I. Industry Background

Driven by China’s comprehensive national strength growth and rapid advancement of modern information technology, enterprises and institutions are raising higher standards for office informatization. Traditional meeting rooms, merely used for listening and communication, have evolved into multi-functional comprehensive hubs for information exchange. Equipped with projectors, video recording devices and professional audio systems, modern conference facilities feature richer functions and more professional configurations while keeping operation intuitive for ordinary staff.

Modern office buildings accommodate multiple departments and even cross-enterprise shared meeting spaces. To maximize room utilization efficiency, centralized management, unified scheduling and pre-meeting online reservation notification become essential.

II. Project Requirements

Multimedia Conference System for Intelligent Building

Following the design principle of demand-oriented, forward-looking, feasible and sustainable development, the integrated conference system supports daily meetings, video conferences and multi-purpose events with advanced architecture, stable performance, complete functions and efficient centralized control.

1. Optimize structural design to realize cost control under precondition of advanced, reliable and cost-effective system configuration.

2. Clear visual display for all attendees; PA system complies with national standard for speech reinforcement to deliver bright, intelligible voice, and the whole intelligent system meets relevant national specifications.

3. Precise acoustic localization without sound deviation; convenient wireless handheld microphone for free speaking.

4. High-sensitivity digital conference discussion microphones; chairman unit supports priority talkover function.

5. Seamless audio & video switching to adapt various signal sources and diversified application scenarios.

6. Built-in remote video conference function to facilitate cross-regional briefing, discussion and task deployment between headquarters and branches for higher working efficiency.

7. Full HD recording system to archive audio-video footage of important conferences, supporting on-site live streaming, post-event on-demand playback and educational resource sorting.

8. Integrated centralized control unifies lighting, large screen and AV equipment; one-touch preset scene control via tablet simplifies complicated operation procedures.

Conference Administration Management for Intelligent Building

IV. Design Solution

Multimedia Conference Hardware Deployment

1. Small meeting rooms adopt 65~98-inch all-in-one interactive displays integrating electronic whiteboard, video display, built-in audio and soft-video conferencing function. For larger rooms, appropriate LED screen size is selected based on room dimension and viewing distance to guarantee clear visibility for all participants.

2. Compared with performance-focused multi-function halls, meeting room PA design is easily overlooked, yet premium acoustic environment delivers comfortable volume, transparent speech and accurate sound localization for natural face-to-face communication. Designed in accordance with GB/T 28049-2011 National Standard for Hall Sound Reinforcement, the system applies stereo background music + mono microphone setup; main and auxiliary speakers are uniformly angled to ensure over 98dB sound pressure and below 8dB steady-state sound field unevenness at rear seating. SK-525U dual-pack wireless microphones serve roaming temporary speeches; 5G wireless digital conference system with auto-tracking camera features flat frequency response, low distortion and long pickup distance to accommodate various speakers.

3. Hishico recording system is configured to archive important conference footage, supporting real-time interaction, remote guest access and post-event on-demand playback amid frequent corporate meetings.

4. Point-to-point remote video conference solution requires no extra MCU equipment, enabling seamless cross-company and cross-regional real-time communication between headquarters and subsidiary branches to boost coordination efficiency.

5. Central control system unifies all AV devices with intuitive operation interface, helping non-professional in-house operators manage all conference equipment without complicated technical training.

Cloud-based Conference Administration Platform

Supported by cloud computing and internet technology, the cloud conference management system provides reservation and daily management services via mobile APP and WEB portal, realizing standardized full-cycle management covering pre-meeting booking, in-meeting execution and post-meeting statistical analysis.

Real-time room occupancy status is visible on management dashboard; reservation reminders are pushed via WeChat, DingTalk and Email; dedicated digital display terminals at lobby and room entrances publish real-time meeting schedules.
