SIYI A8 mini 4K Drone Gimbal Camera

A8 mini is a 95 g, three-axis visible-light camera for small UAV imaging projects. Its fixed lens keeps the camera compact, while recording modes give you a choice between a detailed wide view and digital enlargement. For FPV UAV builders adding a separate inspection camera, start with the footage you want to save and the video connection your aircraft already uses.

Choose the recording mode first

The headline 6× zoom belongs to the 720p mode. A8 mini does not combine 4K recording with 6× zoom, and it does not contain an optical-zoom lens. Select a mode according to the task rather than treating every setting as available at once.

SIYI A8 mini visible-light camera and three-axis gimbal
A8 mini is a compact visible-light payload with a fixed lens.

A compact visible-light payload

The camera has an 8 MP, 1/1.7-inch sensor and a fixed lens with a 21 mm equivalent focal length. It suits general site documentation, daylight roof inspection and operator-controlled viewing where thermal imaging is not part of the job.

Allow room for installation

The listed camera dimensions are 55 × 55 × 70 mm. Plan space for gimbal movement, the mount and cables as well as the camera body. Use 95 g as the camera mass, then add the mounting and wiring items chosen for your aircraft.

Connect viewing, control and storage separately

Ethernet, CVBS and micro-HDMI provide video connection choices. S.Bus, UART and Ethernet UDP/TCP provide control choices. Local recording uses a microSD card up to 256 GB, with MP4 video and JPG photographs. A camera recording in 4K still needs a compatible video link and ground display for live viewing; choose that path independently.

A8 mini selection questions

Can it record 4K while using 6× zoom?

No. The 4K mode has no zoom. The maximum 6× digital zoom is available in 720p mode.

Is A8 mini a thermal camera?

No. It is a single visible-light camera. Choose a dual-sensor gimbal when heat patterns are part of your inspection.

Does every photograph use the full sensor resolution?

The manual states that saved-photo resolution follows the selected video mode. Set the recording mode before planning your image deliverable.

Is AI tracking included?

AI tracking uses an optional module. Request the module and its connection items if that function is needed.

Send the details for your A8 mini kit
