Open firmware OpenIPC made digital FPV affordable: HD picture, low latency and efficient H.265 on inexpensive hardware. How it works and where it’s used — from civilian tasks to reconnaissance and observation.

A weak FPV signal, noise and image dropouts usually come not from the receiver but from wrong antenna placement. Practical principles: a clear zone around the antenna, vertical polarization, height, the Fresnel zone, spacing from GPS on a UAV, and cooling.
