CT Systems for Covert Communication
Inductive systems:
In its basic configuration, a complete inductive system for covert communication consists of an inductive receiver (ear piece), inductive coil, push to talk button (PTT), microphone, radio plug and the necessary connecting cables
All components are normally available in beige or black color
Different types of surveillance work may require different system configurations. Along with systems having permanently wired component connections, Ceotronics offers a unique pluggable system. Here, all system components can be customized, selected and combined shortly before the job starts. The plugs and sockets are designed to be unambiguous and are color coded to eliminate the possibility of incorrect connection
If an element of the system should fail, or is to be replaced by a more suitable component, it can be replaced without tools. This makes the pluggable versions extremely cost effective in the long run

CT-DigiCom, Digital Inductive Receivers

CT-DigiCom digital inductive receivers are fitted with a digital signal processor that is able to detect speech. All incoming signals are digitalized and analyzed and only speech is passed on. In spite of this, transmission of PTT signalizing is possible!
The new receiver is absolutely insensitive to electromagnetic interference. Low or high frequency interference, e.g. in vehicles, aircraft, on motor cycles, in railroad stations, on offices or department stores do not interfere with clear communications
An interference-free standby function, instead of squelch, keeps the system ready for operations. The first signal from the radio, the first syllable of an incoming message, or even weak radio signals, are never lost. This makes communication even more secure, especially in difficult situations.
Through AGC (Automatic Gain Control) listening with the digital receiver is even more comfortable. Low signals or defined frequencies are amplified in the factory preset settings and others are automatically limited. These stored basic volumes can be readjusted individually with a rotary volume controller.
The receiver is switched on and off through the battery compartment. The receiver can be operated for up to 40 hours; an acoustic warning is heard on "low battery".
The inductive receiver sits invisibly in the ear like a hearing aid and comes in 4 sizes. There is also a version with individual ear mold. The housing is made of anti-allergic material that adapts thermo-elastically to the ear channel. A nylon thread on the housing makes it easy to remove the receiver from the ear. The CT-DigiCom is maintenance-free; where necessary the cerumen filter is replaced (quick-change system). CT-DigiCom inductive receiver is shipped in a small flat box with 1 battery, 6 cerumen filters with quick-change tool and 2 cleaning tissues

Inductive Receivers
The inductive receiver sits invisibly in the ear canal like an hearing aid and is available in different sizes for nearly all ear canal diameters. There is also an individually moulded version. The housing consists of anti-allergenic material that adjusts thermo-elastically to the ear canal.
The CeoTronics receiver has an on/off switch (size: XS: on/off switching by battery compartment) and infinitely adjustable volume control for comfortable hearing, as well as improved electronics for excellent reception. The low power consumption means that a single battery provides nearly 170 hours of continuous use. The receiver housing is sturdy and the electronics are resistant to interfering radiation sources.
Because there are no squelch electronics, even weak signals can be received and PTT squelch signaling is possible. There is a nylon thread on the housing to facilitate the removal of the receiver from the ear.
The inductive receiver is equipped with an earwax filter. A cleaning tissue is all that is needed to clean the filter. No tools are required and there is no replacement earwax filter necessary

CT Ear Microphone/Speaker Systems

Ear microphone/speaker systems are used for covert and semi-covert communication, for tactical operations in combination with respirators and gas masks, etc.

The key part of the ear microphone is a transducer, which is used as a speaker and microphone. Together with an earpiece and/or an earhanger the microphone/speaker capsule is worn unobtrusively in or at the ear. From here, a thin cable leads to the PTT housing, which also contains the electronics. The radio connection cable coming from the PTT terminates with the required radio connector.

The radio can be worn concealed under the clothing. The electronics are adapted to the radio as indicated.

EarMike/Speaker Set CT 475
The CT 475 has a large surface, easy to operate PTT button with built-in electronics. The PTT button is worn on or under the clothing and can also be operated with the arm/elbow, so that the user always has both hands free. The clothing clip on the rear can be adjusted in steps of 90 degrees. The connection cable is pluggable at both ends for quick replacement. Optionally, an additional hand held PTT button is available. A metal earhanger with rubber plug and an audio tube are within the supply.

CT Communication Systems for Use with Helmets and Masks

The variety of applications, the different helmet and full face masks models and varying personal preferences are reflected in the numerous communication systems that CeoTronics provides.

Together with the standard versions shown here CeoTronics can also supply tailor made solutions and modifications on request. These include communication systems for bomb disposal helmets, or for installation in helmets for use with snow mobiles. Also compact units, consisting of a speaker and a ContactCom contact microphone, or speaker and boom microphone are available, which are fixed in the side straps for bicycle, horseriding, skating and mountain rescue helmets.

ContactCom/Speaker Communication Systems for Helmets and Full Face Masks
The original CeoTronics ContactCom is a contact microphone that picks up the voice from the top of the head (skull) and amplifies it for transmission by a radio.
Ideal for use with helmets and masks in application where conventional lip microphones, with or without a boom, cannot be used.
The special design with a flexible anti-aging bellows, which contains the acoustic pick-up, is warranted comfortable to wear with optimal contact to the top of the head, even after many years of use.
The amplifier board does not come into contact with the microphone capsule's, and therefore cannot be damaged. Clear audibility of the speech signal even in noise levels of 90-100 dB(A).
The microphone and the speaker are integrated in the helmet in a way that no parts protrude. This increased safety and avoids injuries. Because of the modular design, parts are easily replaceable.
Between the microphone/speaker combination and the PTT button there is a weather-resistant easy-to-handle safety connection.
The CT-ContactCom system is matched individually to the radio. When placing the order, please indicate the manufacturer and model.

BoomMike/Speaker Communication Systems for Helmets
CeoTronics BoomMike/speaker systems have an excellent transmission quality. The noise cancelling microphone is on a flexible, sturdy boom arm, which always remains in the set position. This way the microphone can be placed in the optimal position in front of the mouth. The microphone and speaker are attached to or in the helmet in different ways. This depends on the helmet model and type of application.
Between the microphone/speaker combination and the ptt button there is a weather-resistant easy-to-handle safety connection.
