AXIS Q1604–E Network Camera
Video and Audio
Capture Mode
The capture mode setting reduces image flicker in fluorescent light environments as image data is sampled at a rate that matches the
local power line frequency.
Capture mode is set the first time the product is accessed. Select the capture mode with the power line frequency (50 Hz or
60 Hz) used at the location of the Axis product and click OK.
When using 50 Hz, the maximum frame rate is limited to 25 fps.
Note
Power line frequency is different in different geographic regions. In the Americas, 60 Hz is usually used; most other parts of
the world use 50 Hz. Local variations may apply, always check with the local authorities.
Changing capture mode when the product has been configured is not recommended as most other settings will be either removed
or reset, for example:
1. Go to Setup > Video & Audio > Camera Settings.
2. Select the new capture mode.
3. Click Save.
4. Review and reconfigure all settings, for example:
- Stream profiles
- Motion detection windows
- Privacy masks
- Image overlays
- Exposure zones
- White balance windows
- Action rules
- Settings in uploaded applications
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.
The Contrast changes the 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 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
The white balance windowis enabled for the Automatic and Automatic outdoor options that appear in the White balance drop-down
list. Select one of the options from the drop-down list to set the white balance window properties. Select Automatic to use the
default settings for the Automatic and Automatic outdoor options (in the White balance drop-down list). Select Custom to manually
set a reference window for white balance in the view area.
