I. Product Overview: Professional Network Video Surveillance Decoding Solution

Qtenboard Network Decoder is a high-performance audio and video decoding device specially designed for network video surveillance systems. Developed based on professional decoding chips and the Linux operating system, it features excellent device stability and strong decoding capability.

Among them, H.265 series products support 4K ultra-high-definition decoding output, while H.264 series products support 1080P and lower resolution decoding. It is compatible with multiple network transmission protocols and bitstream transmission methods, providing strong support for core scenarios such as network audio and video decoding output, large-scale video wall decoding, and split-screen output on video walls.

It is widely used in places with high requirements for video decoding, such as security monitoring centers, command and dispatch rooms, and large exhibition halls.

II. Core Product Features: Flexible Expansion, Efficient Adaptation

1. Modular Structure Design, Combined on Demand

The device adopts a fully modular design, and multiple functional modules can be flexibly assembled according to actual needs. Each single module is equipped with 1 HDMI 2.0 output interface as standard, and an optional HDMI encoding input module is also available to realize the two-way function of "decoding + encoding", adapting to signal processing needs in different scenarios.

2. Multiple Chassis Specifications to Meet Different Scale Needs

It supports multiple standard rack-mounted chassis sizes including 1U/2U/4U/8U/12U/16U (12U/16U can be customized). The number of assembled modules can be flexibly adjusted according to the chassis specifications, and it also supports multi-machine cascading expansion, easily meeting the needs of different scenarios from small-scale monitoring to large-scale video wall systems:

3. Rich Interfaces, Compatible with Multiple Devices

It is equipped with a standard RS485 interface, which can connect to various analog devices (such as pan-tilts, controllers, etc.); 2 USB interfaces (for function expansion, not supporting matrix control); and a 10/100/1000Mbps adaptive network port to ensure stable transmission of network signals, easily connecting to IP cameras, NVR/DVR and other devices in the monitoring system.
