A team of researchers in China have found a way to use glass door tracking to track down and defeat intruders.
According to the team of scientists from China’s Academy of Engineering Science and Technology (AEAST), the technology can track down any door in a building and even shut it down, so that it does not break open.
“Glass door tracking is a method of detecting intruders,” said Li Xiaoping, an assistant professor of electrical engineering at AEAST, who has worked with the team to develop a system that uses light and sound to detect intruders in a glass door.
“It is not a physical tracking device, but an intelligent system that monitors the position of the door,” Li said.
“It is also able to monitor the movements of the light emitted by the door.”
The team has developed a method for detecting a person’s footsteps from a moving glass door that is about 4 centimetres thick, with a height of 5 centimetre.
Using a laser, they then use sound to find the exact location of the sound, based on the distance from the door to the person.
The method can also be used to shut down an unoccupied door, as long as it is within the 5 centimeter range.
“The main problem with a glass-door tracking system is that it is very noisy and not as accurate as a physical door tracking system,” said Xiang Zengxiang, the senior scientist who developed the technology.
“Because it uses optical sensing, it is not able to track any type of intruders inside the glass doors.”
The researchers say they hope the system will be useful for monitoring intruders from other locations as well, such as from the roof or in the attic.
They hope that this technology will be able to help security agencies and other organisations better detect and detect intrusions.
“If you want to find people, you cannot just look for footprints inside walls, but you also need to detect the movements in the room,” Xiang said.
“This kind of detection can help you to find someone, especially if you want a good reward from the people who help you.”
