Camera — a device for registering still images (taking photographs). The recording of an image in a camera is carried out by a photochemical method when light is applied to a photosensitive photographic material. The latent image obtained in this way is converted into a visible one during laboratory processing. In a digital camera, photographic recording occurs by photoelectric conversion of an optical image into an electrical signal, digital data about which is stored on a non-volatile medium.

Video is an electronic technology for the formation, recording, processing, transmission, storage and reproduction of a moving image based on the principles of television, as well as an audiovisual work recorded on a physical medium (videotape, videodisc, etc.).
