ST-8830 Video Tracking Digital Wireless Conference System

Functional characteristics 1. Realize all functions wirelessly, get rid of cumbersome cable laying, move freely within the signal coverage, and easily and conveniently arrange the venue. 2. Fully automatic frequency alignment. The system is preset with multiple sets of different frequency band channels, and multiple sets of systems can be set up for use in the same venue to meet the needs of large-scale conferences, as well as to avoid mutual interference with other wireless products Built-in multiple sensors, wireless detection, wireless regulation, wireless matching, wireless encryption, and wireless automatic management, can help you complete your work smoothly without any assistance. 4. Automatic synchronization of radar frequency selection works. When the attending units are in the same address code, the main control computer changes the communication channel, and all attending units automatically follow the synchronization, eliminating the need for professional debugging and installation. The main control computer supports 168 non voting units, and the number of speakers can reach 4. The number of speakers can be set according to actual meeting requirements. 6. The main controller has a first in, first out, and chairman mode for speaking. 7. The main controller supports central control, and the microphone unit has the function of turning on and off microphone code sending. 8. The master computer can initiate the writing of unit ID addresses, and can increase or decrease the number of units as needed. This is flexible and convenient, leaving addressing cumbersome. The main control computer has the function of closing all conference units with one button, eliminating the need to manually turn off the unit power supply. 10. It has a dot matrix high-definition display screen and hierarchical menu design, making operation simple and convenient. Functions such as power display and undervoltage warning, frequency channel, signal indication, and operating status. 11. The main control computer and the camera realize network cable connection control, and the signal is transmitted remotely without interference. It can control and save the preset positioning of the camera. 12. The main controller has a built-in video tracking function, which can be used in conjunction with a video switcher to access up to 8 cameras simultaneously. It can also be used in conjunction with the central controller to achieve video tracking functions. The main control computer is equipped with a USB recording module, which can record conference content and automatically generate format files for saving. 14. Seamless access to non voting units, replacement or addition of non voting units at any time, without interrupting the meeting process. 15. The non-voting unit has a 20-level electronic volume button, which can control the volume in a timely manner without the need for background staff to debug.
