How to make security video valuable? Look at what the big buddies in the industry say.

How to make security video valuable? For such topics, security industry giant Dahua has a very strong voice. Zheng Hao, director of research and development at the Dahua Advanced Technology Research Institute, first pointed out: "Unlike movies, TV and other large information videos, security video has less effective information. And the process of human viewing is boring."

It is true that with the improvement of people's awareness of security and the large-scale construction of safe cities, surveillance cameras have been densely spread throughout the city, and the amount of data has been greatly increased. Whether it is real-time video or post-recording, the only way to get valuable information from users is to “see”; but in the video information 24 hours a day, it may only be a few minutes to be effective. Making rapid and effective judgments in massive data consumes energy and wastes material and financial resources.
 


Zheng Hao said: "For the entire security industry, the stage of extensive use and installation of cameras has been completed. At present, the most important task of the security industry is to solve the contradiction between massive video and increase the value of video, and use artificial intelligence, deep learning. The algorithm can alleviate and resolve this contradiction, allowing customers to enjoy the benefits of video value and its added value."
 
Artificial intelligence leads digital transformation and management
 
86% of CEOs believe that in the next five years, digital technology will be the primary driving force for enterprise transformation. The use of intelligent platforms to improve internal management and service efficiency has become the choice of more and more enterprises. Lin Shuangshuang, a senior pre-sales engineer at Sanwu Internet, said: "Traditional office platforms face difficulties in terms of channels, services, costs, efficiency, and experience. Thanks to the impact of the mobile Internet, the company's office management methods will no longer be limited."

It is reported that in the next few years, China Mobile's SaaS service business market will continue to grow. The three-five interconnections rely on independent research and development of application software systems to provide OA services to the industry in the form of SaaS, including traditional, mobile, social and Four major trends in corporate information services. At the event site, Lin Shuangshuang introduced the attendance management solutions, classic application cases, etc., which were included in face recognition, fingerprint recognition and password recognition, and analyzed the new office mode in the intelligent era.
 
Front-end vision will break through the limitations of visual technology scenes
 
One of the characteristics of artificial intelligence is the ability to perform "human-computer interaction". In this piece, the most representative ones are speech recognition and visual recognition, and they have been applied in the security field. However, unlike voice recognition, visual technology is still limited in many scenarios. Enterprises need to upload the collected data to the cloud or server for calculation. In addition, taking into account the influence of uncertain factors such as delay, the information is instantaneous. Sex will be greatly reduced.
 

Reader Technology CEO Zhao Jinglei
 
As an artificial intelligence company that focuses on deep learning and embedded solutions and is committed to solving visual recognition problems, the face-to-face technology has made remarkable achievements in the above problems. CEO Zhao Jinglei pointed out: "Under the influence of deep learning, computer vision has undergone three major changes. One is to change from static image processing (such as a pair of people in the financial field) to dynamic image processing (such as robotic automatic driving). The second is to change from passive vision to active vision (such as service robots), and the third is to start from the back end to the front end."


The above picture shows the three architectures of the computer vision system: it can be seen that the algorithm is gradually embedded in the front end of the device to run, which can reduce the dependence on the cloud and additional servers.
 
Speech recognition becomes the most natural way of human-computer interaction
 
As mentioned above, speech recognition is one of the most important ways of human-computer interaction. As security enters the era of intelligence, the security department has introduced this technology more to combat criminal activities, and speech recognition has gained more. Growth opportunities. In the voice recognition section, HKUST is a leader in the industry. At present, the recognition rate of the University of Science and Technology has reached 95%.

At the event site, Tu Kanghong, product manager of the intelligent hardware business department of Science and Technology, introduced the related contents of speech recognition, semantic understanding and speech synthesis, and mentioned in the realization of more natural human-computer interaction and the improvement of far-field speech recognition rate. A microphone array that makes the ears of the machine more sensitive.
 
"Two microphone arrays are suitable for front, middle and short range voice interactions in normal environments. They are generally used in wearable devices. The four microphone arrays are suitable for front and long distance voice interaction in noisy environments, and are applied to large household appliances such as air conditioners, and six microphones. The array is suitable for omnidirectional, long-distance voice interaction in noisy environments, mostly in the field of robotics."
 


A microphone array is a system of a number of acoustic sensors (typically microphones) that are used to sample and process the spatial characteristics of the sound field.
 
Service robots make families safer
 
Security + AI is a broad and valuable topic, said Hu Zhonghong, CEO of Husky Robot: "Talk about the topic of smart security + AI application, and put it into the overall consideration of the system application scenario." He mentioned family security, community Safety, building safety and urban safety, and corresponding to smart homes, smart communities, smart buildings and smart cities, on the spot one by one.
 

Husky Robot CEO Xiang Zhonghong
 
"At present, computer vision is the technology prospect of security + AI, so equipment AI will become a key trend in the industry, which will help enhance the device's perception, interaction, and bring more cloud computing capabilities." Zhonghong seems that with the emphasis on medical health, the application of artificial intelligence in health care is regarded as a promising direction, and the service robot used in the security field is such a landing product.

Stainless Steel Kitchen Faucets

Stainless steel Kitchen Faucet is a faucet made of stainless steel. Stainless steel is a healthy material, without lead, acid, alkali, corrosion resistance, does not release harmful substances, can ensure human health and hygiene. Stainless steel kitchen faucets are safe and lead-free, with no corrosion and exudates, and no odor or cloudiness issues. It will not cause secondary pollution to the water quality, keep the water quality pure and hygienic, and fully guarantee the health and safety. Field corrosion test data show that stainless steel has a service life of up to 100 years and requires almost no maintenance during the life cycle, avoiding the cost and trouble of faucet replacement and low operating costs. Achieve the same lifespan of a stainless steel kitchen faucet as a building.
