A camera is a device thatrecords and stores images. These images may be still photographs or moving images such as videos or movies. The term camera comes from the word camera obscura (Latin for "dark chamber"), an early mechanism for projecting images. The modern camera evolved from the camera obscura.
Cameras may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A camera generally consists of an enclosed hollow with an opening (aperture) at one end for light to enter, and a recording or viewing surface for capturing the light at the other end.
A majority of cameras have alens positioned in front of the cameras opening to gather the incoming light and focusall or part of the image on the recording surface. The diameter of the aperture is often controlled by a diaphragm mechanism, but some cameras have a fixed- size aperture. Most 20th century cameras used photographic film as a recording surface, while themajority of new ones now use an electronic image sensor.
The still camera takes one photo each time the user presses the shutter button. A typical movie camera continuously takes 24 film frames per second as long as the user holds down the shutter button, or until the shutter button is pressed a second time.

A camera phone is amobile phone which is able to capture still photographs (and usually video). Since early in the 21stcentury the majority of mobile phones in use are camera phones.
A digital camera (ordigicam) is a camera that takes video or still photographs, or both, digitally by recordingimages via an electronic image sensor. It is the main device used in the field of digitalphotography. Most 21st century cameras are digital.
A remote camera is a camera placed by a photographer in areas where the photographer generally cannot be. This includes areas with limited access, tight spaces where a person is not allowed, or just another angle so that the photographer can simultaneously take pictures of the same moment from different locations.
An Internet protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which unlike analog closed circuit television (CCTV) cameras can send and receive data via a computer network and the Internet. Although most cameras that do this are webcams, the term "IP camera" is usually applied only to those used for surveillance.
The movie camera is a type of photographic camera which takes a rapid sequence of photographs on strips of film which was very popular for private use in the last century until its successor, the video camera, replaced it.
A traffic camera is a video camera which observes vehicular traffic on a road.
HisA twin-lens reflexcamera (TLR) is a type of camera with two objective lenses of the same focal length. One of the lenses is the photographic objectiveor "taking lens" (the lens that takes the picture), while the other is used for the viewfindersystem, which is usually viewed from above at waist level.
A video camera is a camera used for electronic motion picture acquisition, initially developed bythe television industry but now common in other applications as well.
The first, characteristic of much early broadcasting, is live television, where the camera feeds real time images directly to a screen for immediate observation. A few cameras still serve live television production, but most live connections are for security, military/tactical, and industrial operations where surreptitious or remote viewing is required. In the second mode the images are recorded to a storage device for archiving or further processing; for many years, videotape was the primary format used for this purpose, but optical disc media, hard disk, and flash memory in tapeless camcorders are all increasingly used.
The view camera is a type of camera first developed in the era of the Daguerreotypeand still in use today, though with many refinements.Itcomprises a flexible bellows which forms a light-tight seal between twoadjustable standards, one of which holds a lens, and the other a viewfinder or a photographic film holder.
