3. Agent plan: The agent layout is saved as a plan, and the agent plan or single-screen plan can be called with one click.
4. Call intercom: point-to-point real-time voice intercom for agent users, one-click dialing call in address book.
5. Voice transparent transmission: The MIC sound of the agent node supports reverse penetration to the host computer of the signal source.
6. USB: Keyboard and mouse KVM application, USB camera access.
7. Converged communication: Support SIP/RTSP and other communication protocols to achieve agent video call function.

Massive monitoring docking

1. The distributed system can be configured with a multimedia convergence forwarding platform for forwarding and invoking massive surveillance video streams.
2. The security platform of various brands, the national standard platform and the monitoring equipment can be connected to the distributed system through the monitoring fusion server.
3. It supports GB/T-28181, ONVIF, RTSP, SDK, etc., and pushes video streams to distributed systems through RTSP, RTMP, SDK, and other video streams.
4. Support docking with security platforms such as Haikang, Dahua, Uniview, and Tiandi Weiye, as well as smart city platforms such as Skynet Engineering, Xueliang City, and Safe City.

Synchronous playback on the large screen

1. Distributed large-screen synchronous playback system for large-screen traceability and service playback.
2. Full-screen recording: The recording range covers the entire screen, and the content and scheduling of the screen on the large screen are fully recorded.
3. Whole process recording: signal windowing, moving, roaming, zooming and zooming are recorded throughout the process.
4. All-element recording: Record subtitles, audio, and system control commands on the large screen at the same time.
5. 1:1 Restore Playback: Restore the whole screen, the whole process, and all elements of large-screen scheduling, and complete business deduction and traceability.
6. Key event marking: Support key event dot marking, mark events to quickly jump, and make business traceability more convenient.
7. The system supports simultaneous recording of multi-screen groups and group recording of multi-screen groups.

Visualized O&M management platform

1. Visualized display of system status
2. Signal screen monitoring preview
3. Alarm information is released
4. Automatically generate a network topology diagram

High Score Sync

1. High-resolution multi-screen graphics card synchronization technology realizes multi-source synchronous encoding and synchronous decoding
2. Multi-screen graphics cards are grouped with multiple interfaces to collect and encode to ensure source synchronization
3. The decoder unifies clock decoding to ensure the synchronization of the full-screen display of ultra-high-definition images output by multi-port graphics cards
