Abstract

A method and system of controlling a video surveillance system comprising providing a distributed video surveillance system having a plurality of devices, building a script having a parameter that is filled in when an event occurs, storing the script, detecting the occurrence of an event, loading data related to a first device from the plurality of devices in a first parameter to generate a first script, the first device being associated with the detection of the occurrence of an event, and executing the first script.

Claims

1. A method of controlling a distributed video surveillance system having a plurality of devices connected to a network comprising the steps of:

establishing a protocol for associating the plurality of devices with the occurrence of an event;

storing the protocol;

building a template script that contains a command for an undefined device from the plurality of devices to execute;

storing the template script;

detecting an occurrence of an event;

selecting a device from the plurality of devices according to the protocol to be a device associated with the detected event;

loading data related to the selected device in the template script to generate in real time a first executable script specifically related to the detected event; and

executing the first script automatically without user interaction.

2. A method as recited in claim 1 wherein said step of establishing a protocol comprises selecting a device from the plurality of devices spatially related to the detection of the occurrence of an event.

3. A method as recited in claim 2 wherein said step of establishing a protocol further comprises the step of loading information into the video surveillance system pertaining to the physical location of the plurality of devices in the video surveillance system.

4. A method as recited in claim 3 wherein said step of selecting a device comprises selecting a camera that can view an area physically related to the detected event.

5. A method as recited in claim 1 further comprising the steps of detecting the state of the selected device to determine if the selected device is on-line and loading data related to a second device if the selected device is not on-line.

6. A method as recited in claim 1 wherein said step of executing the first script comprises running the first script at a location remote from the selected device.

7. A method as recited in claim 1 further comprising the step of sending the first script to the selected device and wherein said step of executing the first script comprises having the selected device execute the first script.

8. A method as recited in claim 7 wherein the first script has a variable that is dependent on the selected device and is not filled in before sending the first script to the selected device and further comprising the step of having the selected device fill in the variable to adapt the first script.

9. A video surveillance system comprising:

a network;

a plurality of video surveillance devices connected to said network;

an event detector connected to said network;

a script manager connected to said network, said script manager having a memory, a template script stored in said memory, and a protocol stored in said memory, said template script containing a command for an undefined device from said plurality of video surveillance devices to execute, said protocol associating said plurality of video surveillance devices with an occurrence of an event, said script manager being adapted to select a video surveillance device from said plurality of video surveillance devices according to said protocol to be a device associated with an event detected by said event detector and loading data associated with the selected video surveillance device in said template script to create in real time a completed executable script specifically related to a detected event and to cause the completed script to be executed without user interaction in response to a detected event.

10. A video surveillance system as recited in claim 9 wherein said plurality of video surveillance devices comprise video surveillance cameras and wherein said protocol causes said script manager to select a video surveillance camera that is spatially related to said event detector.

11. A video surveillance system as recited in claim 10 wherein said protocol contains the physical locations of said plurality of video surveillance cameras and said event detector stored in said memory.

12. A video surveillance system as recited in claim 9 wherein said script manager determines whether a video surveillance device is on-line before its data is loaded in said template script and selects another video surveillance device if the selected video surveillance device is not on-line.

13. A video surveillance system as recited in claim 9 wherein said script manager executes said completed script and controls the video surveillance device whose data was loaded into said template script.

14. A video surveillance system as recited in claim 9 wherein said script manager sends said completed script to the video surveillance device whose data was loaded into said template script and said video surveillance device whose data was loaded into said template script executes said completed script.

15. A video surveillance system as recited in claim 14 wherein template script has a variable that is not filled in and said video surveillance device whose data was loaded into said template script fills in said variable before executing said completed script.

16. A video surveillance system as recited in claim 15 wherein said video surveillance device whose data was loaded into said template script comprises a video surveillance camera and wherein said plurality of video surveillance devices comprises a video recorder and said video surveillance camera whose data was loaded into said template script fills in said variable with data pertaining to said video recorder.
