Motion detector🔗

Motion detector parameters can be set up on the Motion detector tab.

Below is the description of controls located on the tab.

Video stream for analysis: Determines which stream will be used for software motion detection on Eocortex server.

Set up the stream: Switches to the Connection tab, which allows selecting the stream to be recorded to the archive.

Motion detector: Enables motion detector support.

Detector type: Determines which motion detector will be used:

  • Eocortex: Software motion detector on Eocortex server.

  • On camera: Camera inbuilt motion detector.

Warning

To use the motion detector built into the camera, it is necessary that the motion detector is existing on the camera and the Eocortex supports it.

Warning

When using the motion detector built into the camera, the Eocortex video analytics becomes unavailable.

Clicking the Checking button opens the motion detector test window. In this window, detected moving items will be outlined with a colored border.

By clicking the Set up zones and sizes button will open the window of setting up detection zones and minimum sizes of the objects to be detected.

Enable motion start/end events: Enables generation of the corresponding events, for example, for using them in scenarios.

Optimize for archive recording: Ensures that recording to the archive will be performed even if there is a brief motion cessation in the frame.

Warning

Turn on the Optimize for archive recording option may reduce the accuracy of the following modules:

  • Auto Zoom

  • Sabotage Detection

  • Crowd Monitoring

  • Personnel Activity Monitoring

  • Shelf Fullness Check

  • People Counting

  • Search for Objects

  • Face Detection

  • Traffic Density Heat Map

  • Tracking

Warning

False motion (weather conditions, swaying leaves, etc.) may increase the archive size.

Detection frequency: Determines the frequency of video stream analysis for detecting motion in the frame:

  • Optimal frequency: Video stream analysis and motion detection will be performed with the frequency set automatically in accordance with the following rules:

    • If at least one video analysis module is enabled on the camera, the analysis will be performed with the frequency of 10 fps;

    • If no video analysis module is enabled on the camera, the analysis will be performed with the frequency of 5 fps for MJPEG, and for H.264, H.265 and MPEG-4 the frequency will be chosen automatically within the range of 0.4 – 5 fps.

  • Only by key frames: Only the key frames will be analyzed for H.264, H.265 and MPEG-4 codecs.

  • Constant frequency: The analysis will be performed with the set frequency.
