If it is an option for you, consider using something like the LEADTOOLS Multimedia SDK:
https://www.leadtools.com/sdk/products/multimedia

Using this SDK, you can define a DirectShow Capture Control that uses your webcam's IP address as a source and record both images and video from your server machine.

By using multiple Capture Controls, you can perform capture of multiple camera.

For example, the code for 2 cameras would be like this:
CaptureCtrl1.VideoDevices.Selection = 0;
CaptureCtrl1.Preview = true;
CaptureCtrl2.VideoDevices.Selection = 1;
CaptureCtrl2.Preview = true;
For 2 IP cameras, the code looks like this:
PlayCtrl1.SourceFile = "udp://192.168.0.20"; //use camera's actual IP address
PlayCtrl2.SourceFile = "udp://192.168.0.21";
Then for each capture control, capture a still image from the camera as follows:
CaptureCtrl1.TargetFormat = TargetFormatType.StillImage;
CaptureCtrl1.StartCapture(CaptureMode.Still);
CaptureCtrl1.SaveStillBitmap("test.bmp", StillFormatType.BMP, 0, 0, -1);
If interested in this approach, you can download a free evaluation through the download manager from this page:
