Red Apple Electronic Security City HD Network Solution

The purpose of urban public security monitoring system is to combat and prevent illegal crimes. Video monitoring points are set up in places with complex public security, key parts, main streets, case-prone areas, important intersections, estuaries and other places, and the monitoring images are transmitted to public security organs at all levels and other relevant departments in real time. By browsing and recording images, public security organs at all levels and other relevant departments can intuitively understand and master the public security dynamics in the monitoring area, and effectively improve the level of social security management.

First, demand analysis:

Video demand

The setting of video monitoring points in urban video monitoring is the focus of urban public safety. These control points are mainly concentrated in commercial financial streets, communities, entertainment venues, main road sections and transportation hub areas. The control point is mainly equipped with equipment such as image acquisition, audio acquisition and alarm information acquisition.

Relevant departments need to know the real-time situation of monitoring in various sensitive areas of the city through images, and the requirements for real-time image transmission must be high definition, small delay and coherence; According to the actual demand, even in some particularly important areas, high-definition image acquisition points are arranged. Only in this way can the managers of functional departments master real-time, clear and high-quality video images in the first time. ?

With the deepening and promotion of the construction of "safe city", the monitoring scope and quantity of public security monitoring systems in various cities are becoming wider and wider; The types (SD, HD, network, analog) and brands (different protocols and algorithms) of front-end video capture cameras included in the whole system are becoming more and more complicated, and the requirements for control compatibility and supervision are getting higher and higher. In addition, with the increasing number of video monitoring points, especially the increasing number of high-definition video points on the network, higher requirements are put forward for video monitoring display and control (that is, image control and wall-hanging equipment).

Second, the overall system solution of Red Apple:

1. In view of the fact that there is no unified construction standard at present and the construction progress and specific solutions vary greatly from place to place, Red Apple still adopts the modular combination mode with clear framework and strong compatibility. After expansion or transformation, the multi-level networking system such as the matrix built in the early stage can be seamlessly integrated into the new system, including the interconnection of the matrices of police stations, sub-bureaus and municipal bureaus with the same brand centered on the audio and video matrix in the early stage, the uploading, publishing and authorization control of video signals, or the multi-level networking system with other brands in the early stage, which can be interconnected and controlled with the newly built Red Apple matrix networking system.

2. At present, the monitoring scope, quantity and scale of urban public safety monitoring system are getting wider and wider. Red Apple PE60S high-density network matrix, single machine capacity can achieve 5 12 input or 128 output, and the whole system can be extended to 65535 super-large capacity, meeting the requirements of super-large systems. Theoretically, the number of video point accesses in the whole system will be unlimited.

3. In view of the complexity of different brands (different protocols and algorithms) and different standard types (standard definition, high definition, network and analog) of various front-end cameras in the monitoring center, Red Apple chose the PE90FH HD digital matrix system to make a perfect solution. PE90FH high-definition digital matrix system can not only support high-definition and standard-definition analog video signal input, but also switch output at will; Through Red Apple's professional streaming media forwarding server, it can be compatible with mainstream high-definition cameras and high-definition ball machines on the market; The streaming media forwarding server encodes cameras of different brands in the front end into standard RTSP streams, which are decoded by high-definition matrix and then directly output to the TV wall.

4. In terms of controlling and solving the problem of wall mounting, the Red Apple PE90FH HD digital matrix can be networked with matrices of different brands in other sub-centers to realize interconnection and mutual control, and the front-end video images of the original system can be controlled and monitored under reasonable authorization. The large-scale wall-hanging equipment PE90FH high-definition digital matrix of the whole system can directly mount and control various standard definition, high definition, network and analog video images. The system supports the input exchange and mixed splicing of SD/HD video, and can realize the segmentation and splicing of video images, that is, intercept any part of the input video and send it to other daughter boards for processing, scaling, superposition and splicing. Support video merging, that is, multiple input videos can be merged into one video; Support video superposition, which can generate at most two layers of video to realize superimposed display; Support geometric correction and brightness correction, completely possess and surpass the function of the large screen controller in the monitoring center, replace it and improve the cost performance of the system.

1) traditional control center video wall hanging solution;

In the traditional solution to solve the problem of video uploading, it is necessary to be compatible with different types of video uploading, such as high definition, standard definition, analog and digital. Therefore, different types of matrices such as AV, RGB and DVI need to be configured, and an image controller is needed to realize the complex processing of video images. The system is complex and expensive; Many devices are needed, and there are many faulty nodes between devices.

Red Apple PE90FH HD digital matrix solution abandons all kinds of matrix devices and directly uploads and controls all kinds of SD, HD, network and analog video images, with the function of image controller.

5. The digital part of the whole system takes the management platform as the core. The central management platform of the sub-bureau not only carries out unified scheduling, streaming media, centralized storage and downloading, but also registers and manages all front-end equipment and access users, including front-end monitoring point equipment and users on the operator network.

① The servers of Red Apple PE5060 series system control software platform mainly include: main control management server, streaming media management server, GIS map information management server and various function management servers such as alarm and centralized storage. The configuration and number of specific servers should be determined according to the scale of system construction and the number of videos. Its main management server is the core of the whole system control software platform.

② The main responsibility of the main management server is to manage the matrix and embedded DVR in this area, authenticate the operation authority of authorized users, and control the front-end equipment of network matrix (DVR, DVS parameters, PTZ control, etc.). ), and complete the main monitoring function in this area. Achieve security management (user rights distribution, login authentication, etc.). ), logging, configuration management, centralized monitoring and mirroring, and network-wide security management; In the form of electronic map, the layout or connection diagram of monitoring points in the area and the police station and the operation diagram of equipment are displayed respectively, and there are auxiliary interfaces such as image window, alarm window, communication connection window and control window. Maintenance personnel can directly access the required interface through the local station/equipment tree and electronic map.

③ It can be combined with GIS geographic information map and GPRS positioning system of traffic police, and with video images or other alarm signals to form various functional schemes. Connected together through local area network, and connected with other application platforms through network. Other application platforms refer to departments that * * * enjoy monitoring system data except equipment maintenance departments, such as security departments, administrative departments and other management departments. These application platforms can also obtain real-time data and historical data services.

④ The main control server has a voice alarm function. When an alarm occurs, the voice prompts the name, location and alarm level of the alarm. At the same time, when an emergency alarm occurs, such as power failure, fire, Fei Jing, etc. , use the alarm function.
