Three in one image data control

50ការបញ្ជូនឥតខ្សែ KM (supporting longer distances)

4K high-definition image with low latency

ការបង្ហាប់វីដេអូ H265/H264

Rich interfaces

ការបញ្ជូនបន្តតាមតម្រូវការ

frequency hopping

រូបភាព, ទិន្នន័យ, and control in one: one-way image transmission channel; Bidirectional data transmission channel; Unidirectional remote control channel

50KM ultra long distance (for further distance requirements, please refer to the high-power 2W module) ការបញ្ជូនឥតខ្សែ: the ultimate connection efficiency brings ultra long distance transmission, with ground to air measurements reaching 20km over the line of sight interconnection; End-to-end devices are not constrained by wire control, maintaining high degrees of freedom and mobility in space and distance

4K រូបភាពនិយមន័យខ្ពស់ជាមួយនឹងភាពយឺតយ៉ាវទាប: Ultra high bandwidth and stream support can easily handle 4K resolution video data streams. The 200ms screen to screen low latency and delay jitter sensitivity control is good, meeting the real-time requirements of video data end-to-end

H265/H264 video compression – AES encryption

HDMI+Ethernet port HDML; HDMI + AV-HDMI; SDI + AV-HDMI

The implementation of an adaptive retransmission mechanism at the bottom layer not only greatly outperforms the retransmission mechanism at the application layer in terms of efficiency and latency, but also greatly improves the performance and user experience of the link in interference environments.
