Event Driven Video Surveillance System using City Cloud A solution compliant with Sensor Web Enablement Architecture

2

Motivation

• Manual monitoring in traditional video surveillance system is

tedious and error prone.

• Cumbersome and time consuming manual process for event

retrieval from huge archive.

• Lack of interest based alert dispatch mechanism.

• Problems in storage of large binary data.

• Constraints on display devices.

Highlights of our work

Deliverable :• A framework for generating real time event dashboard using video analysis.• Event based classification and dispatch of events to registered subscribers.• Mechanism for third party app developers to query stored events via web-services.• Blob storage of video event in remote server.• Metadata storage in geospatial database• Device agnostic rendering on plethora of connected devices.

Scope of work :Development of Video capture, Edge analytics , event and metadata generation ,event display and

posting to Backend server

Out of scope : Storage,event retrieval and query at backend server

Conclusion

• An event triggered video surveillance system is proposed.

• Publishing of selective events to dedicated customer can make

the solution citywide applicable.

• Backend can be hosted on cloud based platform for intelligent

city application

• The picture quality, average latency between publishing and

receiving of events depends on video codec, camera

specification and network speed respectively.

• Lack of standardization on video codec support for HTML5 fails

to suggest any specific browser for universal viewing purpose.

Any Question?
