IR cut filter
The IR cut filter prevents infrared (IR) light from reaching the image sensor. In poor lighting conditions, for example a t night, o r
when using an IR lamp, set the IR cut filter to Off. This increase s 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,settheIRcutfilter to Auto to automatically switch between On and Off accordingtothe
lighting conditions.
White balance
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 he lp
.
Wide Dynamic Range
Wide dynamic range can improve the exposure when there is a considerable contrast between light and dark areas in the image.
Exposure Settings
Configure the exposure settings to suit t he image quality requirements in relation to lighting, frame rate and bandwidth
considerations.
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.
The Exposure control setting is used to adapt to the amount of light used. Select one of the following m odes:
• Auto is the default settings and can be used in most situations. Shutter speed, Iris and Gain are automatically set to
produce optimum image appearance for differe nt lighting situations.
• Manual Shutter allows you to manually adjust the shutter spee d. Iris and Gain are set au tomatica lly.
• Manual Iris allows you to manually adjust the iris opening in the lens. Shutter speed and Gain are set automatically.
• Manual allows you to manually adjust Shutter speed, Iris and Gain.
Shutter speed - A slo we r speed in dark conditions will help to p roduce a brighter image, but will produce fewe r frames per second,
which may cause blurry images during motion.
Iris - A larger F-value means less light sensitivity, but a larger depth of field.
Gain - M easured in decibels (dB), gain describes the amount of amp lification applied to a signal, in this ca se the visual information
in the image . A high leve l of amplification may provide a bet ter image in very low light situations. A high gain will als o increase
theamountofimagenoise.
Maxexposuretime-Increasingtheexposuretimewillimproveimagequality, but decrease the frame rate. There may also be
an increase in motion blur.
Max gain - Max gain limits the amount of gain that can be applied to the image in Exposure control modes with automatic
gain adjustment.
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 r equirement, select a predefined area.
Image settings
Autofocus enabled - Automatic focusing is enabled by default. If the focus p osition 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
9 . If required, the focus control can be disabled under PTZ > Advanced > Controls.
