The camera module industry stands at a crossroads. As devices grow smaller, smarter, and more interconnected, the demand for flexible, efficient power solutions has never been greater. For decades, camera modules relied on dedicated power cables or bulky adapters, limiting their integration in compact designs and edge applications. But a quiet revolution is underway: Power Over USB (PoE USB) is emerging as a transformative force, promising to redefine howcamera modulesare powered, deployed, and integrated across industries.
The Limitations of Traditional Camera Power Solutions
Traditional camera power systems suffer from three critical flaws that hinder innovation. First, dedicated power cables increase design complexity, especially in space-constrained devices like wearables or industrial sensors. Second, compatibility issues plague multi-vendor ecosystems—each manufacturer often develops proprietary power interfaces, creating fragmentation. Third, power inefficiency leads to shorter operational lifespans, a major pain point for battery-powered devices and remote monitoring systems.
Consider the automotive industry, where Advanced Driver Assistance Systems (ADAS) rely on multiple camera modules for lane departure warnings and blind-spot detection. Until recently, these cameras required separate power circuits, adding weight and manufacturing costs. The SNS Insider report projects the U.S. automotive USB power delivery system market will grow from 434.12 million in 2022 to 1442.9 million by 2030, a CAGR of 16.2% ¹. This surge reflects an industry-wide shift toward USB-powered solutions that eliminate redundant wiring while delivering reliable power.
In industrial settings, traditional camera modules face similar challenges.
