Software solutions are available for controlling two USB-based webcams simultaneously from a single computer. Users can view both cameras at the same time and capture still images saved to a specific folder. One recommended tool for this purpose is VideoCapture, which allows for scripting to execute captures with custom filenames, alongside ImageMagick for image processing. Another option is using a TWAIN approach, which requires familiarity with the documentation for accessing multiple webcams. For those seeking surveillance software, a Google search may yield both shareware and freeware options, although some may need to develop their own solutions. Applications for using two webcams include creating stereo images for 3D effects or experimenting with machine vision, though the specific use case of the original inquiry remains unclear.
