In recent years, modern high technology and information technology (it) are moving from intelligent building (IB) to intelligent residential district, and then into the family. In the “implementation plan of 2000 well-off urban and rural residential science and technology industry project”, the state has listed the construction of intelligent well-off demonstration district as the national key development direction, Therefore, it is inevitable to promote the development of intelligent technology from intelligent building construction to intelligent community and even family. The construction of intelligent well-off demonstration community is listed in the national key development direction, so it is inevitable to promote the development of intelligent technology from intelligent building construction to intelligent community and even family.
In order to further meet the high standard requirements of social and economic development and people’s civilized life, create a safe, comfortable, warm and efficient office and living environment. In order to ensure the security and anti-theft of the community, the intelligent community video monitoring system provided by belsson is installed in a community.
The intelligent community video monitoring system needs to monitor the perimeter of the community, main entrances and exits, parking lots, squares, main intersections, etc. the system has the functions of automatic graphics switching, fixed-point display and multi screen display. The system can record all images in real time for viewing or reference. The top management department is the operator of the main control room. The system adopts three-level architecture. Each monitoring site is the first level, which is mainly the collection of video source, mainly the installation of camera, ball machine shield, decoder and bracket; The video transmission and control signals are set up as two levels; The main control room is set in the Network Center for monitoring and image forwarding, and has the functions of TV wall and distribution control. It is the third level (it provides the reserved function, which has been provided by the system). This level has the main control center, which can watch any video image of each monitoring site, and has the functions of identity authentication, authority management, control and image forwarding, It has the functions of electronic map management and center large screen monitoring.
Intelligent community video monitoring management system uses advanced computer real-time detection and control, computer network, computer communication, multimedia and database and many other advanced technologies to connect the scattered field computer with the main control computer of the monitoring room to form a computer distributed monitoring system.
All cameras are color cameras, community along the main road, intersections, complex sections: the use of fast ball
CCTV monitoring system should be said to be an interdisciplinary and cross industry system engineering, which can be divided into the following aspects according to different functional requirements:
1. Front end camera system
2. Video transmission system
3. Video control system and video display and recording system
System topology diagram:
1. Front end camera system
The camera part is the front part of the video monitoring system and the “eye” of the whole system. It turns the monitored content into an image signal and transmits it to the monitor of the control center. The quality of the camera part and the image signal it produces will affect the quality of the whole system.
Beiersun be-mp130 / IR infrared network camera is used in the residential area. The camera uses double filters, which effectively solves the problem of double peak filters. When the light is sufficient in the daytime, the infrared cut-off filter works, and the CCD restores the true color; When the light is insufficient at night, the infrared cut-off filter automatically moves away, and the full spectrum optical glass starts to work, so that the CCD can make full use of all the light, greatly improve the low illumination performance, and provide a clearer picture
2. Video transmission system
The access effect of the front-end video encoder and the video browsing effect of the client are closely related to the network bandwidth. They have different requirements for the network bandwidth and are directly affected by the network bandwidth. Therefore, the selection of appropriate lines will play a crucial role in the whole system. Therefore, in the choice of transmission channel, Caiwuwei xinqifang community uses a special LAN access network monitoring mode. The monitoring network as a separate network, and then into the LAN core, with the entire community network to form an organic whole.
3. Video control system, video display and recording system
The control part is the “heart” and “brain” of the whole video monitoring system, and is the command center to realize the functions of the whole system. The video display part is the embodiment and significance of the functions of the whole monitoring system.
The monitoring center is set in the information network center, mainly including integrated monitoring management server, monitoring workstation computer, video decoder, monitor, etc. The integrated monitoring management server is the management center and control center of the whole intelligent community video monitoring system. Responsible for front-end monitoring camera management, video stream receiving and forwarding, video storage management, back-end video decoder management, monitoring workstation management, account allocation, authority management, etc. Within the account and authority granted by the integrated monitoring management server, the monitoring workstation can view real-time video images and historical video data in multi screen form.
The video decoder in the monitoring center decodes the front-end word video into analog video and outputs it to the TV wall composed of multiple monitors to display all video images in a round robin manner, and the large screen in the middle displays the images of key areas in the form of four pictures. Under the management of the integrated monitoring management server, the video decoder can make any video output to any screen pane of any monitor, realize the function of digital matrix, and make the whole community along the main road, intersections, complex road sections and channels at a glance.
With the further stability of network camera performance and the increasingly reasonable price, the intelligent community video monitoring system will be gradually popularized in each community. Beiersun intelligent community video monitoring system enables the security staff of each community to provide safe, scientific and effective protection for the whole community. It can implement all-weather and all-round monitoring, analysis and recording of important intersections, public places, key equipment anti-theft, fire prevention and waterproof in the community, so as to strengthen on-site supervision and safety management, It can also prevent the occurrence of terrorist incidents, make the security management of the whole community more standardized, scientific, accurate, information-based and intelligent, and become a strong technical guarantee for the security management of the community.
