Nelt's modern distribution center was opened in Dobanovci in 2006, and it is in the same location today. We have recently had the opportunity to improve it with an efficient video presentation and conference system easily manageable.

Together with our partner, the company Communify DOO, our project-engineering team implemented a solution that fully meets the wishes and needs of the client.

The central part of the presentation system is the Infobit IMATRIX H88A matrix switcher with 8 HDMI inputs and outputs, which distributes video signals from the computer and camera to Sony FW-85BZ40H/1, 4K presentation displays. They feature high brightness, which makes the content crystal clear even in high ambient light. Since they are mounted on trolleys, they can be easily moved to any part of the hall as needed. The supplied Infobit iCAM P20 PTZ with automatic speaker tracking features 12x optical zoom and supporting 4K60 display resolution.

The wireless collaboration system Infobit iShare+ enables the simultaneous display of multiple users on presentation displays via free application for mobile devices or USB dongles that present content from a computer with just one click.

The existing tables in the presentation room can be disassembled and configured as desired, and have 5 connection points with HDMI, USB and RJ45 connectors, USB charger and sockets. As part of the video presentation system, a wall-mounted control system with buttons is integrated, which enables a simple selection of content display from the connection points in the tables via IP and RS232.

The system is resistant to all types of electromagnetic radiation in the space that are always present due to the use of mobile devices, which guarantees a stable and high-quality connection at every moment.

For video conferences with multiple participants, a Televic D-Cerno audio conference system with six desktop units and a central Televic D-Cerno CU unit integrated into the video conference system was installed. The system consists of Audix AP61 OM5 wireless microphone systems with hand transmitter and AP61 BP bodypack with lavalier.

Complete audio processing with all algorithms for eliminating sound interference and echoes is performed through the DSP digital Symetrix Solus NX 16x8 audio processor, from where the signal is sent to the RCF amplifier and three-system RCF L 2406T column speakers. Thanks to their coverage angle of 150x30°, the audibility and intelligibility of speech in the conference room is excellent.

All microphone, speaker, video and command installations were realized using Sommer Cable halogen free cables with maximum protection against possible RF interference.

After the installation was completed, our team trained the client's technical stuff to manage the audio-video conference and presentation system.
