Construction background:
With the rapid development of society and economy in our country, the scale of cities continues to expand, the population of residents continues to grow, and various social activities are becoming more frequent. In the new situation of increasingly complex social environment, how to further improve urban police security and urban management departments With the efficiency of administrative law enforcement and the enhancement of on-site emergency response capabilities for emergencies, governments and administrative departments at all levels have put forward higher requirements for the application of security prevention technology in the new era. Among them, the wired video surveillance system, as the main application of security technology, can provide accurate and timely judgment and decision-making basis for various incidents such as public security, anti-terrorism, and traffic accidents, and has been widely promoted.
However, the inherent shortcomings of wired video surveillance, such as the inability to move surveillance and respond to emergencies, left some blind spots in the decision-making process of commanders. Although the public security departments continue to expand video surveillance points and increase coverage, there are still blind spots, and these blind spots may be key areas of crime or places where emergencies occur in the future.
On the other hand, the original video surveillance and video recording of various traffic law enforcement, urban management administrative law enforcement, etc. can only rely solely on manual observation and recording of DV equipment, which is inconvenient to operate and has poor timeliness, and cannot be monitored and managed in the background.
The vehicle-mounted wireless video surveillance system can solve the above problems well. With its fast, portable, mobile, and flexible characteristics, it can understand the development and control of the scene in real time. It can be used in actual combat such as dynamic patrol, emergency command, and law enforcement supervision. Play an active role to provide commanders with a comprehensive decision-making basis.
With the rapid development of communication technology and the advent of the 3G era, the combined application of 3G technology and vehicle video surveillance technology provides a more perfect solution for wireless surveillance, which has strong practical feasibility and broad application prospects.
System Overview:
Hongdian’s on-board wireless video monitoring system was born in response to demand, and made various optimizations in software platform and hardware equipment according to actual application conditions, adding corresponding functional modules and business interfaces, and more suitable for on-site application environment and background management control .
Through the real-time return of monitoring images from various types of vehicles on duty, the management department can understand the city’s public security, traffic, city appearance conditions or the scene of emergencies in real time and quickly dispatch personnel to deal with it. On the other hand, it can also perform relevant analysis based on the image data stored in the system. In terms of highway patrols, the system enables the traffic control department to understand the traffic flow of each section in a timely manner, effectively prevent criminal acts on the highway, and provide basic help for the efficient information management of the highway.
Application Environment:
Police patrol highway patrol
Emergency command and monitoring urban management law enforcement patrol
System topology diagram:
System composition:
Video collection terminal: including gun-type cameras and dedicated cameras set up in police patrol vehicles, emergency response vehicles, urban management law enforcement vehicles, and industry management department service vehicles.
On-site collection equipment & vehicle-mounted application equipment (optional): According to actual use requirements and different application types, configure relevant on-site audio collection equipment or other vehicle-mounted application equipment (such as dispatchers, police IP intercom equipment, etc.).
H3225 wireless video server: Choose different 3G formats according to the application environment, support 4-channel video access, realize video encoding and storage locally, and wirelessly upload to the background according to system settings for real-time monitoring and retrieval, execute background control commands, and remotely control cameras And PTZ action, set the alarm preset position, and support WIFI wireless network and GPS vehicle positioning at the same time.
System transmission network: The system is based on the mobile communication operator’s 3G data network for transmission. TD-SCDMA/EVDO/WCDMA standards can all meet the communication applications of this system.
Hongdian on-board wireless monitoring system management platform: Realize the main functions of monitoring site real-time observation, video browsing and image capture, including mobile client access, video display control, alarm linkage and other management functions.
System display, linkage and supporting facilities: mainly including monitoring video wall, display control equipment, linkage system and other interfaces.
System functions:
The vehicle-mounted wireless video surveillance system is used in police patrols, highway traffic patrols, emergency response handling, and urban management administrative law enforcement. It mainly realizes the following functions:
Real-time video surveillance along the patrol and the incident site: Real-time observation of the video information along the patrol road and the incident processing site through a dedicated camera installed on the roof/in the car.
Image recording of patrol process and accident handling process: Local storage, local browsing and uploading to the back-end system through 3G wireless channel of the video record of the service vehicle patrol process and the accident/transaction process process at the place where the incident occurred.
Mobile fixed-point capture: capture images of preset locations or locations where temporary events occur according to usage requirements and upload them to the background management system.
GPS vehicle positioning, driving status monitoring, driving route recording: real-time monitoring of the driving conditions of service vehicles through the built-in GPS, and regulate the behavior of vehicles while ensuring service safety.
On-site wireless broadband networking: The terminal has a built-in WIFI module, which can be used as an AP access point or access terminal to realize fast data transmission on the on-site wireless network.
