Introduction
Customers who evaluate the SF-C1019USB-D3.1-PLUS usually care about more than model number and price. They want to know whether a 3.1mm camera head can fit their device, whether 1MP image detail is enough, whether the module needs external lighting, whether it can support their working distance, and whether the cable and board layout will create redesign problems later.
This FAQ answers the most common buyer questions about the SF-C1019USB-D3.1-PLUS bare USB endoscope camera module.
1. What is the SF-C1019USB-D3.1-PLUS?
The SF-C1019USB-D3.1-PLUS is a 3.1mm separate-type bare USB endoscope camera module using the OV9734 1MP sensor. It supports YUV / MJPEG output at 1280×720@30fps and is designed for compact OEM visualization device integration.
2. What type of customer is this module suitable for?
It is suitable for OEM customers developing compact medical visualization devices, dental or oral inspection tools, veterinary endoscopes, industrial inspection tools, compact borescopes and custom endoscope devices.
It is especially suitable for customers who need a compact camera core rather than a finished endoscope product.
3. Is this a finished endoscope camera?
No. This is a bare endoscope camera module.
Customers need to design or evaluate the final housing, lighting, cable routing, sealing, connector protection and complete device structure according to their product requirements.
4. What is the camera head diameter?
The camera head diameter is D3.1.
This makes it suitable for compact devices that need a smaller probe than larger 5mm, 6mm or 8mm modules, while still requiring better image detail than many lower-resolution ultra-small modules.
5. What sensor does it use?
It uses the OV9734 sensor.
This sensor platform supports 1MP-class imaging and 1280×720@30fps output, making it suitable for basic HD-level visual feedback in compact endoscope applications.
6. What is the output resolution?
The module supports 1280×720@30fps output.
For many compact visualization devices, this provides clearer observation than 0.16MP or 0.5MP modules. However, it is not the same as 1080P, 5MP or 12MP high-resolution imaging.
7. Is 1MP enough for my project?
It depends on what the user needs to see.
1MP may be enough for structure observation, cavity inspection, alignment checking, general visualization and device guidance. It may not be enough for fine defect analysis, measurement, AI recognition or documentation-grade imaging.
8. Does this model have built-in LEDs?
According to the catalog, the standard configuration has no LEDs.
This is important for customers to understand. If the final device needs illumination, the customer should evaluate external lighting, device-level LED design or another module with built-in LEDs.
9. Why would a customer choose a no-LED bare module?
Some OEM customers prefer to design the lighting system themselves.
Built-in LEDs may create reflection, heat, uneven lighting or mechanical conflicts in some device structures. A no-LED bare module gives the customer more flexibility to design illumination based on the final product.
10. Does this module support LED dimming?
The catalog marks dimming as optional.
Because the standard module does not include LEDs, dimming requirements should be discussed according to the customer's actual lighting design and project structure. Customers should not assume a standard dimming function without project confirmation.
11. What is the field of view?
The module supports 100° / 120° FOV options.
A wider FOV helps users see more surrounding context in a narrow space. A slightly narrower option may be more suitable when the target area needs more focused observation.
12. Which FOV should I choose: 100° or 120°?
Choose based on working distance and target size.
If the user needs to see more surrounding area at close distance, 120° may be more suitable. If the user wants a slightly more focused view, 100° may be better. Sample testing is recommended before final confirmation.
13. What is the focusing range?
The module supports 5–100mm or 10–100mm focusing range options.
Customers should test the module at the actual working distance of their device. Choosing the wrong focus range can make the image look unclear even if the sensor and resolution are suitable.
14. Does it use a glass lens?
Yes. The module uses a glass lens.
For OEM customers, this can be useful when optical stability and image consistency are important during product evaluation.
15. Does this model support IP67?
The catalog does not mark this model as IP67.
Customers who need waterproof performance should not treat this bare module as a finished waterproof probe. Waterproof or sealing design should be evaluated at the complete device level or another IP67-supported module should be considered.
16. Can it be used in medical devices?
It can be evaluated as an imaging component for compact medical visualization device development.
Final medical compliance, safety validation, cleaning method, biocompatibility-related design and certification requirements must be evaluated according to the final device and target market.
17. Can it be used in industrial inspection tools?
Yes, it can be evaluated for compact industrial inspection tools, borescopes and narrow-cavity visual inspection devices.
Industrial customers should confirm lighting, working distance, protection structure and cable durability before selecting this model.
18. Is this module suitable for dental or oral inspection?
It may be evaluated for dental or oral inspection devices if the diameter, FOV, working distance and image detail match the product requirements.
If the application requires higher detail or specific lighting, customers should compare it with other module options.
19. Is this module suitable for veterinary devices?
Yes, it can be evaluated for compact veterinary observation devices.
The final choice should depend on probe size, target animal application, working distance, lighting method and device structure.
20. Is this module suitable for pipe inspection?
It can be evaluated for small pipe or narrow-cavity inspection if the device provides suitable lighting and mechanical protection.
If the environment is wet, dirty or rough, customers should carefully evaluate waterproof housing, protection structure and cable durability.
21. What is the standard cable length?
The standard cable length is 1.5m.
This should be checked against the final device structure, especially if the module will be installed in a long probe or handheld inspection tool.
22. What is the maximum cable length?
The catalog lists the maximum cable length as 4m.
Customers should test signal stability and image performance under the actual cable length and device layout.
23. What is the main board size?
The main board size is 33×13.5mm.
This compact board size is useful for OEM devices, but customers still need to confirm available internal space before finalizing the design.
24. 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 fits their assembly process, mechanical structure and host system.
25. Can this module work directly with a computer?
It is a USB camera module, but actual compatibility depends on the host system, driver support, software environment and connection design. Customers should test it with their own host device during sample evaluation.
26. Is this module suitable for plug-and-play consumer products?
Not directly.
This is a bare OEM module. Customers who want a finished consumer endoscope should choose a complete device or a more finished module structure.
27. What should customers test first after receiving samples?
Customers should test:
Image clarity at actual working distance
FOV in the final use environment
Lighting method
Cable routing
Board placement
Host compatibility
Mechanical protection
Long cable performance if required
Final housing or sealing concept
28. What is the most common mistake when choosing this module?
The most common mistake is choosing it only because it is 3.1mm and 1MP.
Customers should also check whether they need LEDs, waterproof design, specific FOV, longer cable, certain focus range and enough space for the board.
29. Can SincereFull customize this module?
Project-level customization or alternative module evaluation can be discussed based on diameter, lens, FOV, cable, connector, lighting and mechanical structure requirements.
Any change affecting optical performance, interface stability, waterproof design or production feasibility should be reviewed before confirmation.
30. How should I decide whether this is the right model?
Choose the SF-C1019USB-D3.1-PLUS if your project needs a compact 3.1mm bare USB imaging core, OV9734 1MP output, glass lens, wide FOV options and custom device-level integration.
Choose another model if your project needs built-in LEDs, IP67 waterproof probe design, higher resolution, stronger lighting, finished device structure or long-distance viewing.
31. What information should I provide before asking for a quotation?
Please provide:
