The E20 is an entry-level personal videoconferencing system produced by the Norwegian company Tandberg.
The E20 was introduced in 2008, and started shipping in Q1 2009. The system is intended as a replacement for traditional office telephones. It features a 10.6-inch (270 mm) LCD widescreen, a five-megapixel camera, CD quality audio and DVD-quality video.
As a standards based SIP system, the Tandberg E20 supports MPEG-4 AAC-LD for audio and H.264, H.263+, and H.263 for video.
The E20 is compatible with Tandberg's new large-scale provisioning solution, introduced in November 2009.
Tandberg were acquired by Cisco in 2009, and subsequently took over the Tandberg Video Conferencing line, integrating this within the Cisco Telepresence product line. The E20 was migrated to this portfolio, however was made end-of-life in 2012, superseded by desktop solutions such as the DX70 and DX80 product lines.
Tandberg was an electronics manufacturer located in Oslo, Norway (product development, sales and distribution) and New York City, United States (sales and distribution). The company began in the radio field, but became more widely known for their reel-to-reel tape recorders and televisions. The original company went bankrupt in 1978 after a sharp financial downturn. The company re-formed by selling off their tape recording side as Tandberg Data, who moved into the computer storage field.
Over time the original Tandberg company became increasingly involved in the teleconferencing systems, and became a leader in that field. The company's main competitor was Polycom and other competitors were HP, Sony, Radvision, VTEL and Aethra.
Cisco Systems acquired Tandberg on 19 April 2010. Tandberg Data is now officially a German company, and continues to make computer tape storage systems.
The company was founded by Vebjørn Tandberg as Tandbergs Radiofabrikk (the Tandberg Radio Factory) in Oslo in 1933. The company's first radio was named "Tommeliten", and used only earphones. This was followed by the "Corona" with a loudspeaker. In 1934, the first "Huldra" radio was launched, followed in 1936 by the "Sølvsuper". During the early years, radios, loudspeakers and microphones were the main output from the factory. The Sølvsuper and the Huldra radios became the foundation for Tandberg's success.
