Today's burglar alarm system has made great progress. Regardless of the quality of appearance or function, the requirements for functions have become even greater.
Anti-theft alarm technology analysis detector determines the advantages of anti-theft alarm system
At present, the burglar alarm system is mainly used for intrusion detection, that is, through the installation of various types of detectors (such as active and passive infrared, microwave, door and window reed switches, emergency buttons, glass break detectors, etc.), according to pre-set rules , detecting whether the protected area has abnormal intrusion; when abnormal intrusion is found, the alarm controller performs warning of voice and light and displays the alarm point area at the same time. The networked system will also send alarm information through the mobile phone and tablet. Pads, local telephone lines, IP networks, or wireless telecommunication networks, notify subscribers or monitoring management centers. Among the detectors that can be connected in the anti-theft alarm system, infrared is one of the most important detection methods at present. The demand for multiple detection applications is constantly deriving, and the building environment is increasingly complex. Today, in addition to installation technology, the development of detection technology in burglar alarm systems has become an indicator of whether the system has an advantage. We can examine the application and development of the next few detection technologies.
The first and most popular application is infrared anti-theft detectors. Infrared anti-theft detectors are classified into active (AIR, also known as “shootingâ€) and passive (PIR, also known as “thermal sensorâ€). Active infrared light is often used for perimeter protection because it has a light emitter that emits a light beam automatically, blocking it and reporting it incorrectly, and the light beam is straight. As for passive infrared light, it detects infrared radiation of about 10-12 μm that the human body emits. Sensing the alarm, but because in the normal state, the outdoor temperature difference changes greatly, heat source interference and disturbance, so most of the passive infrared detectors can only be used for indoor or specific area space use. In addition to infrared detectors related to the quality of anti-theft alarm detection system has the following ten false positive factors, must be carefully considered in the application of technology, the main reason for the 10 major infrared detector false positives:.
1. The anti-interference ability of RFI & EMI radio frequency is poor, causing adjacent-frequency interference.
2. Inaccurate judgment of personnel invasion behavior.
3. Affected by ambient temperature and strong light.
4. The alarm host and detector caused duplicate coding due to multiple configurations.
5. The shape of the translucent cover is poorly designed.
6. Internal light component design angle error.
7. Infrared detector installation method is not good.
8. Multiple detection technology application errors cause mutual interference.
9. Poorly reported product manufacturing process and operating errors.
10. Detection range, range, temperature compensation, incorrect sensitivity settings, or poor collocation.
Sensitivity and false alarm rate have always been the contradictions that burglar alarm products must face because the sensitivity of products increases, and the false alarm rate often rises. Therefore, many manufacturers have already improved this. It can be seen from the above that infrared detectors may be misreported, and most of them are related to the product's design and manufacturing capabilities. Therefore, the selection of the product's performance is the first threshold to reduce the false alarm rate.
Anti-theft alarm host and control panel technology upgrade
After many years of development, the anti-theft alarm system has entered a mature period. The miniaturization and refinement of the product's appearance have been unable to continue to meet the needs of customers. The diversity of functions and the stability of performance have attracted more and more attention. For example, intrusion detection requires rapid response to instant intrusion events, or it may cause major losses. Therefore, excellent anti-theft alarm products should seek balance in both performance and reliability. In detection technology, "infrared + XX" dual or triple detection technology can be used to minimize the false alarm rate. In addition, if the host is equipped with an embedded MCU or a micro-processing CPU technology, the function of the anti-theft alarm host can be upgraded to a more diverse interface. On the control panel, from the point of view of this test product, it is refined. Simplified control operations and control of moving the interface remotely are inevitable. With different access control interfaces, the control panel is no longer a rigid keyboard. The burglar alarm control panel and the control panel have also been greatly improved in the mechanism of preventing intrusion and vandalism. We can see the design of the combination lock cover plate and the structure of the exterior material structure that emphasizes the resistance to violence and weathering. All this has been highlighted. The overall anti-theft alarm system technology improvements.
Anti-theft alarm system development humane
As people's living standards have greatly increased, in real life, the technology of anti-theft alarm systems can also be applied to provide personalized medical alarm services. Existing operators have launched a remote medical care response system solution in response to the development trend of aging in China. Through the features of the LCD screen, keys, and call keys of the anti-theft alarm panel, after the user presses a key, he or she can directly communicate with the security service center or relatives without using a telephone. The system can also instantly discover information such as user falls, activities, etc., and has a variety of event voice reminders such as regular medication reminders. In addition, the latest anti-theft alarm host system can also be equipped with a variety of Bluetooth medical equipment such as an electrocardiogram monitor, a blood glucose meter, a blood pressure monitor, a weight scale, and the like, which can be used to instantly detect the user's blood glucose and electrocardiogram. Such physiological conditions, and through the alarm control host, the user's physiological status (electrocardiogram, blood glucose, blood pressure) information transmitted to the remote medical staff for home care.
Anti-theft alarm system integration and application
Integration is a major development trend in security systems, and burglar alarm systems are no exception. In fact, the integration of anti-theft alarm systems with other security subsystems such as image surveillance and access control systems is not new. In recent years, as it has gradually expanded its applications to residential and community communities, it has also begun to integrate smart homes, but these are only It is the simplest and most basic integration. In addition, it is also possible to perform linkage between burglar alarm and image monitoring. At present, only the output interface of the front-end detector is connected by hardware and the alarm-alarm input interface of the image monitoring is connected. When an abnormal situation occurs, The preset linkage mode performs image alarm linkage to realize video playback and hard disk recording. Another example is the integration of information with software platforms. In addition to hardware integration, software integration is the focus of integration between various anti-theft alarm subsystems. In the integration of various systems, the key point at present is how to solve the interaction and processing of information between systems.
In the meantime, the latest anti-theft alarm integration requirements must achieve multiple alarm network coexistence methods. Anti-theft alarm network has an easily confusing meaning, that is, the alarm controller and the control center network, with the alarm detector and controller Networking, confused. In fact, the alarm networking method includes both wired and wireless, such as connection* or wireless GSM phone notification, and the connection between the alarm detector and the control host, and the wireless is dedicated wireless, such as infrared or Zigbee, etc., not the telecom operators. Wireless platform provided. In terms of importance, the networking of alarm controllers and control centers is the key to system integration. In recent years, with the prevalence of IP networks, many alarm controller manufacturers have begun to use wired or wireless IP network networking, but actually see the networking applications due to the closed environment of the use of TCP/IP. The way the network is currently used has not grown significantly.
Anti-theft alarm service development direction
"According to its requirements" - to meet the different needs of different types of service objects Different types of service users' security needs vary widely, although the alarm service can not be all-embracing, but in mainstream applications, should meet the needs of its risk prevention, do Timely, reliable, accurate and effective.
The key to the alarm service lies in whether the alarm service can meet the service subject's expected disposal subject, such as the police, and “timely†arrives at the crime scene to handle the request.
* The police required that the police be required to arrive at the scene within 10 minutes of the city within 5 minutes of the urban area. According to statistics, if the police arrive at the scene one to three minutes after the alarm, the catch rate is generally 60% to 70%. If it arrives at the scene in about 5 minutes, the catch rate is only 20% to 30%.
If the alarm service takes a long time in its own alarm, nuclear, and forwarding links, even if it provides the police with accurate alarm information, it will not help or cause a certain loss to the customer. This will lose the significance of the alarm. . Therefore, in order to adapt to the policing mechanism of the police, the alarm service must have an effective response time. Now that the alarm service is available, when an on-site user site alarm occurs, the on-site image and alarm information can reach the 110-station alarm station and the alarm service center duty station within 2 seconds. The alarm service center duty station nuclear alarm time can be within 30 seconds. Clock inside. Forwarding time can be within 2 seconds. To achieve this level of time, it will win valuable time for the police to solve cases on the spot. The alarm service should adopt the means of video-nuclear-alarm. It is impossible to rely solely on the telephone nuclear police or artificially go to the scene of nuclear police.
For families and individuals, the first concern in security is life safety protection, physical health protection, followed by loss of property robberies, equipment damage and so on. Since domestic citizens cannot hold weapons and control tools in accordance with the law, they have almost no resistance when faced with vicious personal abuse. They can only rely on the police completely and rely on the police to arrive at the scene in the shortest possible time to ensure personal and property protection. Security. Therefore, the alarm service should ensure that the demand for such alarm assistance arrives at the police within the shortest response time. However, when burglary occurs during the absence of a customer, what the customer expects at this time becomes how to protect the property from loss. As long as the property is not compromised, it will not matter to the customer whether he can catch the thief. Therefore, what the alarm service should do at this time is how to use technology to intimidate criminals and stop the crime on the spot.
For the needs of different types of customers, there should be corresponding alarm service items and non-policy rescue services stipulated in the contract. Such as assisting customers to remotely or on-site to lock the door, discourage non-business entry personnel, reminding abnormal operators to accept abnormal service procedures, targeted to meet the different needs of different types of service objects.
“Approaching the distanceâ€â€”The modernization, networking and localization of modern alarm services, and professional alarm services rely on information technology systems to provide alarm information. The core of the alarm service is to establish a fast channel between users and/or rescue agencies. To solve the problem of rapid contact between customers and * or rescue agencies.
From the perspective of the development of the alarm service industry and the status quo, the alarm service is not limited to local alarms. It is a remote, alarming, and cross-city police service. On the one hand, the alarm service is based on information services, meets demands with modern new technologies, new formats and new services, and features high-tech, networking, and global sharing. On the other hand, the alarm service must complete the agreement with the customer and its disposal must be performed locally. This "distant" and "near" constitute two aspects that are indispensable to the modern alarm service industry. It is necessary to support the nationwide service scope of the alarm service with the information system and networking of the technical system. At the same time, it must also provide specific integrated services to the localization, specialization, and timeliness of the rescue implementation. The cross-regional large-scale remote monitoring and alarm system forms an effective combination with the local monitoring system and security and rescue services. It will also be a development direction of the alarm service in the future.
