Q: Q1: What’s the range of COFDM 2W Long-Range Video Audio Transceiver?

A1: Typically 1–2 km near the ground, and up to 4–8 km in clear LOS conditions (depends on environment and antenna height).

Q: Q3: Can it support two-way data?

A: Yes. It supports bidirectional RS232/RS485 data and two-way voice intercom simultaneously.

Q: Q5: Why does video blur when moving fast?

A: It’s caused by dynamic video compression — a trade-off to maintain real-time low latency .
