Iris adjustment
Select Enable automatic iris adjustment to automatically compensate for changing light conditions. This option is not available
if a fixed iris is used.
Day/Night
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” infrared light. The
image is shown in black and white when the IR cut filter is off.
If using automatic Exposure control , set the IR cut filter to Auto to automatically switch between On and Off according to the
lighting conditions.
The Day/Night shift level bar helps determine when the camera will shift from day mode to night mode. Normally, the camera
automatically changes mode from day to night when very dark (level 100 in the slider). By setting Day/Night shift level to a
lower value, the camera will change to night mode earlier.
View Area
A view area is a cropped part of the full view. Each view area is treated as a video source in Live View and has its own video
stream and PTZ settings.
When setting up a view area it is recommended that the video stream resolution is the same size as or smaller than the view area
size. Setting the video stream resolution larger than the view area size implies digitally scaled up video after sensor capture,
requiring more bandwidth without adding image information.
To enable, go to Video > Camera Settings and select Enable View Areas .
To add a new view area:
1. Go to Video > View Area .
2. Click Add .
3. The new view area appears under Selected view area . Enter a descriptive name in the Name field.

5. A new view area covers the whole image. Use the mouse to move and resize the view area.
6. Select Enable PTZ to enable digital PTZ for the view area.
7. Click Save to save the settings.
To modify a view area, select the view area in the list and modify the settings as required. Click Save .
To remove a view area, select the view area and click Remove .
Note
The PTZ functionality is useful during installation of the Axis product. Use a view area to crop out a specific part of the
full view.
Overlay
Overlays are used to provide extra information, such as forensic video analysis or during product installation and configuration.
Overlays are superimposed over the video stream.
An overlay text can display the current date and time, or a text string.
When using a text string, modifiers can be used to display information such as the current bit rate or the current frame rate.
