What are the main technologies of smart security?

1) Big data.

In the intelligent security of smart communities and large-scale intelligent community building complexes, it is necessary to obtain the best information 7x24 hours, which is a massive amount of data and belongs to big data. Therefore, the development characteristics of big data are:

The transition from non-digital to digital is now nearing maturity.

The key to digitalization is structure.

Mass transformation of unstructured to structured data, data centralization is key.

A lot of data is contradicted by fast processing.

The most important thing in the application of big data is that the data is concentrated, and only by centralizing the data can the data be analyzed and processed, and the information value that can be used can be mined. Smart transportation, smart community, smart security, safe city, data, information integration, integrated management, etc. are all applied to big data technology.

Security refers to "security protection". Security by physical defense, civil air defense, technical defense three forms of protection, where the security engineering refers to technical prevention.

Security engineering is to realize the use of modern scientific and technological means to achieve the process of security protection, security products are the equipment that serves the security engineering.

The characteristics of smart security include informatization, visualization, intelligence, security and so on.

1. Informatization.

2. Visualization.

Adopt advanced and integrated data processing technology, equipment interconnection, improve command and dispatch efficiency and reduce labor costs.

3. Intelligence.

Terminal security access management provides a variety of secure access authentication methods to ensure the front-end access security chain, and analyze lost data for analysis and maintenance.

4. Safety.

Comprehensive permission control and management to ensure the safe use of data and prevent human destruction.

Examples of smart security:

After the user leaves home, there is a natural gas leak at home, which triggers the device to generate an alarm signal, and the alarm signal is sent to the user's mobile phone in real time, and the user obtains the alarm information at the first time, which can be quickly handled.

If the device is connected to the indoor unit and the property management office is networked and the alarm management is carried out at the same time, the alarm signal will be sent to the Chanxu community security office synchronously, and the community security will receive the alarm signal to do a good job in emergency treatment.

Once someone illegally intrudes into the room, the door and window sensors will immediately link the security equipment, send out sound and light alarms, push the intrusion information to the user's mobile phone, and automatically record it, and at the same time link the home camera to shoot and video, which has a predictive effect.

Usually, miniature door and window sensors are installed at entrances and exits, doors and windows, and are the first warning line for residential security. The device is connected to the gateway device, unified management, and linkage with the rest of the smart security equipment. Such as gas leakage alarms, flood alarms, smoke alarms, and home cameras are used for linkage prevention and control, forming an Internet of Things security management.

A complete intelligent security system probably consists of the following equipment:

Monitoring system, alarm controller, smart door lock, human body sensor, infrared sensor, wind and rain sensor, combustible gas sensor.

Compared with the traditional security system, the intelligent security system not only plays the role of monitoring, but also can connect various sensors to make the security more comprehensive. Oribo intelligent security system as a convenience: you go to work in the company, someone sits on a customer to break into the home, the human body sensor detects that someone is walking around the house, automatically triggers the alarm and calls the camera to record, and then pushes the information to your mobile phone and displays the real-time image of the home.

In addition, when you are away from home, the gas leakage at home, the combustible gas sensor can be detected and the automatic curtain can be linked to open the window to avoid the danger of excessive gas concentration.

At present, the products and technologies involved mainly come from:

1. Door magnetic, when leaving home

The technology used in intelligent security to copy is mainly as follows: du

Visualization techniques.

The security system is as follows:

1. Emergency broadcasting system.

Emergency Broadcast System In 1997, the system was replaced by the Emergency Alert System (EAS).

2. Building intercom system.

The building intercom system is mainly composed of the main engine, extension, UPS power supply, electric lock and door closer. According to the type, it can be divided into direct press type, digital type, digital household pass, direct press video intercom, digital video intercom, digital household video intercom, etc.

3. Access control system.

The access control system is in the field of intelligent buildings, which means access control system, abbreviated as ACS.

4. Digital monitoring system.

The digital monitoring system refers to the processing of the image collected by the surveillance camera into a digital signal through software and hardware, and transmits it to the computer for processing.

5. Parking lot management system.

The parking lot management system is a set of network systems built by computers, network equipment, and lane management equipment to manage the entry and exit of parking vehicles, traffic flow guidance in the parking lot, and the collection of parking fees.

In addition, it also includes gas fire protection system, digital patrol system, perimeter alarm system, elevator five-party alarm system, and key centralized management system.

The intelligent security system is composed of three parts: access control, alarm and monitoring, and the main functions are as follows.

The gateway is mainly the local sound alarm, voice alarm, SMS alarm, MMS alarm and other notification type.

Emergency SOS When someone in the family has an accident or is threatened by an outside, press the panic button. The system immediately dials the preset ** and mobile phone for help.

There are many intelligent security systems, such as wireless routing, wireless cameras and so on.

There are a lot of intelligent security systems, such as some alarm systems, which belong to the kind of intelligent security systems, which can generally protect your own safety.

In terms of intelligent security systems, some such as some explosion-proof alarms.

Intelligent security perimeter alarm system: electronic fence, tension fence, laser radiation, vibrating optical fiber, etc.;

There are many literati who have skills to install the fire protection system, and you can see which one is the behavior.

The security industry is also one of the most promising artificial intelligence technologies and applications of the surveyed companies in the coming year. At this stage, China's smart security still mainly relies on 4G technology, but with the increasing number of security terminals, the requirements for network speed and network are higher. With the continuous progress of computer technology, and the discovery and progress of sensing technology, mathematical algorithms and other technologies, the field of computer vision is developing in the direction of artificial intelligence, providing better support for intelligent security.
