Camera Settings

The Video > Camera Settings page provides access to advanced image settings for the Axis product.

Image Appearance

Increasing the Color level increases the color saturation. The value 100 gives maximum color saturation. The value 0 gives a black and white image.

The image Brightness can be adjusted in the range 0–100, where a higher value produces a brighter image.

Increasing the Sharpness can increase bandwidth usage. A sharper image might increase image noise especially in low light conditions. A lower setting reduces image noise, but the whole image will appear less sharp.

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 help.

Wide Dynamic Range

Wide Dynamic Range (WDR) processing balances the brightest and darkest sections of a scene to produce an image that is balanced in lighting to provide more detail. Wide dynamic range can improve the exposure when there is a considerable contrast between light and dark areas in the image. There are three different WDR modes:

WDR 1 - contrast

WDR 2 - double exposure

WDR 3 - contrast and double exposure

The different WDR settings adjust for various amounts of contrast in the image. Use a higher WDR number for a higher contrast. 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. Checking Allow slow shutter decreases 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.

Highlight Compensation - The Axis product will detect a bright light from a source such as a torch or car headlights and mask that image area. This setting is useful when the camera operates in a very dark area where a bright light may overexpose part of the image and prevent the operator from seeing other parts of the scene.

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”
