(20) Multi-scenario one-touch access: The system features open programming capabilities to customize frequently used meeting scenarios based on user habits, such as Projection Mode, Discussion Mode, and Video Conference Mode. Users can instantly enter preset meeting scenarios by pressing the mode button.

(21) Intelligent, User-Friendly Applications: When paired with peripheral sensor modules, the system enables real-time monitoring of indoor temperature, humidity, air quality, smoke, and fire alarms. This data is synchronized to the touchscreen interface. Should indoor temperature or air quality exceed thresholds, the system automatically activates the air conditioning to regulate airflow and temperature. (Requires optional environmental sensor module; software interface diagram provided as proof)

(22) Automation and Scheduled Timing: Simple and rapid programming enables the system to support any scheduled trigger events, including annual, monthly, weekly, or daily timings down to the minute. For example, automatically activating meeting room lighting, display terminals, DVD playback, and opening curtains at 8:00 AM daily. Additionally, it supports triggering one or more events with a delay after any scheduled time, executing all events sequentially according to user-defined settings. (CANS inspection report provided)

(23) Seamless Human-Machine Interaction Experience: The interface can be customized based on user preferences for color schemes, layouts, and usage habits. Real-time status updates for all conference room equipment are displayed synchronously on the interface, complete with video signal preview functionality. This enables users to monitor every detail within the conference room directly from the control terminal. (Software interface screenshots provided)
