Abstract

The present invention relates to a backup system for digital surveillance system comprising video cameras, main server(s), networking facilities, a data-switching system, management server(s), backup server(s) and a central control station of an existing surveillance system, wherein a plurality of the video cameras connect to the main server(s); the microprocessor(s) of the main server(s) is installed with software which compresses recorded backup images in real time and the main server connects to the networking facilities; the data-switching system connects to the networking facilities and the management server(s); the management server(s) connects to the backup server(s) and the central control station; the microprocessor(s) of the management server(s) is installed with software which continuously monitors the operation of the main server(s) via the networking facilities, directs the backup server(s) to take over the function of the main server(s) to compress and backup data when malfunctioning occurs, and switches on alarms for malfunctioning indication. The present invention supports a plurality of main systems with one backup system and supports a plurality of video cameras with one main system. It effectively enhances the effectiveness of the backup system.

Claims

1. A backup system for digital surveillance system comprising video cameras, main server(s), networking facilities, a data-switching system, management server(s), backup server(s) and a central control station of an existing surveillance system, wherein a plurality of the video cameras connect to the main server(s);

the microprocessor(s) of the main server(s) is installed with software which compresses recorded backup images in real time;

the main server(s) connects to the networking facilities;

the data-switching system connects to the networking facilities;

the data-switching system connects to the management server(s);

the management server(s) connects to the backup server(s) and the central control station;

the microprocessor(s) of the management server(s) is installed with software which continuously monitors the operation of the main server via the networking facilities, directs the backup server(s) to take over the function of the main server(s) to compress and backup data when malfunctioning occurs, and switches on alarms for malfunctioning indication.

2. The backup system for digital surveillance system as in claim 1, wherein each of the main server(s) can connect to up to 16 video camera(s).

3. The backup system for digital surveillance system as in claim 1, wherein each of the backup server(s) can support up to 10 main server(s).

4. The backup system for digital surveillance system as in claim 1;

wherein the networking facilities connect to a data transmission network available in the marketplace such as Local Area Network (“

LAN”

), Internet, Integrated Services Digital Network (“

ISDN”

) and others by real time networking.

5. The backup system for digital surveillance system as in claim 1, wherein the central control station connects to the networking facilities and is provided with a monitor which shows video images.
