Solar energy has taken on a new role in combating the theft of electrical cables, one of the crimes that causes the most damage to urban infrastructure.
In Rio de Janeiro, where this type of incident is recurrent and fuels the illegal metal trade, the State Department of Education has begun installing a solar-powered alarm system in more than 1.200 state schools, with the aim of preventing further break-ins and preserving the operation of the educational facilities.
The main feature of the equipment is its autonomy, as it operates independently of the electrical grid. The system remains active even when criminals cut the school's wiring during an attempted burglary, a situation that would normally render conventional alarms useless.
The initiative is part of a set of measures adopted by the department to reduce the damage caused by thefts and to avoid the suspension of school activities.
Alarm has already prevented another theft.
The first school to receive the equipment was the Ciep Brizolão 320 Ercília Antônia da Silva, in Duque de Caxias. Just a few days after installation, the system was put to the test.
According to the Department of Education, at least three criminals broke into the school in the early morning of July 10th and attempted to steal electrical cables that had been reinstalled just a few hours earlier. As soon as the wiring was cut, the solar-powered alarm activated automatically.
The device emitted a high-intensity beeping sound, enough to wake up neighbors. Surprised by the activation of the equipment, the intruders interrupted their actions and left the scene without completing the theft.
According to the department, choosing a solar-powered system eliminates the main vulnerability of conventional security equipment, which is its dependence on the electrical grid.
