High-definition cameras with signal jammers in ordinary classrooms cause controversy

China Jiangsu Net, October 11th. Signal jammers, high-definition cameras, synchronized timing radio clocks... these electronic devices that should have appeared in American blockbusters or some high-end organizations in the eyes of ordinary citizens have quietly entered a certain Huai'an recently. Ordinary classrooms in colleges and universities. Controversy also followed. Some students reported that the mobile phone signal was poor, and others felt that they were being monitored at any time. To find out, the reporter visited the school yesterday morning.

Surveillance or surveillance? Students have different opinions

Student Xu, a sophomore at the school, told reporters that these electronic devices were probably installed a few days before the National Day. “But I didn’t care about it at the time. It was not until I came back from the National Day that I discovered that these electronic devices were installed in every classroom in the entire teaching building. "Electronic equipment." Student Xu said: "Everyone knows the camera, but we are not very familiar with the signal jammer. I originally thought that this white integrated circuit box was a wireless network signal amplifier or used to place a power switch. I didn't pay much attention to it."

Until the penultimate day before the National Day holiday, student Xu suddenly found that the signal in the classroom was particularly poor. "I sent a WeChat message more than a dozen times and it showed that the transmission failed. At first, I thought it was the cause of my mobile phone, but then he and I Several students who were in class together also said that the information could not be sent. Although the signal of the previous teaching building was also poor, it was not so bad. So everyone estimated that the white integrated circuit box might be a signal jammer."

The students of the school have different guesses about the use of these electronic devices that sound taller and look taller. Student Xu believes that these electronic devices should be used to urge students to concentrate on listening to lectures in class, "I think it’s good. Nowadays, very few college students can concentrate on listening to lectures without playing with their mobile phones. Sometimes teachers are embarrassed to take care of them. The effect is not very good. Now that the mobile phone signal is blocked, students can't play with the mobile phone. Although it can't solve the problem fundamentally, it can play a certain urging role in any way."

However, Ji, who was standing next to Xu, told reporters that these electronic devices are probably only turned on during the exam. They are used to prevent students from violating the discipline of the examination room. They should not be turned on every day. "If like Xu said, the school will use these electronic devices. It’s not so much urging as it is surveillance. And let’s not say whether the installation of the camera infringes the privacy of our students, just say that you block our mobile phone signals all day, in case you encounter someone at home or a friend. What can I do if I am looking for myself in a hurry, but I can't get through when I call myself?"

School: Usually not used, the shielding test causes the phone to lose signal

So, what are these electronic devices used for? The reporter found Xu Hong, the deputy director of the modern education technology center of the school. After learning about the students’ speculations and opinions on the use of these electronic devices, Xu Hong told reporters apologetically: “It may be because of the rush of time. Our school has not had time to explain to students the purpose of these electronic devices in detail. These electronic devices are used for The standardized examination room is not used in normal times, and it is not used to monitor students."

It turned out that the school has recently been striving to become the national graduate entrance examination test center from the Provincial Examination Institute and the Municipal Examination Institute. "If the application is successful, we will be the first among many universities in Huai'an." Xu Hong told reporters, "According to the national education According to relevant regulations of the Ministry of Education, if you want to become a test center for the graduate entrance examination, you must build a standardized test room, and the hardware facilities for building a standardized test room include signal shields and high-definition cameras." In addition, it also includes synchronized timing radio clocks, metal detectors, and ID card recognition device, "These electronic devices are also being equipped, and the construction will be completed in late November."

Xu Hong told reporters that these electronic devices are not normally turned on. “They will only be turned on when taking English 4 and 6 exams, adult college entrance examinations and other state-regulated exams. They are used to record student performance in the exam room and prevent violations of exam room discipline. The behavior happened.” As for the students’ report that the signal in the classroom was particularly poor two days before the National Day, Xu Hong was a little bit dumbfounded. “This is a misunderstanding. We debugged the signal jammer on September 27 and 28. At this time, there is no signal when using the mobile phone in the classroom. After the debugging, the problem of the lack of signal reported by the students will naturally not exist. In the future, we will need to debug and notify the students in time to try to avoid such misunderstandings from happening again. "
