The Show
checkbox

Set the checkbox

frame border of an object in the camera field of view.

Boolean type

Set—the object frame border is displayed in the

The Alarm
checkbox

Enables alarm generation on the camera and

automatic recording of the video signal from the camera

upon alarms of the selected detector

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

Clear—alarm

isn't generated on the camera, and

automatic recording of the video signal

isn't performed on the alarm received from the selected detector

The Armed always
checkbox

Set the checkbox

Arms the

detector

Boolean type

Clear

Set—the detector is always in the Always armed state

Clear—the

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. 
The setting 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

.

• 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

13

The Delay between MD_INFO (ms)
field

Enter the value

in the field

Sets the time period in milliseconds between the MD_INFO events

of the CAM_ZONE

detector in the

event viewer (if the MD_INFO event is

included in ddi)

Non-negative integer

NA

>=0

Sets the threshold of difference between the brightness of the pixel in the current frame and the background

Sets the maximum permissible percentage of the stabilized frame pixels that differ from the background by more than the value in

the Stability detection sensitivity field

, exceeding which the

system starts monitoring the alarm state

Sets the maximum permissible percentage of the stabilized frame pixels that differ from the background by more than the value in the Stability detection sensitivity

 field before reaching which the frame is considered stable

Sets the time period in seconds during which the Upper stability limit must be exceeded to generate an alarm
