Can USB2.0 interface stably transmit 4K@30fps? This module provides an engineering-validated solution. Through hardware MJPEG compression and deep optimization of the UVC protocol stack, it achieves smooth 30fps output at 3840×2160 resolution within 480Mbps bandwidth, with latency controlled under 100ms-meeting fundamental requirements for real-time monitoring and vision analytics.
At its core is the Sony STARVIS IMX415 1/2.7" back-illuminated sensor with 1.45μm pixel size, delivering starlight-level low-light performance (0.01lux). Compared to conventional IR illumination, STARVIS technology outputs full-color images in microlight environments while preserving color information-practically significant for AI algorithms like facial recognition and object classification that rely on color features, avoiding additional latency from ISP false-color post-processing.
Optically, the 120° wide-angle lens is precisely matched to the sensor's optical axis through AA (Active Alignment) processing, achieving TV distortion <0.3% and eliminating mechanical focusing within a 6cm to 200cm working distance. This fixed-focus design essentially trades flexibility for mass-production consistency and long-term stability-an appropriate technical compromise for fixed-scenario applications like security surveillance and industrial AOI.
Manufacturing employs full-board SMT processes with 6-axis AA calibration equipment, ensuring lens-to-sensor planarity error <15μm. The module has passed four certifications (RoHS, CE, FCC, REACH), operates from -20℃ to 70℃, and achieves MTBF >50,000 hours-meeting industrial-grade 7×24 deployment requirements.
For cross-platform compatibility, the standard UVC1.0 protocol eliminates proprietary driver needs. verified adaptation includes ARM Linux (V4L2), Windows DirectShow, and Android Camera2 API, with OpenCV/Python calling examples provided-significantly lowering embedded integration barriers.
Target applications are clearly defined: cost-sensitive volume projects requiring Sony sensor quality, such as desktop industrial inspection, SMB security surveillance, education recording equipment, and UAV image transmission. By simplifying the interface and employing fixed-focus design while maintaining core imaging performance, the module controls BOM cost within a reasonable range-an engineered solution balancing performance and budget.
