The construction of urban video surveillance system is an important foundation for urban safety and stability, an important part of the construction of a "safe city", and an important carrier of a "smart city". As high-definition monitoring technology matures, "high-definition" has become an inevitable trend in the construction of safe cities. The city video surveillance system has shifted from a "visible" video security system to a "clear" high-definition safe city networking system, and has followed the "build for use, use for war" principle, and began to "see clearly" Intelligent system construction.
How to build a safe city that "sees clearly, sees clearly", how to build a sharing system that integrates various resources, and how to build a monitoring system that serves the public security business are the difficulties faced by public security informatization in the new situation.
推出了高清平安城市解决方案，为公安机关开展治安防控、侦查办案、指挥决策等综合应用提供核心全局服务支撑。 Combining with the development trend of safe cities, Pilot Guards is based on the needs of urban security prevention and management. Around the construction of five major prevention and control circles of safe city security control, Pilot Guards has launched a high-definition safe city solution for public security organs to conduct security prevention and control, investigation and handling cases, Comprehensive applications such as command and decision-making provide core global service support.
The high-definition safe city solution relies on the safe city comprehensive application management platform to build a safe city high-definition security monitoring system, high-definition bayonet monitoring system, high-definition electronic police system, high-definition personnel bayonet system, mobile police system, and social video resource integration system. , Scientifically optimize the monitoring layout to achieve full coverage of "points, lines, and areas", thereby establishing a three-dimensional prevention and control system of global long-distance grasp, regional proximity sensing and close-in-depth observation.
(1) Comprehensive HD video experience
From acquisition, transmission, storage, control to display, it provides users with a comprehensive high-definition experience. 1080P@60fps 编解码能力，相对于普通监控画面可获得更清晰、更流畅的视频画面；采用业内领先的高保真低码率算法，720p只需1~2Mbps码率，1080p只需3~4Mbps码率，相对于原有高清监控可节省一半以上的传输带宽和存储空间；中心显示设备采用拼接大屏幕，屏幕本身支持1080P甚至更高的物理分辨率，可全面实现高清画面的效果。 The front end supports different high-definition solutions such as network high-definition and digital high-definition, and supports 1080P @ 60fps encoding and decoding capabilities. Compared with ordinary monitoring pictures, it can obtain clearer and smoother video pictures. It adopts the industry-leading high-fidelity low-bit rate algorithm, 720p Only 1 ~ 2Mbps code rate is needed, 1080p only needs 3 ~ 4Mbps code rate, which can save more than half of the transmission bandwidth and storage space compared to the original high-definition monitoring; the central display device uses a large splicing screen, and the screen itself supports 1080P or higher. The physical resolution can fully realize the effect of high-definition pictures.
In addition, high-definition monitoring also greatly improves the accuracy of intelligent analysis algorithms, which is conducive to intelligent applications such as video retrieval, behavior analysis, and face recognition. At the same time, Hikvision has launched smart IPC, which uses intelligent coding, intelligent detection, and intelligent The controlled "technology set" is supported, and supports cross-border detection, face detection, scene detection, audio detection, etc.
(2) Local video surveillance experience
Scientifically optimize the monitoring layout, reasonably plan the monitoring points, and combine special cameras for different scenarios to build a hierarchical city video surveillance joint prevention and control system, which provides a good infrastructure foundation for public security agencies to implement in-depth video applications and effectively serve the public security struggle.
The HD bayonet capture camera integrates video capture, video processing, and license plate recognition functions, and supports multiple detection modes such as coil detection, video detection, and composite detection to ensure a high capture rate of the system.
The high-definition electronic police integrated machine has built-in independent intellectual property rights for traffic vehicle detection, identification, and violation detection algorithms, and a video tracking algorithm based on vehicle contours, which greatly improves the reliability of violation detection.
The high-definition fog-transmitting camera adopts advanced real-time fog-transmitting technology to realize effective monitoring under severe weather such as haze, sand, and overcast, and to ensure the needs of urban public security monitoring, traffic road monitoring and so on.
A new generation of mobile individual terminal, IP67 three-proof design, with professional features such as 1080P video, 1080P network transmission, built-in applications such as face recognition, certificate recognition, license plate recognition, cluster intercom, etc., to help public security agencies to achieve mobile police applications.
提供高清高速球机、高清红外摄像机、热成像摄像机、人脸抓拍机、移动车载、出入口控制、报警门禁等全线安防产品，服务于公共安全的各种应用场景。 In addition, Pioneer Guards offers a full range of security products such as high-speed high-speed dome cameras, high-definition infrared cameras, thermal imaging cameras, face capture cameras, mobile vehicles, access control, alarm and access control, etc., serving a variety of public safety applications.
(3) Efficient intelligent analysis application
Multi-type intelligent analysis application experience, changing passive monitoring to active prevention.
Face capture comparison experience, for people who go in and out of security checkpoints, perform face capture comparison, and provide intelligent applications such as blacklist warning, personnel deployment, face retrieval, and large database comparison, which are beneficial to real-time deployment and control of suspects .
Intelligent patrol and patrol experience supports the detection of personnel gathering, area appearance, rapid movement, cross-line alarm, area invasion, personnel wandering, items left behind, illegal parking, etc., which is conducive to the timely detection of abnormal conditions in the jurisdiction.
In addition, the system supports video intelligent fast retrieval applications such as video abstracts and video retrieval to improve the efficiency of video viewing; the system supports intelligent image processing applications such as image enhancement and image restoration, highlighting or suppressing some features in the image, and making details of the image It is clearer and improves the sensory effect of the picture.
(4) Comprehensive system comprehensive operation and maintenance services
The stable operation of the system is to ensure the normal operation of various services. Hikvision considers users to provide a comprehensive network monitoring and management system that supports front-end cameras, back-end video equipment, business servers, storage equipment, network equipment, databases, and intermediate. Real-time monitoring and management of various equipment and resources such as software, business application systems, and power room environment, effectively reducing potential hidden dangers of the system.
Video quality diagnosis technology is introduced to support real-time monitoring of camera abnormalities such as video loss, color cast, blurred images, fringe interference, snowflakes, etc., which is helpful for system operation and maintenance personnel to detect front-end equipment failures in a timely manner.
