Why does the engineering company not plan to prevent theft? In addition to users’ limited knowledge of safety equipment, once funding is provided, the priority is to install a monitoring system capable of “seeing images†in order to “restâ€. The biggest key is that users do not trust the accuracy of alarm reporting. degree! Therefore, if you can master a good way to reduce the false alarm rate, the project owner may be able to take the anti-theft device into the project plan and create a higher profit for his own case; even facing the owner's designated to install anti-theft devices, your competition Strength will be higher than their peers.
In view of the fact that many contractors are eager to learn about anti-theft installation technology, they cannot find a suitable pipeline. A&S invited experts to share it with everyone this time. Before an anti-theft device can be properly installed, an engineering company should have several important ideas.
Partitioning
First of all, we must first establish the concept of anti-theft sub-regions. In general, outdoor anti-theft is divided into three levels, from the outside to the inside is the perimeter fence, the middle of the protective area, the building body periphery (not yet into the room), in order to represent different levels of intrusion (see Figure 1), once the thieves break through The first two lines of defense came to the third floor, which also showed that the thief will soon invade the house. It depends on the last line of defense. From this we can see that doing a good job at all levels is an important start for theft prevention.
Multivariate
Liu Qinghuang, deputy general manager of Quanxin Enterprise, said that the anti-theft is not absolute, it must be divided into multiple levels of protection, but also with a variety of equipment in order to achieve the best anti-theft effect.
For example, the first layer of the periphery uses a physical fence or an infrared detector, and as for the middle area, a stable outdoor infrared detector may be used, and the third layer of the building body may use doors and windows. Special detectors and other equipment prevent thieves from intruding.
Based on local conditions
In addition, Qiu Wenhui, general manager of Qijun Enterprise, said that the features of "small amount of diversification" of anti-theft devices are even more obvious. Each device has its own characteristics, blind spots and installation requirements. It must be adapted to local conditions when building equipment. through". Engineers need to solve different equipment characteristics, which areas are suitable for use, such as direct-beam infrared beam, so it is particularly suitable for closed protection, large area (long distance), and square layout of the external protection.
However, if the perimeter of the built environment belongs to hills or downhill terrain (different heights at both ends), it must be considered. Zhang Guangyu, the person in charge of Shanglin’s business, said that if there is a high level of difference, the infrared detector will have a high and low mounting height between the light emitting device and the receiving device, causing the beam to be misaligned and the focusing to be inaccurate. At this time, the physical fence will not be affected, because the current use of steel cable structure, with a certain degree of flexibility, and if due to terrain, and the emergence of elastic fatigue, the mechanics directly adjust the tightness of both ends of the screw.
Therefore, it may also be considered to change the physical fence as a protection. If users worry about aesthetic problems, they can also plant trees at the edge of the fence, not only beautify the environment, but also have the effect of concealing equipment. In addition, when installing infrared products, it is also necessary to pay attention to the angle of irradiation throughout the year to avoid false alarms.
For peripheral areas with irregular edges, the latest Intelligent Image Analysis System (IVS) can be considered to define irregular virtual fences. Liu Qinghuang said that recently there has been a gradual increase in the tendency of video surveillance products to replace anti-theft devices. However, the establishment of IVS also requires special attention to changes in the environment and light sources, and the camera's resolution and device angle should be particularly careful, otherwise it will easily lead to false positives, and its stability needs to be improved.
Demand
Everyone knows the need to understand the best product.
However, some suppliers indicated that they encountered many engineering companies who refused to disclose the environment and location of product applications because suppliers were afraid of rushing into business. As a result, suppliers could not give more professional selection advice.
In addition, suppliers often encounter contractors who do not understand the wiring and do not understand the installation technology. They will temporarily purchase products and install them on-site. Because they do not have the time to learn the relevant knowledge, they will install the direct supplier DEMO. Wiring, the entire direct to take home, according to the local method of steel making, the effect of its construction, so that the vendor has pinched a cold sweat, but also worried about the future will affect the anti-theft device construction effect, lose customer trust.
Cai Mingxun said that the principle of anti-theft devices is not difficult, but still need to learn professional technology, suppliers are happy to provide such teaching, to help engineering companies avoid future huge maintenance costs. The contractor should also clarify the usage description and let the supplier help you choose the best product.
