What is the difference between USB video capture card and graphics card?
Difference: The video capture card is used to input video information into the computer, while the graphics card outputs the video signals from the computer to other specific devices. One is the video signal "receiving" device, and the other is the display network signal "output" device. The video capture card is mainly used in industrial production and commercial activities. The graphics card is the basic device on the computer and is necessary. Some machinery and equipment.
Also known as video capture usb card, AHD capture card is one of them. It can be used to obtain intelligent video information, convert simulated analog video signals into analog signals for computer processing and use, and store and play hard-reduced video capture. Card out. Many video capture cards can obtain audio while capturing video information, so that the audio part and the video part can be stored and played simultaneously in an intelligent manner.

2. Independent graphics card
When connected to the notebook motherboard, it converts the analog signals on the computer into digital signals for display on the screen. At the same time, the independent graphics card still has image processing capabilities, which can help the CPU work and convert the graphics processed by the CPU into statistics. The GPU is then processed into image dot matrix output matching the display, improving the overall operating speed. Today's top computers all include independent graphics computing core. In scientific computing, independent graphics cards are called display accelerator cards.
The function of ultra-clear video capture card is to collect video signals into a computer and store them on a solid-state disk in the form of data files, which is especially used in the video surveillance system industry. In computer surveillance equipment, the solution is to output a digital signal through the camera, capture the video with a capture card, convert it into an analog signal, send it to the CPU for data processing, and then send the graphics card GPU to process the graphic data, and use the digital The analog conversion is given to the display screen through the VGA socket and finally converted into an image.
