The unit features a flash disk embedded operating system designed for straightforward installation, with a compact modular assembly that is user configurable via a terminal computer.
The Protected Data Unit (PDU) has a standard recording capacity of 2 GB which can be downloaded via an Ethernet link in 15 minutes. A special float-free protected data unit with an extended memory capacity of 8 GB is also available.
Data for the S-VDR is gathered from a pre-assembled 16-channel Main Unit (MU), which provides for 9 microphone and 3 VHF input interfaces, together with up to 4 video source inputs for radar and ECDIS (electronic chart display information system), or CCTV, and a port for AIS data.
SAM says that the recorded data can be retained for more than 10 years without power supply, and that a number of the new systems have already been commissioned by leading ship operators in Europe.
