Smart fence identifies suspicious people

US scientists have successfully invented a sensor system attached to the fence, which can identify suspects who are trying to cross this protective network.

Small, low-power devices and human brain simulations can help the security system become superior thanks to the ability to distinguish trees from wind-blown or a person simply leaning on a fence. with a sneaky suspicious looking for ways to get past this protection network.

Until now, video cameras have only been able to do so, especially in monitoring every single centimeter of a large area, such as an airport. In fact, it has been proven that we need a smart surveillance system, especially after the suicide bombing at Domodedovo Airport in Moscow on January 24, killing 35 people.

One problem arises here is that the analysis of videos can produce false evidence when a significant shift occurs in the background due to weather. Image lines can be covered by trees, vines covered with fences or obscured buildings. To solve this problem, researchers from the University of Southern California (USA) have developed smart devices, capable of processing signals based on how the brain works.

Each device contains seismic sensors, programmed to identify movement types , including footsteps. These devices can be placed on the ground or attached to a fence. They will send a radio alert to a command center under certain conditions, such as having a plot to climb over the fence.

Discovery page quoted Professor Alireza Dibazar of the Department of Biomedical Engineering, University of Southern California - head of the project, said: " We have been authorized by the Navy and the US Transportation Security Agency (TSA). developing these technologies for areas where cameras cannot be installed, and we are trying to make it function and function like the human brain . "

Other scientists are developing a sensor system based on optical vibration, but Professor Dibazar thinks it will require more energy to operate. Meanwhile, the devices invented by his research team are running on batteries and only in the state of maximum energy use when suspicious motion is detected.

The team successfully conducted a series of successful " smart fence " devices at high schools and small airports around Los Angeles and international airports in Florida. Representatives from many airports sought to contact the group to order the installation of these advanced sensors. Currently, inventors are looking for a company that can commercialize their technology.
