• •Advanced laser eavesdropping techniques can reconstruct conversations from outside a building.
• •Demand is rising for devices that detect laser beams and block electronic signals.

China's counter-surveillance industry is experiencing significant growth due to heightened fears of foreign espionage. The Ministry of State Security has warned about advanced laser-based eavesdropping techniques that can detect vibrations in glass windows to reconstruct conversations. This has led to increased demand for counter-surveillance equipment, including laser detection systems and electromagnetic-shielding curtains. The market is responding to Beijing's tightening national security requirements and the need for protection against foreign surveillance technologies. Reports indicate that specialized devices capable of detecting incoming laser beams and blocking electronic signals are in high demand. The situation reflects a broader trend of increasing security measures in response to perceived threats from foreign entities.
