SF-C1019USB-D3.9-PRO OV9734 V1.2
SINCEREFIRST
The OV9734 3.9mm 720P USB Endoscope Camera Module with Steel Shell for compact direct-view inspection where mechanical protection matters. Its D95° field of view and 10–100mm focusing range cover a practical close-to-medium inspection window. Four 0402 LEDs illuminate nearby targets, while USB2.0 UVC with YUV/MJPEG output keeps the host-side integration straightforward. Difference: This 3.9mm version is built around protected direct-view inspection, not side-view observation or extreme miniaturization. |  |
Selection Requirement | Standard Configuration | Selection Note |
Entry Space | 3.9mm | Confirm the protected front end fits the opening. |
Target Direction | Direct view | Use when the target is mainly ahead of the insertion direction. |
Output | 720P@30fps | Suitable for routine HD real-time viewing. |
Working Distance | 10–100mm | Confirm the actual target falls in range. |
Coverage | D95° × H85° × V43.5° | Check target size and required coverage. |
Host | USB2.0 UVC | Verify host compatibility during sample integration. |
Product Advantage ◢
1. 3.9mm Steel-Shell Front End — adds mechanical protection without moving the product out of the compact inspection class.
2. 720P@30fps — gives the operator a stable HD live view for general inspection and positioning.
3. D95° Field of View — balances scene coverage with a more focused direct-view image than ultra-wide optics.
4. 10–100mm Focus Range — accommodates targets from close inspection to a more extended internal viewing distance.
5. Four 0402 LEDs — place illumination around the viewing axis for darker enclosed spaces.
This model fills the middle ground between ultra-small micro modules and larger inspection cameras. The 3.9mm steel-shell direction is useful when the device needs a compact protected front end but still requires 720P real-time output and a practical 10–100mm viewing range.

FAQ ◢
1: What type of camera module is SF-C1019USB-D3.9-PRO OV9734 V1.2?
It is a D3.9mm USB2.0 UVC Endoscope Camera Module with an OV9734 sensor direction, Steel Sleeve front-end structure, LED structure, and 720P Max 30fps output.
2: What is the benefit of the D3.9mm Diameter?
D3.9mm helps the camera head enter small openings, narrow tubes, compact cavities, and equipment gaps where larger endoscope heads may not fit.
3: What is the value of the Steel Sleeve structure?
The Steel Sleeve provides stronger front-end protection for insertion-type inspection and repeated handling. Waterproof performance should be confirmed separately.
4: Does this module support waterproof inspection?
Waterproof or IP67 protection is not specified. If wet-environment or sealed inspection is required, an IP-rated structure should be reviewed separately.
5: What output does this module support?
It supports USB2.0 UVC output with YUV & MJPEG format, up to 720P Max 30fps.
6: Is it suitable for high-detail defect analysis?
It is more suitable for real-time inspection and repair preview. For high-detail defect analysis, a 1080P, 5MP, or higher-resolution endoscope module should be reviewed.
7: Does it support adjustable brightness?
LED dimming is not specified. If adjustable brightness is required, a dimming-supported structure or customized LED control design should be evaluated.
8: What information should I provide to confirm whether this module fits my project?
Please share your target device, required Diameter, working distance, FOV requirement, cable length, connector type, lighting condition, protection requirement, host platform, and expected inspection application.
