Safe City Solutions
Making a City or a Campus Safe is much more than placing cameras in the field and monitoring those cameras. Complete Operations comprise of many elements that are seamlessly integrated into a single cohesive and efficient Surveillance and Security fabric spanning the entire space to be secured. The following are the components in a typical ‘Safe City’ Solution:
High Speed Private Dedicated Terrestrial Fiber-optics Based Network
Network spanning the entire city (or campus) and must have redundancy at all levels with no single point of failure. Furthermore, the Network has to designed and optimized for High-Definition (HD) Video transport with minimal latency.
Dedicated (Or Shared) Lte/4g Wireless Network
This Network Exclusively for use by the Police force and users. The Wireless network must be fully integrated with the Safe City Systems Terrestrial Network. The primary function of the Wireless Network will be to support HD Video and Voice applications on mobile Assets in the field and the secondary function will be to serve as a backup link channel in case of Terrestrial Network outages.
Main Data Centre
This will host all the Safe City Systems Information and Data Processing and Storage Equipment in addition to Core Routing and Switching gear. The Data Centre must be designed as Certified Tier 3 Data Centre as defined by the 2010 ANSI/TIA Telecommunications Industry Association (TIA). The Tier-3 Data Centre must have at a minimum of multiple independent distribution paths serving the IT equipment. All IT equipment must be dual-powered and fully compatible with the topology of a site's architecture. In addition, the site concurrent maintainable infrastructure must have an expected availability of 99.982%.
Disaster Recovery Centre
This will host an identical set of Information and Data Processing and Storage Equipment along with Core Routing and Switching gear. The purpose of this Centre is to act as a ‘Shadow’ to the main Data Centre with near real-time replication (using a ‘heart-beat’ replication method). The Disaster Recovery Centre must ensure Zero or near-zero data loss and support Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs) of a Tier 6 DRC. Tier 6 DRC's maintain the highest levels of data currency. They are used in operations where there is little or no tolerance for data loss and where there is a need to restore data to applications rapidly.
Specialized Control Rooms
Control rooms will comprise of several ‘Control Rooms’ in the same facility as the Main Data Centre. Each control room must have a distinct and prescribed method of operation. Each control room must be equipped with an appropriate combination of Hardware, Systems and supporting process for specific 'Role-based' operations. Safe City Systems must have the following Control Rooms in the main facility
All Control Rooms must be connected to the Safe City Systems Fiber Network through high-speed and redundant Access switches located in the Safe City Systems Main Data Centre as well as the Disaster Recovery Centre. The Control Rooms must have appropriate lighting to ensure the maximum visual clarity for Video Displays, monitors and other LCD / CCD displays for operators. Furthermore, the Control Rooms must have continuous Power and a Back-up power supply, which must be a combination of Grid, UPS and Batteries, and Generators to supply power contiguously for 24x7x365 with no possibility of disruption due to power failure.
Integrated Software Applications Suite
At the heart of the Safe City Systems, there must be a host of applications and sub-systems residing on servers in the Data Centre. The applications will be integrated into a single Cohesive System and User Interface offering rich functionality to Safe City Systems operations staff using a ‘Role-Based’ access and features model.
High-Definition Special and General purpose Video Cameras must be installed on Stand-alone Poles and overhead Gantry’s throughout the city. All Cameras used throughout the Safe City Systems City-wide implementation are IP-based as well as LTE/4G enabled. In addition, the Cameras conform to the latest ONVIF standard for control features. The cameras are optimally placed to provide coverage of all major entrances and exits to the city, all major infrastructure and buildings, universities /educational institutes, traffic signals, identified crime pockets and other identified areas of interest. All Stationary cameras are connected to the Video Surveillance System at the Main Data Centre as well as the Disaster Recovery Centre via the private and dedicated Fiber Optic network. There are three specific types of stationary cameras:
- PTZ – Pan – Tilt and Zoom
- ANPR – Automatic Number Plate Recognition
