Do digital cameras need acquisition cards?

Hello, SD card and CF card, CD-ROM drive and hard disk camera, you can collect the video of the output interface through the acquisition card, but you can also find the software editor directly without the acquisition card. Software generally needs to support your camera coding, but I personally think it is ok to copy it directly to the computer and find a better supported software. You don't need to spend money on cards. Of course, it depends on the specific needs of users.
