Creating a secure and serene environment is essential for cities to develop and thrive. With increasing urban densities, cities need more advanced technologies to safeguard people and property. In years past, urban management relied entirely on manpower to ensure safety – police and private security guards. With the emergence of video technologies, cities welcomed a much more efficient way for keeping a sharp eye on things. Now, a very basic surveillance system makes first response and crime investigation much easier and faster.
This is, of course, only the first step to more efficient and intelligent urban management. The graph below shows the general evolution of a safe city. More than just intelligent applications, eventually the insights gained from this process could generate surprising new applications, enabling any safe city to be perpetually improving.
Basic City Surveillance
Build CCTV surveillance systems that cover critical areas of a city and integrate video data between such areas to visualize the underlying security status at city levels.
Intelligent Video System
Implement AI capabilities and applications on top of public security resources to promote the intelligent transformation of a city’s video system, turning video into IoT data. Clients will likely benefit from higher efficiency in patrols, law enforcement, and resource scheduling at this phase.
Data Fusion and Sharing
Fuse IoT data generated in the intelligent video system with data from information networks according to practical business needs, then provide value-added services and applications. Clients will quickly enjoy precise situational awareness around a city.
Following the course of action outlined above, it is easy to see that any Safe City development will be a multi-phase process. Each step into a new phase brings new possibilities and opportunities. The graphic below shows a full range of control systems provided by Hikvision for these phases.
Ground Control System
Hikvision offers security cameras designed for complex urban scenarios to meet public security needs. The Ground Control System is the foundation of the urban security infrastructure. The cameras in key locales and on main city roads continually provide valuable information for decision makers.
Air Control System
By deploying high zoom-rate PTZs, positioning systems, PanoVu cameras, drones, and anti-UAV equipment at the high points of the city, an airspace protection system is formed. The mixture of dynamic and static nodes and the combination of global perception and detail capture makes the Air Control System an integral part of urban security.
Mobile Control System
Fixed monitoring usually covers important urban scenes, but is limited in scope. For the city as a whole, this means there will still be some blind spots. The Mobile Control System is tailored to solve this problem. The system consists of body-worn cameras and portable PTZ domes for flexible and agile responses, enabling rapid deployment in emergency situations and where fixed monitoring is not available or feasible.
Alarm Control System
Installing an Alarm Control System will greatly reduce human resources, but this needs to be built on strict accuracy. Hikvision’s Smart Detection Technology ensures that alarms received by the command center are valid and worthy of a response. At the same time, implementing emergency alarms in the city will enhance the sense of security for civilians as police officers can make video calls with people who are at risk and threatened before an event occurs.
Intelligent Control System
As AI technologies evolve, urban security enters an exciting, new intelligent era with unprecedented improvements in efficiency. With vast AI capabilities and a deep understanding of the video-based security industry, Hikvision integrates its proprietary deep learning algorithms into intelligent perception devices in edge domains and powerful computing devices in the cloud. Ultimately, this produces effective and precise data and provides even more functional security applications based on that data.
The five layers of control systems come together to create comprehensive coverage of a city, but this is not enough. A complete Safe City will inevitably require the construction of a central system. This will be the brain connecting thousands of devices in the city. In order to create a visualized, real-time, and intelligent central system, Hikvision provides a range of central equipment from fail-safe video storage solutions, high-definition large-screen displays, and transmission to central computing, big data, and AI-algorithm training facilities. Moreover, Hikvision also offers a powerful application system to provide and share its rich, multi-dimensional application capabilities based on data processing and analytics.
The large number of video resources placed in the city during the first phase lay the ground work, so that intelligent upgrades in the second phase will generate abundant data. This becomes the city's IoT Data, which, combined with clients’ business information, will help deepen understanding and enable localized urban security systems and services.
System development throughout the above three phases will be based on AI Cloud architecture, in which Edge Nodes, Edge Domains, and a Cloud Center will be allocated to adapt to the various scenarios of the Safe City Solution, meeting requirements at each level and from a variety of organizations.
Cloud Center: Comprehensive Applications
Fusing business data and the application of multi-dimensional big data analysis
Edge Domain: Cross-Scene Applications
Intelligent applications and the collection, storage, and processing of data
Edge Node: Single-Scene Applications
Collecting data from multi-dimensional sensors and front-end processing
