In the past decade or so, China's security industry has sprung up. Surveillance probes have long become standard equipment in cities. The use of new technologies such as signal tracking and network monitoring has completely changed the way police handle cases.
China's public security has a history of fighting crime and has fully entered the era of electronic criminal investigation.
Hangzhou is the capital of China's security industry, and several of the country's largest security companies are located in it. This city is second to none in the country in terms of security hardware and police electronic criminal investigation level.
In 2021, Hangzhou hosted the G20 Summit, which gathered leaders from various countries. However, just half a year before the summit, several cases occurred, which caused difficulties for the security of the entire city.
A gang of home invasions and robberies has been committing crimes in high-end residential areas one after another, but has never been caught on surveillance cameras like a dragnet.
A car equipped with satellite positioning disappeared from the main city and finally appeared in the suburbs more than ten kilometers away. Monitoring along the road did not capture the whereabouts of the car, but satellite positioning showed that the car was running at a speed of 300 miles per hour all the way to the destination, the speed of a high-speed rail!
