Introduction
Customers evaluating the SF-C1019USB-1000P-D3.9-PRO usually care about practical questions: Is 1000×1000@60fps useful for our device? Is fixed LED brightness enough? Does IP67 meet our environment? Which FOV should we choose? Which focus range is suitable? Can the cable and board fit our product?
This FAQ answers the most common buyer questions before sample testing and OEM project evaluation.
1. What is the SF-C1019USB-1000P-D3.9-PRO?
The SF-C1019USB-1000P-D3.9-PRO is a D3.9 USB endoscope camera module using the ES101 sensor. It supports YUV / MJPEG output at 1000×1000@60fps, includes 4pcs 0402 LEDs and supports IP67.
2. What is the main value of this model?
Its main value is the combination of D3.9 compact size, 1000×1000 square-format output, 60fps smooth live video, built-in LEDs, IP67 support and flexible FOV / focus options.
3. What does 1000P mean for this product?
For this model, 1000P refers to 1000×1000 output.
This square-format image can be useful when the application needs balanced viewing around the camera center instead of a wide rectangular frame.
4. Why would customers choose 1000×1000 instead of 1280×720?
1000×1000 provides a more balanced square image.
This may be useful for cavity inspection, pipe-like spaces or applications where the user wants similar visibility in vertical and horizontal directions.
5. What is the frame rate?
The module supports 1000×1000@60fps.
The 60fps output can help provide smoother live video when the probe moves during operation.
6. Does 60fps mean better image quality?
Not directly.
60fps improves motion smoothness. Image quality also depends on lighting, lens, focus distance, FOV, software and final device structure.
7. What sensor does this module use?
This model uses the ES101 sensor.
It is positioned for 1000P-class compact endoscope visualization.
8. What is the camera head diameter?
The camera head diameter is D3.9.
This makes it suitable for compact endoscope devices where a small probe is needed but enough space is still required for LEDs and IP67-supported structure.
9. Does this module have built-in LEDs?
Yes. It includes 4pcs 0402 LEDs.
These LEDs provide local illumination for dark cavities and close-range inspection environments.
10. Can the LED brightness be adjusted?
No. This PRO version is the non-dimmable version.
If the project needs adjustable LED brightness, customers should discuss the PLUS version or another suitable model.
11. When is non-dimmable LED acceptable?
Fixed LED brightness may be acceptable when the working distance is stable, the target surface is not strongly reflective and the user does not need frequent brightness adjustment.
Customers should test the LED effect in the real environment before final confirmation.
12. When should I avoid the non-dimmable version?
Avoid the non-dimmable version if the target surface is wet, shiny, metallic or highly reflective, or if the working distance changes greatly during use.
In those cases, adjustable brightness may be important.
13. Does this module support IP67?
Yes. The catalog marks IP67 as Yes.
This makes the module suitable for applications that may involve moisture, cleaning, liquid exposure or harsh inspection environments.
14. Does IP67 mean the final device is automatically waterproof?
No.
Final waterproof performance depends on the complete device design, including housing, sealing, cable exit, connector protection, adhesive and assembly process.
15. Can this module be used in medical devices?
It can be evaluated as an imaging component for medical visualization device development.
Final medical compliance, cleaning validation, safety testing and certification should be handled according to the complete device and target market.
16. Can it be used in industrial inspection tools?
Yes. It can be evaluated for industrial borescopes, pipe inspection tools, cavity inspection devices, equipment maintenance tools and portable inspection systems.
Industrial customers should confirm IP67 requirements, lighting, cable durability and mechanical protection.
17. Is it suitable for dental or oral inspection?
It can be evaluated for dental or oral inspection devices if the D3.9 diameter, FOV, working distance and fixed LED brightness match the application.
If the target surface causes strong reflection, a dimmable option may be better.
18. Is it suitable for veterinary endoscope devices?
Yes, it can be evaluated for veterinary visualization tools.
The final choice depends on target application, working distance, brightness requirement, waterproof needs and device structure.
19. What FOV options are available?
The module supports 95°, 100°, 110°, 120° and 140° FOV options.
This allows customers to choose between focused viewing and wider cavity observation.
20. Which FOV should I choose?
Choose 95° or 100° when you need a more focused view.
Choose 110° or 120° for balanced viewing.
Choose 140° when the user needs a wider view inside a narrow cavity.
Final selection should be confirmed through sample testing.
21. What focusing range options are available?
The module supports 4–10mm, 5–50mm, 5–100mm and 10–100mm focusing range options.
This allows customers to match the module to different working distances.
22. Which focus range should I choose?
Choose 4–10mm for very close inspection.
Choose 5–50mm for general close-range observation.
Choose 5–100mm or 10–100mm when the target is farther from the camera head.
Customers should measure actual working distance before selecting samples.
23. What is the front length?
The front length is 12mm.
Customers should confirm whether this front-end length fits the probe or device structure.
24. What lens material options are available?
The catalog lists plastic / glass lens options.
Customers should choose based on optical performance, cost, durability and application requirements.
25. What is the standard cable length?
The standard cable length is 1m.
This should be checked against the customer's device layout and user operation distance.
26. What is the maximum cable length?
The maximum cable length listed in the catalog is 4m.
If customers need longer cable routing, signal stability and image performance should be tested in the final device structure.
27. What is the main board size?
The main board size is 40×13.5mm.
OEM customers should confirm whether this board can fit inside the device housing, handle or control unit.
28. What connector does it use?
The front connector is bonding wire, and the back connector is Micro USB.
Customers should confirm whether this connection method matches their assembly process and host system.
29. Is this a finished endoscope device?
No. It is an endoscope camera module for OEM integration.
Customers still need to evaluate housing, cable routing, mechanical protection, host compatibility and final device assembly.
30. Can it work directly with a computer?
It is a USB camera module, but actual compatibility depends on the host system, software, driver support and connection design.
Customers should test it with their intended host device before final confirmation.
31. Is this module suitable for AI inspection?
It is generally not the first choice for AI or measurement-level inspection.
For AI recognition, customers usually need controlled lighting, stable image conditions and sometimes higher resolution depending on the task.
32. What should customers test first after receiving samples?
Customers should test:
Image smoothness during movement
Fixed LED brightness in the real cavity
Reflection on target surfaces
Selected FOV at actual working distance
Focus clarity
IP67 performance after assembly
Cable length and signal stability
Board placement
Host compatibility
Mechanical fit of the D3.9 front end
33. What is the most common mistake when choosing this model?
The most common mistake is choosing it only because it supports 1000P and IP67.
Customers should also confirm whether fixed LED brightness is acceptable, whether the FOV matches the scene, whether the focus range matches the working distance, and whether the cable and board fit the final product.
34. How is the PRO version different from the PLUS version?
The catalog notes that the PRO version is the non-dimmable version of the PLUS model.
If LED brightness adjustment is important, customers should discuss whether the PLUS version or another module is more suitable.
35. Can SincereFull customize this module?
Project-level customization or alternative module evaluation can be discussed based on diameter, lens, FOV, focus range, lighting, cable, connector and mechanical structure requirements.
Any change affecting optical performance, waterproof design, signal stability or production feasibility should be reviewed before confirmation.
36. What information should I provide before requesting a quotation?
Please provide:
