VS-400 (discussion wireless conference system)

Main features
1. Unlimited conference units with one drag
2. Can remotely control host functions and monitor conference unit status
3. The unit can have chairpersons and attendees
4. (With the chairman priority function), the meeting can be better controlled
5. The exquisite short pole design does not block the line of sight, and the pickup distance is up to 80cm, which is clear and clear.
6. Equipped with automatic frequency scanning function, the host radar scans the surrounding environment for radio waves and automatically selects a frequency without interference to use.
7. Full U-band wireless network coverage does not require any connections from the host computer to the conference unit to the central controller.
8. Wireless frequency binding technology, the number of conference units can be increased at any time.
9. Conference mode (chairman priority/rotation mode/restricted mode)
