When sourcing Linux-based video cameras, prioritize UVC (USB Video Class) compliance, which ensures 'plug-and-play' functionality without proprietary drivers. Key specs include sensor type (e.g., Sony IMX series) for low-light performance, H.264/H.265 hardware encoding to reduce CPU load on the Linux host, and frame rates (minimum 30fps at 1080p). For industrial applications, ensure the camera supports V4L2 (Video4Linux2) drivers for seamless integration with OpenCV or ROS (Robot Operating System).
