The generalized problems fo home security alarm
At present, the past few years, the electronic security market is still slow progress, and security alarm market in China is mainly dominated by government and enterprises, the market for home security products unsatisfactory. Let us analyze the problem.
Alarm industry value to be recognized
The first is the value of the alarm industry has not been widespread recognition. Many industry insiders believe that the domestic alarm industry, like in the home field for real estate developers, engineering companies as a promotional selling point to obtain the tools of business interests, the market value of the industry as a whole are in a distorted form. The opening rate of the residential community alarm products, the low utilization rate, applicable to narrow, resulting in the majority of consumers do not feel the value of alarm products. This also led to consumers even if the face of alarm products still its very strange. Social identity, the burglar alarm products has lagged far behind belong to the same anti-technology industry, video surveillance, building intercom, access control, identification, and other products, which has become the negative premise of home security products marketing.
Secondly, home security products work unattended, high false alarm rate is very difficult to accept customers, regardless of the false alarm rate is caused due to any reason. This is the main reason for home security products can hardly be accepted by most families. Home security and enterprises and institutions, supermarkets, or residential area perimeter to prevent the conditions vary greatly, which has staff on duty, through the monitoring officer on duty view to determine the leakage of false positives, deal with the police intelligence. Need to use home alarm device deployment, and often at home unattended, if the occurrence of omission thieves committing the crime successfully, if the occurrence of false positives, the owner really police intelligence in the field is difficult to identify home, and the temerity to resort to guard, security, or 110 is likely to alarm. Home security phone alarm is a fortification in the unattended case, not only necessary, and users often make to ensure that no omissions, anti-alarm and anti-damage functions, false positives review function.
Detection for home security, tamper switch, broken glass, alarm, curtain infrared detectors, microwave detectors; the type of alarm SMS alarm, telephone alarm; signal transmission wireless networking and wired networking form; a system composed of a good solution to the false positive problem, greatly reduces it value, even if it is directional curtain + anti-pet detector designed specifically for home security or Dual Technology detectors (microwave and infrared or vibration and infrared) and only reduce the false alarm rate, and the price is still relatively high.
Alarm equipment failure caused by false alarms, and product design, production, testing, and maintenance are related. The type of fault damage failure and drift failure. Damage failure, including all performance failure and sudden failure. Such failure is usually caused by damage to the components or bad manufacturing process (such as Weld, etc.) resulting in Drift failure caused by the failure of the component parameters and supply voltage drift. We must raise the level of product design and technological level of reliability design, system design, are needed, such as redundant design, electromagnetic compatibility design, the design of the three defenses (moisture, salt spray, anti-fungal), drift reliability design. On this basis, improve the reliability of the manufacturing process, such as the rigorous screening of the components of the quality of aging; strict quality supervision and management of the production process to ensure product quality meets the requirements of relevant standards.
System false alarms annoying
Equipment selection is the key to the system design, while the alarm range of equipment types, but also have their own characteristics, the scope and limitations of the improper selection will lead to higher false alarms. Improper system design is also reflected in the Equipment installation location, installation angle, protective measures and system wiring. Front air conditioning, ventilation fans installation such as: passive infrared intrusion detector will cause false alarms of the system; outdoor active infrared detector if you do not make the proper sun protection (sun shade, the best protection), is bound to cause of false alarms of the system; alarm strong electric lines and power lines, lighting line line spacing of less than 1.5m, while that of anti-electromagnetic interference measures, the system is also easy to generate false alarms. Not strictly according to the design and construction; equipment installation for loose or improper inclination; joints Weld, burr, or shielding measures shall not be treated; poor adjustment of the sensitivity; construction does not meet the measurement requirements of the testing equipment will be improve the false alarm rate.
With particular attention to the false alarms caused by environmental noise interference.Due to false alarms caused by environmental noise interference generated by the alarm system in normal working condition, such as: passive infrared sensors, high fever, strong light and heat the adjacent air flow may produce false positives, when the relative temperature and body temperature close to you may occurrence of omission, but also less sensitive to carry glass and plate block the movement of human. Microwave detector is the use of Doppler frequency shift characteristics, monitoring of anti-region mobile body, some people enter the zone immediately to the police, but the anti-region of the animal, shaking the plants are likely to cause false positives. Microwave penetration of the walls and floor, if installed properly, the next-door neighbor's activities may also cause false positives. High-frequency sound can cause false alarms of the single-technology glass break detectors; ultrasonic source will cause the ultrasonic detector false alarms; rat infestation in the prevention area, pet walking around in the living room may cause false positives. This requires great attention to product design and installation. The micro-processing technology to the introduction of an alarm system to possess the necessary identification and the ability to think, to a certain extent determine the intruder or environmental noise disturbance caused by the alarm.
Any alarm, as long as the misrepresentation or omission, it will affect the credibility of its consumers reduce the sense of security. False positives, installation and product quality problems, the three mountains has been pressed in the alarm industry, the head of more than 10 years, became the alarm industry, "the intractable disease. Burglar alarm industry, the false positive problem is persistent, in which intelligent burglar alarm products "false positives" problem is particularly acute, also aroused the concern of the whole society of false positives.Reduce and eliminate "false positives", which is a severe test of current anti-theft alarm industry, it is imperative.
Alarm system and video surveillance systems integration, development trends of the video review of alarm monitoring integration, video surveillance review quickly and accurately make judgments, to avoid waste of public order resources. Video review to confirm the alarm information is a fundamental solution to the method of false positive is a good question, this is also a way out of the home security systems.
Use the family computer hardware, intelligent recognition of the detection signal processing software into the computer, you can now host the alarm simplified detection of the signal receiver, through the integration of alarm host and home computers, intelligent recognition intrusion alarm Internet technology and residential property management center can also be used to build throughout the day keeper of a wide range of alarm processing center, by the alarm processing center, residential security alarm residential in which local police for help, can greatly improve the timeliness of an alarm. This program is also a promising
Omission is worried about another aspect of the user. Failure to report the reason is more complex, in addition to the product itself may be due to leakage insurance, other causes may also result in underreporting. Such as surface mounted with concealed alarm is also a problem of product promotion. Electronic products for video surveillance and security alarm detectors are almost always of enormous mounted not only inevitable in the installation procedure and form to the perpetrators of the destruction of the target and returned to the thieves to create anti-alarm conditions. Last century, Kaifeng Museum of the Northern Song Dynasty relics of identity theft, thieves using anti-alarm means the crime of successful cases. With the development of science and technology, crime intelligence, complex. The merits of a considerable part of the install home security systems is not for the thieves, but anti-alarm committing the crime, because the product due to technical omissions. Choice of Shuangjian function, broken glass, such as displacement, vibration alarm detectors, the limitations of its physical properties can also be directly or indirectly, anti-alarm crime.
Security products on-demand positioning
Police do not report, such as passive infrared detectors fortified rooms, thieves available glass, plates and other objects carry block body infrared radiation to enter the zone to complete the anti-alarm crime.
Security systems for customer service, we must first consider the practical needs of users, affordability, user awareness and customs, more suitable varieties of home security products is relatively small also contributed to the promotion difficult a problem.
Security Project's operating environment vary widely, and also a variety of techniques to achieve the same purpose can be, we must first economical and practical, not the more advanced the technology the better, more expensive the better. Current technology, there is no comparative sense, the best intrusion detection products can only choose the most suitable for the needs of intrusion detection products. Which uses need to include the subjective needs of the user to prevent grade and the actual use of the integrated environment has two meanings; accurate scene depth design, improper installation, accurate debugging is very needed.
Applications on the market will move forward towards a more refined direction , the introduction of different products for different markets. Smart home, the increasing popularity brought about changes in market demand and promote the development of the burglar alarm industry, also rising demand for home burglar alarm, by a single alarm dialer into intelligent control platform with multiple modules and value-added services burglar alarm products will be more competitive.
