is there any possible script for c# to control multi camera

If you have cameras connected to your PC either directly (such as USB connection with DirectShow driver) or through a network (IP cameras), you can use LEADTOOLS Capture controls or Play controls to display video from these cameras.

For DirectShow cameras, 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";
