Waveform Archive
Additional to real-time waveform access the devices provision disk space for local waveform storage in MiniSeed format. Here day-files can be stored for physical retrieval from the field. This ensures that all recorded data is securely stored on a reliable storage medium on-site.
Depending on the sample rate the sensor and the equipped storage solution, the sensor can hold up to four years of 100 Hz data.
| 100 Hz | 200 Hz | 400 Hz | |
|---|---|---|---|
| 8 GB | 1 year | 6 months | 3 months |
| 16 GB | 2 years | 1 year | 6 months |
| 32 GB | 4 years | 2 years | 1 year |
High entropy noise will decrease the STEIM compression efficiency and result in a larger archive's size.
Archive Configuration
The waveform recorder can be configured at Waveform streaming > Waveform recorder.
Local Access and Download
To download data locally, e.g. from an offline sensor system, connect to the sensor over the local network.
MiniSeed data can be downloaded from the sensor using scp or other SSH file transfer clients:
rsync -avz qssensor.local:/data/mseed_data .The MiniSeed data will be organized in day files on the sensor.
