Chapter I General
1.1 Introduction
Digital surveillance center management software aka. Client Software, is a comprehensive tool for
managing networked surveillance devices including; network video servers, network cameras and
networked digital video recorders. You have complete access to networked devices for centralized
monitoring and storage as well as providing management and control of networked video devices.
This central management software supports video switching of 1, 4, 9, 16, 25, or 36 images,
bi-directional audio, log retrieval, alarm control, and remote retrieval playback. Powerful
functionality, a user friendly interface, and easy operation makes this software ideal for small and
medium sized surveillance systems.
1.2 Factors Influencing System Performance
When designing a system, you must consider the performance of the entire system, the factors
influencing your system, and the settings making your system operate at an optimized
performance level. Bandwidth is your primary consideration, other factors such as frame rate and
an excess of connections to the central management software will influence the frame rate of the
server. Heavy traffic on the network will slow video transmission while the connection to the
servers (DVRs) will also slow the network for other users. One last factor to consider is the
capability of the PC hosting the center management software. Motion video is resource intensive
for a PC, use of a PC with a powerful CPU, maximum RAM and a good graphics card will result
in a better experience with your central management software connection.
