Andrzej Duda unveiled the barrier at its control centre in the northeastern town of Kętrzyn on Friday, Polish state news agency PAP reported.
Interior Minister Mariusz Kamiński accompanied the president during the ceremony.
Duda said: ”I am happy that the electronic barrier has been launched as it definitely represents an important additional part of Poland’s security system.”
The president added that for the past two years, Poland had been "under a hybrid attack" at its border with Belarus, with Minsk’s officials “pushing migrants towards our border.”
He said these actions “are undoubtedly coordinated with Russian authorities.”
Duda told reporters that the new electronic barrier, comprising “around 3,000 cameras” as well as motion sensors, would “protect our border against a potential influx of illegal migration” and against smuggling from Russia, the PAP news agency reported.
“And so it will help keep Poland secure and protect the interests of Poland and us all,” the president said.
