Videocam → It is formed from "video" (from Latin "videre", meaning to see) and "cam" (short for camera, from Latin "camera", meaning chamber or room). The word "videocam" refers to a device that allows you to see and capture moving images, essentially a camera that records video.
Think of 'seeing' ('videre') through a 'chamber' ('camera') — that's how a videocam lets you see and record moving images.
