Design principles
The overall design of the system in accordance with the requirements of national and local relevant laws and regulations, technical standards, uphold the active digestion and absorption of domestic and foreign advanced experience and technology, based on the domestic, safe and reliable, thrifty and practical, easy to expand and manage the maintenance of the principle. The principles followed in the construction of this project:
(1) Advanced technology
Due to the rapid development of information technology, while taking into account the practicality and high reliability of the system, the design and construction of the system must be forward-looking, as far as possible the use of advanced technology and development tools to ensure the advanced system and products;
(2) Practical principles
Fully do a good job of demand research, and site survey to determine the actual location, research and analysis of installation location, video angle, design reasonable and practical, really built a unified, practical video surveillance system.
(3) Compatibility principles
The system is designed to take into account the compatibility of the industry's mainstream well-known brand equipment, and can communicate with other monitoring systems, while providing an open SDK software interface and secondary development interface, for the future multi-system linkage (such as alarm systems, electronic fences, access control, etc.) to lay a good foundation.
(4) Reliability Principles
As the key link of the stable operation of the system, reliability includes network reliability and equipment reliability, the whole monitoring system establishes a set of independent video transmission network, the equipment adopts mature, stable and universal technology and equipment, the key parts have backup, redundancy measures, there is strong fault tolerance and system recovery ability.
(5) Scalability principle
Mainly in the horizontal and vertical expansion capabilities, in the system scale-out, the system in order to meet the current video surveillance needs, on the basis of the system can be very convenient to expand capacity. In terms of vertical expansion, the system should have good compatibility and general-purpose hardware and software interface, through system upgrade, expansion and other ways to achieve good expansion, to ensure the overall development needs in the next 5.
(6) The principle of security and confidentiality
There are two main aspects to the security and confidentiality of the whole video surveillance system: the network environment and data storage. The system adopts the design of the private network, the storage of the video image is concentrated in the room, browsing and downloading or copying have strict user rights and approval methods, users at all levels can only call the video information within the scope of this permission.
(7) Openness and standardness
The system involves a large number of departments, should be an open, easy-to-expand, distributed system. System design involved in the technology and selected products should be the industry's finalists of the mainstream products, in line with the industry's latest standards, and have a good openness, with the relevant systems to connect and share data.
(8) Easy to operate and maintain:
The system is simple to operate, the application software interface is friendly, and the information processing is simple, convenient and fast. System data backup and data recovery is fast and easy.

(1) Firearms (ammunition) warehouse risk classification and safety precautions requirements (GA 1016-2012)
(2) Ethernet 100BASE-T/1000 BASE-T Standard IEEE802.3
(3) GB/T 13993.2-2002 Communication Fiber Optic System
(4) Security Prevention Video Surveillance Networked System Information Transfer, Exchange, Control Technology Requirements (GB/T 28181-2011)
(5) Safety And Safety Engineering Specifications (GB50348-2004)
(6) Safety Engineering Procedures and Requirements (GA/T75-94)
(7) Safety System Acceptance Rules (GA308/2001)
(8) General Graphic Symbol for Security Systems (GA/T75-2000)
(9) Technical Requirements for Video Security Monitoring System (GA/T367-2001)
(10) Industrial TV System Engineering Design Specification (GB 50115-2009)
Design goals
(1) Video security monitoring system should be able to carry out effective video detection and monitoring, image display, recording and playback of protective targets and doors and vents in the gun (ammunition) warehouse interior.
(2) The image quality of the video security surveillance system shall not be less than the requirement of 5.0.10 in GB 50395-2007, the video image at the entrance and exit area should be able to clearly distinguish the facial features of the person in and out of the person, and the video image of the warehouse room should be able to clearly display the movement of personnel and access to firearms and ammunition. Additional auxiliary lighting or the use of cameras with night vision should be added when the illumination does not meet the requirements;
(3) Video security monitoring system should have the function of measuring and recording the mobile screen frame, the frame measurement sensitivity is to the camera focus area has personnel, vehicles or should be guarded object when moving, the image recording continuity index shall not be less than 25 fps;
(4) Video security monitoring system should be able to record all monitoring images, can multi-screen or timing display of each monitoring image, can be linked to the alarm system, when the alarm occurs, can be the alarm scene image review, and the scene image automatically switched to the designated monitor display;
(5) Firearms (ammunition) room video security monitoring data retention time shall not be less than 30d;
(6) Video surveillance system can be linked to intrusion alarm system;
(7) The safety prevention system should be equipped with a backup power supply, when the main power supply power failure should be able to ensure that the monitoring center and safety prevention system power supply time is not less than 8h;
(8) The firearms (ammunition) warehouse security system should be repaired within 48h after a malfunction. During the maintenance of the system, emergency plans should be activated for supplementary protection.
