Need to grab images using OpenCV

Hi, Guys, What is the best method to be able to grab images from 11 different ETHERNET cameras ? Is OPENCV a .dll that I can use to grab images from any IP camera ? How can I get licenso to use it ? I use C#.NET 2022 but I am a newbie in grabbing images. Can anyone give me any hint to how to move forward ? Thanks !! Antonio Fasano - Brazil

no, it is a c++ library (and there are no no c# bindings builtin, you have to do that on your own or fall back to 3rd party things like opencvsharp)
(but again, yes, you can grab images from ip cams with it !)

apache2 license, it’s free.

again, we don’t really care about .net here
