Videoconferencing (the live communication of two or more people or groups using a combination of video, audio, and data) for any but the largest of organizations hasn't enjoyed good quality in the past. Most first- and second-generation systems offered high cost, less-than-TV-quality video, complex user interfaces, and low reliability. The most recent generation of videoconferencing appears to be better in all these areas.
The most successful use of videoconferencing in libraries has been in continuing education for librarians by consortia and state library agencies. INCOLSA in Indiana and the Iowa State Library both make extensive use of the technology. They have invested in top-of-the-line group videoconferencing equipment and have staff skilled in operating and troubleshooting the hardware and software. Those being trained come to sites that serve an entire geographic area, rather than participating with equipment in their own libraries. In Iowa, most of the videoconferencing rooms are in special classrooms in community colleges.
Individual libraries may want to invest in desktop videoconferencing units for a group of up to six people. At least eight desktop videoconferencing systems are available for under $12,000. Video quality has dramatically improved now that most systems have standardized on the high-quality Sony EVI D3O/31 video camera. With good optics, a built-in pan, tilt and zoom capabilities, this camera compares to the best of consumer camcorders. Microphones and user interfaces have improved, including simpler screens and handheld remote controls. Reliability has increased, too.
Among the best products are Polycom's ViewStation MP and VCON's MC8000, both priced at just under $12,000. Avoid low-end systems such as VTEL's SmartStation and PictureTel's P550 because they do not use the same quality camera and microphone included in the high-end systems.
Find current information about companies and products by searching the Web under videoconferencing. When investigating videoconferencing, don't overlook the bandwidth requirements. They are substantially greater than libraries with automated library systems and Internet access have come to expect.
