Triggered Capture of Videos and Photos

Calendar

The calendar gives an overview on the number of events which have been registered for a specific day:

Clicking on a red field navigates to the Events display for this specific day.

You can change the active month using the date control and navigation arrows, or return to the current month with the Now button.

Download Log

You can download the Log file including a timeline of all events and associated actions.
Note that only those triggers and their associated actions will be included in the log, for which the control parameter event_log has the value "True".

Cleanup

The Cleanup button can be used for removing old events.
This requires that the process is stopped.

After pressing the button, a confirmation is required:

The Retention Period for cleanup, shown in this confirmation, has been specified on the Trigger/Control page.

For all events older than the Retention Period, cleanup will

• remove all log file entries
• delete all photo and video files
• delete related database entries

Events

Event Details are shown in the Event Viewer for a specific day:

In the top area, you may

• change the active day using the date control or the arrow buttons.
  Single arrows shift by day, double arrows by week.
  In each case the starting hour is set to 00:00h.
• change the start time from which on events will be shown.
  Here, single arrows shift by a quarter of an hour, double arrows by an hour.
• You can select whether you want to see videos, photos, both or none.
  In case of videos, the first photo is always shown instead of the video on the left side, however clicking on the photo will open the video viewer.
• whether a video or a photo is represented by the small picture can be distinguished by information on the video length.

Selecting a video or photo shows it in the detail area on the right side.

The Event Card for each event

shows, from top to bottom:

• Event Type
• Event date
• Event time
• Event trigger
• Event trigger algorithm
  Mean Square Diff
  Frame Diff.
  Optical Flow
  BG Subtraction
• Trigger parameter (see Motion tab)
  cam : Camera Num by which motion was detected
  roi : Index of the Region of Interest in which motion was detected
  NOTE: Motion detection analysis is stopped whenever motion has been detected in one of the RoIs. The index of this ROI is reported here.
  msd : Mean Square Threshold
  BBox_thr : Bounding Box Threshold
  IOU_thr : IOU Threshold
  Motion_thr : Motion Threshold
  Model : Background Subtraction Model (1=MOG2, 2=KNN)

You may use the information to fine tune the algorithm parameters on the Motion tab.

When Photos/Videos with RoI/RoNI has been activated, borders of RoIs/RoNIs are shown on photos and videos (for "Mean Square Diff" not no videos):

• Red borders represent Regions of Interest where motion was detected first.
• Green borders represent the other specified *Regions of Interest.
• Blue borders represent *Regions of NO Interest.

In case that photos have been taken together with videos, this is represented as shown below.
Videos show the video length in the footer.
