HD safe city solution

(I) Background and Challenges

The construction of an urban video surveillance system is an important foundation for achieving urban security and stability. It is an important part of the construction of a “Safe City” and has become an important carrier for “Smart City”. With the maturity of high-definition surveillance technology, "high-definition" has become an inevitable trend in the construction of a safe city. The urban video surveillance system has been transformed from a "visible" video security system to a "clear" HD and safe city networking system, and has followed the principle of "building for use, using for the war" and began to "see" Intelligent system construction.

How to build a "safe and easy-to-understand" city, how to build a shared system that integrates various types of resources, and how to build a monitoring system for public services, is a difficult problem in the process of public information construction in the new situation.

Combining with the development trend of Safe City, Hikvision focuses on the needs of urban security management and prevention. Focusing on the establishment of five major prevention and control loops for safe urban governance, Hikvision launched a high-definition, safe city solution to prevent and control public organizations. Comprehensive application of investigation, case handling, and command and decision-making provide core global service support.

(B) Solution

HD Safe City Solution Relied on Safe City Integrated Application Management Platform to build a safe city HD surveillance system, HD bayonet monitoring system, high-definition electronic police system, HD personnel bayonet system, mobile policing system, and social video resource integration system Scientifically optimizing the monitoring layout to achieve full coverage of "points, lines, and surfaces", thus establishing a three-dimensional prevention and control system for long-distance global understanding, regional proximity perception, and close-range in-depth observation.

(c) user value

(1) Full HD video experience

From the acquisition, transmission, storage, control to display, provide users with a comprehensive high-definition experience. The front-end supports various high-definition solutions for network HD and digital HD, and supports 1080P@60fps encoding and decoding capabilities. Compared with ordinary monitoring screens, it can obtain clearer and smoother video images; it adopts the industry-leading high-fidelity and low-rate algorithm, 720p Only 1~2Mbps bit rate, 1080p only 3~4Mbps bit rate, compared to the original high-definition monitoring can save more than half of the transmission bandwidth and storage space; center display device using a large mosaic screen, the screen itself supports 1080P or even higher Physical resolution, can fully achieve the effect of high-definition screen.

In addition, the high-definition monitoring also greatly improves the accuracy of the intelligent analysis algorithm, and is conducive to intelligent applications such as video retrieval, behavior analysis, and face recognition. At the same time, Hikvision introduced smart IPC to smart coding, intelligent detection, and intelligence. The "technology set" of control is a support and supports cross-border detection, face detection, scene detection, and audio detection.

(2) Local video surveillance experience

Scientifically optimize the layout of monitoring, reasonably plan monitoring points, combine special cameras for different scenarios, and build a joint prevention and control system for hierarchical video surveillance in cities, so as to provide a good infrastructure for the public to implement deep video applications and effectively serve the public real struggle.

The HD bayonet capture camera integrates video capture, video processing, and license plate recognition functions. It supports various detection modes such as coil detection, video detection, and composite detection, ensuring the high capture rate of the system.

High-definition electric police integrated machine built-in independent intellectual property rights of the vehicle detection, identification, violation detection algorithm, video tracking algorithm based on vehicle contours, greatly improving the reliability of violation detection.

High-definition fog-mist adopts advanced real-time fogging technology to achieve effective monitoring under hazy weather, dust, haze and other bad weather, ensuring urban governance monitoring, traffic road monitoring and other needs.

The new generation of mobile individual terminal, IP67 three anti-design, with 1080P video, 1080P network transmission and other professional features, built-in face recognition, document identification, license plate recognition, cluster intercom and other applications to help the public agencies to implement mobile policing applications.

In addition, Hikvision provides high-speed dome cameras, high-definition infrared cameras, thermal imaging cameras, face capture machines, mobile vehicle-mounted, entrance control, alarm access control and other full-line security products to serve various public safety scenarios.

(3) Efficient intelligent analysis applications

Multi-type intelligent analysis application experience, changing passive monitoring to active prevention.

The face-snapping comparison experience enables the face-to-face comparison of personnel entering and exiting the card slot, providing intelligent applications such as blacklist warning, personnel deployment, face retrieval, and large database matching, which is conducive to the real-time deployment of suspects. .

Intelligent patrol prevention experience, support for personnel gathering, regional presence, rapid movement, cross-line alarms, regional intrusion, personnel flaws, legacy items, illegal parking, etc., are conducive to timely detection of abnormal conditions within the jurisdiction.

In addition, the system supports video intelligent quick retrieval applications such as video abstraction and video retrieval to achieve the purpose of improving video viewing efficiency. The system supports intelligent image processing applications such as image enhancement and image restoration, highlights or suppresses some features in the image, and makes the image detail features Clearer, improve the sensory effects of the screen.

(4) Perfect System Integrated Operation Service

The stable operation of the system is to ensure the normal operation of various services. Hikvision regards the user as providing a comprehensive monitoring and management system for the entire network, supporting front-end cameras, back-end video equipment, business servers, storage devices, network equipment, databases, and middleware. The real-time monitoring and management of various types of equipment and resources, such as parts, business application systems, and machine room power environment, effectively reduce the potential risks of the system.

The introduction of video quality diagnostic technology supports real-time monitoring of camera abnormalities such as video loss, color cast, image blurring, fringe interference, and snowflakes, facilitating the timely detection of front-end equipment failures by system operation and maintenance personnel.
