Modular architecture of the recording device

The recording device features a modular architecture. Records of calls are created by recording modules, using different technical means for example data cards or program modules. There are available modules for archiving of calls, for external diagnostics and user interface. The individual modules can be combined if necessary. Recording modules doesn’t need to be located in one server, but they can be located on several different servers interconnected by the computer network.

Servers have been standardly equipped with two hard disks in RAID disk array; to avoid the data loss in case of hard disk damaging, they are equipped with the redundant power supply source. data records about them can be further archived on data storage, located in computer network, eventually on local external drives.  The external diagnostic module enables supervising of the recording device state by means of the SNMP interface or the „Information panel“ application, which enables to supervise the state of the device and of individual lines and also of the “TOP” dispatcher workplace, by means of the state indicator.. 

Client and administrative user interfaces use Web services

The client and administrative interfaces are implemented through transparent web services.Users may not install any specialized applications on their devices through which they access the recording device. The application offers you the ability to search and sort your recorded calls according to a number of criteria. Users can access records based on assigned permissions. The recording device stores information on access, playback, and downloading of records.  For the sake of clarity, the recording device management application is implemented for clarity in a separate web application.

IP remotely controlled public address system

The public address system has been designed as a replacement of the existing RU-6 public address systems and of other similar equipment during the transition to the remote control system. It includes a high-power low frequency amplifier 300 W 100 V, control circuits for supervision, VoIP circuits for the input of low frequency signal in the digital form. Besides the standard features of the LF amplifier it includes functions needed for remote operation and supervision of the operating conditions.

Controlling public address system

The basic input of the low frequency signal is an Ethernet interface with VoIP Protocol and the option of the simultaneous operation of two independent channels. The first channel is designed for connecting to the centralized announcement system, the second channel for local or remote access using VoIP phone. The other connecting options of the lowfrequency signal are the line input and the microphone input.

The parameter settings

All settings of analogue parameters (volume, heights, basses, levels of individual inputs and their priorities) are carried-out digitally. Detection of the current state, control and configuration are possible by website browser. Current operating states and information from the inner auto-diagnostics can be transmitted into the superior supervisory system by SNMP Protocol and it is possible to record the operation history by SYSLOG Protocol. The internal real time clock can be synchronized using the NTP protocol.

The main advantages of IP  public address system

  • Fully remote- controlled and supervised public address system with power output of up to 300 W for 100 V distribution for the version with 230 V AC power supply and 150 W for the version with 48 V DC power supply.
  • Integrated input VoIP for direct connection to the digital infrastructure
  • 6 output loops with separate indications of currently broadcasted messages
  • Communication and control by standard protocols (HTML, SNMP, NTP, SYSLOG)
  • Option of direct coupling with the automatic announcement system

Regular operation

The regular operation is expected to proceed in the automatic announcement system, where compared with the existing equipment the use of an external computer with the sound card is not necessary.

Local or remote announcements via the standard VoIP network

Other options are the local or remote announcements via the standard VoIP network with a variable priority. For these two options the public address system uses two independent VoIP inputs.

Analog inputs

It is also possible to connect the input signal to the line or to the microphone input. Inputs use adjustable priorities.

Automatic switching of the day and night mode

Real time circuit is synchronised by NTP Protocol from the network and it allows as well automatic switching of the day and night mode.

Check of the carried-out announcements

To check the carried-out announcements current flowing through the line is measured in each of the six output lines. Input circuits formed by an output transformer, relay switching the output lines and output current sensor are galvanically separated by 4kV insulation barrier.
