Image Appearance

Increasing the Color level increases the color saturation. The value 100 gives maximum color saturatio n. 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 bandw idth 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.

The Contrast changes t he relative difference between light and dark. It can be adjusted using the slidebar.

White balance

White balance is used to make colors in the image appear the same regardless of the color temper ature 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 de scription of each available setting, see the online help

Exposure Settings

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

considerations.

Exposure value - Click in the bar to ﬁne-tune the exposure.

Enable Backlight compensation - Enable this option if a bright spot of light, for example a light bulb, causes other areas in

the image to appear too dark.

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.

Exposure priority - When Motion is prioritized and maximum Shutter time is set to a small value, m otion b lur in the image is

minimized. This can be useful for recognition of moving objects such as people and vehicles. However, prioritizing motion may cause

an increase i n image noise, especially in low light situations. When Low n oise is prioritized and Gain is set to a small value, image

noise is minimized. The ﬁle size is reduced, which c an be useful if storage space or bandwidth i s limited. However, prioritizing low

noise may result in a ve ry d ark image, especially in low light situations.

Overlay

Overlays can be used to provide extra information and are superimposed over the video image. With overlay text it is possible to

include date and time or view the current b

it rate as overlay text.

To include the current bit rate as ov

erlay text go to Video & Audio > Video Stream > Overlay Settings,selecttheInclude text check

box option, and enter the overlay code in the ﬁeld. See the online help

for supported formats.

Audio Settings

The audio functi

onality for each video stream is enabled under Video & Audio > Video Stream > Audio.

Audio Input

Input gain - Control the volume (dB Full Scale) of the audio input. If the sound is too low, choose a higher dB, to amplify the

sound. If the sound is too high, choose a lower dB. The Level bar gives a visual repre s enta t ion o f the audio signal level in dB

relat

ive to the full-scale input level.

• Green — the signal is at a good level.

• Yellow — the signal is becoming distorted.

• Red — the signal is distorted.
