Problems solved by technology

The system also has problems such as camera shake during the recording process, low illumination at night, rainy and foggy weather, etc., which cause the video picture to be blurred, making it difficult to see the target, and the video formats of the video devices produced by different manufacturers are different, so it is difficult to be used in public security services. Defects in implementing unified management and utilization on the platform
