inno U20CAM-9281M UVC Camera Software

Description

• UVC cameras comply with UVC protocol and work with web-camera applications out-of-box
• UVC Cameras support Windows, Linux, and macOS Compatible with UVC drivers

What is a UVC Camera

• UVC Camera is a camera with a USB interface that meets the standards set for the USB Video Class. This means that every UVC Camera is a USB camera, but not all USB cameras are UVC Cameras because they might adopt the USB interface without meeting the Video class requirements.
• Therefore, a major advantage of UVC cameras is their universal compatibility and flexibility. As they meet the video class standard, you can easily use them on different platforms with a USB port without handling the driver issue, like the Raspberry Pi or a smartphone. It also makes it easier for you to migrate your applications from one platform to another.
• At present, our UVC cameras support Windows, Linux, MAC, and Android systems, but do not support the iPhone system.
