Features :
The system integrates discussion conference, video tracking and voting function in o one, and cooperates with video tracking + voting speaking unit to realize video tracking, voting and dynamic sign-in functions. Hand-in-hand connection, high definition, high fidelity sound quality. It can be connected to the computer, and the operator can easily control the venue with the help of the corresponding software, or can be used away from the computer. Including camera preset position setting, microphone management, representative sign-in, voting control, data display, etc. Video tracking can be done fully automatically or manually. The system host has a feedback suppression function to effectively prevent howling. It can be equipped with simultaneous interpretation and infrared emission host VA-6912 to realize infrared simultaneous interpretation.
Conference discussion :
Based on Thinuna Net-Stream digital communication technology, it has built-in high-performance CPU according to IEC60914 international standard, digital design, more stable system and faster calculation. It has four sets of 8P-DIN microphone connection interfaces, which can support 15×4 groups=60 speaking units, increase the expansion host can connect up to 240 speaking units.
Host priority
The speaker number limit function can set the speaking unit that is turned on at the same time (the number is 1-9, the number of software can be set 1-12)
Unlimited discussion mode (all microphones can speak)
FIFO, after reaching the limit quantity, the last open unit covers the earliest open unit (1 to 9 pieces, software can be set 1-12)
Signal I/O and panel control:
1*line main output interface ,independent volume adjustment
1*Recording output, independent volume adjustment
1* Telephone interface, independent volume control
1*data interface
4* Conference microphone output interface, one of which is an extended host conference microphone output interface
With treble gain adjustment knob
LED volume level indicator
Dedicated T-type 8P-DIN connecting cable
Output supplied to speaking unit is 18VDC safe voltage
Conference video tracking:
Built-in video switching matrix (8 input 2 output)
Up to 512 camera position tracking control points in a single unit
Support two high speed cloud ball protocols. (Pelco-D baud rate 9600, VISCA baud rate 9600)
The central processing unit can communicate with external devices such as a computer or a video switching matrix through the RS-232 port, and has a linkage control function.
The high-speed dome camera tracks the last opened microphone position in all the delegates. When the last opened microphone is turned off, the high-speed dome camera tracks back to the previous tracking point.
Supports high-definition camera balls, which can be selected according to different HD interfaces (HDMI or RGB matrix).
Digital design for use with video tracking setup software
Can display camera number, preset point, speed and other parameters
Programmable preset points, auto cruise, etc.
Support RS-232, RS-422 control protocol, control distance up to 1200 meters
Meeting vote
The 5-button voting button can implement multiple voting modes (only with voting function unit):
Voting method: approval/ abstained / objected;
Election method/investigation method: choose one of the five candidates (1/2/3/4/5);
response: Evaluate something or evaluate someone (--/-/0/+/++);
Grading method: Evaluate something or rate someone (0/25/50/75/100);
