3. It adopts H.265 data stream codec chips and is backward compatible to ensure the smooth operation of the system.

4. It is equipped with 2 HDMI interfaces, embedded with synchronous or asynchronous audio input, and supports port backup. When used as input, it supports 1 encoding channel and 1 loop-out channel. When used as a KVM seat or a splicing output node, it supports 1-channel decoding and is compatible with RTSP, RTMP protocols, and private protocols.

5. The audio input interface is embedded with synchronous or asynchronous input, supporting volume adjustment. It supports three modes: synchronous, asynchronous and mixing. It supports multi-channel audio mixing playback. It supports AAC, G.711, G.726, private protocols, CBR/VBR, and adjustable frame rate from 1 to 60fps.

6. Support audio visualization module management. Use sliders to control the output volume of each node. Audio energy bars can be displayed, and the audio status of nodes can be shown with animation effects.

7. Supports 1 optical port and 2 network ports for hot backup, supports dual power supply modes of POE and external power supply, and is equipped with input and output node switching switches, serving as two devices in one.

8. Supports 2.0"LCD display, which can dynamically display multiple layers of columns, IP addresses, names, signal status, temperature, network status, etc.

9. It supports the node roll call function. After the software selects a node, the node's LCD screen will keep flashing, which is convenient for locating the node.

10. It is equipped with 1 factory reset button, 3 USB 2.0 interfaces and 1 USB port 3.0 interface, 2 Gigabit Ethernet ports, 1 Gigabit optical port, 2 HDMI video input/output interfaces, 2 3.5mm audio input/output interfaces, 2 3-pin Phoenix terminal audio interfaces, 1 relay interface, 1 RS232 interface, 1 RS485 interface, 1 IR/IO interface, 1 IO interface;

11. Supports various signals such as HDMI, DVI, and VGA, with a maximum signal resolution of 3840×2160@30Hz. Backward compatible, supports fixed-rate transmission, adjustable range from 128kbps to 40Mbps, and supports unicast and multicast.

12. Ipc-encoded cameras that support H.264 and H.265, the signals of IPC network cameras can be directly output and displayed on large screens without the need for third-party transcoding servers, and support the zooming, pushing far, and left and right rotation of pan-tilt units, etc.

13. The system scenario can provide a one-click recovery function; The node device has programmable storage capabilities and can automatically restore the system to its pre-power-off state after a power failure and restart, such as volume level, large screen switch, signal position, lighting environment, etc.

14. It supports the classification, grouping and sorting management of signal sources. All signal sources can be managed in three-level groups and displayed in a tree form. They can also be sorted by name, IP or custom methods. The client software supports no less than 50 real-time dynamic image preview displays.

15. It supports one-click screen mirroring function, allowing the pre-arranged scene or picture to be synchronized to other displays with one click to show the same picture.

16. Supports mirror mode. You can set a mirror screen. When the main screen performs operations, other mirror screens follow the operation.

17. Support the linkage between tablets and seats. Any signal source can be pushed to the seat through the tablet to achieve linkage operation.

18. It supports button linkage function, enabling one button to control multiple buttons for box control and network control.

19. The function of displaying audio on the wall separately can be achieved through the visual control software to display audio on the large screen separately.

20. The function of prohibiting signals from being displayed on the screen enables the visual control software to prevent the signal from being shown on the screen after clicking the button, thus avoiding misoperation.

21. Annotation function: On the software end, you can mark the large screen with arrows, symbols, ellipses, squares, text, etc., and synchronize them to the large screen with one click.

22. It supports sleep and wake-up, and can push large screens from the agent end. Any video source in the list can be pushed to the local or remote spliced large screen for full-screen display through the local agent. It also supports window opening, roaming, superimposing, drawing, etc. Real-time preview of signal sources and virtual screens is available.

23. It supports video and voice intercom as well as text chat for agents. Agents can directly communicate one-on-one through video, voice and text. Supports inter-seat broadcasting. Seats can speak one-to-many or speak from the seat end to the entire hall environment.

24. Supports multi-party meeting mode, allowing 16 operators to enter the meeting interface simultaneously, and supports 16-channel mixing. Participants can be added or removed at any time during the meeting.

25. It supports the pre-operation mode at the agent end, allowing for layout in the virtual screen area. The process of adjusting the screen will not be displayed in real time on the large screen. When the push screen button is clicked, the adjusted layout can be displayed on the screen with one click to prevent accidental operations.

26. Supports remote KVM control, allowing the agent to remotely control the computers in the computer room and turn them on and off. It can simultaneously control up to 16 different signal sources. It has both manual and automatic start control modes.

27. Support mutual signal requests and push notifications among seats; Support three-level permission management; Support large-screen signal capture. Support large-screen partition management; Support the saving and retrieval of contingency plans on both the agent end and the large screen.

28. It supports multiple login methods (account password, fingerprint, and facial recognition login), and has a seat memory function. Seat personnel are not limited to the current seat. Logging in from any seat retains the original layout without the need for a new layout.

29. Support message queue prompts on the agent side; Signal up and down lines, other message delivery reminders, etc.
