The Detection zone object is used to register and configure smart video detectors. The settings panel of the Detection zone object is shown in the figure:

The table describes the parameters of the settings corresponding to the elements of the settings panel of the Detection zone object:

Boolean type

Clear

Set—on alarm received from the selected detector, an alarm is generated on the camera, and automatic recording of the video signal is performed

Clearalarm isn't generated on the camera, and automatic recording of the video signal isn't performed on the alarm received from the selected detector

Set the checkbox

Sets the Armed always state for the selected detector

Boolean type

Clear

Set—the detector is always in the Always armed state

Clearthe operator can disarm the detector

9

The Sensitivity
slider

Set the slider in the position

Sets the setting parameter of the same name for the selected detector. Depends on the type of the selected detector.

  • Motion detector

The value of this parameter corresponds to the minimum value of the averaged brightness of the moving object, at which the detector generates an event only at its motion and not at the video signal noise (including snow, rain, and so on). The HIGHER the sensitivity value, the more sensitive the detector is.

  • Focus detector

The value of this parameter characterizes the minimum degree of accuracy loss, expressed in the difference between the average number of outlines and the number of outlines in the incoming frame at which the detector must generate an event.

  • Stability detector

The value of this parameter characterizes the minimum degree of accuracy loss, expressed in the difference between the average number of outlines and the number of outlines in the incoming frame at which the detector must generate an event.

  • Background change detector

This parameter characterizes the deviation of the integral brightness of the frame from the average value at which the detector must generate an event.

  • Blind detector

This parameter corresponds to the rate of illumination of the video expressed in the difference between the positions of medians of the brightness chart of the incoming frame and the reference illumination frame at which the detector must generate an event.

  • Cover detector

This parameter corresponds to the rate of narrowing of the brightness chart of the frame, that is, the estimation of the frame filling with gray color, at which the detector must generate an event.

  • Infrared detector

The value of this parameter corresponds to the minimum value of the averaged brightness of the moving object, at which the detector generates an event at its motion

NA

Average

NA

10

The Contrast
slider

Set the slider in the position

Sets the minimum contrast of the object at which the detector generates an event at its motion. The HIGHER the specified contrast value, the more different the neighboring b/w elements must be so that the detector considers them as different objects.

Note. It isn't used for all detector types

NA

Average

NA

11

The Filter
slider

Set the slider in the position

Sets the setting parameter of the same name for the selected detector. Depends on the type of the selected detector.

  • Motion detector, infrared detector

The value of this parameter corresponds to the threshold of color processing of objects, at which the detector must generate an event. The HIGHER the filtering, the more different the neighboring elements (pixels) of the image must be so that the detector considers them as different objects.

  • Background change detector, Stability detector

The value of this parameter corresponds to the contrast threshold of the detected object.

Note. It isn't used for other detector types

NA

Minimum

NA

12

The Size
slider

Set the slider in the position

Sets the setting parameter of the same name for the selected detector. The value of this parameter corresponds to the minimum size of the detected object relative to the frame size.

Note. It isn't used for all detector types

NA

Average

NA
