Designed for in room PC solutions

Meeting room video solutions based on an in room PC and often a control pad, are simple to operate and a preference for many IT departments. Popular options are the preconfigured Microsoft Teams Rooms and Zoom Rooms, while some choose a more open platform approach. But to bring the system to life a high quality conference camera and speakerphone needs to be connected. The Konftel C20800 Attach video kit works with all in room PC variants.

A wider picture

The Konftel Cam20 is optimized for situations where the conference camera needs to be positioned close to the table. The 123° field of view means that all the participants can sit in a comfortable position and still fit into the video image. At the same time, the camera creates a realistic image with no distortion. The Konftel Cam20 is equally at home in small, medium-sized and even large rooms thanks to its 4K capabilities.

The camera is quick and easy to mount in the meeting room. Use the flexible clamp to attach it to the screen or screw the base onto a stand in the perfect position.

OmniSound for power and clarity

Konftel’s refined audio platform OmniSound® with beamforming microphones works actively to keep the dialog flowing in your meeting. In the scalable Konftel 800 conference phone, the result is particularly powerful and clear sound that allows participants to relax, knowing that they can hear well and be heard. This creates a natural sense of presence.

Maximize audio placement

The Konftel C20800 Attach kit comes complete with a special 10 meter active USB audio cable, to reach back from the PC in front of the room to the speakerphone for central placement on the table.

Impressive video quality

With the Konftel Cam20 USB conference camera, a clear and balanced image is assured. WDR technology automatically adjusts to achieve a great picture in different light conditions, even challenging ones such as low light, direct sunlight and high contrast.

4K video resolution also allows for a superb digital zoom. Even at the maximum 8x zoom, the camera is still perfectly capable of producing a detailed image. 

Perfectly framed all the time

With auto framing, room participants will always be ideally fitted within the picture. This removes the need to manually crop the image with the digital zoom. If someone leaves the room, the framing cleverly readjusts. The feature can be disengaged if required.

How it works

This is how the components of the room solution fit together: The Konftel C20800 Attach complements the main computer, which is controlled via a touch panel or wireless keyboard and mouse, and connected to the screen. The high quality camera and audio device bring the system to life, with a 10 meter active audio cable maximizing speakerphone placement.

Konftel Smart Microphone

With the Konftel Smart Microphone, you can expand the pick-up range to handle larger conferences. Connect one or two expansion microphones, depending on the size of the room. The Konftel Smart Microphone has built-in cancellation of echo and background noise through OmniSound®.

A smarter way to lecture

Connect an approved* wireless headset to the conference phone. The Konftel 800 supports Lecture Mode from software version
This gives the presenter total freedom of movement and position in the room. Everyone will hear clearly all the time. 

While the presenter is speaking, the Konftel 800 will automatically mute all device microphones and only keep the headset microphone open. When the person stops talking, the speakerphone microphones are unmuted and all participants in the room can be heard. But through the headset, the remote participants can always be heard. Pretty smart, and a bit unique.

* See the interoperability list on the Konftel 800 support page for approved headsets.

”The Konftel 800 does a good job of addressing audio challenges and of integrating multiple devices and collaboration platforms into meetings. It is a safe, future-proof choice in most situations.”
