→Alarm recordings
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 beginning of the recording window (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 end of the recording window (t<sub>A</sub>). This scheme is convenient for automatically processing the frames because it allows to order them very easily.
The second part of the file names is the relative time offset (expressed in seconds) with respect to the "alarm frame." The alarm frame, in turn, is the first frame captured after the detection of an alarm signal. Consequently, the alarm frame is always named as <code>n_+0.000000000.bmp</code>. In other words, this frame is associate associated with t<sub>0</sub>. In the example shown above, the alarm frame's name is <code>002424_+0.000000000.bmp</code>. This rule allows to determine straightforwardly how close a frame is to the alarm event. For instance, see the following image that refers to a screenshot captured on the processing platform itself.
