Introduction
SF8A824 is an 8MP USB 3.0 camera module developed for imaging devices where the target distance changes during normal use. The standard configuration uses VCM Autofocus, while a Fixed-Focus version can be evaluated for devices with a stable installation distance.
It uses a 1/2.5-inch IMX317 sensor with 1.62μm pixels and supports MJPG and YUY2 output through a USB 3.0 Type-C UVC interface. The standard 38 × 38mm PCB provides a square-board route for OEM equipment requiring 4K imaging and autofocus flexibility.
Applications in Real Devices
Variable-Distance Inspection Terminals
Inspection terminals may observe components positioned at different distances. VCM Autofocus allows the device to adjust focus without requiring a fixed mechanical target plane.
Smart Kiosks and Interactive Devices
Interactive devices may capture users, documents or objects placed at changing positions. The Autofocus route can be evaluated when one fixed optical setting cannot cover the complete operating range.
Document and Object-Capture Systems
The 8MP resolution and D88° optical direction can support devices that switch between document capture and general object imaging, subject to final lens and autofocus validation.
Project Evaluation Guide
Consider This Model When
- The target distance changes during device operation.
- VCM Autofocus is preferred as the standard optical route.
- The host requires USB 3.0 Type-C and UVC.
- MJPG 4K@30FPS meets the video requirement.
- A 38 × 38mm PCB fits the enclosure.
Confirm Before Sampling
- Autofocus target range and expected response.
- Whether standard AF or optional FF is required.
- Target FOV and minimum object distance.
- Host USB and UVC environment.
- PCB height, Type-C position and mounting points.
- Whether hardware trigger or microphone customization is required.
- SDK and development-interface requirements.
Choosing This Model Within the 4K USB Camera Module Series
SF8A824 occupies the standard Autofocus position within the square-board 4K USB Camera Module Series. It is relevant when variable working distance is more important than the highest available 4K frame rate.
Projects requiring Fixed Focus, HDR and 4K@60FPS may compare SF8A625-88. Projects needing a slimmer elongated PCB or a lower-distortion optical route may evaluate SF-OC2688-415-V1.0.

SincereFirst Customization
Lens and D88° FOV
The standard optical direction provides D88° coverage. Alternative focal lengths and FOVs can be evaluated according to the scene width, target distance and enclosure opening.
VCM Autofocus and Optional Fixed Focus
The standard configuration uses VCM Autofocus. A Fixed-Focus version can be evaluated when the device operates at a predictable target distance and does not require continuous focus adjustment.
PCB, Type-C and Optional Project Functions
The 38 × 38mm PCB, mounting points, lens height and Type-C connector position can be coordinated with the mechanical structure. Hardware trigger and microphone directions require separate project customization.
USB 3.0, UVC and SDK Integration
MJPG/YUY2 modes, UVC compatibility, autofocus control, SDK requirements and development interfaces can be reviewed with the target host and software environment.
Final configuration should be validated with the actual host platform, enclosure, optics, software, and lighting environment before sampling.
FAQ
Is Autofocus the standard configuration?
Yes. The standard version uses VCM Autofocus. Fixed Focus is available as an optional direction.
Does it support 4K video?
Yes. The specification lists MJPG 4K@30FPS and YUY2 4K@15FPS.
Are hardware trigger and microphone functions standard?
No. Both functions require project customization.
When should the Fixed-Focus version be selected?
Consider Fixed Focus when the target distance is stable and the device does not require autofocus control.
