Advanced and professional AV Integration and conference solution supplier



Standard & Protocols Enable Convergence  

Standard SIP and H.323 protocols supported; compatible with  the industry's mainstream standard terminals and networked  devices.

Standard & Protocols Enable Convergence 

Standard SIP and H.323 protocols supported; compatible with  the industry's mainstream standard terminals and networked  devices. 

Embedded DSP Solution 

Embedded DSP hardware solution offers high efficiency and low  latency. 

Multiple Microphone Connection 

Various audio inputs such as digital microphone, USB  microphone, and analog microphone are supported to  suit different conference scenarios and meet more audio  requirements. 

Excellent Network Security 

H.460 firewall traversal supported to guarantee the secure  connection of public and private networks.  H.235 and SRTP protocols and the encryption algorithms  such as AES-128 are supported for all-round guarantee for  communication security. 

Low Bandwidth, and High Definition 

The latest H.264 HP coding standard supported; 50% less  bandwidth than the previous-generation compression standard. 

1080P Full-HD 

1080P full HD supported; multiple (HDMI + DVI-I: HDMI and VGA)  HD video inputs and 2 HDMI HD video outputs are supported. 

Supported Simultaneous Bilingual Audio Signals

Simultaneous bilingual audio signals are supported; This  terminal support simultaneous input /output of voice in two  different languages and the flexible mixing and coded output of  voice in two different languages. 

Built-in MCU (Optional) 

Built-in MCU (optional) support up to 1+3 terminal HD video  conferencing, ideal for small- and medium-sized enterprises that  require low cost and simple maintenance of video conferencing. 

Infrared Passthrough 

IR signals can be received via serial ports for the terminals; for  operation of cameras of designated models, the IR control signals  are received through the cameras; all conference terminals can  be controlled even if the device is hidden. 

Local and Remote Recording & Broadcasting 

Remote recording and broadcasting are supported; conference  recording and broadcasting is realized with only one PC. USB  flash disk can be used to record and keep conference minutes  confidential. 

Fully Open API 

Fully open API supports the development of third-party  applications and is easy for secondary development by customer  to meet their customization requirements. 

Superior Anti-Packet Loss Zapability 

The proprietary FEC technology could be activated in the event  of severe network packet loss; the loss of less than 20% packets  has no effect on the system, and conferences can still go on even  if 30% packets are lost.

RTMP Push & Pull and RTSP Pull Streaming(Optional) 

The device supports RTMP push streaming to the live broadcast  platform for live broadcasting of conference. RTSP pull streaming  can be realized through web cameras.

Interactive Teaching Tracking 

Terminals + tracking cameras are arranged for the automatic  switching of teacher's images (close-up, panoramic) and  students' images (close-up, panoramic) to have smooth natural  interaction.
