Safety and prevention work is in the building and residence, to take "air defense", "anti-matter", and "technical defense" means the combination to protect the people in the production, life, personal and property safety, and production and living facilities from being damaged . The main means of including in the prevention of zones, security personnel (air defense), the construction to prevent equipment (anti-matter), the use of surveillance and communication technologies to prevent the establishment of security system. Mainly by the security system video surveillance systems, intrusion alarm systems, patrol system, access control (access control) system, car parking management system and the composition of visitors intercom systems. Its basic meaning is the integrated use of computer network technology, communication technology, electronic information technology, safety technology, an advanced, the economy, supporting the safety and security system.


Technical requirements 1. Video Surveillance System
(1) should be based on the management of security technology to prevent the need for a place to be monitored, location, access and other real-time, effective video surveillance, detection, transmission, display and recording. And should have the linkage alarm and image review functions.


(2) monitoring the screen display should be able to any programming and can be automatically or manually switch, monitor screen should display the camera number, location, time and date of the necessary information.


(3) the monitoring system should be run from a network independent and can and intrusion alarm systems, access control (access control) system control linkage. When the alarm occurs, the alarm automatically to the site to review the images and sound, can automatically switch to the specified site images displayed on monitors and automatic recording.


(4) with the central control room should be able to network, to achieve control room on the video surveillance system, centralized monitoring and management.


(5) technical requirements for video surveillance systems should refer to the relevant provisions of GA/T367.


2. Intrusion Alarm System (1) under the management of security technology to prevent the need for maximum security area of the illegal invasion, theft, vandalism and robbery, effective real-time detection and alarms, and review by the alarm function.


(2) intrusion alarm systems are generally from the detector, the regional controller and the alarm control center composed of three parts. Usually a regional controller, the detector coupled with sound and light alarm devices can constitute a simple alarm system. Systems that require higher security control center must be set, so can play on the intrusion alarm system, security system management and the integrated management role.


(3) intrusion alarm system's basic requirements:
fortified area on the illegal invasion of real-time, reliable and accurate alarm and review, to avoid leakage, false alarm.


alarm system shall be a network, run independently, with the output interface can be manual, automated approach to the wired or wireless communications systems outside alarm. 110 is reserved with the local public security alarm center network interface.


system should be able to press time, location, regional any programming, or disarm defenses.
should be able to run the state of equipment and signal transmission line testing, fault alarm will be issued timely and direct fault location.


should have the ability to prevent damage, destruction or when the detector circuit is cut off, the system can be reported immediately.


the system can display alarm location, area, time, can print, record, filed for the record, and can provide video surveillance and alarm linkage, lights and lighting control interface signal.


important part in the important area and send alarm signals, the system can sound the alarm on-site verification.


(4) intrusion alarm system can be divided into a multi-alarm alarm and two, should be based on the complexity of the deployment region choose a different system. Usually advised to use a simple alarm system, complex multi-level alarm system should be selected. An alarm system should be set one alarm controller, multi-level alarm system should be set to a concentration of more than one area alarm controller and the alarm controller and can strain network.


(5) should be adopted in the important region has deployed more than two means of alarm detection and increase the reliability of alarm. Use of different types of alarms in different locations such as: switching alarm, glass breaking sensor should be installed in the doors and windows positions; passive infrared, Doppler microwave alarm suitable for installation in indoor; active infrared, microwave alarm block device suitable for installation in open air; voice alarm system should be used in conjunction with other types of alarm; video motion alarm and video surveillance systems for use. In such establishments, cashier, duty office position should be set up emergency alarm device.


(6) alarm installation should pay attention to: switch alarm switch in accordance with the requirements of different types of installation; infrared, microwave, alarm system installed in the room should be kept to 2-2.4 m away from the wall or ceiling installation , and the detection direction to maintain 45 ° -90 ° angle. Outdoor enclosure with the detector should be used in rain, fog, frost prevention, shading functionality.


Intrusion alarm system technical requirements should refer to GA/T368 in the regulations.
