Warnings & recommendations
Information: Camera capture-cadence compatibility has not been verified for this mode.
Information: Area-only mode assumes a square site — photo counts and flight-time estimates may differ for long or irregular shapes.
Information: Shutter type is unknown for this camera mode — rolling-shutter distortion cannot be assessed.
Information: Check local drone regulations and airspace rules for altitude limits and permissions before flying.
