Outdoor Loudspeaker GVC-1 for Sound and Video Notification Systems

The loudspeaker is designed to notify the listener by means of audio and video information. The main feature of the loudspeaker is the reception of radio signal from the server station by means of radio modem (the identical radio modem is installed on the server radio station as on the street loudspeaker), which in its turn is both a receiver and a transmitter at the same time with the possibility of retransmission of radio signal in the permissible range of radio frequencies. The radio modem installed on the server station sends encrypted text information, in its turn the radio modem on the loudspeaker receives the signal, decrypts it and with the help of Special Software (hereinafter referred to as SW) plays back the voice message according to the scenarios recorded in the loudspeaker memory in advance. The voice message is also displayed on the LED modules in the form of a ticker in text format.
