Security intelligent product selection five principles

First, the status quo of China's security intelligence Although the market is "loving" technology, but the application of intelligent video analysis technology in China is not easy. Some of the world's professional IVS research manufacturers, such as the United States, ObjectVideo, Vidient; Israel's NICE, Mate, IOImage; Australia's IOmniscient and so on. These manufacturers have entered the Chinese market one after another, causing foreign companies to monopolize the domestic market of intelligent video analysis. In the end, because of the difference between its technology and China's national conditions, it cannot really penetrate the Chinese market. However, most of the domestic smart video analytics manufacturers can identify the behavioral features that are limited to specific situations. For example, target tracking, cross-border, counting, target loss, object left, etc., are mainly used in relatively fixed application scenarios such as detention centers, prisons, museums, warehouses, plant sites, and subway stations, and in monitoring environments targeting the social level, due to monitoring The complexity and variability of the scenarios have led to a significant reduction in the stability of the monitoring. The intelligent monitoring products that use the accuracy of the alarm events as the evaluation criteria have also highlighted their application limitations. Therefore, the intelligent video analysis technology is in an appalling position. Embarrassingly, if we investigate where the inflection point of intelligentized large-scale application is, it should be said that in addition to the inherent advantages of the previous analysis of its own technology, it is necessary to solve the following bottleneck problems, perhaps, sand and sand, security, intelligent The big explosion is just around the corner.

Can not completely eliminate the impact of false positives For example, the background modeling technology in moving target recognition, while controlling the number of missed reports, can not completely remove false positives. In the perimeter prevention products with target recognition as the basis of technology, the number of false positives has always been a major indicator reflecting the pros and cons of the product. The number of false positives is caused by the difference between the background model and actual use. The stronger the model's adaptability, the less false positives are caused and the higher the required technology is. There are many factors that affect the establishment of the background model.

Another example is the empty asphalt road and the wall with trees on the edge. The images taken by a 6-meter-high camera and a 2-meter-high camera require different background models. The day and night conditions require different models. At present, the industry has not yet developed a background model that can cover all use cases, nor can it completely solve the effects of random events, such as false alarms caused by lights in the dark environment; secondly, it does not have the ability to judge behaviors. . For example, the perimeter intrusion prevention and the regional intrusion function of behavior analysis in the machine can find the target of the activity, and can use the technical means to extract the target (such as the human body) desired by the user. But further, what is the motive of the intruder, whether it is an occasional pass or a deliberate intrusion, whether it intends to visit the guarded area, which cannot be identified by machines?

Feature recognition technology has high requirements for images. For feature-based analysis techniques, the requirements for images are relatively high. In addition to the definition of the screen itself, it is also necessary to clearly display the characteristics of the target object. The current computer's recognition ability is much lower than human's ability to recognize the object's features. Different lighting conditions and shooting angles will change the characteristics seen by the computer. Finally, the processing power of the CPU is still a bottleneck. To meet the actual complex application environment, more complex algorithms are needed, which brings a huge amount of calculations. Currently, the capabilities of DSP chips are limited, and they cannot meet the needs of some complex algorithms. Therefore, it is difficult to develop embedded products with corresponding advanced functions, which also increases the difficulty of construction and the resistance of practical promotion of many products.

Second, the principle of intelligent security product selection After winning the bid, the security engineering firm should determine what kind of intelligent security monitoring system or product. The purchase of intelligent systems or products cannot rely on past experience – as long as one can see the monitoring images and can record them, the principle of whoever buys the lowest price should be guaranteed, and it must be ensured that the person can pre-prevent/alarm in case of abnormalities. Therefore, products must be purchased according to the following principles:

According to the principle of ensuring the highest security of the country and the people's interests (life and property), the purchase of security products by security developers can not only focus on their own profits, but which one they can not buy at low prices. The starting point should be the highest security principle of the country and the people's interests (life and property). In other words, the purchased product does not come out by blowing it. If it is purchased, it can only be used in name only, but it must be a product that has passed the assessment of the third standard grade that has been evaluated by a real expert, that is, it must be able to truly identify people and things. The product can be pre-alarmed in time when abnormal, so that it can truly guarantee safety.

According to the principle of choosing the right product with high cost performance ratio, the second principle of choosing the right product for the security product supplier to purchase the intelligent security monitoring system or product is to purchase the right product according to the principle of high cost performance. The high price of the product must be high performance, that is, intelligent features. If the same smart function, the same price, a product is not applicable; a product can only be used in indoor conditions; a product can also be used outdoors. Obviously, the performance and price that can be used outdoor can be higher, so it should be used.

According to the principle of on-demand distribution of intelligent requirements for monitoring sites, when choosing the right product for security, the security engineering company can not adopt new technologies and intelligent functions as “dogmas” when selecting intelligent security monitoring systems or products. The principle of on-demand distribution of smart requirements to choose the right product. If used in an indoor condition, the monitoring site only needs an intelligent function, so it is not necessary to purchase two or more intelligent function products, or a product in the third standard level range, without spending money. Purchase the fourth and fifth standard range products. In this way, according to the actual needs of customers to purchase the corresponding products, you can save money, so that security engineering business has a certain profit margins, but also let the good steel is really used to endure.

According to the principle of practice is the principle of testing the truth to buy the right product to win the bid The fourth principle of the security engineering company to buy intelligent security monitoring system or product is to choose the right product according to the principle of practice is to test the truth of the standard. The ancients remarked that it is better to see one another than others. Although such products may be expertly assessed and appraised by experts, the products in your hands may be subject to moisture. Therefore, you must go through your actual assessment assessment practice to see if the product's intelligent functions really meet the requirements of the standard. Choose the right product for your satisfaction.
