First of all you have to understand a bit about my background. I have never worked with IP cameras before, but I will have to access multiple IP cameras simultaneously with OpenCV very soon. Apart from that, my network knowledge is not that much good.
Now the question. I know OpenCV can access IP cameras using its URL with the help of VideoCapture. There are number of questions in StackOverflow as well. But, the IP address is something that can be changed by time to time, it is dynamic. So even in a IP cam, the IP will change by time to time. So if this is the case, does this mean every time you try to access the cameras with OpenCV, you have to find the IP address of the camera manually and change the URL in OpenCV as well? I do not need to access the cameras via the internet, accessing locally is fine, via Wifi or network cables. How can I set a fixed IP address/ URL so the OpenCV code has nothing to change every time?
PS: I navigated through lot of websites (sites from more than 5 result pages of Google search) but the answers given are either too old or not that much convincing. So I decided to walk into OpenCV forum for the answer.
