooth picture. A slower frame rate can cause inferior image quality and even cause your image to break.
For superior picture quality, choose a glass camera lens over the plastic lenses found on some webcams. Higher-priced webcams use the same optical glass used in high-end still cameras, though you don’t necessarily need top-notch Swiss optics if all you're doing is online video chatting with friends and family. A good quality glass lens will also perform better in low light.
Not every webcam has a built-in microphone, but it makes sense to buy one that does. The extra cost is often nominal when compared to the cost of purchasing a webcam and microphone separately. And don't forget that a separate computer microphone needs its own input port on your desktop computer. If you require have a separate mic, there are plenty of options available, including high-end models designed for recording professional quality audio. Noise reduction is a valuable added feature to cancel background hiss.
Most external webcams connect to your computer via a USB port, but wireless options are available. After you’ve installed the accompanying software, most webcams are plug and play, meaning they are immediately recognized by your computer. Should you ever change or upgrade your computer's operating system, you may also have to update your webcam software to keep the device working properly. To disconnect an integrated or internal webcam, you need to go into your computer settings and disable the device driver. An external webcam is easier to disconnect as you simply unplug it from the back of your computer.
Noise Reduction +
Analog and digital transmissions produce signal noise that can degrade and distract from the audio portion of your video chat — unless it's cancelled by noise reduction technology. You’ll pay a bit more for a microphone with noise reduction, but it’s worth the cost for clean, clear sound during important business chats and conversations with loved ones.
Most integrated webcams are set in a fixed position. If you require the flexibility to move your webcam around, you'll need to pick up an external webcam; just remember to first disable your internal webcam's device driver and then install the new webcam software, so your computer recognizes the new equipment. External webcams come in two styles. Clip-ons attach to your monitor and free-standing models are designed to be placed on a flat surface. Free-standing webcams are generally better suited for moving around and shooting different angles.
Autofocus (facial tracking) +
Autofocus can dramatically improve the video chat experience by preventing your image from blurring every time you shift your position in front of the camera. Autofocus locks onto your face and follows it for the duration of the conversation, so the picture remains smooth and sharp. Webcams lacking this feature inevitably take longer to set up prior to each chat and can lead to less enjoyable chat experiences.
Range of View +
Your webcam’s range of view, or field of view, from side to side is measured in degrees. Most webcams are fixed-lens cameras and their range of view is determined a sensor. In general, fixed-lens webcams have a range of view of 50 to 60 degrees, which is adequate for video chats. Unless you have a specific need for a wider range of view — such as capturing the whole family on screen at the same time for holiday video chats — having a wider range of view is not likely to be a significant factor in your buying decision.
