To capture computer signals, you need to use a video capture card. Generally, VGA and HDMI are used to capture graphics cards. Among them, VGA capture cards are widely used. Mayfield M1200 VGA video capture card is a high-definition VGA video capture card with comprehensive functions, stable performance, and clear capture effects. The acquisition software and secondary development kit greatly meet the needs of various applications. As shown in the figure below, the exquisite workmanship and excellent performance continue to attract more users. The current promotional price of this capture card is 1500 yuan, and the price is good.
Research and development based on user needs has always been the pursuit of Miffy's products. In response to the need for simultaneous acquisition of multiple signals in the current video industry, this M1200 HD VGA capture card has innovatively added two video input interfaces. And can be collected at the same time. The two video interfaces adopt BNC interface, which can be connected to S terminal, AV video interface, etc. For example, in the remote teaching, the screen signal of the teaching computer can be collected with high quality through VGA, and the teacher's picture and the student's picture can be collected through the video interface. Such a M1200 high-definition VGA capture card solves all needs. What's more important is that this high-definition full-featured capture card also supports one machine with multiple cards, which can be used together with other streaming media capture cards to meet the multi-channel capture needs of various users.
