1.2.2 Camera Types
Generally, network cameras can be divided into four types for different applications, including fixed, pan/tilt/zoom,
fixed dome and speed dome.
Fixed Type
A fixed network camera points in a fixed direction to monitor a specific area, such as hallways, staircases or
corridors. Because people can be aware of the camera’s shooting direction, in some cases, it can deter vandalism
and crimes.
A fixed network camera usually comes with a RS-232/422/485 interface that connects the cameras to a pan/tilt
scanner for wider coverage.
Many fixed network cameras has exchangeable C/CS-mount lens design, giving users the ability to change the
lens to adapt for different monitoring conditions. For more information on C/CS-mount, please refer to Chapter 2.

Pan/Tilt/Zoom Type
Capable of changing shooting direction horizontally and vertically to achieve a wide field of view, a pan/tilt network
camera is used in many spacious areas, such as lobbies or parking lots.
Some pan/tilt network cameras are integrated with zoom capability so as to provide close-up images of distant
objects. Users can easily control PTZ functions through a web browser.
