Meeting Room Audiovisual System with AV over IP & Environment Control System
SC&T's partner, XinCheng System Co., completed another conference room control system for a private company at the beginning of 2024. The largest conference room fits 43 people, the medium-sized room holds around 12, and the small room seats about 6. This control system includes video, audio, microphones, PTZ cameras, and a control host as the main operation. A control panel or a mobile phone app can accomplish all conference room settings and audio/video configurations.
The project's audio/video system adopted SC&T's network distributed matrix, AV over IP, as the video transmission architecture. Users can integrate and broadcast the desired videos effortlessly, with the control host easily controlling all systems in the room. In addition, the PTZ cameras automatically track and project the speaker's image onto the screen within only one second.
AV over IP Architecture for Conference Rooms
When installing AV over IP systems in conference rooms, system integrators will make slight adjustments to the architecture based on the size of the room.
Small/Medium Conference Rooms
HDMI and USB cables have a transmission limit of 5 to 10 meters. With an AV over IP system, these signals are extended up to 100 meters over a network cable, back to the network switch in the cabinet, and connected to the control host.
Since small and medium conference rooms require fewer devices, the hassle of additional extensions can be eliminated. For example, the transmitters were installed on the ceiling to transmit camera signals to the cabinet through network cables. To meet the BYOD requirements, embedded extenders in the conference table send computer signals to the cabinet, and the transmitter converts them to IP signals.
RS232 signals, on the other hand, use the transmitter in the cabinet to directly connect to the control host.
Large Conference Room
The layout of large conference rooms is more complex. Due to the large number of devices, it is necessary to manage all of them in the cabinet. Therefore, equipment installed in the conference room and users' personal computers are all distant from the cabinet. In addition to the AV over IP system, each device at the front end is equipped with different HDMI and USB extenders according to needs. Once there is a problem with the configuration of the control system, it is possible to quickly check the AV over IP system and other equipment such as mixers, amplifiers, and recording computers.
Auto-Tracking PTZ Cameras
Camera Image Sent to the Computer and AV over IP System
The integrator used three AVer cameras with USB and HDMI dual outputs. The USB port of the camera is connected to the recording host computer using a USB extender (UE02H). The HDMI port is connected to the network switch in the AV over IP system using HKM02B. This allows the camera image to be used alone on the projector or the computer for remote video conferencing.
Through the media switching function, we can see the camera image transmitted to the computer via USB and the camera image input to the AVoIP system via HDMI.
HDMI Seamless Switching
The auto-tracking camera works with a seamless switching device to instantly show the speaker's image. SC&T AV over IP supports a seamless switching function, allowing the switching to speakers when they press the microphone button.
RS232 Control
SC&T AV over IP can control all AV over IP devices through the switch and network cable by connecting RS232 to the control host through the receiver. All transmitters and receivers have RS232 ports. Connect any AV over IP device to the control host, and the host can control all transmitters and receivers connected to the network switch.
Touch Panel
SC&T provides a full list of RS232 commands. By writing the required commands into the system, the touch panel can be used to control all the overall settings of the entire conference room:
AV switching
Screen up/down
Power on/off
Volume
Camera
Auto-Tracking Camera
Three cameras are installed in this conference room. The automatic focus coverage area can be written into the settings. Through the control system, the camera locks onto the speaker who presses the microphone button and projects the image onto the screen.
HDMI Interface in Table
The information box on the conference table has a built-in HDMI extender. Meeting participants can use their devices to send images to the AV over IP system for playback. The lights on the information box can display the connection status so that users can easily understand the connection status.
Conference Room Cabinet
Our system integration partners use 1U racks.
Clear Device Status with Racks
To organize the devices and enhance the visibility of connection statuses, the integrator employs SC&T's AV over IP 1U rack panels. These panels feature illuminated indicator lights, facilitating rapid assessment of device status during installation or maintenance. Each port on the rack panel is clearly labeled, and the panel can be securely fastened to the rack cabinet for added stability.
SC&T has been doing a great job in providing products with stable performance. In this project, the AVoIP system once again helped us to build the complicated A/V system. During the installation, SC&T was very helpful to provide insightful suggestions and solve technical issues for us. It's another great experience working with the company.
