DJI O3 Air Unit video link phones home to Chinese servers but no Western alternative matches its latency

The DJI O3 Air Unit dominates FPV video transmission with sub-30ms latency at 1080p, but its firmware contacts DJI servers in Shenzhen on every boot and transmits telemetry including GPS coordinates. For military FPV operations, this creates an operational security nightmare where flight locations are potentially visible to Chinese intelligence. The only NDAA-compliant alternative (HDZero) has 720p resolution and 40-60ms latency with half the range. This persists because DJI invested $100M+ in custom OFDM silicon and codec optimization that no Western startup can replicate without comparable R&D spend, and the FPV market is too small to attract semiconductor investment from US defense primes.
