USB camera module is a kind of optical sensor module connected to the device through USB interface, its core function is to convert optical image into digital signal to realize image and video acquisition. It typically supports multiple resolutions and frame rates, and transmits data via a USB 2.0/3.0/Type-C interface, with plug-and-play and drive-free installation available on some models. High-end modules may integrate features such as autofocus, night vision, or wide dynamic range, and are compatible with multiple platforms such as Windows and Linux, and provide programming interfaces for developers to call. This type of module is widely used in video conferencing, security monitoring, industrial testing and other fields, the specific performance varies by model, users can choose the appropriate optical parameters and interface configuration according to actual needs.
According to the application scenario, it is mainly divided into the following categories:
Consumer-grade modules: mainly portable and compatible, commonly found in laptops or video conferencing equipment, support 1080p/30fps basic performance, suitable for live streaming, online classes and other scenarios;
Industrial-grade modules: with high-resolution sensors (such as 4K) and all-glass lenses, designed to resist electromagnetic interference, suitable for precision inspection, robotic vision or medical equipment;
Security grade module: Integrated infrared night vision, Wide Dynamic (WDR) and waterproof housing, supports motion detection algorithms and is designed for indoor and outdoor monitoring.
