The name of the subdirectory (<code>2020-08-06_10.30.08_CEST</code>) is self explanatory. File names formatting is a little bit trickier and looks like this:
<pre><progressive counter>_<time offset relative to alarm frame>.bmp</pre>The first part is a progressive counter, starting from 000000. In other words, the image whose file name is something like 000000_x.bmp refers to the frame captured at the time t<sub>B</sub>. At the other end, the image whose file name starts with the highest counter refers to the frame captured at the time t<sub>A</sub>.
The framessubdirectory used for this example cointains around 3300 BMP files, as the alarm time window is 11 seconds and the frame rate is 300fps:<pre class="board-terminal">sysadmin@hfrcpoc1-0:/mnt/alarms/2020-08-06_10.30.08_CEST$ ls *.bmp | wc -l3333</pre>
