Timeline display

Sound reproduction is synchronized to video playback to a certain extent. Absolute
synchronization is not possible because the sound card and the frame grabber
record separately from each other.
Extreme system operating conditions can also result in serious image-sound
displacement or not all frames being shown (dropped frames) during playback.
The timeline display is a graphic display of the recorded images per camera over a
time axis.
One line (track) is displayed for each camera. A maximum of one overview track
plus 8 further tracks can be viewed simultaneously. The overview track shows all
stored recordings of each camera within the timeline. The overview track enables
you to see whether a recording exists from a camera that is not currently supplying
an image. The camera names are listed in alphabetical order using the
characteristic computer listing principle (e.g. Cam 1, Cam 10, Cam 11, Cam 2,
Cam 22, etc.).
The display is scaled over the set time period. Periods themselves can be set in
stages (see popup-menu above camera list). There are also the following stages in
addition to the setting "Overall duration" which shows the complete period of all
stored recordings: "4 weeks", "1 week", "2 days", "1 day", "12 hours", "5 hours",
"2 hours", "1 hour", "15 minutes" and "3 minutes".
Each field of the diagram describes a time window of greater or smaller size
depending on the set time range. Clicking with the left mouse key on a field
provides the corresponding image. In this case, SISTORE MX seeks an image that
was recorded at the start of the time period described by the selected field. If no
image has been stored at that time, SISTORE MX searches for an image that is as
close as possible to the required time (marking "out of focus" at bottom right edge).
Slight inaccuracies are possible when clicking on a field depending on the
resolution and selected time range.
The actual displayed time is marked in the diagram by a vertical line (colour:
magenta). The configuration of the current display can be rearranged using the
button Update at bottom left.
The corresponding fields of the diagram are also marked in colour during recording
(no marking = no recording). Colour marking is differentiated as follows:
Blue: image recording (at least 1 image) has taken place in the time window
defined by this field / Pre-trigger phase
Green: as blue, though with movement detection instead / Post-trigger phase
Red: at least 1 alarm image has been recorded
Yellow: write protected records
A click with the left mouse key and dragging the mouse to the right or left while
holding the mouse key pressed causes so-called "scratching". This means that
during the movement, the display always shows the image corresponding to the
actual mouse position and therefore to the current moment in time.
