Videoconferencing Systems and Cameras

Digital Video Enterprises designed the Huddle Room 70 as a complete videoconferencing system to accommodate up to four participants at either end of the transmission or up to eight people arranged in two rows. The system allows them to appear to be in the same room by including a zero-frame 65in.-70in. HD flatscreen with HD and PC inputs as well as eye-level embedded camera(s) so that the participants can sit very close to the screen with natural eye contact. Each room comes with a boardroom-quality table custom made for each client and provides 21in. data tablets on the table for up close and easy-to-read text. There is an option for Intelligent Switched Telepresence with multiple cameras, and the Huddle Room 70 is also designed to work with any HD codec so that it can be incorporated into many existing systems as a significant upgrade.
Quick, easy setup and operation is the idea behind LG’s V5500 Multi Video Conference System with its intuitive interface, simple hardware, and ability to connect with a wide range of existing display devices. Dual streaming allows simultaneous on-camera communication and HD content sharing using minimum bandwidth. The GUI preset feature provides thumbnail images on the buttons so that users can easily identify the preset shot they are taking with the button push. Up to four sites can be called to participate simultaneously while the 3M CMOS camera system shows 1280x720p30 video and employs a 12X optical zoom and auto focus. The complete system consists of the conference codec, HD PTZ camera, remote control unit (RCU) with AAA battery, mic pod, and cabling. Sound system features include echo cancellation, auto noise reduction, auto gain control, and full duplex transmission.
The LifeSize Room 220 is a very compact videoconferencing solution that can be taken virtually anywhere and set up in minutes. With point-to-point throughput of 8Mbps, it has an eight-way continuous-presence multipoint bridge with transcoding and all-digital I/O. The system includes the HD PTZ LifeSize Camera 200 or the LifeSize Camera 10x, the LifeSize Phone 2nd Generation, wireless remote, and all connecting cables. All multi-party calls and data sharing are controlled on the touchscreen interface of the LifeSize phone while the video output shows a display on one or two DVI or HDMI input monitors in 1920x1080-30fps or 1280x720-60fps. System inputs include the camera, two HDMI inputs, one DVI-I connection, one component/composite, and one S-video in. There are two HD video outputs. The sound system features echo cancellation, full duplex transmission, automatic gain control, and noise reduction. The LifeSize Room 220 also enables recording and streaming of all conferences.
The KX-VC600 from Panasonic can connect up to four sites with two HDMI inputs for cameras and a VGA input for computer data sharing while showing the video output through HDMI and component connections. Its Multipoint Control Unit ensures interoperability with other videoconferencing equipment, and it is capable of using bandwidth down to 1.2Mbps for video communication. The unit has a digital audio input for use with the KX-VCA001 digital boundary microphone (up to four can be used) and an analog audio input for use with the KX-VCA002 microphone. A stereo mini input can connect a headset, and there is also an RCA line level audio input jack. The rear panel has a 9-pin RS-232 terminal for operation through a room control system in addition to the infrared remote. Audio outputs include HDMI, stereo mini for headset, and RCA for an external sound system. Panasonic has both HD fixed position and PTZ cameras available for the KX-VC600 as well as HD displays.
At the top of the Group Series videoconferencing systems from Polycom is the Group Series 700 with SmartPairing technology to allow participants to use their own tablet to start and manage video calls. Delivering 1080p60 HD video, the system provides simultaneous dual-stream transmission for participants and content sharing. An optional user interface is the Polycom Touch Control, presenting a graphical user control layout on a 7in. screen. The operation is standards-based including Telepresence Interoperability Protocol (TIP) support and H.264 High Profile to connect to a variety of existing systems, and it features native interoperability with Microsoft Lync. Polycom’s interoperable Scalable Video Coding (SVC) architecture is the first to provide video calling between both existing video systems and new SVC systems. The setup includes the Polycom EagleEye III camera, codec, Polycom RealPresence Group Microphone Array, cables, and remote control. Two cameras can be used, and there are three HDMI inputs, component, and VGA.
