Wireless alarm detector market application is relatively blank

The time for wireless alarm detector technology to appear in China is not short, but its market application is relatively blank. Nowadays, as the sensitivity, reliability, stability, and wireless communication technology of the detectors are maturing, the industry's manufacturers gradually see the dawn of applications. From the sales data of burglar alarm manufacturers last year, the market growth of wireless detectors has guaranteed certain stability. According to Yu Gang, general manager of Shenzhen Huaji Electronic Systems Co., Ltd., “With the development of wireless single-channel detectors from analog to digital technology, as well as the gradual reduction in the false alarm rate of the probes and the increase in sensitivity, we have seen the sales figures from last year. The growth rate of wireless detectors and the proportion of wired detectors are synchronized."

Compared to wired detectors, the advantages of wireless detectors are obvious. In addition to satisfying the aesthetic needs of home users for interior decoration, it is more important not to use wiring, easy installation, simple construction, and to reduce construction costs. Based on these advantages, the application of wireless detectors is irreplaceable, and it occupies a certain market share, even in some places, such as in coal mines, exhibition halls and other difficult to wiring or moving targets must use wireless detectors. In addition, with the increase in the cost of labor in recent years, the use of wireless detectors has become a more economical choice, and also provides a certain space for the application of wireless alarm detectors.

In terms of the current development of wireless detectors, manufacturers need not only make breakthroughs in wireless detector technology, but also need to identify the different needs of different users in order to promote the growth of the wireless detector market.

Boiling up again, breaking the calm of technology In recent years, the anti-theft alarm system has maintained a stable development trend, in which the technological innovation of the detector provides the foundation for its development. Manufacturers have made progress in the sensitivity, reliability, and accuracy of detectors, and some functions have been realized, such as infrared microwave dual-detection, automatic inspection equipment operation, and two-way communication.

It is understood that the current application is still more wireless single probe, but in order to ensure the accuracy of the detection target and alarm, there have been wireless dual-probe detectors on the market. According to Li Jia, deputy general manager of Shenzhen Elite Long Security Equipment Co., Ltd., the detector is affected by room temperature, and the detection distance can reach a very long distance at normal room temperature installation, but if it is higher than this temperature, the sensitivity will be greatly reduced. , resulting in shortened detection distance. The Wireless Shuangjian detector can realize the double identification of the target object by means of infrared and microwave, which can make up for the defect that the infrared detection is affected by the temperature and the detection distance is shortened. However, Yu Gang of Shenzhen Huaji believes that the current wireless infrared double-detection technology will generate greater power consumption, and it will encounter greater challenges in terms of power supply, which requires manufacturers to make trade-offs between the two.

Wireless two-way detectors are also a future development direction. Dai Mengyu, an engineer at Shenzhen Mei'an Technology Co., Ltd. mentioned that since the detectors are in working condition for 24 hours, whether the host is in the armed state or not, the detector will send a wireless alarm signal to the host once it is triggered, which greatly increases the The loss of the battery. If the detector is made into a wireless two-way communication, only when the host arming instruction is received, the work is started, and usually it is in the micro-power standby state, which effectively reduces the probability of the alarm triggered by the detector, thereby achieving energy saving. The effect, at the same time, the host can also send an arming confirmation signal to the remote control to facilitate the user to understand the system operating status. For example, ZigBee-driven two-way communication wave has already been used in the same way as wired products, but at the same time its power consumption and cost are high. At present, Israeli manufacturer RISCO has launched a wireless detection system for two-way communication.

In addition, due to the influence of natural environment or human factors, the detector may be damaged or stolen. In order to ensure the normal operation of the wireless detector, some manufacturers add a regular inspection function to the detector. "That is, every time the detector's probe is lost, failure-free, damage, and channel blockage are detected," said Zhang Yuxi, technical manager of RISCO Group's Shanghai office. According to reports, most of the wireless detectors of Israeli suppliers have such a periodic polling function to detect all wireless communication devices, but most of the domestic products do not have this function.

At the same time, the development of wireless technology also provides good support for wireless detectors. The 4G experiments from 2G and 3G to the current mobile have started, and the stability of the wireless network (reduced packet loss, serial line and other issues) has been greatly improved, and its supporting equipment, such as wireless keyboards, have matured. On the other hand, manufacturers The security of wireless transmission has been enhanced through rolling encryption.

In response to different needs, market positioning has its own focus. In fact, the market for wireless alarm detectors is diversified. Unlike DVRs, a product can compete with the world and have different needs for different markets and application environments. At the same time, there are also differences in technologies at home and abroad, such as the sensitivity and accuracy of wireless detectors, so the market for domestic and foreign brands is also different.

At present, domestic manufacturers of alarm detectors are mainly concentrated in southern China, especially in Fujian and Shenzhen. Most of them belong to small-scale manufacturers. They do not have the core R&D capabilities, and they are relatively good companies in terms of detectors or hosts. Such as Horn, Mei'an, Jinglong, Xinwei, Kelixin, etc., in addition to promoting their own brands, but also OEM production is sold to countries in Asia, Africa and Latin America. It is understood that the domestic product is easy to operate, affordable, and can basically meet the needs of ordinary users, mainly for the consumer DIY market, or home improvement, residential market. And some foreign manufacturers, such as Honeywell, Bosch, RISCO (including its EL3000), Cologne, Otis, and Senville, etc., sell their products in the domestic market mainly for professional and powerful alarm operation service markets. The market has strict technical requirements and is not so sensitive to prices.

In the home consumer market, promoting the scale of wireless detector applications, as mentioned above, home users in buildings or communities do not have high requirements for wireless detector professional technology. They are more concerned about whether it will affect the interior aesthetics, such as the decoration of Whether the wall will be worn or not will affect the interior decoration. In this market, the appearance refinement and miniaturization of wireless detectors are non-negligible factors.

According to Yu Gang of Huaji, the project is directly pushed to the home market by the engineering firm through cooperation with real estate and property management channels. Wireless detectors are installed directly in the room and used free of charge for households, and some are used by electronic supermarkets. The retail approach is extended to home users.

It is understood that the community users install the detectors, and the actual effect of the use is generally less than 10%. This means that if the alarm system generates alarms, the need for service personnel to handle them in time is not the focus of this market, but more attention is paid to wireless detectors. Convenience and aesthetics, and sensitive to price. Under this premise, community users tend to choose domestic wireless detector products. Since the current market is far from being satisfied, it is worth looking forward to entering the DIY and home markets in the future. It is understood that in the wireless part of the home consumer market, the domestic share of wireless detector products accounted for more than 90%.

In addition, if you want to sell to the home market, manufacturers need to control the cost and price. Compared with professional industrial markets, the consumer market is relatively large and users are more sensitive to costs, so there must be differences in cost control.

If wireless detectors are to be used in the DIY market, they will enter electronic supermarkets. This means that users can install and debug their own wireless detectors without having to go through the engineering service provider's or operator's on-site service. The complexity of operation, sensor angle debugging and other operations are of great significance for opening the consumer market. Li Jia, the essence of Long, believes that wireless alarm systems need to be specifically designed for the consumer market.

The alarm operation service market opens up the application of the service market to the consumer market, and the alarm operation service market demands higher wireless detectors. "Alarm operations service providers need to comprehensively consider the product quality and the overall cost of operation and maintenance services, because this is related to the operation and maintenance of the later period," Yu Gang emphasized.

Alarm service providers have high demands on the battery life and false positives of the wireless detectors. As we all know, false positives, false negatives, and replacement of batteries all increase unnecessary manpower and material maintenance costs. Therefore, if wireless detectors can reduce power consumption and battery life is longer, they are more practical and economical for users and alarm operators. In addition, the alarm operators hope that the wireless detectors can work for 6-7 years.

Therefore, the alarm operation service provider usually requires less false positives for the detector, smaller second maintenance, longer service life, and less relative price sensitivity. This market currently has many applications in Israel and Europe and the United States. Wireless products such as Israel are more popular with high-end homes, villas, and apartments facing alarm service operations.

It is understood that currently most of the alarm operation service market uses wired detectors, and only a small part use wireless detectors. The original Shanghai security service company Zhu Mingchu mentioned that 98% of our alarm service centers use foreign wired detectors. The detector only occupies a small part.

It is worth mentioning that the current alarm operation service company still focuses on the traditional telephone alarm. If the wireless detector is to be replaced, the design of the entire system needs to be changed. With the reduction of alarm operation service thresholds, companies can independently plan their service scale, equipment, and personnel. Mei An's Dai Mengyu introduced that some anti-theft alarm manufacturers and engineering companies have begun to enter the field of security services. This is also a niche for the use of wireless detectors. Its main customers are shops, households in the county's urban areas.

Select wireless detectors, should have the correct perception Because the main market for wireless detectors is for the general public, so these non-professional users have the correct knowledge and choose essential products, it is necessary. Among them, the user's main focus on wireless detectors focuses on the following directions.

The first is power supply and low power consumption. The wireless alarm detector is based on the operation of the battery, so the power supply is very important for wireless detectors. If the battery is to be replaced within a few months, it will undoubtedly increase the workload of the operating service provider or the engineering company. At present, the battery power supply capacity of Israeli manufacturers' products can generally reach 2-5 years, and the power consumption can be reduced to a few microamps. The domestic wireless alarm detectors can supply power for up to two years. For example, Congwen can now achieve 20 microamperes. Below, the battery life is extended.

The accuracy of wireless detectors is also of concern, including the detector's sensitivity, detection range, detection range and detection area, and environmental adaptability. Zhu Mingchu of the original Shanghai Security Service Company emphasized that since the sensitivity is related to the problem of false alarms, the wireless detectors must not be ignored in each detection angle range, in addition to meeting the objectives required by the project. For example, the detector can reach 8 meters in the middle distance, but the two sides may not reach the same degree; even if the ambient temperature changes, it must also meet the needs of users.

Once again, the wireless detector communicates with the control panel by transmitting wireless signals in the air. How to ensure the smooth communication of the signal communication and avoid interference from external light, air currents, small animals, obstructions, and other objective environments or static magnetic fields, avoiding The channel is occupied and cannot be ignored either. “In order to avoid signal channel occupancy and various interferences, we do not recommend the use of wireless detectors with longer transmission distances, such as a transmission distance of over a kilometer, which is not only impractical, but also causes signal interference due to excessive transmission power, or Missing reports due to the occupancy of signal channels.” Yu Gang of Huaji Electronics Co., Ltd. mentioned. It can be seen that the wireless detector's transmit power is also limited, and the state requires wireless detectors to transmit power within milliwatts. This requires the user/engineer to use the environment in advance for evaluation.

On the other hand, the wireless detector's transmission distance is not as long as possible. At present, industry technology can generally reach about 200 meters under certain circumstances, but there are also some wireless detectors that can reach 1 km or even 10 km. In this regard, Yu Gang of Huaji said that longer transmission distances require more transmission power. And it will inevitably affect the transmission of other wireless signals in the same range.

As for costs, users can basically accept the cost of wireless alarm systems. Although wireless receivers and transmitters will be added, the wiring materials and labor costs can be saved.

Future development trend: According to the segmented market to provide comprehensive products, the market segmentation will be the main trend of the future development of wireless alarm detectors, combined with different environments, locations will use different technology detector products. As Long Lijia said, "When we are planning our product market, we should relax our horizons. We should not only focus on one product, ignore other technological advances, and create new products and new products through cross-cutting." The market can be broadened through technological advancements and integrated applications."

In fact, wireless and wired detectors can be used as backups in some locations. Instead of comparing the advantages and disadvantages of wireless and wired detectors, it is better to choose the applicable technology according to different markets. For example, the financial industry, military industry, etc. are pursuing stability. Wireless and wired alarms can be used at the same time. When a channel is blocked, another channel is used as a backup.

Another concern is that under the concept of the Internet of Things, wireless detectors are part of the IoT front-end sensor. The entire wireless alarm system is no longer just a stand-alone system, but is integrated into one of the Internet of Things plans. Subsystems, which will promote the rapid development of wireless detectors.
