Video camera
Optical instrument that captures video for live or recorded use.
A video camera is an optical instrument that captures videos, as opposed to a movie camera, which records images on film. Video cameras were initially developed for the television industry but have since become widely used for a variety of other purposes, including security, surveillance, scientific research, and consumer electronics.

Lore & Background
The earliest video cameras were based on the mechanical Nipkow disk and used in experimental broadcasts through the 1910s–1930s. All-electronic designs based on the video camera tube, such as Vladimir Zworykin's Iconoscope and Philo Farnsworth's image dissector, supplanted the Nipkow system by the 1930s. These remained in wide use until the 1980s, when cameras based on solid-state image sensors such as the charge-coupled device (CCD) and later CMOS active-pixel sensor eliminated common problems with tube technologies and made digital video workflow practical.
Reader's Guide
Video cameras have evolved from mechanical Nipkow disk systems to all-electronic tube cameras and then to solid-state digital sensors, fundamentally changing how visual information is captured and distributed. Initially developed for live television broadcasting, they now serve two primary modes: live feeds for immediate observation (used in security, military, and industrial operations) and recorded video for archiving or later analysis (used in television production, surveillance, and monitoring). The transition from analog to digital, driven by solid-state sensors and video compression standards, made digital video workflow practical and led to the widespread adoption of digital video cameras by the early 21st century. The distinction between professional video cameras and movie cameras has disappeared as the intermittent mechanism has become the same, with mid-range cameras used for television termed professional video cameras. Recording media evolved from early disc-based systems to videotape (Quadruplex, Betacam), then to optical disc, hard disk, and flash memory.
