A higher camera frame rate is not always better. The choice of frame rate requires a trade-off between dynamic detail, data volume, lighting conditions, power consumption, and cost to select a camera with an appropriate frame rate. First, What Is Frame Rate? Frame rate refers to the number of image frames a camera can capture and output per second, measured in fps (frames per second). Simply put, the higher the frame rate, the more images are recorded per unit of time, resulting in higher temporal resolution and richer dynamic details. Conversely, a lower frame rate may cause the footage to appear choppy or laggy. Frame rate not only determines the smoothness of video but also directly impacts shooting results and data processing efficiency. The human eye generally perceives video at 24–30 fps as “smooth,” but this is only the minimum requirement for visual perception. In professional imaging and machine vision, frame rate selection often far exceeds this range, from a few frames per second to thousands of frames per second, to meet the demands of different scenarios for temporal precision. High frame rates provide a better visual experience but also introduce greater data processing demands and storage pressure. High Frame…

Short-wave infrared (SWIR) cameras can capture light in the 400–1700 nm band, a spectral range invisible to the human eye. Unlike visible-light cameras, SWIR cameras can penetrate haze, dust, and certain materials, enabling precise imaging in harsh environments. These cameras are widely used in industries such as industrial manufacturing, scientific research, agriculture, and security. Main Applications of SWIR Cameras 1. Industrial Inspection SWIR cameras are ideal tools for quality control in manufacturing environments: 2. Food and Agriculture SWIR imaging can distinguish subtle differences in organic materials: 3.
