Questions Customers Care About Most
Q: Face recognition has high resolution requirements; is 4MP enough?
A: Absolutely enough. With 2560×1440 resolution, at a recognition distance of 1~3 meters the face pixel density far exceeds the requirements of recognition algorithms, and the recognition rate can reach over 99%.
Q: Can it recognize at night without a fill light?
A: Yes. With the 0.01lux starlight sensor and the F1.2 large aperture, clear imaging is achieved even under moonlight/streetlight conditions, with no additional fill light required.
Q: Is development difficult? Is a dedicated driver required?
A: No. With the standard UVC protocol, Windows/Linux/Android all have native support, and frameworks such as OpenCV/DirectShow can call it directly.

Core Pain Points and Solutions
| Pain Point | How this module solves it |
|---|---|
| The device appearance must be clean and the camera must not be obtrusive | 32×32mm ultra-small, can be hidden behind the device panel |
| QR codes on phone screens must be recognized and focusing must be fast | Fixed-focus lens, depth of field covering 30cm~∞, fast and clear QR scanning |
| Devices run 7×24h and must not crash | Industrial-grade stability, no failures in long-term operation |
| Power consumption must be low to avoid affecting device heat dissipation | 2W ultra-low power, almost no additional heat dissipation burden |
| Users of different heights must be accommodated | Optional wide-angle lens (2.8mm), covering a larger viewing angle |
Questions Customers Care About Most
Q: Is QR code recognition fast?
A: Yes. With a smooth 25FPS frame rate and hardware H.265 encoding, the latency from capture to recognition is <100ms, giving a smooth scanning experience.
Q: Can it recognize QR codes on phone screens?
A: Yes. With the fixed-focus lens design, 30cm~∞ is clearly imaged, and QR codes on phone screens are easily recognized.
Q: Will device heating affect the camera?
A: No. The module itself consumes only 2W and generates very little heat; it also supports a 0~70℃ wide temperature range, adapting to the internal environment of the device.
Scenario 3: Robot and Drone Vision

| Fast integration is needed to shorten the R&D cycle | UVC driver-free, directly called by ROS/OpenCV |
Questions Customers Care About Most
Q: How well does it work for visual SLAM?
A: Very well. The 4MP resolution provides rich detail and 25FPS ensures motion estimation accuracy; combined with an IMU, high-precision visual SLAM can be achieved.
Q: Will the picture shake or blur during drone flight?
A: No. The electronic shutter speed can reach 1/100,000 second, so the picture remains clear even under high-speed motion; electronic image stabilization is supported (algorithm support required).
Q: Is it compatible with development boards such as Raspberry Pi / Jetson?
A: Fully compatible. With the standard UVC protocol, it is directly supported by Linux V4L2, and the ROS/OpenCV/GStreamer frameworks adapt perfectly.

Questions Customers Care About Most
Q: Is the precision enough for defect detection?
A: Yes. At an appropriate object distance, 4MP can achieve micron-level detection precision, meeting the needs of most industrial inspection applications.
Q: Is it compatible with Halcon/VisionPro?
A: Yes. With the standard UVC/DirectShow interface, mainstream machine vision software can call it directly.
Q: Can an external trigger signal be connected?
A: The USB camera itself does not support hardware triggering, but capture can be triggered by software; the frame rate is stable at 25FPS, meeting the cycle time of most inspection tasks.
