What is? Security monitoring ？ Do you know what security projects are?
What is security? Many people may not know what security is when they first heard about it, and some have never known the existence of such an industry. But there is a classic saying, "Don't know doesn't mean it doesn't exist". The security industry is not known by the public, but it still exists objectively. In fact, examples of security applications are everywhere in daily life. For example, in addition to the traffic lights at intersections, there are also those surveillance cameras, otherwise those drivers who drive illegally through the traffic lights or hit people can escape;
For another example, many companies now issue each employee with a company door opening card, which is often referred to as "door access card". With him, we can enter and exit the company freely, but it is not so easy for external personnel. This is very good for preventing some door-to-door marketing harassment;
In some communities, a call device is installed at the gate of each unit. If you want to enter the first gate, first dial the room of the person you are looking for, then the person above will connect your call, confirm your identity, press the button on the top, and the lower door will open. From this point of view, the application of these security projects is very common in our life, but most people do not know the word security.
Is security high-tech? In itself, it is not high-tech. High tech is the security products, but you can't say that security has no technical content. The schemes and quotations designed by a good security engineer are different from those of a poor security engineer. Their security projects have different effects. Some of them break down easily, some have fatal risks, but some are used well without any problems. For example, we have a good security engineer who knows almost everything, It's easy to solve any problem, big or small. People call it professional! Not everyone can do a good job in the security project. It requires dedicated people and knowledgeable people to pay the crystallization of wisdom to do such things well.
The classification of security projects can be divided into several categories for purposes, but they are all based on their own needs, including security monitoring Access control attendance , anti-theft alarm, building intercom, etc., the requirements are different.
A、 Security monitoring focuses on monitoring. For example, many places need to be monitored, such as bank counters, government agencies, entertainment places, and traffic sections. For one thing, it is impossible for people to be tireless with machines. For another, everyone has their own life and other things to do. Install a monitoring system video camera Well, let's leave everything to it, and let's monitor it honestly. And the surveillance video can be called out at any time to check. How nice! In addition, there are many surveillance cameras that can be installed, and then a central monitoring room can be set up. Each monitor in the room displays different things. Finding a security guard to sit there and watch is really better than the mythical view!
B、 What does access control and attendance refer to? As mentioned above, the door opening card of the company's employees can be opened as soon as they swipe the door, and some can also play the role of sign in. This is attendance. Therefore, access control and attendance are usually said together. Now high-tech is popular, and some of the attendance tests do not even use the card, but directly use human fingerprints as a tool to open the door, Even better is face recognition, which is quite advanced. In addition, the access control can also set different permissions for different access cards according to the management needs. For example, banks often use this point. Everyone's permissions are different, and they can check each other. This kind of access control plays a great role, preventing not only external thieves, but also domestic thieves, thus reducing the probability of self theft, The access control system contributes a lot!
C、 The anti-theft alarm is no stranger to us. Many people have cars. When the car parks in the parking lot at night, the alarm in the car will bark and bark when it is louder. Although it doesn't scare people, it can be heard by security guards or car owners. This is a bit like a dog watching the home! The alarms mentioned above are sound alarms, and some are infrared alarms. The common point is that a trigger is needed to start the alarm, and this trigger is naturally the theft of thieves.
D、 There is nothing to say about the building intercom. Everyone has seen too much. Go to visit a friend's house. If a friend lives in a community house equipped with building intercom, you need to pick up the telephone on the door to dial if you want to enter the downstairs door. When your friend receives the call, he knows you are coming, presses the door lock switch in his room, and clicks the door open, Then you can go in. In fact, the building intercom phone is not a real phone, but an internal line, so building intercom needs to set up a small network.
It can be seen from this that security is the protection measures collected for the needs of their own safety, security engineering is the process of achieving security protection, and security products are the equipment serving the security engineering.
