1. Adopt WiFi5G communication technology, all digital frequency hopping (DSSS) modulation communication technology, and realize high-speed transmission of audio without compression through wireless audio data modulation algorithm to ensure audio delay less than 5.5mS.
2. The communication between the chairman unit, the representative unit and the wireless transceiver module and the host is encrypted with the 128-bit AES Rijndael encryption algorithm for the 48-bit PIN code, and the ID address is automatically numbered to ensure that the entire system will not cause embarrassment due to the confusion of the ID address.
3. The first 4.3-inch full-color touch screen with bilingual information display in Chinese and English, with dual functions of system navigation display and centralized control.
4. Built-in standard definition camera tracking board, (if you need to configure high-definition or 4K video tracking board need to book). Support SONY VISICA, PELCO-D/P, BO1 protocol, can access 8 cameras at the same time, through the external RS-485/RS-232 interface to connect the control part of the camera, you can realize the automatic camera tracking function or connect the programming central control system.
5. With 4 conference unit interfaces, each can connect 25 agent units, a single host can connect 100 agent units, (multi-function agent unit power is large, each route must reduce the number of connections according to power consumption);
6. Can access the expansion host to expand capacity, up to 512 expansion hosts, the maximum capacity of the system 51200 conference units, and no interference with each other;
7. Using ID to address the agent unit, the ID of the agent unit can be customized, and the function module and the online list of the agent unit can be automatically detected at startup, and the operation of the system can be monitored in real time;
8. The plug-in can be installed so that the host can access the wired conference agent unit and the wireless conference agent unit at the same time, so that the wired and wireless can be used at the same time, and the unified management of microphone mode, video tracking, voting and other functions can be realized;
9. With the number of restrictions, FIFO, speech application, voice control mode (optional) four working modes, the number of speakers can be set to 1 to 4, the executive chairman is not restricted, according to the application can join the free discussion and other speech management mode;
10. With Ethernet interface, standard RJ45 interface with connection status indicator light and signal transmission indicator light, support TCP/IP protocol using TCP/UDP transmission control, electronic table, voting, agent unit Logo and agent unit upgrade and other data, Connect to a wireless router to realize WiFi wireless communication;
11. With 2 standard RS-232 communication interfaces, support programmable central control system CCU, and SONY VISICA protocol control output, without external SONY VISICA control converter box (with video tracking function);
12. It can access conference management software, central control system, touch screen interface, wall control panel, large screen control system, PC, ipad, mobile phone, etc. for centralized control and management, two-way communication to achieve command control and status reading, and can establish a modern intelligent conference hall of science and technology;
13. The audio adopts 48kHz sampling frequency, and the frequency response of each channel can reach 20 Hz~20 kHz, with high quality CD-level sound quality;
14. The host can centrally adjust the output gain of the conference unit, and can set the audio adjustment lock;
15. Built-in environmental noise canceller (AEC), which can effectively eliminate local noise;
16. Built-in adaptive feedback suppressor (AFC), can effectively prevent whistling;
17. Built-in digital equalization EQ circuit, which can greatly improve the sound pressure level of the venue (optional);
18. The starting voltage, starting delay, mute delay, output gain and input/output volume of the system can be set centrally;
19. With RCA and Cainon audio input interface, can input external audio signals (such as background music, wireless microphone);
20. With RCA and Cainon XLR audio output interface, can be connected to the mixer, processor or PA amplifier to amplify the speaker's speech, can also be connected to the recording system, telephone conference system, etc.;
