The advantages and disadvantages of wireless burglar alarm

After the emergence of the cable, wireless took advantage of the latter's identity to share more than half of the country's advantage. In recent years, wireless technology has risen in the security field and ushered in the golden stage of development. Because no special wiring is required, the installation is quick and easy, and the stability of the technology is enhanced. The wireless alarm technology has also been greatly improved in security alarms and the application rate of the smart home market. Wired alarms are still booming, wireless alarms are unwilling to be lonely, and the constant success of the alarming market has made new achievements. Although wireless alarms have brought us more convenience, some of the drawbacks of wireless devices have also plagued us as we have applied them. So which of wireless and wired devices is more suitable for us?

Wireless alarms: These are practical and similar to other wireless devices. Wireless alarm applications are more focused on application convenience, aesthetics, or device operation.

Installation Convenience Since it is wireless monitoring, the convenience of construction can be said to be the biggest feature of all wireless monitoring devices. The use of radio wave transmission wireless alarm devices not only saves a lot of line costs, but also a very large savings for the construction equipment during the installation process.

In addition, in the selection of the equipment work site, to a certain extent, it can also get rid of the restrictions of the transmission line more and become more flexible.

The appearance of the equipment in the application of wireless alarm equipment not only has great convenience in construction, but at the same time, it may also be more free from the restrictions of the mass of the equipment and become more arbitrary in the design or location of the equipment. . Especially in some home environments, or relatively high-grade occasions, the degree of integration with the surrounding environment is often one of the most important needs of these users. The freer features of wireless monitoring may satisfy more requirements that are hard to meet for some cable monitoring devices, such as design or construction.

More economical and convenient Although in some remote wireless alarm devices, their control contact method still uses the mobile phone GSM communication network to complete our work. However, with the application of some new technologies, many wireless alarm devices are also using infrared probes to receive the corresponding signals, and send them to the corresponding alarm control host via wireless, if we want to call the control panel. A good integration with the alarm center will not only save the trouble and expense of cable laying cables, but also save the communication costs incurred each time with the alarm center. It can be said that it is a result of more than one kill.

In addition, in the wireless transmission mode, without fixed line restrictions, we can also achieve a more comfortable choice for the picking center, instead of having to bind to a certain work site because of the fixed line, but according to our needs Selecting the best alarm information receiving terminal makes our alarm work more efficient and management more flexible.

Wireless alarm: These do not speak of some of the advantages of wireless alarm, let's talk about some aspects of wireless alarm technology that are still immature.

Anti-jamming capability If you talk about the shortcomings of wireless alarm devices, I am afraid that many readers are the first to think about the defects in the anti-jamming capability. Yes, compared to wired networks, wireless networks are relatively open to the transmission and reception of signals. Especially in places where there are a lot of radio waves, electromagnetic signals such as mobile phones and appliances will inadvertently become interference sources that affect the normal operation of the equipment. Therefore, in the protection and identification of information, it is obviously more complicated than wired network equipment.

What we need to pay more attention to is that for burglar alarm devices, long-term interference is very easy to cause the system to fail, so this is also some of the main methods that some lawbreakers respond to burglar alarms. Although some devices have some ability to recognize this kind of human interference. However, this simple passive defense cannot completely change the influence of interference on the safety of the equipment.

The design of the structure For most of the current wired alarm devices, basically the mainframe and the keyboard are used to complete the assembly of the alarm device. Under normal circumstances, the wired alarm device uses a metal chassis, and has a strict tamper-proof function, even if the exposed keyboard has a certain amount of anti-destruction capabilities. This can basically avoid the momentary embarrassing situation when the equipment is destroyed in the outside world.

For the wireless device, the keyboard and the alarm host are mostly combined, and the shell security of many devices is not as strong as the wired device, so this also increases the risk of the wireless device in normal operation.

The battery life is based on the characteristics that the alarm equipment requires long working hours and high coherence. In the configuration of the wired equipment power supply, the higher storage capacity and the larger battery are generally used as our power supply. For the wireless alarm device, because of its more random appearance, and often using relatively small bodies, the application of the battery is often limited to some small batteries such as the 5th battery or the 7th battery. Application. Under such circumstances, the battery life of the device sometimes decreases with the increase of the usage time.

Trigger Delay and Transmission Limit Nowadays, many devices will set the trigger delay on the wireless device to avoid excessive power consumption or prevent the occurrence of false alarms. Although such delay may be in our energy saving. On the achievement of certain results, but if we face a security threat in the monitoring environment, the performance of the device may also be greatly reduced with the delay of the device.

In addition, some wireless hosts have a relatively weak networking capability, which is often not a limitation of the compatibility of a custom transmission protocol or compatibility. Such a device will undoubtedly cause limitations in the transmission of information and affect the quality of our security alarms.

Through some of the above analysis, we also have a certain understanding of the wireless anti-theft alarm device. In fact, to sum up, it is not difficult to find that the main feature of wireless alarm devices is the ease of use. The degree of humanization in applications may be higher than that of wired devices. However, in the face of current technical features, there are still A lot of performance hard injuries have not been fully digested. This has a very big impact on the application of wireless alarms.

Therefore, for the application of wireless alarm, the author thinks that its destination should be a more convenient and beautiful civil-grade product. And if we have higher requirements on the performance of alarm equipment, the more mature and more reliable wired equipment is still the best choice for our current application.
