Introduction to the five high-definition system solutions in Safe City

With the maturity of high-definition surveillance technology, “HD” has become an inevitable development trend in the construction of safe cities. Ping An City video surveillance system has been turned from a “visible” video security system to a “clearly clear” HD safe city networking system, and has followed the principle of “building for use and use for war” and started to “see clearly”. Intelligent, practical system construction.

How to build a safe city that "see clearly and understand clearly", how to build a monitoring system for service actual application, how to build a shared system that integrates various resources is a difficult problem in the process of public security information construction under the new situation.

In response to the development of safe city construction, and guided by the actual demand of public security, a new generation of high-definition safe city solutions was launched. The video surveillance system was innovated around the collection of video information, the storage organization of video information, and the application of video information. Sexual redesign provides core global service support for public security departments to carry out comprehensive applications such as public security prevention and control, investigation and handling, and command and decision.

3, high-definition electronic police system

HD electronic police system adopts 200/300/5 million high-definition intelligent capture camera, supports 1~3 lane monitoring, integrates card-passing record, electric police illegal detection, video monitoring, road traffic parameter collection function, and can be built in the city. Highway intersections, ramp entrances, single-lane roads, etc., enable all-weather monitoring of traffic vehicles and record illegal processes in real time.

Application features:

(1) High-definition video electric police integrated machine built-in detection, identification and violation detection algorithms for traffic vehicles with independent intellectual property rights;

(4) The electric police capture unit can output high-definition video stream while completing the capture to meet the requirements of high-definition video surveillance;

(5) Support data breakpoint retransmission function. When the network is interrupted, the vehicle information is stored in the front-end device, and will be automatically renewed after the fault is eliminated.

4, HD staff bayonet system

The face capture comparison system developed according to algorithms such as face detection, recognition, tracking and quality scoring of independent intellectual property rights is applicable to important card points such as stations, airports, subways, communities, hotels, banks, etc., to realize face capture and people. Face recognition, face retrieval and query applications.

Application features:

(3) Establish a face information database to provide features such as blacklist warning, personnel control, and face retrieval;

(4) Support large Kubbi equivalent extension applications.

5. Mobile police system

OFweek Electronic Engineering Network News: Due to the incomplete monitoring network coverage, there is a blind spot in public security management. Based on its own research and development strength, it develops on-board forensics and individual combat solutions for mobile policing to solve the task of public security patrol and police on duty. There are problems such as difficulty in law enforcement, difficulty in communication and communication at the higher level, and difficulty in obtaining evidence on the spot.
