AXIS P33 Series - Video & Audio

Contrast - Adjust the contrast of the image by raising or lowering the value in this field.

White balance

This is used to compensate for the different colors present in different light sources, to make the colors in the image appear

the same. The network camera can be set to automatically identify the light source and compensate for its color. Alternatively,

the type of light source can be manually selected from the drop-down list. See the online help files

for a description of

each available setting.

Wide Dynamic Range

Wide dynamic range improves the exposure when there is a considerable contrast between light and dark areas in an image.

Note: Wide dynamic range is only possible when the Exposure control setting is set to Automatic.

Exposure Settings

Configure the exposure settings to suit the image quality requirements in relation to lighting, frame rate and bandwidth

considerations.

Exposure value - Use this slidebar to fine tune the exposure. Increasing the exposure will improve image quality at the

expense of the total frame rate. There may also be an increase in motion blur.

Exposure control - Set to Automatic for optimal exposure settings automatically, for example brightness and noise.

Flicker-free 50 or 60 Hz is used to remove flicker which can be caused by fluorescent and other light sources. The Hold

current option locks the current exposure settings.

Enable Backlight compensation - Backlight compensation makes the subject appear clearer when the image background is

too bright, or the subject too dark.

Exposure zones - This setting determines which part of the image is used to calculate the exposure. The Auto setting can be

used in most situations, but for particular requirements, select Defined and click the Edit button to open the Exposure

Windows dialog to custom define the exposure zone.

IR cut filter - Set this filter to Off to allow the camera to 'see' infrared light, making the image clearer in low light

conditions, e.g. at night or if using an infrared lamp. If set to Auto, the camera will automatically switch between IR cut filter

On and Off, according to the current lighting conditions. Note that if this IR cut filter is set to Off, the image is in black and

white.

Exposure priority - This defines the balance between image quality and the frame rate. When Motion is prioritized, motion

blur is minimized, but the image quality may be reduced with a higher frame rate. A prioritized Low noise will provide better

image quality with a lower frame rate.

Shutter - A smaller value means less motion blur, but requires a well lit scene. A larger value will allow more light in the

camera so that even a low lit scene can produce a good image, but at the expense of increased motion blur.

Gain - A lower value means less noise; in dark situations this can lead to a very dark image. A larger value means more

amplification making it possible to observe a dark scene, but with increased noise. When Motion is prioritized the shutter

time is kept as low as possible. When Low noise is prioritized the gain is kept as low as possible. Setting min/max to the same

values is equivalent to setting a fixed value.

Enable automatic iris adjustment - This should always be set to Enabled, except during focusing, or when using a fixed iris

lens.
