Wuxi remote monitoring - Security monitoring Three hot technologies in the field:
1、 Low illumination technology
Low illumination refers to ordinary video camera In the absence of infrared lights and other auxiliary accessories, the effect index of imaging in places with extremely weak light depends on its own lens, in Lux. Generally speaking, most surveillance cameras currently use active infrared for night vision. At present, a new technology has emerged, which can greatly improve the ability of low illumination of surveillance cameras. On the basis of no infrared, the ordinary surveillance camera can perform night vision through its own lens, and the imaging is clear and stable.
2、 Intelligent technology
Intelligent technology is the software that realizes its own value through video monitoring equipment. Through the current intelligent technology, video monitoring is more convenient and accurate. At present, intelligent technology is mainly divided into intelligent identification and intelligent analysis. Intelligent recognition technology is mainly used for face recognition to identify and compare strangers, suspects, etc. to confirm the identity of people. Intelligent analysis is mainly used to analyze the flow of people, road conditions, analysis and monitoring of the scene, etc.
Compared with the traditional video monitoring, the video monitoring with intelligent technology can analyze the accident in the first time and give an alarm in time. The suspects hiding in the crowd can be identified and tracked through face recognition. At the same time, intelligent analysis can carry out irregular high-quality analysis of a region, calculate the flow of people in each period, repeated people, and video clips that can be compressed and shortened to highlight key points. These functions can greatly improve the quality of video monitoring, reduce fatigue and improve the efficiency of monitoring.
At present, intelligent identification is mainly used for criminal investigation, monitoring of large secret places, access control identification, and even financial business of banks. The application prospect is very broad. And intelligent analysis is mainly used in areas requiring large-scale video defense, such as road monitoring, monitoring of crowded places, and special security.
3、 Iris technology
Iris technology has a long history, and it has been taking the high-end line in the application of access control, but rarely involved in the ranks of low-end products. Everyone has one thing that is different from everyone by nature, that is, the iris in the eye. It is a stable and reliable technology to confirm a person's identity by recognizing iris spots in the eyes. But before, it was difficult to popularize because of technical difficulties and price problems.
Compared with other access control technologies, the earlier iris technology has two major weaknesses: inconvenient recognition and slow recognition speed. Due to technical difficulties, when traditional iris recognition is used for recognition, the detected person must keep his eyes close to the machine before the machine can automatically read. And the speed of iris recognition is relatively slow compared with other recognition technologies, which brings a lot of trouble to recognition. Although its recognition accuracy is high, it is difficult to be accepted by the public.
However, the development of technology has brought it opportunities for development. At present, the speed of iris recognition has improved a lot on the original basis, and the recognition distance has also changed from the original close range to the current standing recognition, which is a breakthrough. Now, as long as the detected person stands beside the machine, the machine can automatically recognize the iris in the person's eyes for scanning, which is fast and easy to operate. At present, many manufacturers have begun to turn to the research and development of this product.
The reason why iris recognition is so attractive is that its accuracy is very high. We know that the error of fingerprint identification is relatively small, but it can still be broken through its access control through fingerprint sheath. The error of face recognition is even greater. If it is used for access control, it can only be used for the most basic community access control. It is inappropriate to use it in large security places. At present, iris recognition has the highest accuracy rate. In terms of practical application, if modern iris technology has a great improvement in recognition distance and speed, it is likely to take the lead in the field of access control.
