School fence function
2020-01-15

Now, more and more school walls are filled with things similar to high-voltage power grids, with warning signs hanging on them. Four to six parallel "wires" are pulled on the school's 3-meter-high wall, and they are fixed with a middle pole every few meters. There are also yellow warning signs hanging on the "wire", which is actually an anti-theft electronic fence. So, is the school anti-theft electronic fence useful?

Why install an electronic fence? Schools are crowded at night, but there are also hidden safety hazards. Many schools have had night thefts. To protect the school's internal facilities and the safety of teachers and students, electronic fences have been installed on the walls, which can add a layer of protection against theft.

"Although the warning sign indicates high-voltage danger, it is not the same as the high-voltage power grid and does not cause much harm to the human body. In order to ensure the safety of students, it can also be taken during the day without power at night and turned on at night. The police will report immediately. In addition, schools should provide relevant safety education to students to enhance their safety protection capabilities.

Schools generally use pulsed electronic fences or tensioned electronic fences. The two “wires” with parallel pulses are actually alloy wires used to transmit pulse signals. Once someone touches or destroys the alloy wire, the pulse signal will be abnormal, and the pulse host will immediately alarm. Those who touch the net will have an instant electric shock, thus deterring intruders. The tension electronic fence mainly monitors the school perimeter situation in real time according to the change of induction force, and can promptly and effectively issue an alarm when someone intrudes.
