Wig-wag (sound Stage)
A wig-wag (also wigwag, wig wag) is the red light (also known as a "red-eye") near each door of a motion picture sound stage. It flashes to indicate that cameras are rolling inside the stage and no one should enter or exit the stage for any reason, and all people and vehicles outside should remain quiet. A flashing wig-wag is accompanied by one long buzzer A buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric (''piezo'' for short). Typical uses of buzzers and beepers include alarm devices, timers, train and confirmation of user input such as a ... when the cameras start rolling, and two shorter buzzers when cameras stop rolling.

Sound Stage
A sound stage (also written soundstage) is a soundproof, large structure, building, or room with large doors and high ceilings, used for the production of theatrical film-making and television productions, usually located on a secured movie or television studio property. Compared to a silent stage, a sound stage is sound-proofed so that sound can be recorded along with the images. The recordings are known as ''production sound''. A silent stage is not soundproofed and is susceptible to outside noise interference; therefore, sound is not generally recorded. Because most sound in movies, other than dialogue, is added in post-production, this generally means that the main difference between the two is that sound stages are used for dialogue scenes, but silent stages are not. An alternative to production sound is to record additional dialogue during post-production (known as dubbing). Early history Structures of this type were in use in the motion picture industry before the adv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camera
A camera is an Optics, optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a Image sensor, digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A Shutter (photography), shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera dom ...

Buzzer
A buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric (''piezo'' for short). Typical uses of buzzers and beepers include alarm devices, timers, train and confirmation of user input such as a mouse click or keystroke. History Electromechanical The electric buzzer was invented in 1831 by Joseph Henry. They were mainly used in early doorbells until they were phased out in the early 1930s in favor of musical chimes, which had a softer tone. Piezoelectric Piezoelectric buzzers, or piezo buzzers, as they are sometimes called, were invented by Japanese manufacturers and fitted into a wide array of products during the 1970s to 1980s. This advancement mainly came about because of cooperative efforts by Japanese manufacturing companies. In 1951, they established the Barium Titanate Application Research Committee, which allowed the companies to be "competitively cooperative" and bring about several piezoelectric innovations and ...
