## Hardware, software and related product brands
### Videophone hardware brands for person-to-person (point-to-point) use

Stand-alone videophones are point-to-point units not employing Multipoint Control Units (centralized distribution and call management systems). Earlier models make video calls utilizing older analogue POTS telephone lines, while later models use newer, higher quality, ADSL, ISDN or cable broadband technologies. Some videophones also employ Internet calling (IP) capabilities which can dispense with the need for telephone service.

## Videotelephony descriptive names and terminology

The name [videophone]is not as standardized as its earlier counterpart, the telephone, resulting in a variety of names and terms being used worldwide, and even within the same region or country. Videophones are also known as videotelephones (or video telephones) and often by an early trademarked name "Picturephone", which was the world's first commercial videophone produced in volume. The compound name "videophone" slowly entered into general use after 1950, although "video telephone" likely entered the lexicon earlier after "video" was coined in 1935.
Videophone calls (also: videocalls and video chat), differ from videoconferencing in that they expect to serve individuals, not groups. However that distinction has become increasingly blurred with technology improvements such as increased bandwidth and sophisticated software clients that can allow for multiple parties on a call. In general everyday usage the term videoconferencing is now frequently used instead of videocall for point-to-point calls between two units. Both videophone calls and videoconferencing are also now commonly referred to as a video link.
Webcams are popular, relatively low cost devices which can provide live video and audio streams via personal computers, and can be used with many software clients for both video calls and videoconferencing.
A videoconference system is generally higher cost than a videophone and deploys greater capabilities. A videoconference (also known as a videoteleconference) allows two or more locations to communicate via live, simultaneous two-way video and audio transmissions. This is often accomplished by the use of a multipoint control unit (a centralized distribution and call management system) or by a similar non-centralized multipoint capability embedded in each videoconferencing unit. Again, technology improvements have circumvented traditional definitions by allowing multiple party videoconferencing via web-based applications. A separate webpage article is devoted to videoconferencing.
A telepresence system is a high-end videoconferencing system and service usually employed by enterprise-level corporate offices. Telepresence conference rooms use state-of-the art room designs, video cameras, displays, sound-systems and processors, coupled with high-to-very-high capacity bandwidth transmissions.
Typical use of the various technologies described above include calling or conferencing on a one-on-one, one-to-many or many-to-many basis for personal, business, educational, deaf Video Relay Service and tele-medical, diagnostic and rehabilitative use or services. New services utilizing videocalling and videoconferencing, such as teachers and psychologists conducting online sessions, personal videocalls to inmates incarcerated in penitentiaries, and videoconferencing to resolve airline engineering issues at maintenance facilities, are being created or evolving on an ongoing basis.
