USB Video Capture Device

edit savecancel

Hi everyone,

I am looking into OpenCV for creating a graphical user interface overlay on top of a real time video feed. Before diving too much deeper, I wanted to make sure that OpenCV would satisfy my needs. From what I can tell, OpenCV is perfectly suited for overlaying transparent graphical elements over a video feed. However, unlike most people using OpenCV, I was hoping to use a composite RCA security camera rather than a webcam. Is this something that is possible? I was looking into a USB video capture device for interfacing the video with the pc (http://www.amazon.com/EasyCAP-DC60-Creator-Capture-High-quality/dp/B002H3BSCM/ref=sr_1_41?ie=UTF8&qid=1352483083&sr=8-41&keywords=digital+video+converter+usb). Thanks in advance,

Scott
