A digital video recorder is a combination of a video camera and a recorder that relies on digital technology for image and sound capturing. It has become common practice to refer to the device as camcorder only. One technical peculiarity that makes a digital video camcorder is the data storage device; there could be a memory card, a flash drive or a built-in hard disk drive. All these types of equipment can be used in hybrid models.
A modern digital video camcorder captures the image by focusing the light on the imager (sensor), and incidental light then gets transformed into an electrical signal. The digital video results from this electrical signal that becomes storable. A digital video carmcoder can be analyzed by each of its components. Depending on the user’s needs, optical control is achieved either automatically or manually.
From the iris or the aperture you regulate the light exposure, while with the zoom you control the angle of view and the focal length. The neutral density filter is one other feature available with a digital video camcorder. The functions are automatic, but many professionals choose to operate the optical functions manually.
The sensor or imager in the structure of modern digital video camcorder models is considered superior to the other methods of image capturing by the possibility of displaying colors better. The images are clearer with lower light capability. Yet, the most important and advantageous part of a digital video camcorder is the storage capacity. There is no fading, color change or color bleeding in the use of the digital devices, which makes the digital video camcorder superior to any analog device.
As for technical performance, statistics indicate that the Betacam so far offers the best digital formats for the editing of materials. Moreover, with digital connections, there are no bandwidth problems or the noise that usually affect analog recordings. Plus, time does not affect the quality of the stored materials. Yet, should a technical problem occur, the loss of archives is usually complete with any camcorder digital video.
