Tracing the development history of security video surveillance, with the improvement of the level of science and technology, the security video surveillance industry has gone through the analog era, the digital era and the high-definition era. With the blessing of emerging technologies such as technology, the era of intelligent video surveillance is coming.

In the era of security intelligent video surveillance, the video surveillance industry has completed the city-wide video surveillance, dynamic face control, face capture and other related links, but only by embedding the "face recognition" algorithm, the security camera can be praised as having a Is a "smart" brain enough to support the intelligence of the video surveillance industry?

The answer must be no. In the era of intelligent video surveillance, "smart" security cameras, in addition to recognizing faces in video data, should also be able to quickly capture key information from massive video data and analyze them, such as people counting, abnormal crowd analysis, etc. Video connection structure function; at the same time, it also needs a pair of "eyes" with super night vision function, which can still conduct full-color video surveillance in low light or no light environment... That is to say, a truly "smart" security camera, Must have the ability to think actively.

Of course, the formation of "smart" security cameras is not as simple as imagined. The so-called "smart" here must involve cloud-side-end intelligence, including the integration and application of multiple intelligent technologies, and also including multiple chip technologies. and further development of algorithms.

At present, security companies are constantly pushing security cameras suitable for different scenarios to the industry. So, what is the effect of their security cameras? Can it match the actual requirements of the scene? And is it really smart? a&s will analyze them one by one in the actual product and solution testing.

In this evaluation, 12 products and solutions from 7 companies including Guangtuo, Hikvision (6 models), Huawei, Jiajia Smart, Yufan Smart, EZVIZ, and Zhinuo Technology participated in the evaluation. The performance details are presented to the readers through the measured data, and the intelligent function of the product is used as the test point, focusing on its realization effect.

With 20 years of accumulated rich media resources and professionalism and authority from the perspective of a third party, a&s adheres to the principles of objectivity, impartiality and fairness, and fully displays the performance, characteristics and application status of the tested products and solutions. The detection method is basically the same as that of the industry, and will not be introduced in detail here. In-depth analysis of the function and performance of the device from all aspects. One by one, the post-test sense records are made, and the comparison and analysis with previous similar products are carried out to obtain the progress of this product, and provide users and engineers with high-value, objective and comprehensive product information and technology development trend reports.
