Lowest Latency |
With DJI Goggles 3 and pick racing mode:
With 1080p/100fps video transmission quality, the latency is as low as 15 ms.
With DJI Goggles N3 and pick racing mode:
With 1080p/100fps video transmission quality, the latency is as low as 19 ms.
With DJI Goggles 2 or Goggles Integra：
With 1080p/100fps video transmission quality, the video transmission latency is less than 30 ms. Latency data represents the minimum latency during the screen refresh process of DJI Goggles.Tested in an outdoor open environment without interference. The video transmission latency data varies with different devices.

Max Video Transmission Range |
With DJI Goggles 3/DJI Goggles N3:
15 km (FCC),8 km (CE),8 km (SRRC)
Measured in an unobstructed outdoor environment free of interference. The above data shows the farthest communication range under various standards . The actual maximum communication range during flight is limited by the flight endurance of the aircraft. Always pay attention to RTH reminders in the app during your flight.
