Type of Cameras
A fixed security camera points in a single direction, which is ideal for monitoring specific areas, and very effective for deterrence against vandalism and criminal activity. Typically, a fixed camera is the preferred choice when it works in your favor to have cameras installed in clearly visible locations. Once the camera is mounted, the viewing direction is set. For added flexibility, some fixed cameras accept interchangeable lenses and housings for both indoor and outdoor use. A bullet camera, for instance, is a fixed surveillance camera contained within a protective housing. These cameras sometimes feature integrated LEDs for peak performance in extreme low-light or no-light conditions.
PTZ cameras work great for flexible wide-area surveillance and detailed monitoring. With a PTZ camera, you can control pan/tilt/zoom functions to follow activity and zero in on specific individuals and objects within a scene. These functions are controlled either manually or automatically, and sent along with the camera’s video transmissions over a single network cable when using IP cameras. Analog cameras, on the other hand, require additional wiring to perform similar functionality.
Offering an expansive field-of-view, along with fast and accurate pan/tilt/zoom functions, speed dome cameras are primarily used for professional applications such as airport and bank security, and municipal surveillance. Speed domes enable full 360-degree panning for monitoring large areas. In many cases, a single speed dome can provide the same amount of coverage as 10 fixed cameras, though it can’t point in all directions at once. Most speed dome cameras provide a guard tour mode for continuous monitoring between different preset positions.
Usually designed for indoor surveillance applications, a fixed dome camera features a fixed camera contained within a small dome housing. Fixed dome cameras are also sometimes called mini domes. The main benefit of this type of camera is the discreet design which allows for unobtrusive surveillance. Unlike regular fixed cameras where the monitoring direction easily visible, fixed dome cameras typically make it difficult to see which direction the camera is pointing. Fixed domes with vandal-proof and outdoor housings are available for more demanding surveillance applications.
