Imaging Tab
Use the Imaging tab to change the camera’s general image settings, adjust the camera exposure, program the focus mechanism, adjust the tone
map settings to increase scene detail, or define window blanking privacy areas.
General Imaging Settings
General imaging settings include adjustments for camera orientation and digital processing. The Orientation settings reconfigure the image
180 degrees horizontally and 180 degrees vertically. Use these settings when installing the camera in an inverted position. If the orientation is
not adjusted, the image will display upside down and mirrored.
Digital processing settings include 3D noise reduction and auto white balance options as well as slider controls to adjust the camera’s
sharpness, saturation, hue, contrast, brightness, and wide dyananic range (WDR) strength.
The WDR strength control offers a balance between image detail and image contrast. A lower WDR strength increases contrast in most scenes,
but with reduced detail. A higher WDR strength ensures greater detail, but may result in reduced contrast and a washed-out look to the image.
3D noise reduction reduces noise and creates the best image quality for most scenes, but can obscure details in moving objects. If moving
objects appear blurrier than the rest of the scene, turn 3D noise reduction off.
Auto white balance settings define how the camera processes video images to render true colors in a scene. When set to On, white balance
automatically adjusts to deliver the best possible image in scenes with changing lighting conditions or in scenes with more than one type of light
source. For example, scenes that benefit from white balance correction are outdoor scenes, indoor scenes that include a window or door that
opens to the outdoors, or indoor scenes that include both incandescent and fluorescent lighting.
Exposure Settings
The exposure settings page includes adjustments for exposure, flicker, and day and night options.
Exposure is the amount of light detected by the camera sensor. A scene with correct exposure settings has adequate detail and contrast between
white and dark values. An image with too little or too much exposure eliminates detail in the scene.
Flicker correction reduces rolling shutter flicker in images with reduced dynamic range. Auto flicker correction automatically reduces rolling
shutter flicker in scenes with reduced dynamic range, but it does not reduce picture flicker in scenes with high dynamic range. The On setting
reduces rolling shutter picture flicker, and it dramatically reduces the amount of dynamic range in the image. The default setting Off maintains
the maximum amount of dynamic range in the image, but it can produce rolling shutter picture flicker in scenes with florescent or other
oscillating light sources.
Day/night settings control the position of the IR cut filter, which determines the color or black-white setting of the camera. Day/night settings
change depending on the exposure settings.
Focus Settings
Focus sets the back focus to the center focal point of the scene. The camera can be configured to back focus automatically or manually. Auto
focus automatically back focuses the camera on the subject in the center of the scene. Manual focus turns off the auto focus mechanism and
locks the camera at a user-specified position. The manual focus setting is recommended only for indoor applications that have a single,
unchanging primary light source. The Focus page also includes Full Range Auto-Focus and Factory Defaults.
Tone Map Settings
Tone map balances the brightest and darkest sections of a scene to produce an image with more balanced lighting and more detail. This is
accomplished, in part, when the device maps the 10-bit input sensor data (0 to 1023 bits) into 8-bit output RGB values (0 to 255 bits).
Window Blanking Settings
Window blanking is used to conceal user-defined privacy areas. A blanked area appears on the screen as a solid gray window. The camera can
handle up to sixteen blanked windows as long as the total blanked area does not exceed 50 percent of the field of view.
