Since 1995 Market.sk has been the leading innovator in the field of audio surveillance countermeasures. These solutions are regularly used to protect corporate intellectual property, mission critical conversations and national security. Did you know? Conversations can be captured from office or boardroom windows. Even with the best physical security policies, conversations taking place near unprotected windows are not secure from intentional eavesdroppers with professional equipment.

Eavesdropping protection systems are designed to prevent deliberate and intentional attempts to intercept private and confidential conversations. Since 1995 Market.sk has been the leading innovator in the field of audio surveillance countermeasures.

Laser listening devices can be used, at considerable distance, to capture conversation from minute vibrations on window surfaces. Secure Rooms When viewed as a six sided enclosure, the breech points of most rooms can be easily identified. Windows are vulnerable to laser listening devices, ductwork can easily channel sound to adjacent areas and doors form an obvious weak point. Sound transmission through utility penetrations, access floor cavities and above suspended ceilings can create a lack of confidential privacy. Doors Door maskers provide protection from intentional eavesdroppers by applying low-level sound masking to the door, filling the gaps around the door with protective sound. Windows Dynasound window maskers provide protection from laser microphones or sensitive parabolic listening devices which can be aimed at windows from a great distance.

Ram force of 24 tons is applied by a 5' diameter double acting hydraulic cylinder at 2500 psi pressure. The movement of the ram die is controlled by a 4 way, 3 position hydraulic valve. The length of the ram stroke is 8'.

HVAC Ducts Ductwork can easily channel conversations from one room to another, or can be used to hide listening devices. Duct maskers fill the interior of the duct with protective sound masking. Walls Wall maskers protect wall surfaces from spike microphones or other listening devices. Often in commercial office space there is no way to control who may have access to outer perimeter walls. Access Floors Reverberant spaces under raised access floors can channel sound from one office to another. Dynasound's DS1390 is designed for under-floor use. Off-site When a secure room is not available, confidential speech privacy is still attainable with Dynasound's PEP pack.

The DS2600 Portable Eavesdropping Protection system comes complete and ready to travel. Information protection, protection against eavesdropping, security against eavesdropping, anti-eavesdropping protection against eavesdropping, all we can provide. Noise generator, noise sources and generators? White noise generator, noise generator?

Mos def movies. The airplane, a nutty idea. The telephone, the Internet. People who envisioned those were considered radical or extreme.'

Noise generator, a device that produces white noise. This noise is linked to the piezoelectric magneto-dynamic transducers. Currently, it can not filter out this noise means any noise generator makes it impossible to carry out remote sensing acoustic information.
