In Technical Security Countermeasures (TSCM), confidentiality protection equipment plays a crucial role in ensuring the security of communications in sensitive spaces. These devices disrupt illegal eavesdropping and information theft activities in various ways. Audio jammers, utilizing ultrasonic technology, emit sound waves at specific frequencies to interfere with and prevent recording devices from capturing sound, effectively protecting private conversations from unauthorized recording. Anti-laser eavesdropping films installed on windows block laser devices from capturing indoor conversations, while call encryptors secure all transmitted sounds during phone calls, ensuring the privacy and security of telephonic communications. Electromagnetic shielding curtains block external microwave signals to prevent intrusion via microwave surveillance technology. Simultaneously, mobile phone signal blocking bags prevent the reception and transmission of cell phone signals, avoiding their use as eavesdropping devices. Together, these devices form a comprehensive confidentiality protection system, providing a solid line of information security for government agencies, corporate boardrooms, and other highly confidential environments.

Confidentiality protection devices are widely used in locations that require high-level secrecy, such as government offices, military installations, corporate boardrooms, courtrooms, and research centers. These devices are particularly suitable for environments that organize important meetings, handle sensitive information, or conduct highly confidential research activities, ensuring that all communications and discussions are secure from external eavesdropping and interference.

TSCM Confidential protection equipment can be used independently or in conjunction with wireless signal detectors, telephone inspection devices, and non-linear junction detectors to conduct comprehensive Technical Surveillance Countermeasures (TSCM) investigations.
