Hubei Surveillance Evaluation Recommendations290

## Background
In order to ensure the safety of people's lives and property, and to effectively prevent and combat crime, public security departments at all levels in Hubei Province have attached great importance to the construction of video surveillance systems. In recent years, a large number of surveillance cameras have been installed in public places, roads, residential areas, and key units, which has played a positive role in maintaining social order, cracking down on illegal crimes, and serving people's livelihood.
However, with the rapid development of science and technology, the video surveillance system is also facing new challenges. The number of surveillance cameras is increasing rapidly, and the data volume is also increasing rapidly, which has brought great challenges to data storage, transmission, and analysis. In addition, the traditional video surveillance system is mostly based on analog technology, which has many shortcomings such as poor image quality, poor night vision effect, and low intelligence level.
In order to meet the new requirements of public security work, Hubei Province has vigorously promoted the construction of a new generation of video surveillance systems in recent years. The new generation of video surveillance system adopts digital technology, which has the advantages of high image quality, good night vision effect, and high intelligence level. In addition, the new generation of video surveillance system is also equipped with intelligent analysis functions such as face recognition, vehicle recognition, and behavior analysis, which can effectively improve the efficiency of public security work.
## Evaluation Criteria
In order to comprehensively evaluate the performance of video surveillance equipment, Hubei Province has formulated a set of evaluation criteria. The evaluation criteria include the following aspects:
* Image quality: The image quality of the video surveillance equipment is an important indicator to measure the performance of the equipment. The image quality is mainly evaluated from the following aspects: resolution, color reproduction, brightness, and contrast.
* Night vision effect: The night vision effect of the video surveillance equipment is an important indicator to measure the performance of the equipment in low-light conditions. The night vision effect is mainly evaluated from the following aspects: minimum illumination, signal-to-noise ratio, and dynamic range.
* Intelligence level: The intelligence level of the video surveillance equipment is an important indicator to measure the performance of the equipment in intelligent analysis. The intelligence level is mainly evaluated from the following aspects: face recognition accuracy, vehicle recognition accuracy, and behavior analysis accuracy.
* Stability and reliability: The stability and reliability of the video surveillance equipment is an important indicator to measure the performance of the equipment in long-term operation. The stability and reliability are mainly evaluated from the following aspects: mean time between failures, mean time to repair, and power consumption.
* Cost performance: The cost performance of the video surveillance equipment is an important indicator to measure the performance of the equipment in terms of cost. The cost performance is mainly evaluated from the following aspects: price, maintenance cost, and service life.
## Evaluation Results
Based on the evaluation criteria, Hubei Province has conducted a comprehensive evaluation of the video surveillance equipment of various manufacturers. The evaluation results show that the video surveillance equipment of the following manufacturers has excellent performance in terms of image quality, night vision effect, intelligence level, stability and reliability, and cost performance:
* Hikvision
* Dahua
* Uniview
* Tiandy
* Hanwha Techwin
## Recommendations
Based on the evaluation results, Hubei Province recommends that public security departments at all levels give priority to the use of video surveillance equipment from the above manufacturers when purchasing video surveillance equipment. In addition, Hubei Province also recommends that public security departments at all levels pay attention to the following issues when using video surveillance equipment:
* The video surveillance equipment should be installed in a reasonable location to ensure that it can effectively monitor the target area.
* The video surveillance equipment should be regularly maintained and calibrated to ensure that it is in good working condition.
* The video surveillance data should be properly stored and managed to ensure that it can be effectively used when needed.
## Conclusion
The construction of a video surveillance system is an important part of public security work. Hubei Province has attached great importance to the construction of a video surveillance system in recent years, and has achieved remarkable results. The video surveillance system has played a positive role in maintaining social order, cracking down on illegal crimes, and serving people's livelihood. Hubei Province will continue to promote the construction of a new generation of video surveillance systems in the future, and strive to build a safe and stable social environment for the people of Hubei.
