iProtect 3 Channel White Noise Generator Kit

Listening devices, bugs, thin walls or the carrying of a voice don’t stand chance against DNG2300-4 White noise generator sound masking system.

When is paired with transducers and speakers, it produces low level audible interference by creating vibrations onto surface in protected space. If any form eavesdropping devices are used will block voices instead pick up relay back vibrational created counter surveillance device. You’ll want to have good spread speakers amongst wallspace, number depend on size construction room. ( all device also sold separately) installation required.

It well-known that distributes through walls, doors, windows other constructions. some materials travels even better than air. For example, water conductor heating system can pass conversation out Eavesdroppers take advantage this use contact microphones. These microphones from air ducts, plumbing, structures, windows, floors, ceilings more. may not be same room as conversation, but several floors rooms away attached pipe fixture. DNG-2300 render useless. non-filterable acoustic which transferred constructions speakers. REI’s TRN-2000 recommended transducer DNG-2300. has optimal power parameters set different types surfaces. injects most its into surfaces while only tiny part gets inside does force people speak louder. supplied adapters mounting ceilings, etc. speaker OMS-2000 inject radiates surrounding usually ceiling tiles, etc

TRULY RANDOM NOISE

The consists 3 independent digital generators. “White” means fully equally distributed along spectrum. distribution provides complete resistance filtering conversation. Another feature unpredictability i.e. there no method wipe recorded

VOICE MASKING

Men’s women’s consist lots frequencies simultaneously produced during speech. lie between 100 Hz 6000 Hz. Listening narrower range mostly because limitations, scheme battery time. DNG2300 250-5000 cover suppress devices. class="spec-size-14">OPERATION

Features:

3 Channel x1 helps protect from

• Laser & Microwave systems using reflections windows
• Electronic stethoscopes (contact microphones)
• Microphones built construction
• Other Vibro-Acoustic methods information leakage

White generators widely protecting premises leakage SP2300 omnidirectional important component system. generated structures stopping distributing them, role fill voids, cavities ventilation shafts audio prevent

Creating voids/cavities increases general protection preventing kinds as:

• Listening help wall behind adjacent cavity (typically top floor drop ceiling)
• Leakage outside void/cavities (for common holes pipes system)
• Bringing wired void
• Hiding covert void cavity

Ventilation voids leading room

Ventilation makes possible carry without penetrating zone. propagates shafts/voids picked remotely. case sufficient distance run within shaft. order speech positioned void/shaft. large enough accommodate speaker, disassembled holders.

Since assembled them separately smaller voids. Disassemble removing triangle holders, cut cables, place where then connect again series.

• Use 1 x big shaft "1/3" void

Space

Sound directions; therefore, easily under ceiling. popular are:

1) Drilling hole tube extender preferred over direct hides signs work.

2) Placement bugging space

The mentioned methods. partitions ceiling, quantity selected correspondence following suggestions:

• 1 per 9-10 square meters

Connection

Depending choose wiring diagram below picture. Consider generator's minimum load (8 Ohm DNG2300)

The output divided so when more unit receive less power. percentage shows relative comparing variant parallel connection

• "100% level" shafts
• "50% – regular voids/cavities
• "33% small voids/cavities

Combining levels done, care should taken verify correct volume speaker. reflects power, real control. Typically, higher. determine conduct tests probe. test active adjust external probing capture near void/cavity.
