Does the monitoring acquisition card determine the definition of the monitoring camera?

There are several reasons why you think the definition is different: 1 Maybe the sampling rate of the acquisition card is low; 2. It may be that the interface with composite equal loss is selected; The display mode of computer is different from that of TV. Compared with TV, the brightness of computer is relatively low, computer is suitable for displaying static state, and TV is suitable for displaying dynamic state. The color of TV is brighter. Of course, the acquisition card is also one of the influencing factors. Professional acquisition cards range from thousands to hundreds of thousands or even millions.
