PoE PTZ Camera: A PoE (power over Ethernet) PTZ camera may be powered and connected to the internet with a single Ethernet cable, eliminating the need for additional wiring. Analog PTZ Camera: Analog pan-tilt-zoom cameras are used to record surveillance footage, which is then stored in a DVR. DVR functionality is essential for converting ...
A whip zoom (also referred to as a snap zoom or crash zoom) is a type of camera shot in which the camera zooms in or out quickly, [1] [2] allowing the viewer to focus on the subject. [3] Another use of the whip zoom is to enable the shot to be edited as a cut from a long shot to a close up, or vice versa.
A zoom lens is a system of camera lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens . A true zoom lens or optical zoom lens is a type of parfocal lens, one that maintains focus when its focal length changes. [1]
Schematic of a conventional and a periscope zoom lens A smartphone with a 5x optical zoom periscope lens camera, recognizable by the rectangular shape of its lens. A periscope lens, sometimes called a folded lens, is a mechanical assembly of lens elements that uses a prism or mirror to redirect the light through the lenses with a 90° angle to the optical axis, as in a periscope.
