There are many ways to categorize security projects, from the purpose of the need can be divided into: security monitoring, access control, attendance, burglar alarm, building intercom and so on, the need for different, the requirements of the same thing is not the same.
1, security monitoring focuses on monitoring, such as a lot of places need to monitor the line, such as bank counters, institutions, entertainment, traffic sections, these need to be monitored, for one thing, it is impossible for people to do the machine is not tired, two to everyone has their own lives have other things to do, install a surveillance camera, everything is given to it, honestly to you to monitor, and also surveillance video can be called at any time to see. There is also surveillance video can be called out at any time to view, how good ah! There is another point of view, surveillance cameras can be installed many units, and then get a central monitoring room, where each monitor shows something different, find a security guard to sit there and watch, really more than in the myth of the eye to see the six way also cattle!
2, access control and attendance refers to what it is, is the company's employees previously mentioned open the door card, a brush door opened, and some can also play the role of signing, which is the attendance, so access control and attendance are usually said together, and now the popular high-tech, some of the attendance and even the card do not have to use the fingerprints directly with the person as a tool to open the door, and the more cattle face recognition, of course, this is quite high-level stuff. This is quite advanced stuff. And access control can also be based on the needs of the management of different access cards set up different permissions, such as banks often have to use this point, each person's rights are not the same, each other can be held back, so that the role of access control can be a big role in preventing not only thieves, and even thieves can be prevented, the probability of burglary from falling a lot of access control system!
3, the burglar alarm this is not strange, many people have a car, the car parked in the parking lot at night, in case of a big noise inside the car alarm will be barking ah barking, although it does not scare people can at least let the security guards or owners to hear this point is a little bit like a dog to watch the role of home, the only lack of alarms can not be like a dog bites people, huh, joke! The alarm is said to rely on sound to alarm, some rely on infrared alarm, have seen the movie "Across the Four Seas" inside the Cheung Kwok Wing and Chow Yun Fat to steal the art of painting when you have to go through an invisible infrared light, once it is inducted into the immediate alarm; the movie "Crazy Stone" inside the big diamonds on the glass window, once it was moved out of the position of the alarm sounded, the security immediately rushed in, which All illustrate the function of the alarm are based on the need to set up, **** the same point is the need for a trigger to start the alarm, and this trigger point is naturally the thief's theft behavior.
4, building intercom on nothing to say, we have seen too much, go to visit a friend's home, friends if you live in a neighborhood house installed building intercom, then you need to go into the downstairs door will need to pick up the gate on the phone to dial, your friend received the phone know that you are coming, press the open door lock switch in his room, click on the door opened, and then you can go in. The building intercom phone can not be considered a real phone, are inside the line, so the building intercom need to form a small network.
Question 2: What does security mean Security, that is, security systems (SA). Belongs to a subsystem in the intelligent building, including in the weak electricity system. Security systems also include access control systems, closed-circuit television monitoring systems, burglar alarm systems.
Advertising security? My understanding is to do security systems engineering companies and manufacturers to do publicity it.
Question 3: What is the meaning of intelligent security Like in the past, the security ah, most are relying on human defense (a large number of patrol security personnel), physical defense (fences, security gates, cameras, etc.). Take the current security monitoring, almost all the scenes of the monitoring is dependent on people 24 hours a day to stare, such a way of monitoring is very easy to miss dangerous events, so that the monitoring has become an after-the-fact query system, can not find dangerous events in real time. And now intelligent security monitoring is the use of the latest computer vision technology, he can identify the target and prompt you to curb the occurrence of dangerous events in real time
Problem 4: What does it mean to be a security business One, first of all, to get started, right: (to understand the concept and meaning of security) to understand the essence of the meaning of security, to distinguish between the difference between security and Safe, you understand what in the end what it means to be a security in addition to the security. Security includes human defense, physical defense, technical defense, usually referred to as security refers to the technical defense. Second, then to understand the security of several systems video surveillance system access control system (access control system) intrusion alarm system (anti-theft system) patrol system intelligent analysis of intercom systems, listening (not broadcasting) above is the basic system, but a lot of other systems or products in accordance with the industry: gun and ammunition cabinet management system bayonet and red-light capture system management system of the Prosecutor's Office and so on. Third, understand the security industry security itself is an industry, but security covers a very large number of industry applications, almost all industries will be applied, but the most used or financial, law and order, road monitoring, airport security, prisons, museums, and other special must be required to understand the characteristics of the industry in combination with the application of security you can better understand what is security.

Question 5: What is called technical defense? The difference between technical defense and security The so-called "technical defense" usually refers to the use of specialized technical means of preventive measures. Such as the establishment of protective walls in residential areas, reinforced windows and doors, the installation of security doors, the establishment of anti-theft, fire safety alarm system.
"Security" as the name implies is the meaning of security, which covers all areas of property and personal security. We are talking about the security industry, refers to all enterprises and institutions involved in property and personal safety prevention, protection. Security products include products related to anti-theft, anti-snatching, anti-robbery, anti-accident, disaster, etc., such as, closed-circuit (video) monitoring systems and products, intelligent time and attendance systems and products, security patrol systems and products, burglar alarm equipment and products, anti-theft doors, anti-theft locks, firefighting equipment and products, social public **** security apparatus and products, personal security products... ...Wait.
Question 6: security people is what it means mainly refers to the security aspects of the work of the personnel, security industry employment, on the security people.
Question 7: What does security do Security means security.
The security issue is the whole society **** with the concern of a major event, so security is the industry, especially with potentially dangerous high-risk industries need to pay attention to a work.
The security work of various industries by different departments, such as enterprise safety production in China by the State Administration of Work Safety in charge. Social security prevention by the public security department together with social forces *** with the management. Medical-related security is managed by the Ministry of Health and other organizations.
Security mainly includes: monitoring system, infrared perimeter alarm system, home burglar alarm system, building intercom system, parking management system, community card system, three meter reading system.
Security technology
Security monitoring generally includes security and television monitoring, used to be used in financial institutions and important departments, and now more used in all walks of life.
Security includes burglar alarms, access control, electronic patrol, emergency call and so on. Engineering burglar alarm system equipment including alarm host, alarm output devices, alarm linkage equipment, front-end equipment (infrared and microwave intrusion detectors, door and window magnets, vibration detectors, glass breakage detectors, etc.). Door access control mainly includes door opening machine, door access control mainframe, and so on. Electronic patrol system has online and offline type, the host can use ordinary PC and professional software, patrol stick, IB button (placed in the patrol route everywhere). Emergency call includes call button, pair into the equipment, host and so on. TV monitoring currently has digital and traditional analog system, digital because of the current limitations of computer technology, mainly used for digital storage, i.e., digital hard disk recorders, small systems can be embedded systems, using a professional computer operating system, more stable and convenient than the current ordinary computer operating system. Large systems mostly use analog equipment, the center uses a matrix to control the input and output of display and storage devices. Compared with the digital system, the center of the equipment, including the matrix also includes professional long-delay video recorders, field switchers, video switchers. There is basically no difference between the two systems front-end equipment, are used in various types of cameras (fixed, with PTZ, dome, etc.).
Question 8: What is security, security engineering in the end what to do? Security is a safety precaution, including many categories:
Video surveillance, burglar alarm, patrol system, access management, fire and so on.
Video surveillance, burglar alarm, patrol system, access management, fire and so on.
