2. SF-C1019USB-D3.9-PLUS: Wide-Angle & Long-Distance Design for Comprehensive Detection

  • Technical Features: 110° horizontal wide field of view, 10~100mm long focus range, PureCel® pixel technology, consistent reliable performance with the high frame rate version.
  • Typical Application Scenarios
  1. Large-area internal inspection: Wide field of view covers more areas, suitable for pipeline internal condition detection and building hidden part observation.
  2. Long-distance narrow space observation: 100mm maximum focus range enables clear imaging of distant targets in deep cavities.
  3. Automobile parts assembly inspection: Wide angle and long focus range help check the assembly status of internal components.
  4. Precision mold defect detection: High sensitivity sensor accurately identifies tiny cracks and defects in low-light environments.
  • Selection Recommendation: Choose this model when inspecting large-area scenes, requiring long-distance observation, or needing a wide field of view to avoid detection blind spots.


FAQ ◢

1. How does the endoscope camera module work?

The endoscope camera module collects the internal image through the front optical lens, converts it into electrical signal by CMOS or CCD sensor, and then optimizes it through image processing chip for noise reduction and enhancement, and finally outputs high-definition video signal. Some modules support wireless transmission or fiber optic signal transmission, suitable for medical or industrial inspection scenarios.


2. What is the main difference between the two models?

The core differences lie in frame rate, field of view and focus range: SF-C1011USB-D3.9-720P60 focuses on high frame rate (60FPS) for dynamic scenes, while SF-C1019USB-D3.9-PLUS features a wider field of view (110° horizontal) and longer focus range (10~100mm) for comprehensive coverage. Other parameters such as imaging quality, protection level and interface are completely consistent.


3. What does an "IP67" protection rating mean for these modules?

The IP67 rating indicates a high level of environmental protection. It is completely dust-tight (6) and can withstand immersion in water up to 1 meter deep for 30 minutes. This makes the modules suitable for use in dusty, humid, or wet conditions, such as inside pipes or containers.


4. Can the focal distance be adjusted after production?

The modules are designed with manual focus fixed during the manufacturing and assembly process to ensure stability and reliability. The focus range is preset (10mm~100mm for PLUS, 10mm~80mm for 720P60). Field adjustment by end-users is not recommended or supported.


5. Is custom OEM/ODM service available?

Yes, we provide professional OEM and ODM services. We can discuss custom requirements regarding cable length, specific lens characteristics (e.g., different FOV), housing design, and other parameters to tailor the solution to your specific application.


6. What is the standard length? Can it be extended to 5 meters?

The standard product is equipped with a 1meter shielding cable. By using a repeater amplifier chip, it can be extended to 5 meters, but this may affect signal integrity. It is recommended to use a high-quality USB 2.0 extension cable or switch to a coaxial transmission solution (customization required).
