The Kamerton-3 system is designed to prevent information leakage via acoustic channels (through ventilation systems), and to prevent information leakage via vibroacoustic channels (through window openings, heating systems, doorways, walls, and other building structures). The system complies with the information security requirements for technical equipment installed in designated areas up to and including category 1.
The operating principle of the Kamerton-3 SVAZ is to generate a masking acoustic noise field and vibration around a designated area in which acoustic speech information circulates.
Advantages of the system The improved design and special manufacturing technology of vibration emitters allows minimizing the level of parasitic noise at protected facilities while ensuring compliance with speech information protection standards in accordance with their protection category; The use of a modern element base has made it possible to achieve significantly smaller weight and size parameters compared to existing analogues; Convenience and ease of installation of vibration emitters using patented fasteners; Possibility of mounting the generator on the wall; The presence of an LCD display allows visual monitoring of the generator's serviceability and ensures convenience and accuracy of adjustments for each of the noise channels; The use of new technologies has made it possible to significantly increase the number of connected vibration emitters; Possibility of creating protection for large rooms (up to 4 SVAZ "Kamerton-3") with control from "one button" using the universal remote control device "Molniya".
System composition Masking noise generator "Kamerton-3"; "Light" piezoceramic vibration emitters VP-3 and VP-4, designed to protect window panes and lightweight partitions; "Heavy" electrodynamic vibration emitters VD-80 (medium power) and VD-120 (high power), designed for noise reduction of heating pipes, walls and ceilings; Acoustic emitters AS-Sh (for open mounting) and ASP (built-in) for noise reduction of air ducts, vestibules and doorways; Mounting equipment: a set of fasteners for a frame, a pipe, plasterboard, a wall, a mounting box.
Series-parallel connection of VD-80 (VD-120) and AS-Sh (ASP) is allowed, provided that the total resistance of such a circuit for direct current is not less than 2 Ohms.
Parallel connection of N emitters
Total resistance is N times less than the resistance of one emitter
Rн=R/N
Radiation level - maximum
Series-parallel connection of emitters - 4 groups in parallel, 2 emitters in series per group
Total resistance Rн=R*2
Radiation level is less than maximum by 6 dB.
Series-parallel connection of emitters - N groups in parallel, M emitters in series per group
Total resistance Rн=R*M/N
Radiation level is less than maximum by D=20 lgM:
M=2, D=6 dB;
M=3, D=9 dB;
M=4, D=12 dB;
M=5, D=14 dB
