One of the long range spying systems was placed on Sannine mountain, which overlooks Beirut and the eastern Bekaa Valley, and the second was on Barouk mountain, southeast of the capital, the army said in a statement.
The system found in Sannine included a camera, a device to send images and a third to receive signals, the army said.
The device found in Barouk was “much more complicated.” The army said it plans to remove the cameras and urged citizens to inform authorities about any suspicious objects they find. The military was tipped off about the systems by the militant Hezbollah group, the statement said.
The Israeli military had no immediate comment.
Earlier this month, Hezbollah said it discovered an Israeli device spying on its private telecommunications network.
Lebanon and Israel are officially in a state of war. More than 100 people in Lebanon have been arrested since last year on suspicion of collaborating with Israel.
