Anti-theft alarm development towards wireless network

The advantages of wireless anti-theft alarm highlight the application of anti-theft alarm has penetrated all walks of life, there are many no wonder many related technologies, cable alarm is still in development, wireless alarm has also risen, and there is a very good performance in The fiercely competitive alarm market has repeatedly made achievements, which also shows that the current anti-theft alarm market can be described as a vibrant and energetic vision. Of course, as a new technology, there are many different opinions when it comes out. This is also conceivable. Only with the gradual deepening, fully demonstrate his advantages before they can be understood and accepted by more consumers. Security products may not be completely deficient. If there is no progress, there will be no imitation. If wireless or wired devices are more suitable for the moment?

Easy to install: Everyone knows that, like some relatively large projects, when installing anti-theft alarms, the focal point lines are as many as several hundred, and sometimes they do not know where they are doing. Concern about the problem of the line, the movement is also very convenient, not only saves a lot of line costs, but also has a little flexibility for the maintenance.

Beautiful and generous: free from the limitations of the line, the layout will be more arbitrary, and the machine can not see the line, people feel more generous, and the surrounding environment can be the maximum integration. Convenient and affordable.

The application of the alarm network to popularize the basic operation of the Internet of Things constitutes a front-end “feeling”, a middle-end “password” and a back-end “counter”. Grasping these three links also clarifies the intangible line. This part of the "Biography" section also saw some new trends this year, laying the foundation for the integration of anti-theft alarms in the Internet of Things (IoT) system.

Networking has also become another main direction of alarm products. As alarm products that are closely linked with people's lives, many network products have also been introduced. The development of IPC has been relatively mature. This product is compatible with the dual protection of monitoring and alarm, and can achieve remote monitoring and storage through INTERNET, and realize the dream of the world. The development of IPC has also brought more end-users access to the alarm system. If alarm companies can further step on the alarm platform and information density, the future of IPC is very promising.

In order to comply with the pace of network development, TCP/IP products have become the direction of the alarm system. For example, IP security system introduced by some manufacturers this year adopts IP technology and takes the computer as the main body of operation. It can share the TCP/IP network with other devices, greatly reducing the installation cost, and detecting and automatically managing the alarm system on the last device through special software. Operating conditions greatly facilitate the management and use of users.

For the internationally renowned alarm brands, wirelessization and networking have been the focus of development in recent years. Internationally renowned companies have gradually increased the number of communication methods such as TCP/IP, GSM, and GPRS, and some have also supported mobile terminal control.

In the civilian sector, the emphasis on consumer psychological appeal is also reflected. At the 2011 Expo, many international products gave people a refreshing appearance. The elements used changed the industrial texture of traditional alarm products and began to take fashion. Art style. At the same time, the network terminal products require dazzling appearance and human culture design, and have very high requirements for the texture of wireless keyboards and remote controls. Seeing that some of the products introduced by foreign manufacturers are very mature and systematic, they all have a full set of wireless alarm accessories. The products include mainframes, various detectors, magnetic sensors, multi-function remote controllers, portable remote controllers, wireless keyboards, and wireless alarms. Wireless repeaters, wireless switches and a series of wireless products have truly created a complete wireless home package.

Anti-theft alarm technology constitutes 1, intrusion detector - a device that will be protected on-site intrusion information into an electronic signal and transmitted to the outside, commonly known as the probe, also known as the front end of the alarm device. Intrusion detectors are composed of sensors and signal processing components and are the key to the anti-theft alarm system. Sensors are the core components of the alarm detectors.

2. The signal transmission part, also known as the channel, is the channel through which the detector's electronic signals are transmitted externally. Currently, there are three main transmission methods, namely, three different transmission methods: dedicated line, borrowed line, and wireless.

Dedicated line transmission is the use of dedicated cables (including optical cable) equipment through the laying of a dedicated line network to form the transmission channel for alarm information. Its advantage is the specialization of the system, the information transmission is not easily interfered by external factors, and it is dedicated to the special line. Disadvantages are the large number of laying lines, high initial investment, and difficulties in expansion. They are not suitable for single-family single-family use. They must be controlled by the police or the police in the community or public security departments, and transmission lines are easily damaged. Therefore, such a system is only suitable for special projects.

Wireless transmission refers to connecting an intrusion detector to a wireless transmitter. In the event of an alarm, it will send a radio signal to the air. The wireless receiver generates an alarm when it receives the signal, notifying the personnel to handle it. The advantage is that it has strong anti-destructiveness, high transmission speed, and does not affect the appearance of the original decoration of the resident. In particular, the use of public wireless networks (such as telephone networks and broadband networks) has extremely advantageous conditions for information transmission. With the help of telecommunication networks, low investment can be achieved. It can also be used independently, which is unmatched by cable network transmission. The disadvantage is that if the battery is used for power supply, it may generate false alarms; it is susceptible to environmental limitations and transmission effects; it may be interfered by more powerful radio waves, lightning and other stray electric fields.

Borrowed line transmission refers to the use of telephone lines, power lines, cable television networks and other public lines as alarm signal transmission channels. The advantage is that it is easy to construct and does not require special wiring. The disadvantages are poor anti-destructive capability and being susceptible to interference.

3, anti-theft alarm controller, also known as the alarm host, it can change the intrusion detector's intrusion electronic signal into sound and light alarm signal and display and record, storage device, commonly used desktop, cabinet, box Type and wall-mounted several. Produce alarm sound, display alarm location, and store record alarm information is a basic function that the anti-theft alarm controller must have.
