AXIS Q6035 PTZ Dome Network Camera
Video and Audio
Wide Dynamic Range
Wide dynamic range can improve the exposure when there is a considerable contrast between light and dark areas in the image. Enable WDR in intense backlight conditions. The different WDR settings adjust for various amounts of contrast in the image. Use a higher WDR number for a higher contrast. Disable WDR in low light conditions for optimal exposure.
Exposure Settings
Configure the exposure settings to suit the image quality requirements in relation to lighting, frame rate and bandwidth considerations.
Exposure control - These settings is used to adapt to the amount of light used. Automatic is the default settings can be used in most situations. The shutter speed is automatically set to produce optimum image quality.
Max exposure time - Select the maximum exposure time from the
Enable Backlight compensation - Enable this option if a bright spot of light, for example a light bulb, causes other areas in the image to appear too dark.
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.
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.
Day/Night
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 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.
If using automatic Exposure control, set the IR cut filter to Auto to automatically switch between On and Off according to the lighting conditions.
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 10. If required, the focus control can be disabled under PTZ > Advanced > Controls.
Noise reduction - Set to On to enable noise reduction. Noise reduction may increase the amount of motion blur.
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 
.
To enable overlays:
1. Go to Video & Audio > Video Stream and select the Image tab.
