Every onboard channel recorded into one tamper-evident log on a single timebase, ready for any safety review or inquiry.
Each entry is hash-chained to the one before it, so the log cannot be altered after the fact without the break showing.
What the vessel recorded is what a later review reads, down to the second, on the bridge and ashore alike.
How the record is sealedPosition, machinery and video stay aligned on one timeline, so an event replays second by second, checked against what the cameras actually saw.
The same record serves the crew day to day and an investigator long after the fact.
An edge buffer holds the log through power loss and link loss, then closes the gap once service returns, so the window is never left empty.
NMEA 0183/2000, Modbus, analog sensors and IP video share a single timebase, so the order of events is never in doubt.
Hash-chaining makes any later edit visible, so the log can stand in a class, flag or insurer review rather than only an operational note.
Up to 24 channels record continuously from the moment the unit is installed, with no daily routine to remember and no gaps left to chance.
A single tamper-evident recorder that captures and time-synchronises every channel on board, and keeps recording through power loss.
