Playback

Siemens Building Technologies

Fire Safety & Security Products 01.2008

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.

17.7 Timeline display

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:

z Blue: image recording (at least 1 image) has taken place in the time window

defined by this field / Pre-trigger phase

z Green: as blue, though with movement detection instead / Post-trigger phase

z Red: at least 1 alarm image has been recorded

z 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.
