Boolean type

Clear

Set—the 

Detection zone is disabled and

Clear—the Detection zone object is enabled and

used

4

The Camera

drop-down list

Select the value from the list

The Detection

drop-down list

Select the value from the list

Sets the type of the used detector

Names of the detectors in the system

6

The Show
checkbox

Set the checkbox

Displays

the frame border of an object in the

camera field of view.

This parameter is active only

when you select the following detectors

from the

Detection drop-down list: motion, infrared

Boolean type

Set—the object frame border is displayed in the

video surveillance area

Clear—the object frame border

isn't displayed in the

video surveillance area

7

The Alarm

checkbox

Set the 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

8

The Armed always

checkbox

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

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. 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

13

The Direction
set of

buttons

Press the arrow

button

Sets the direction of search for the motion detector

of object movement in the frame

All directions are

included: up, down, to the left, to the right, up and to the left, up and to the right, down and to the left, down and to the right

Up, down, to the left, to the right, up and to the left, up and to the right, down and to the left, down and to the right

The Delay between MD_INFO (ms)
field
