Abstract

The present disclosure provides a method and system for content management in a video surveillance system. The present disclosure provides content management by which a video management system (VMS) can provide transparent access to video content recorded on edge device storage. The video content access is provided without transferring or copying the video content from the edge device storage to the VMS storage. This access is provided to a client within the VMS framework, without requiring any user intervention to switch or reconfigure connections. The present disclosure also provides a VMS service reflector arranged to reflect services provided by the VMS by having the client establish direct connections to the edge devices when a connection to the VMS is unavailable. The functionality is still provided in the framework of the VMS, and the direct connections are closed when the VMS connection is restored.

Claims

1. A video surveillance system, comprising:

a plurality of edge devices;

a video management system (VMS) in communication with the plurality of edge devices;

a VMS storage, in communication with the VMS, providing local storage to the VMS;

the VMS arranged to record, in the VMS storage, video captured at a selected edge device, the selected edge device being in the plurality of edge devices;

a selected edge device storage associated with the selected edge device, the selected edge device configured to record, on the selected edge device storage, video captured at the selected edge device; and

a video content reflector arranged to provide, to a client, transparent access via the VMS to video content on the selected edge device storage without transferring the video content from the selected edge device storage to the VMS storage.

2. The system of claim 1 wherein the video content reflector is integral with the VMS.

3. The system of claim 1 wherein the video content reflector is arranged to provide transparent access to the video content on the selected edge device storage via a VMS interface associated with the VMS.

4. The system of claim 1 wherein the video content reflector is integral with the selected edge device.

5. The system of claim 1 wherein the video content reflector is integral with the one of the plurality of edge devices.

6. The system of claim 1 further comprising:

a VMS service reflector, in communication with the client and with the VMS and with the plurality of edge devices, the VMS service reflector arranged to reflect, to the client, services provided by the VMS when the VMS is unavailable, the VMS service reflection being performed by way of direct connection to the plurality of edge devices.

7. The system of claim 6 wherein the VMS service reflector comprises:

a configuration information extractor arranged to obtain configuration information from the VMS regarding the plurality of edge devices managed by the VMS; and

a client connection manager arranged to transparently connect the client directly to the plurality of edge devices based on the obtained configuration information.

8. The system of claim 7 wherein the client connection manager transparently connects the client directly to the plurality of edge devices based on the obtained configuration information in response to receipt of an indication of a loss of a connection along a VMS-client connection path.

9. The system of claim 7 wherein the VMS service reflector, for the duration of unavailability of the VMS, is arranged to provide VMS functionality through the existing VMS interface via the direct edge device connections in a manner that is transparent to the client, to disconnect the direct edge device connections in response to receiving an indication of re-establishment of the client connection, and to maintain the VMS functionality transparently to the client through the loss and re-establishment of the client connection.

10. The system of claim 6 wherein the VMS service reflector is integral with the client.

11. The system of claim 6 wherein the video content reflector is a primary video content reflector, and further comprising a secondary video content reflector arranged to provide, to the client, transparent access via the VMS to video content on the selected edge device storage without transferring the video content from the selected edge device storage to the VMS storage and in the case of failure of the primary video content reflector.

12. A method of implementing content management in a video surveillance system, the system including a video management system (VMS) having VMS storage, a plurality of edge devices each having associated therewith an edge device storage, and a client, the method comprising:

recording video captured at a selected edge device in the plurality of edge devices on a the VMS storage;

recording video captured at the selected edge device on a selected edge device storage, the selected edge device storage being associated with the selected edge device; and

providing, to the client, transparent access via the VMS to video content of the selected edge device storage without transferring the video content from the edge device storage to the VMS storage.

13. The method of claim 12 further comprising:

obtaining, at the client, configuration information from the VMS regarding the plurality of edge devices managed by the VMS;

receiving an indication of a loss of a client connection along a connection path between the VMS and the client;

in response to the received indication of the loss of the client connection, transparently connecting the client directly to the plurality of edge devices based on the obtained configuration information;

for the duration of the loss of the client connection, providing VMS service reflection through an existing VMS interface via the direct edge device connections in a manner that is transparent to the client;

disconnecting the direct edge device connections in response to receiving an indication of re-establishment of the client connection; and

maintaining the VMS functionality transparently to the client through the loss and re-establishment of the client connection.

14. A method of implementing content management in a video surveillance system, the system including a video management system (VMS) having VMS storage, a plurality of edge devices each having associated therewith an edge device storage, and a client, the method comprising:

obtaining, at the client, configuration information from the VMS regarding the plurality of edge devices managed by the VMS;

transparently connecting the client directly to the plurality of edge devices based on the obtained configuration information;

providing VMS service reflection through an existing VMS interface via the direct edge device connections in a manner that is transparent to the client; and

maintaining the VMS functionality transparently to the client through the loss and re-establishment of the client connection.

15. A non-transitory machine readable medium storing statements and instructions for execution by a processor to perform a method of implementing content management in a video surveillance system, the system including a video management system (VMS) having VMS storage, a plurality of edge devices each having associated therewith an edge device storage, and a client, the method comprising:

recording video captured at a selected edge device in the plurality of edge devices on a the VMS storage;

recording video captured at the selected edge device on a selected edge device storage, the selected edge device storage being associated with the selected edge device; and

providing, to the client, transparent access via the VMS to video content of the selected edge device storage without transferring the video content from the edge device storage to the VMS storage.

16. The non-transitory machine readable medium of claim 15 wherein the method further comprises:

obtaining, at the client, configuration information from the VMS regarding the plurality of edge devices managed by the VMS;

receiving an indication of a loss of a client connection along a connection path between the VMS and the client;

in response to the received indication of the loss of the client connection, transparently connecting the client directly to the plurality of edge devices based on the obtained configuration information;

for the duration of the loss of the client connection, providing VMS service reflection through an existing VMS interface via the direct edge device connections in a manner that is transparent to the client;

disconnecting the direct edge device connections in response to receiving an indication of re-establishment of the client connection; and
