Important Notes
⚠️ Disable In-Camera Stabilization
The gyroscope of the O4 Air Unit is extremely sensitive to vibrations from the drone body. If in-camera stabilization (such as RockSteady 3.0) is enabled, it may cause abnormal shaking or distortion in the footage due to vibration feedback overload, and only unstabilized video can be recorded.
⚠️ Upgrade to O4 Pro Unit
If you need to capture stabilized footage, it is recommended to upgrade to the O4 Pro Unit version.
The Explorer LR 4 O4 Pro Version can use RockSteady 3.0 and enhanced low-light performance.
