Box Camera

The box camera is, with the exception of the pin hole camera, a camera in its simplest form. The form of the classic box camera is no more than a cardboard or plastic box with a lens in one end and film at the other. A simple box camera has only a single element meniscus fixed focus lens and usually lacks control of aperture and shutter speeds. This makes them suitable for daylight photography of medium distance, static subjects only -- snapshots, essentially. During the type's commercial life span, box cameras with photographic flash, shutter and aperture adjustment were introduced, allowing indoor photos.

IR Camera

A thermographic camera or infrared camera is a device that forms an image using title="Infrared radiation">infrared radiation, similar to a common camera that forms an image using visible light. Instead of the 450–750 nanometer range of the visible light camera, infrared cameras operate in wavelengths as long as 14,000 nm (14 µm).

IP Camera

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. There are two kinds of IP cameras: Centralized IP cameras, which require a central Network Video Recorder (NVR) to handle the recording, video and alarm management.

Decentralized IP cameras, do not require a central Network Video Recorder(NVR), as the cameras have recording functionality built-in and can thus record directly to digital storage media, such asflash drives,hard disk drives or network attached storage.
