PCIe acquisition card is a hardware device based on PCI Express (Peripheral Component Interconnect Express, referred to as PCIe) interface standard, mainly used for high-speed data acquisition and transmission. This type of acquisition card is usually installed in the PCIe slot on the computer motherboard, and can capture ana-log or digital signals from various external devices or sensors, such as video streams (from cameras or other video sources), audio, sensor data, etc., and transmit these data to the computer system for processing, analysis or storage.
The advantage of PCIe acquisition card is its high data transfer rate and low latency, which is particularly important for applications that require real-time or near real-time processing of large amounts of data, such as high-definition video editing, machine vision, scientific experiments, medical imaging, industrial detection and other fields. Depending on the application requirements, they can provide different interface types, such as HDMI, SDI, Camera Link, LVDS, USB, etc., to connect different types of data sources.
