Multichannel Digital Recorders for Security and Communication

Advanced Technology for Radio and Telecommunications Recording

When telephone and radio communications take on vital importance for your business or for emergency and security situations, then it becomes essential to be able to document them reliably and accurately.

The reconstruction of events based on telephone and radio conversations cannot be reliably clarified by written notes and statements of people who, in the event of a dispute, rarely coincide.

The recording of communications, with date/time association, becomes essential for clarification, verification, analysis and transcriptions.

Public Security and Emergency services

Control centers need TEMA TDR recorder technology to record and archive all emergency calls, radio communications and other telephone calls.

The data associated with the recorded communications (Date/Hour/Minute/Sec., Caller number, radio frequency, channel number, operator position) allow you to subsequently perform an intelligent search according to numerous criteria to find the required communications quickly and comfortable.

The "Instant Listening" function allows you to listen to the latest communications received in case of doubt or misunderstanding. The historical archive of recordings on modern and comfortable DVDROM, DVD-RAM and DVD-RW media represents a guarantee for checks and any future investigations.

Air and Sea Traffic Control

In accordance with the international directives on air and sea traffic control, all communications between air and land and between ships and port should be recorded and archived for no less than 30 days in order to be listened to in the event of any investigations.

TEMA TDR series recording systems are ideal for this type of application, and they also allow immediate playback of a communication in case of misunderstanding or signal disturbance.

Financial Transactions

Voice and data recording has become a must and, in some states such as Europe, a legal necessity for all banks, stock brokerage firms and insurance companies.

The ability to immediately listen to a communication from a broker or an order from a customer communicated verbally is essential to avoid misunderstandings that would lead to unpleasant consequences. The individual historical archive of recorded communications can produce irrefutable evidence in the event of disputes..

Tertiary and Services

Customer calls for service interruptions, radio communications with mobile service units and more are part of the daily business of service sector operators, such as supplies or connections for public or private entities.

The immediate replay of a communication can immediately clarify operational aspects, the historical archive of communications will prove to be an irreplaceable tool in the event of disputes or legal practices.

Call Center

Customer calls for teleshopping, technical assistance, support, tollfree numbers, complaints. The recording can take place "on demand", or activated by the operator, or continuously directly on the telephone line with the acquisition of information on the calling number and the number called.
