PCI-Express frame grabbers are available with a number of different video inputs. Some models are available for low profile PC cases. The frame grabbers are for applications in which analog video signals (PAL, CCIR, NTSC, RS-170) need to be processed by a PC. In addition to cameras, such video input devices include ultrasound and X-ray machines. Analog cameras are not only used in legacy applications; often they are preferred for price sensitive projects in which long cables are required. The frame grabbers have drivers for Windows, the SDK IC Imaging Control and the end-user application software IC Capture. The latter allows the setting of all frame grabber parameters, the display of live video stream and the acquisition of singular images and sequences.
