AXIS Q6044-C PTZ Dome Network Camera
Video
Max gain - Measured in decibels (dB), gain describes the amount of amplification applied to a signal, in this case the visual information in the image. A high level of amplification may provide a better image in very low light situations. A high gain will also increase the amount of image noise.
Exposure zones - This settings determines which part of the image is used to calculate the exposure. For most situations, the Auto setting can be used. For particular requirement, select a predefined area.
IR cut filter - The IR cut filter prevents infrared (IR) light from reaching the image sensor. In poor lighting conditions, for example at night, or when using an external IR lamp, set the IR cut filter to Off. This increases light sensitivity and allows the product to “see” infrared light. The image is shown in black and white when the IR cut filter is off. Set the IR cut filter to Auto to automatically switch between On and Off according to the lighting conditions.
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
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 13. 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
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 Use 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.
