AXIS Q6155-E PTZ Dome Network Camera
Video
2. Use the slider to set the Priority between Low motion blur and Low noise. When prioritizing low motion blur (slider
all the way to the right) the camera automatically increases gain as brightness decreases. When the gain reaches the
set maximum gain for low light, the camera will decrease shutter speed until the set maximum shutter for low light is
reached. This is the default priority setting for low light.
3. Select the Max gain value from the drop-down list. This defines the upper limit for gain in the context of normal light.
4. Max fast shutter sets shutter speed limit in normal light conditions. Depending on the scenario, the shutter speed limit
may need to be defined. This is done through System Options > Advanced > Plain Config.
Image Settings
Noise reduction - Set to On to enable noise reduction. Noise reduction may increase the amount of motion blur.
Stabilizer - When monitoring environments that are subject to vibrations (e.g. traffic control), images may appear to be unsteady.
Select On to steady the image. See the online help
Image freeze on PTZ - Select All movements to freeze the image while the camera is moving during a pan, tilt or zoom operation.
Once the camera reaches its new position, the view from that position is shown. Presets freezes the image only when the camera
moves between preset positions.
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.

About overlays

Overlays are superimposed over the video stream. They are used to provide extra information during recordings, such as a timestamp,
or during product installation and configuration.
About overlay text
An overlay text can include the current date and time, or a text string. When using a text string, so-called modifiers can be used to
display, for example, the name of the current week or month.
You can choose between the following text overlay sizes:
Size
Small
Medium
Large
It is also possible to display text when an action rule is triggered, see How to include overlay text in an action rule on page 22.
