1, peace - eternal topic
With the deepening of reform and opening up and rapid urban and rural economic development, a significant increase in urban floating population and bring the community many unstable factors, Zhian situation is becoming increasingly severe, Xing Shi case Tebie yes burglary theft, robbery increased incidence Lv. Therefore, the state departments concerned on the comprehensive management of social order, and to create a safe and civilized communities as one of the important content. Meanwhile, to further standardize the construction of residential community intelligence, particularly the Ministry of Construction has developed standards for intelligence community's level, according to their requirements intelligence community must have a safety precaution, information management, property management, information network and other subsystems. Therefore, community building security system has gradually incorporated into many of the essential community development projects, and to Shenzhen, for example, virtually all new residential properties for sale are pre-installed home security systems, and to prohibit the installation of security networks, but also spent heavily in Guangzhou remove anti-theft network, its security features will inevitably be transferred to the electronic anti-theft system to complete. Therefore, construction of residential community security system in the next few years there will be rapid growth, and also from Beijing, Shanghai, Guangzhou, Shenzhen and other developed cities to coastal areas and spread to the mainland.
2, the bottleneck - the traditional solution
At present, the general community security surveillance systems mostly using the traditional simulation-based transport solutions, or based on digital hard disk video recorder (DVR) in the semi-digital solutions, these solutions there are many bottlenecks: firstly requires a lot of wiring construction, video cable , control line, alarm lines, power lines, ... ... etc., followed by simulation-based system in the video store, share, remote transmission has inherent deficiencies, the last even if you DVR the semi-digital solutions in the system's capacity expansion, upgrading and video transmission has many limitations.
3, digital - solution
Network Video Server is the third generation all-digital video distributed / centralized control system of core equipment, are the latest type of digital surveillance products, which allows the traditional camera captures the image and the alarm sensor alarm signals digitally encoded processing, through local area network , wide area network, wireless network, Internet or other network transmission to the network extends to any place, thousands of miles away through the common computer network users can conduct real-time remote monitoring of images, video, management. Network video server network-based real-time transmission of dynamic image features, so in the past must be confined to the region-wide video surveillance system, to become free from time and geographical constraints.
Application network digital video server security system to achieve the above-mentioned issues will be resolved, first of all, high-end community-based information network transmission, the system more flexible deployment, and get rid of cumbersome wiring construction, and secondly, because front-end control point will convert the analog signal digital information flow, therefore, whether it is remote, local control, or with other systems (such as community information management, community property management, patrol system, remote meter reading systems, access control systems, etc.) have become easy integration.
4, analytical - Security monitoring requirements
Intelligent video surveillance system is an integral part of the community, mainly the importance of gathering the community entrance, each unit entrance, parking access, and various public places and other key areas of video surveillance images, the shift to community monitoring in real time to the whole community site conditions; and able to control each channel video images, real time recording, playback video file retrieval and management centers via a network remote monitoring and control.
In order to better guarantee the safety of communities, the installation perimeter of the fire alarm system is to alert the community to implement the perimeter. Alarm equipment with four-beam infrared detector on the radio, install fences and gates in the community above the active infrared detector on the radio transmitter and receiver, a reasonable place to prevent the
