While these security cameras themselves were strictly for image processing, recording was possible at the point of display via videocassettes of various formats. These systems typically used CCTV, closed circuit television, to allow companies to monitor their surroundings. In 1980, the same camera technology that brought soap operas to televisions nationwide also helped protect businesses against fraud and theft. The first digital security cameras systems were used by the military for security and reconnaissance. As the successor to the camcorder, these cameras first recorded to optical disks and later to flash memory as time progressed. This innovation soon saw a flood of digital video cameras from familiar companies including Sony, JVC, and Panasonic. The first digital video camera to feature video compression was released in 1993 and was known as the Ampex DCT. This product which was the first of its kind, followed by similar digital camera products from Kodak, Casio, Sony, and others. Digital image capture would make the leap from professional photography to consumer level in 1994 with the Apple QuickTake. In 1991, Kodak released the first digital camera intended for professional use by photojournalists, followed by Nikon’s F-3, which included a 1.3-megapixel sensor. The Kodak company would bring the next innovations in digital camera technology by introducing a number of digital camera products in 1987 and the creation of the “Photo CD” in 1990. Even though it is credited with starting the digital camera revolution, the Mavica was not a “true” digital camera as we understand them today, since images were still stored magnetically. This camera utilized a rotating magnetic disc, which was 2 inches in diameter and could record up to 50 still frames for playback or printing. The transition from analog to digital video capture began in 1981 with the development of the Sony Mavica single-lens camera. This invention came later to consumer prominence in the 1980s via the video camcorder, a device that brought video recording into the mainstream. Two companies, JVC and Panasonic, introduced a great advancement in video recording when they developed the first self-contained large format video cassette tapes in the 1970s. However, figuring out how to contain the tape remained elusive throughout the mid-20th century because it held a higher volume of information. The obvious choice was magnetic tape, a technology that was already in use for sound recording. This system, which was created for broadcasting, became the standard in the television industry and remained in wide use until the 1980s.Ĭathode ray tubes were suitable for broadcast purposes, but the question of a medium for recording was a challenge. Early televisions produced mechanical video images, but by the 1930s, new all-electronic designs based on a cathode-ray video camera tube, including two prominent versions by engineers Philo Farnsworth and Vladimir Zsworykin, replaced the mechanical variations with electron scanning technology. A Scottish engineer named John Logie Baird contributed to this work with a variation of an older device known as a “Nipkow disk,” a mechanical device that breaks an image into “scanlines” using a rotating disc with holes cut into it. In the early 1900s, the first experiments in image transmission were completed. The video camera was initially developed for use in broadcast media. This is an electronic format that has historically been stored on various media such as magnetic tape, CCD chips and solid state flash memory. ![]() Modern cameras utilize video technology rather than film. Film cameras have a long and varied history dating back to the late 19th century. It is important to differentiate the video camera from a “movie” camera, which is a motion picture camera that utilizes photographic film to record images. However, when one stops to consider the history of this device’s development, one develops a new respect for the advances in the technology of motion photography. Whether on a smartphone, tablet, laptop, or other device, most of us carry video technology and seldom think about it. ![]() Today, the video camera is a tool that is so deeply woven into everyday life that it seems strange to find a person without one. ![]() The Video Camera – From Innovation to Ubiquity
