AXIS Q1775-E Network Camera
Video and Audio
White Balance
To change this setting go to Setup > Video & Audio > Camera Settings
White balance is used to make colors in the image appear the same regardless of the color temperature of the light source. The Axis
product can be set to automatically identify the light source and compensate for its color. Alternatively, select the type of light
source from the drop-down list. For a description of each available setting, see the online help
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. Disable WDR in low light conditions for optimal exposure.
Exposure Settings
Exposure control - These settings is used to adapt to the amount of light used. Automatic is the default setting and it can be
used in most situations. The shutter speed is automatically set to produce optimum image quality. Use Manual if you have special
requirements for the exposure setting and wish to lock it. Select the desired exposure time from the drop-down list.
Max exposure time - Select the maximum exposure time from the drop-down list. Increasing the exposure time will improve image
quality, but decrease the frame rate. There may also be an increase in motion blur.
Allow slow shutter - Select Allow slow shutter to let the camera decrease the shutter speed in low light to improve image brightness.
Enable Backlight compensation - Select Enable Backlight compensation if a bright spot of light, for example a light bulb, causes
other areas in the image to appear too dark.
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 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
Important
The autofocus behavior is affected by factors such as light conditions, contrasts in the scene, and objects moving in and out. In
these conditions or scenes, a manual focus could be preferable to enhance performance and allow the camera to focus faster.
Autofocus enabled - Autofocus enables the camera to focus although the distance to different objects of interest is constantly
changing. Whenever the camera's pan/tilt/zoom position is changed, the autofocus performs a search to find the ideal focus point.
Automatic focusing is enabled by default. If the focus position is changed manually using the focus bar, autofocus will be disabled
even if enabled in Image Settings. In this case, use the PTZ control panel to enable autofocus, see page 14. If required, the focus
control can be disabled under PTZ > Advanced > Controls.
Defog - Enable this feature from Video & Audio > Camera Settings to counter the effects of foggy weather and get a clear image.
Noise reduction - Set to On to enable noise reduction. Noise reduction may increase the amount of motion blur.
