Struggling to Videoconference

We try PC-based videoconferencing packages and get mostly disappointing results.

Why videoconference? Simple: to have face-to-face meetings while saving the time and money it takes to get employees together. The most obvious advantage is for those separated by long distances, but even getting a group together in a large building can often require significant time and resources--especially if you need to drag in equipment or presentation aids.

Many businesses can't afford a $40,000 videoconferencing setup with a 31-inch display screen. But there are a number of lower-cost PC-based conferencing products that cost as little as $199. Maybe one of these is the right solution for you. According to "What's Wrong With This Picture" in the forthcoming August issue, that's a really big "maybe." We tested a half dozen products for this issue, three priced under $350 and three that cost more than $1000. And we tried to test three other products that we couldn't get to work at all, even after extensive consultation with the vendors' tech support. We found that it's generally a struggle to get any of the packages installed, connected, and working.

What Do You Get?
All the packages include a digital camera, an ISA or PCI video-capture board, and videoconferencing software. As you might expect, we found that the higher-end products are more effective for business use than the low-ticket packages. The best products produce adequate video in Common Interchange Format windows of 352 by 288 pixels. Of course, that's pretty small: For example, if you're using a 1024-by-768 screen, the window would fill only about one-ninth of your display area. Our definition of adequate video is 15 frames per second. That's the maximum these products deliver--and at only half the rate of standard full-motion video, it's still on the jerky side. With a really high-speed connection, such as over a local area network, we found that we could get a pretty good look at a single subject's facial expressions. But forget seeing much detail if you're viewing a group in such a small window.

The worst packages were frankly terrible, providing tiny, blurred pictures, especially over low-speed modem connections or through a busy Internet service provider. The video on the low-end packages fell as low as one frame per second, depending on the speed of the connection. And the windows displayed were not much bigger than a postage stamp in some cases. So for most of us, it's not time to stop buying those airline tickets yet.
