SmartArgos: Improving Mobile Surveillance Systems with Software Defined Networks

http://cns2015.ieee-cns.org/content/posters

Abstract --- Mobile surveillance systems like vehicle mounted cameras (i.e. police dash cams) and body cameras play an important role in securing physical spaces ... generate too much data that hampers timely analysis ...
not sufficient bandwidth ... time streaming of videos to backend servers.

SmartArgos, a control framework to regulate mobile surveillance systems. SmartArgos uses software defined networks and computer vision algorithms to manage multiple mobile surveillance streams.

By networking ... cameras together to a common backend server, we can remotely monitoring multiple physical spaces using fewer personnel ...
The collected videos ... streamed from the cameras to the a backend system via wireless networks.

A common problem to both mobile and static surveillance systems
the potential to generate too much video to be observed efficiently in real time.
SmartArgos
a framework that uses software-defined networking to regulate the transmission of videos from mobile platforms.
intuition
use computer vision algorithms … prioritize more important video streams
use software-defined networks (SDN) to regulate the bandwidth so that more important videos uploaded to the backend server faster.

II. SMARTARGOS ARCHITECTURE

Filtering module
takes in n input video streams, and outputs a subset of k streams to display to the personnel monitoring the situation.
Once the k streams are selected, the backend server uses the Floodlight controller to instruct the intermediate switches to throttle the remaining n − k streams.
Triggering module
… mobile device sends a command to the backend server, which then instructs the Floodlight controller to increase the bandwidth for the mobile device and begin uploading the video stream at a faster rate

III. PRELIMINARY RESULTS

SmartArgos will coordinate different types of mobile cameras, including vehicle-mounted ones, cameras mounted on drones, as well as body worn cameras.

IV. CONCLUSION

control mobile surveillance used in physical security
SDN to control the available bandwidth for different mobile devices
support different computer vision implementations to help identify the necessary data from the video streams
