With a good computer and a broadband internet connection, web cams make the dream of video telephony a reality. Web cams have been around for a long time, but it hasn't been until recently that internet connections were fast enough to support true streaming video. If you're in the market for a web cam, there are a few factors you should consider so that you pick a unit that meets your needs--and your budget.

Things to Consider When Buying a Web Cam

The main factor that determines the price of a web cam is the unit's resolution capabilities. Cheap web cams are available for less than 20 dollars, but they usually can only produce resolutions of around 640 x 480 pixels for photos, and 352 x 288 pixels for streaming video. This isn't bad, but it's not good enough for nice-looking streaming video conversations.

Another thing to consider when shopping for a web cam is whether or not you need a microphone. Let's say you're looking for a web cam to serve as a security camera. You can hook it up to a computer at your business and have it broadcast a signal to the Internet that you can monitor from any computer, anywhere in the world. In a situation like this, you probably only need a low-resolution camera. A microphone probably isn't necessary, unless you want to hear what's going on as well.

If you're interested in setting up video conferencing calls, a slightly better model is probably in order. You'll want a web cam with at least 640 x 480 video resolution that also has a built-in or external microphone. This allows you to set up calls quickly and easily, without having to worry about a separate audio system.
