High-tech police

Los Angeles Police Department (USA) offers a hypothetical situation: There is a suspect who has just escaped from the detention center. The plan to arrest the fugitive was immediately deployed. But instead of organizing dangerous high-speed chases in the streets, Los Angeles police can now capture objects without spending a lot of effort with the Global Positioning System (GPS). Controlled by laser, mounted in front of police car.

When clinging to an escapee's car, the police will fire the signaling device at the rear end of the object (Figure 1) . With the help of GPS, police can easily grasp the suspect's path through wireless networks. After that, they just need to locate the stop on the map to capture the culprit.

William Bratton, Los Angeles police chief, said the technology would help reduce the risk of danger to police in street criminal raids. Technology is being tested in Los Angeles and Suffolk district in New York. StarChase LLC is planning to launch it in early 2008.

The tactics of arresting criminals are different from place to place, but most policemen sitting in high-tech cars can shoot bullets (signals) into criminal vehicles through the dashboard on the speedometer (figure 2) . The Los Angeles Police Department's ' bullet ' shot has now been improved to a battery-powered device, allowing it to signal every 3 seconds. Trevor Fischbach, StarChase's vice president and inventor of the criminal vehicle tracking system, said that with this technology, police can track the vehicle they are looking for, determine the direction and speed. its degree. On the police car, there is also a map to determine the coordinates of the vehicle of the escapee.

In addition to the above-mentioned criminal vehicle tracking technology, the Los Angeles Police Department also partnered with Motorola Corporation to provide a video surveillance wireless network application in the Jordan Downs public housing project. Accordingly, images taken by 7 live cameras will help police track down suspects - even before the patrol forces arrive at the scene .

Meanwhile, police departments in many other US cities are also applying new technologies, such as unmanned aerial vehicles (UAVs) to catch criminals. The UAV is about the size of a model airplane, can replace helicopters, and it is difficult for criminals to recognize and help the police have an aerial view in emergency situations. Safa Egilmez, an expert in crime prevention technology in California, said some types of UAVs are suitable for installation in police cars and can take off within 15 minutes. They are easy to control and can transmit information and pictures of police cars as well as police headquarters over the wireless network.

Meanwhile, police in towns are using wireless Internet technology to share information about crime. Usually, criminals in large cities when chased will run to the town hiding. Therefore, sharing data online will help local police capture information to promptly support or coordinate with colleagues at higher levels.

In Santa Monica, west of Los Angeles, Egilmez uses computers and knowledge of geographic information networks to track crimes throughout the city. His criminal activity map can help patrol police find criminals, even when they are committing criminal acts.

In Hoboken (New Jersey state), the government uses computer technology to manage and monitor parking. A Motorola spokesman said that by attaching a radio frequency identification chip (RFID) to the rear end of a local person, parking managers just need to look at a laptop to distinguish people. local and remote visitors, thereby easily tracing the suspect object.
