A video system is a chain, not a camera spec
Choose the receiving hardware and mission first. Then lock the aircraft camera, transmitter, firmware branch, voltage rail, physical mount, and cooling plan to it.

Choose the receiver path before the camera
A camera, VTX, goggles, firmware branch, voltage rail, and frame mount form one system. “Digital” and “5.8 GHz” are not compatibility standards.
Current O4 performance unit
O4 Air Unit Pro
- Receiver path
- DJI Goggles 3 or N3 with FPV Remote Controller 3; Goggles 2 or Integra with FPV Remote Controller 2; separate receivers can provide control
- Aircraft hardware
- O4 Pro camera and air unit
- Live view
- Up to 1080p/100fps in supported configurations; DJI publishes a 15 ms minimum racing-mode figure under lab conditions
- Onboard recording
- Up to 4K/120fps onboard
- Power input
- 7.4V to 26.4V
- Physical fit
- About 32 g including camera; 33.5 x 33.5 x 13 mm air unit; larger 1/1.3-inch sensor camera
- Firmware line
- Use current DJI support and a supported Betaflight or INAV integration. DJI lists Betaflight 4.3+ for O4.
Decision rule
Choose it when onboard image quality and recording modes justify the extra size, weight, cooling, and frame-specific camera mount.
Compatibility boundary
Published range and latency are controlled test figures, not practical flight permissions or field guarantees. VLOS, airspace, and RF conditions still control the operation.
Reviewed 2026-08-23. Manufacturer latency and range values are controlled test results, not a promise of practical field performance or legal operating distance. Confirm current firmware, supported receiving hardware, regional RF settings, and the exact product manual before purchase or update.
