Description

Autonomous audio recorder OSA S4PL-T (for transport security) is used for autonomous, without operator's participation audio recording from microphones, intercoms and telephone lines. Recording is made without compression in PCM 16 Bit format on a removable micro-SD 10 class memory card up to 512 GB with subsequent archiving on an FTP server.Provides protection of audio data from interception and copying by encrypting records with AES key up to 56 Bit. Allows online audio broadcasting via RTSP stream on a media player, such as VLC.Audio recorder control is carried out via local network, to which it is connected via RJ45 network connector.Microphones, intercoms and line outputs from radios are connected to the terminal block.

Audio recorder provides power to 2 and 3-wire microphones, with a current consumption of no more than 15 mA.The ability to select one of the following recording modes: constant, by acoustic start, by schedule, from the control board PU-4.
