常見問題解答 (常問問題)

1. Does this COFDM video transmitter support both HDMI and IP camera input?

是. 它支持 4K HDMI input and IP camera RTSP video streams via Ethernet.

2. Can I use an IP camera with any IP address?

The transmitter has a fixed IP (192.168.0.215).
Your IP camera must be set to the same network segment (例如, 192.168.0.xxx).

3. What IP camera protocols are supported?

This model supports 即時傳輸協定.
Example input format:
rtsp://username:password@IP:554/Streaming/Channels/101

4. How far is the wireless transmission range?

Range depends on environment, 天線, 和接收器.
With 5W output, typical performance:

• Vcan2131 接收者: 200–300 ms latency

• Vcan2095 接收者 (低延遲): 90–130 毫秒

Long-range transmission is supported even under NLOS conditions.

5. Does the cofdm wireless video transmitter support encryption?

是, full AES256 end-to-end encryption.

6. Can I transmit data together with the video?

是. 一個 one-way transparent UART channel allows telemetry or control data to pass through the COFDM link.

Two methods:

• 網頁使用者介面 在 http://192.168.0.215/

• 控制串口 using SconA/B/C configuration panels or PC tools

8. What video latency can I expect?

• H.264 low-latency mode: ~90–130 ms

• H.265 4K mode: ~200–350 ms
  (Camera self-latency not included)

9. Can the transmitter work on a drone?

是.
Its light weight (313G), 尺寸緊湊, and strong anti-interference performance make it ideal for UAV/robotic applications.

10. Which receivers are compatible?
