Product features:
Standard protocol, integration and interoperability
Supports standard SIP and H.323 protocols, compatible with mainstream industry standard terminals and network side devices.
Low bandwidth, high definition
Supports the latest H.264 HP encoding standard, saving approximately 50% bandwidth compared to the previous generation compression standard.
Multiple microphone access methods
Supports three audio input solutions: digital microphone, USB microphone, and analog microphone, suitable for different conference scenarios and meeting more audio needs.
• Ultra high network security
Support H.460 firewall traversal technology to solve secure connections between public and private networks. Supports encryption algorithms such as H.235, SRTP protocol, and AES-128 to ensure comprehensive communication security.
1080P Full HD
1080P full HD support, supporting multi-channel (HDMI+DVI-I: HDMI, VGA) high-definition video input, and 2-channel (HDMI) high-definition video output.
Embedded DSP solution
Embedded DSP hardware solution, high efficiency, low latency.
• Fully open API
Fully open API, supporting the development of third-party applications, making it easy for customers to achieve customized needs through secondary development.
• Built in high-definition MCU function (optional)
Optional built-in MCU, can support up to 1+3 high-definition video conferencing, which is very suitable for the low-cost and simple maintenance needs of small and medium-sized enterprises for video conferencing.
• Infrared transmission
The terminal supports receiving infrared signals through a serial port. When working with a specified model of camera, it can receive infrared remote control signals through the camera. Even if the conference terminal is hidden in the backend, it can meet the control of all terminals.
Remote and local recording
Support remote recording function, only one PC is needed to achieve conference recording function. Supports USB storage for recording, plug and play, ensuring secure and confidential meeting records.
• Support bilingual voice simultaneous interpreting
The terminal not only supports simultaneous input of two different languages of sound, but also supports flexible mixing and encoding of two different languages of sound.
Super strong packet loss resistance, effectively solving the problems of network jitter and packet loss
In the case of severe network packet loss, FEC proprietary technology can be enabled. If the packet loss is less than 20%, it will not affect the system, and if the packet loss is 25%, the conference can still proceed normally.
