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.

shows, from top to bottom:

  • Event Type

    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.

Photos/Videos with ROI/RoNI

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.
