General Image Settings

 

Open the General Event Settings dialog to define the basic settings for image control in the camera.

Notes:


Description of Parameters

Lens Select the lens that you want see on the Live and Guest pages or set the picture-in-picture mode to combine the images of both lenses (only for dual-lens cameras).
Right Right lens (factory default setting, usually the wide-angle lens)
Left Left lens (usually the tele lens)
Both Combines the images of both lenses and displays them side-by-side (left: left lens, right: right lens, as seen by the camera)
RiL Displays a small image (160x120 mm) from the right lens in the bottom right corner of the image from the left lens. This requires a resolution of 640x480.
LiR Displays a small image (160x120 mm) from the left lens in the bottom right corner of the image from the right lens. This requires a resolution of 640x480.
Image Size Select the display size of the image.
Dual images automatically require twice the width.
Frames per Second Number of images per second that are recorded by the camera. When long exposure times are necessary to comply with poor lighting conditions, the frame rate decreases.
Sharpness

In order to improve image quality, you can adjust the sharpness control value. A lower value results in a smoother (less crisp) image.
The factory default setting is 4.

If the value is too high, image this may result in image disturbances.

Mirror image Using this parameter, you can mirror the image (but not the displayed text) vertically, horizontally and along both axes simultaneously.
Image rotation

Using this parameter, you can turn the image (but not the displayed text) by 180°. It is recommended you use this feature only for indoor applications..

Attention:

  • When mounting the camera upside-down in outdoor scenarios, the camera is not IP65-certified any more. In this case, you will void the warranty!
  • When mounting the camera upside-down in outdoor scenarios, humidity from natural condensation cannot exit the camera properly. In this case, you will also void the warranty!
Night Camera Level (NI/DY)

The camera automatically switches between its day and night lenses when the illumination falls below or exceeds the level set here. The higher the illumination value, the earlier the camera switches to the night lens.

Notes:

  • This parameter is available only for Secure models.
  • Modifying this parameter makes sense only when your camera is equipped with a day and a night lens.
  • In the Camera Selection section of the dialog, select the day lens (normally the right lens).

To determine the best possible value for defining the night camera level, proceed as follows:

  • In the Text & Display Settings dialog, click on the More button to display all options of the dialog.
  • In the same dialog, set the Text Display parameter to On.
  • In the Comment text box, enter the ^Ir placeholder. The camera now displays the current illumination rate in percent on the live image.
    (See also Placeholders for Dynamic Image Text.)
  • Set the Level Meter parameter to Bar, and select Illumination as source for the level meter. The camera now displays the current exposure rate as a red bar on the live image. The value for switching to the night lens is displayed as white vertical line.
Background noise suppression

Growing darkness results in image quality getting poorer. This effect is called image (or dark) noise.

The Dark Noise Suppress parameter minimizes this effect.

Obscure Image Area (OA)

In some applications, certain image parts need to be obscured.

Notes:

  • This parameter is available only for Secure models.
  • When running the camera in the time-controlled mode, you may define a period of time during which certain image areas are obscured.
  • In order to obscure several image parts, you need to define several windows (= lines).

Every line in the definition box (e.g. 0,270,190,100,100,2) represents one window. The image coordinates' origin is the lower left corner of the image.

Hint: For defining a new or additional window, follow the instructions in the Graphically Entering Image Areas online help topic.

Format of one line:
Image sensor, pos. x,pos. y, width, height, type

Parameters of one configuration line:

Image sensor 0 = right
1 = left
Pos. x Number of pixels from the left edge of the image to the left edge of the window
Pos. y Number of pixels from the lower edge of the image to the lower edge of the window
Width Width of the window
Height Height of the window
Type 0 = filled rectangle
1 = crossed-out frame
2 = tiled image area

Store the Configuration

Click on the Set button to activate your settings and to save them until the camera is rebooted.

Click on the Close button to close the dialog. While closing the dialog, the system checks the entire configuration for changes. If changes are detected, you will be asked if you would like to store the entire configuration permanently.
