The term "camcorder" is derived from camera + recorder. It means a single unit which is both video camera and recording device.
Most people tend to think of a video camera and camcorder as being the same thing, but technically a camera is only the component which takes the light from the lens and converts it to an image. The recorder is a separate device, often known as a camera back. In professional camera/recorders, the camera and recorder are joined together and look like a single unit.
