The DV Captiva is a USB HD Video and VGA Capture device. It permits you to connect cameras, audio, and computers to a PC or Mac for live video streaming or capture. It includes HDMI, VGA, DVI, and composite inputs. Great for HD mobile webcasting. Captiva is powered from the USB 3.0 interface directly without connecting to heavy power adapters, making it very easy to carry. You can do a live dual-channel video shoot with equipment you carry in just a briefcase. This one device replaces the USB 2.0 or PCIe cards you need for video + VGA capture, a common requirement for webcasting seminars, meetings, and events. Choose the dual HD model to bring in two HD inputs, or choose the HD + SD model to bring in conventional SD video plus VGA/DVI. In either case, Captiva auto-detects the VGA mode, and you can even switch resolutions without restarting the system.
