VDC-48 Pro FDD+TDD Bi-directional Video/Data Transmission System

The VDC-48 Pro is a self-developed TDD bi-directional video/data transmission system with a maximum transmission distance of 48KM that utilizes both uplink and downlink FDD methods for wireless transmission. The product features real-time interference detection, adaptive frequency selection, adaptive bit rate, automatic retransmission, and automatic power control. These functionalities significantly enhance its multipath and interference resistance, making it highly reliable, stable, and low-latency. It is ideal for applications such as inspection, and monitoring.

Feature：
Asymmetric Transmission: Utilizes TDD+FDD for communication transmission.
