Visual Surveillance Features

Raspberry Pi?

The Raspberry Pi is a credit-card-sized single-board mini computer

Contains 512MB memory with 700MHz Processer and ability to clock up to 1 GHz, and a Video core 4 GPU. The GPU is capable of Blu-Ray quality playback. It has a fast 3D core accessed using the supplied OpenGL ES2.0 and OpenVG libraries

The GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode

The GPU is capable of 1Gpixel/s, 1.5Gtexel/s or 24 GFLOPs of general purpose compute and features a bunch of texture filtering and DMA infrastructure

That is, graphics capabilities are roughly equivalent to Xbox 1 level of performance. Overall real world performance is something like a 300MHz Pentium 2, only with much, much swankier graphics

Visual Data Stats

Size per image ~ 500 KB (rough average)

Duration of transmission 18 hours daily (assuming intercity travel)

Image frequency 3 images/minute*

Number of images transmitted each day 3240

Daily data transmission ~ 1.55 GB (rough approximation of core transmission)

Local storage in Raspberry Pi 16 GB (current SD card size, expandable to 64 GB)

Data Storage Capacity ~ 10.5 days worth data

Web Panel Features

Web Panel Data Flow

Maps

• Displayed using Google Maps

• Each map will correspond to a specific trip

• Various zoom levels

• Route direction and location accuracy are offered

• All data is exportable in csv format for offline manipulations & analysis

Maps – Contd..

• Portable to other map services – one instance of Leaflet JS is implemented to showcase the feature

• Custom route deviation is implemented which generates an SMS alert using sendsms.pk API to the admin to inform about deviation from the pre-set route

Archived Visual Data

• Archived to be used for future references.

• All data is exportable

• Visual evidence

• Monitor their services and customer experience as well

Integrated View

• An integrated view has been incorporated in the system to view the visual data corresponding to the trip location tracking for better vigilance

Route Creation/View

• Customized routes

• Can be modified at any time

• The saved routes can then be viewed for verification purposes

Reporting Generation

• Standard reporting module

• Scalable

• Exportable in .pdf format

Types of ReportsUser Report

Three Tier Contingency Plan

Level 3:Cellular Network/Wi-Fi Failure

Android Application will locally store data in the device, which can be later extracted and pushed onto

the web server via customized C# application

Images will be stored in Raspberry Pi Micro SD card and can be extracted manually to be pushed on

to the web server

LEVEL 2: GPRS/Wi-Fi FailureAndroid Application will switch to secondary mode, SMS, to send information in a pre-set format to be

pushed on to the web server via SMS server.

Images will be stored in Raspberry Pi Micro SD card.

LEVEL 1: Temporary Connection LossAndroid Application will wait and resend once

connectivity is restored.

Images will be stored in Raspberry Pi Micro SD card and transmission will resume when connection

restores.

Data Security

• Secure password protected My SQL database hosted on a dedicated server

• User dashboard has clearly defined user roles, eliminating unauthorized usage

• Authorized users can access relevant information only

• Passwords of all the registered users are protected using ONE-WAY HASH function

Data Security – Contd..

• All data is viewable only once logged in

• End-to-end image transmission to remote server is encrypted using AES 256

Data Security – Contd..

• AES 256 Encryption:

– Image converted to HEX String.

– Hex String is encrypted using AES encryption

– Image is transmitted via web service to VTMS Server

– Cipher text is decrypted to plain text.

– Hex String is converted to binary data.

– Stored as LONGBlob in MYSQL DB

System Limitations• Since Integration of visual surveillance is the latest addition,

it has greater room for improvements

• Constant power supply for the Video Surveillance unit

• Wi-Fi connectivity for visual data transmission

• Limited number of location update requests, Google allows 10,000 requests per month, exceeding limit results in incurring additional costs

System Limitations – Contd..• The system is semi-automated. There is some, though

minimal, interaction required from the user

• Hardware compatibility may be an issue

• Improved crisis response time doesn’t necessarily means timely crisis response

• Deals with monitoring only, no direct response action

Challenges

• Rigorous testing required - creating a favorable environment for controlled tests. Also Identifying plausible issues of intercity travel

• Finding and acquiring compatible hardware for the system to work optimally

• Crafting complete and comprehensive documentation
