AXIS Q6044-C PTZ Dome Network Camera

Video

Day/Night shift priority - Use the Day/Night shift priority bar to determine when the camera shifts into either day mode or night mode. By default, the camera will automatically change from day to night mode at a pre-defined level which corresponds to light conditions. By dragging the bar handle towards the sun, the camera will change to day mode earlier and change to night mode late.

Image Settings

Autofocus enabled - Automatic focusing is enabled by default. If the focus position is changed manually using the focus bar, autofocus will be disabled even if enabled here. In this case, use the PTZ control panel to enable autofocus, see PTZ Controls, on page 14. If required, the focus control can be disabled under PTZ > Advanced > Controls.

Auto defog - The product will detect fog and automatically filter it out to get a clear image. Select the level of fog removal from the drop-down list. High implies that maximum fog removal is applied and off implies no fog removal. Auto defog can be activated incorrectly in scenes with low contrast, high light level variations or when auto focus is slightly off. This can affect the image quality by for example, increasing image contrast. Also, too much brightness can negatively impact the image quality when defog is active.

Noise reduction - Set to On to enable noise reduction. Noise reduction may increase the amount of motion blur.

Stabilizer - When monitoring environments that are subject to vibrations (e.g. traffic control), images may appear to be unsteady. Select the frequency, High or Low, that gives the best improvement in image quality. Enabling the stabilizer will limit the digital

zoom. See the online help for more information.

Image freeze on PTZ - Select All movements to freeze the image while the camera is moving during a pan, tilt or zoom operation. Once the camera reaches its new position, the view from that position is shown. Presets freezes the image only when the camera moves between preset positions.

Overlay

Overlays are used to provide extra information, for example for forensic video analysis or during product installation and configuration. Overlays are superimposed over the video stream.

An overlay text can display the current date and time, or a text string. When using a text string, modifiers can be used to display information such as the current bit rate or the current frame rate. For information about available modifiers, see File Naming &

Date/Time Formats in the online help .

It is also possible to display text when an action rule is triggered, see Using Overlay Text in an Action Rule.

To enable overlays:

1.Go to Video > Video Stream and select the Image tab.

2.To include an overlay image, select Include overlay image at the coordinates. The overlay image must first be uploaded to the Axis product, see Overlay Image.

3.To include date and time, select Include date and Include time.

4.To include a text string, select Include text and enter the text in the field. Modifiers can be used, see File Naming &

Date/Time Formats in the online help .

5.Define text overlay characteristics in the relevant fields.

6.Click Save.

To modify the date and time format, go to System Options > Date & Time. See Date & Time, on page 47.

Overlay Image

An overlay image is a static image superimposed over the video stream. The image, for example company logo, is used to provide extra information or to mask a part of the image.

Since it is static, the position and size of an overlay image will remain the same regardless of resolution and Pan/Tilt/Zoom movements. To set up a dynamic mask, which will always mask the specified part of monitored area, see Privacy Mask.
