Video cameras are devices used to capture moving images and sound. They can be found in various forms, including handheld camcorders, professional cameras, and even smartphones. Video cameras work by recording light through a lens onto a sensor, which converts the light into electronic signals. These signals are then processed and stored as video files. Modern video cameras often come with features like zoom lenses, image stabilization, and high-definition recording. They are widely used in different fields, such as filmmaking, television production, and surveillance. With advancements in technology, many video cameras now offer wireless connectivity for easy sharing and streaming of content.
