The rapid development of intelligent hardware has exceeded our imagination. Just as we struggled with how popular household smart bulbs became popular, smart hardware that helped police maintain social security was born. It is certainly not something we have heard on weekdays, but a smart streetlight that can detect gunshots.
Recently, according to foreign media reports, GE's smart city project will take a tougher stance in curbing gun violence. In the future, the gun sound detector developed by ShotSpotter will be placed in the street lights of its smart city. It is hoped that this streetlight system will help the legal institutions to obtain the precise position of the gunshots as quickly as possible.
There is no doubt that the widespread use of GE smart streetlights will be of great benefit to the public order, because “ShotShotter can accurately check the location of the shooting, the number of gunshots and the number of gunsâ€, and “once the streetlights check and locate the location of the gunshots It will send messages to the police, legal dispatch bases, and police officers' smartphones. As a result, the police will be able to handle cases quickly, thereby reducing urban insecurity.
However, this kind of intelligent street lamp may have certain binding force on the gunners and can greatly improve the efficiency of the police. However, for those who are at risk, the police will only receive relevant information when the gunshots are issued. It is already late. In this way, the "NFC Alarm System and Method" (hereinafter referred to as "NFC Alarm System") of IOT will be better in terms of security.
Not long ago, Lu, a 33-year-old dance teacher from the Music Department of Baoji University of Arts and Sciences, disappeared in the night. Six days later, the body was found in a remote place. Previously, there were girls in Ningbo, Hangzhou and other places who were in distress when they were running alone at night. For the occurrence of such tragedies, intelligent street lights capable of detecting gunshots are powerless, but the NFC system is entirely possible to avoid them.
As a global provider of IoT devices and solutions, IoT has long been committed to the development of IoT hardware and is a leader in smart homes . The NFC alarm system is one of the many IoT invention patents of IoT. It was submitted three years ago and was authorized in November last year. However, even today it is still a very innovative and practical invention.
Simply put, the NFC alarm system mainly consists of NFC tags and mobile phones (with NFC-enabled smart mobile terminals, such as smart phones, watches, etc.). The operation is very simple, that is, in the case of dangerous situations, the user only needs to Contacting NFC tags with your mobile phone, including geographic location, voice data, etc., will be silently sent to authorized user terminals or security centers.
For example, if a user suddenly encounters an illegal molecular hijacking outdoors, and has no time to call for help or an alarm, then the mobile phone needs to be close to an NFC tag (such as a bag or the like) provided at any position. The mobile phone receives the alarm command issued by the NFC tag through the NFC module, and sends the real-time geographical location information, voice data and alarm information to the authorized user terminal or the security center after the analysis and processing. In addition, if the criminals shut down the hijacked mobile phone, the system will also control the power system of the mobile phone to enter the "false shutdown state" without affecting the alarm result.
Of course, the NFC alarm system can be used not only in outdoor night running, commuting, travel, etc., the current main business of the company is smart home, so this invention can also be used for family life and daily office space. For example, if the family encounters external dangers and other dangerous situations, it is more convenient to use this alarm system than to call. Similarly, the NFC alarm system can also be used to build a smart community security system with cameras and other devices to ensure community security.
Finally, we may wish to open our minds. In many European and American movies, we will see some such bridges. In the case of bank or jewelry store robbery, the hostages want to report by phone. The result is basically the result of light injury, heavy sacrifice, and if there is What about an NFC alarm system? Will the alarm be more concealed and safer?
