The software capable of doing this would be a DVR system but it implies having compatible camera devices which in this case won't work. A DVR system is a device which provides instant feeds from the connected cameras but it costs something so I will provide a free solution which in this case would be iSpy because it lets you connect multiple webcams, microphones and so on. Simply download the application, install it and connect your webcams. Make sure the devices have their drivers installed before doing this operation. Use the wizard and add your webcams and start taking shots.
