The system automatically triggers PPT signal switching without requiring any auxiliary software or plugins.
It enables playback of local hard disk videos, USB video files, and remote RTSP video streams for recording. Featuring 12 customizable split-screen layouts, users can freely configure their preferred split-screen configurations.
Equipped with a built-in digital audio processing module, it performs intelligent audio processing without external processors, supporting echo suppression, noise cancellation, and automatic gain adjustment. The system requires ≥2 MIC inputs (with 48V phantom power), ≥1 line input, and ≥1 line output.
Three LED indicators monitor server status: a constant-on power indicator, a flashing hard drive indicator during read/write operations, and a running program indicator.
The recording system emphasizes simplicity, user-friendliness, and high integration.
The system supports one-click live streaming, with manual and automated modes that can be freely switched. The manual mode offers video preview, live output pre-monitoring, video switching, audio adjustments, and recording mode switching.

In conference scenarios, it features automatic file restoration during power or network outages.
Practical functions include OSD information display, angle markers, and real-time editing of opening/closing sequences.
For daily recording needs, the system provides ≥2TB storage with a maximum of 8TB available.
FTP/NFS connectivity enables automatic file transfer to third-party cloud storage servers.
To ensure stability of recording equipment, the recording host must adopt an embedded architecture design. It does not accept server or PC architectures and avoids using encoding boxes. The host integrates local and remote directing functions, recording, live broadcasting, on-demand viewing, video resource management, user management, as well as digital audio and amplifier capabilities into a unified system. Featuring Web-based remote management with real-time monitoring capabilities, the recording host's exterior design should meet aesthetic, practical, and installation convenience requirements. The equipment is required to be ≤1U in height. The front panel contains a 2-inch LCD display that shows device model, meeting room name, IP address, operational status, temperature, date/time, and disk space. Users can configure network settings and system time. Powered by 12V DC.
