In recent years, with the rapid development of China's economy, the living standards of urban and rural residents have significantly improved, especially the living conditions of urban residents have been continuously improved. After solving the housing problem, people are increasingly concerned about whether their residence is safe. When buying a house, safety is an important condition for evaluating the level of property management. Especially for criminals who commit crimes by wandering around, they often choose residential areas as their attack targets. Cases of burglary, robbery, and murder occur repeatedly, and the previous prevention measures mainly relying on community reporting and civil defense can no longer meet people's requirements. With the rapid development and widespread application of communication technology, security monitoring technology, and computer network technology, using security prevention technology for security prevention first has a deterrent effect on criminals, making them afraid to commit crimes easily. Intelligent communities are gradually developing and growing,The pace of information infrastructure construction is also accelerating. How to provide residents in the community with an efficient, comfortable, warm, and convenient environment And it can also meet the constantly changing needs of users,Implementing unified, orderly, intelligent, and networked management for residential areas is an urgent issue that needs to be addressed in community security management. The security system of the community and the on/off alarm of doors and windows can timely detect the time and location of criminals' crimes, making them afraid to take action easily.

Design of Technical Scheme for Closed Circuit Monitoring System

Design Philosophy

Conducting closed-circuit monitoring(CCTV)When designing systems engineering, we adhere to the basic requirements for closed-circuit monitoring systems, with a focus on reasonable architecture, safety and reliability, mainstream products, low cost, and low maintenance. Based on this, we provide customers with advanced, safe, reliable, and efficient solutions.

Reasonable architecture: It means adopting advanced technology to construct the system in a reasonable manner, ensuring the safe and stable operation of the entire system, and having good expansion conditions for the future.

Stability: This is the most concerning issue for residential communities, and only a stable operating system can ensure closed-circuit monitoring(CCTV)The smooth operation of the system and the progressiveness technology of the system are the guarantee and basis for the high performance of the system, and can effectively reduce the trouble of users and system maintenance personnel.

Security: The system must be a secure system to ensure reliable operation.

Scalability: Ensure that when users have more requirements, the introduced new devices can smoothly work together with the current equipment, further expanding and improving the performance of the system.

Product Mainstream: Whether the system adopts current mainstream products is related to the overall quality of the system and whether it can receive good technical support and complete technical documentation in the future.

When selecting equipment, we will mainly consider the technical progressiveness of the product manufacturer, whether the product is mainstream, the integrity of the product technical data of the original manufacturer, the technical support of the original manufacturer and the development prospect of the product manufacturing company based on the specific requirements of the user. All of these are the conditions to ensure that users receive good technical support and are also the basic conditions to guarantee user investment.

　 Low cost and low maintenance: Refers to striving for a good performance price ratio, using products that are simple, easy to operate, maintain, and highly reliable. Whether a system has excellent performance price ratio is an important basis for judging the advantages and disadvantages of a system. The ease of operation and maintenance of a system are the conditions for ensuring that non professionals can use it well. High reliability is a fundamental requirement for ensuring system operation and also a guarantee of maintainability.

Our company will design the closed-circuit monitoring system based on the above design principles. We will strictly follow international practices and combine our company's technical strength and engineering experience to carry out the installation, testing, and acceptance of the closed-circuit monitoring system project. Upon completion, we will submit installation and usage manuals for each equipment related to the project, as well as various system charts and other documentation. We will also make commitments to technical training and services.

Intelligent community perimeter fire alarm system

In order to better ensure the safety of the community, installing a perimeter shooting anti-theft alarm system is to implement surveillance around the community perimeter. The alarm device adopts a four beam infrared detector, installed above the perimeter walls and gates of the community. The emitting and receiving ends of the active infrared detector are placed reasonably to prevent the occurrence of monitoring blind spots.

150The active infrared detector, also known as the photoelectric intrusion detector, works by actively emitting and receiving infrared energy, without generating false alarms or missed alarms due to changes in the environment. One end emits infrared energy signals, while the other end receives infrared signals, forming several horizontal linear blocking barriers similar to traffic barriers. Therefore, the contact surface between the active infrared beam and space is very narrow, thereby minimizing false alarms to the greatest extent possible.
