Administrating the Camera

Setting the Object Detection Function — Object detection Menu

Note

You cannot set all four windows as Inactive windows.

Be sure to set one or more windows as Active

window(s).

Moving object detection indicator

This indicator shows the threshold level for outputting

an alarm and a graph of the motion level in the window.

An alarm is output when motion that exceeds the

threshold level is detected in the window.

Note

You can change the threshold level using the Threshold

setting slider bar at the bottom of the display, but you

cannot set the threshold level individually for each

window.

Threshold setting slider bar

Set the threshold level of moving object detection that is

common to all the windows.

The threshold level is used to judge whether or not there

has been any motion in the camera image. When the

level shown in the moving object detection indicator has

exceeded the threshold level, the camera judges that

there has been a motion.

An alarm is output when there is a motion exceeding the

set threshold level in one of the active windows.

Object size

Select the minimum size of a detectable object from L

(Large), M (Medium) and S (Small).

Each option represents the corresponding size below:

L: 64 × 64 dots

M: 32 × 32 dots

S: 8 × 8 dots

Tip

The monitor display is 640 × 480 dots. Size L is 1/10 the

width of the monitor display.

OK button

Click to confirm the settings and send the set values for

the selected position to the camera.

Note

Although the indicator quickly responds to the setting

being performed as you change the size of a window or

a parameter, you need to click the OK button to confirm

the setting. The setting will be cancelled if you do not

click the OK button.

To set the moving object detection

function

Set the moving object detection function as follows:

Select Moving object for Detection.

The setting items for moving object detection

appear.

Check the Window 1 check box.

The Window 1 frame appears on the monitor

display.

Adjust the position and size of Window 1.

Drag Window 1 to move it and change its size.

Set the active or inactive windows.

Select Active to set Window 1 as an active area, or

Inactive to set it as an inactive area.

Note

If an active window and inactive window overlap,

the overlapped portion will be regarded as an

inactive area.

Set the function for Windows 2 to Windows 4.

Repeat steps 2 to 4 for each window.

Select the object size for Object size.

Select a larger size if a small noise may be detected

as a motion by mistake.

Adjust the Threshold setting slider bar to set the

threshold level at which the camera executes

detection.

Adjust the detection level while observing the

moving object detection indicator and actually

shooting a moving object.

Click OK.

The moving object detection settings for the

selected position are confirmed.
