H850 Video Conferencing Meeting Terminal
High Resolution and Smooth Streaming
  • The H850 provides a 720p/1080p resolution, smooth streaming with a frame rate of 70 fps, and high code processing capability with a bit rate of 8 Mbit/s.
Pleasure of Pure Audio
  • With a wide range of audio encoding technologies employed, the H850 allows you to experience the pleasure of pure audio.
Embedded Operating System
  • The H850 adopts a box design and an embedded operating system, facilitating installation and maintenance and helping prevent malicious attacks.
Safety
  • The H850 guarantees the safety and privacy of the meeting content using the 128-bit AES technique. Additionally, local login authorization and gateway password authentication are provided to enhance the meeting content safety.
Dual Stream
  • The H850 supports the H.239 protocol and the 1080p resolution for dual streaming.
Network Adaptability
  • The H850 is equipped with Intelligent Packet Loss Recovery, Dynamic Rate Adjustment and QoS optimization techniques. Based on various types of network environment, the system automatically adjusts its network transmission characteristics, to ensure crisp conference quality under adverse Internet network conditions.
  • By employing the  H.264 High-Profile technique, the H850 guarantees HD live viewing under low-bandwidth conditions. Moreover, the H850 supports NAT using an embedded proxy and supports IP-based data backup using two Ethernet ports.
