Chap.1 IP Surveillance Overview

1.5 Central Management Software

Central management software, often provided by the camera vendors or individual software vendors, enables

customers to manage and control cameras from remote site. Typically, central management software is windows-

based, and thus can be installed in almost any PC.

Central management software employs client-server architecture where server software,client viewing software

and playback software is installed in separate PCs. Customers can perform live viewing, event-triggered recording

or playback on the client PC while managing cameras and performing constant recording with the server PC. Each

server PC can be scaled up to include several subordinate server PCs, and thus expand the number of managed

cameras.

VIVOTEK ST7501 central management software works seamlessly with VIVOTEK’s full-range network cameras

and video servers, helping customers establish a robust, flexible and efficient platform for centralized video

management.

1.4 Network Video Recorders

An NVR (Network Video Recorder) is an IP-based recorder that operates independently from a PC or other

operation systems. Aimed to store digital video streams from network cameras, an NVR is usually incorporated

with a large-volume hard disk to allow for a long period of recording.

An NVR differs from a traditional DVR in its network connectivity, which allows digital data to be transmitted to other

networked devices over the Internet. Another difference is that an NVR can be directly connected to a network

camera while a DVR is usually be connected to an analog camera.
