AXIS M3104-LVE Network Camera
Video
The
Hold current
option locks the current exposure settings.
Max exposure time -
Shutter speed, also called ‘exposure time’ stands for the length of time the camera shutter is open, thereby
exposing the camera sensor to light. If shutter speed is fast it can freeze action effectively. If shutter speed is slow, it can cause
moving objects to appear blurred. Decreasing the exposure time will reduce motion blur.
Exposure zones -
This setting determines which part of the image is used to calculate the exposure. For most situations, the
Auto
setting can be used.
You can select a predefined area by defining Include and Exclude windows within the image. Exclude windows exclude areas that are
too bright or dark, and Include windows include areas in the scene that have better lighting which will contribute to the exposure data.
There must be at least one Include window. There can be a total of ten Include and Exclude windows to tailor the exposure zone.
Note that an Exclude window is effective only when placed inside an include window.
Tip: If an area is extremely bright draw an Include window to cover the whole area and define Exclude windows within it to
block out the bright areas.
Shutter & Gain
Normal Light -
Use the slider to set the
Priority
between
Low motion blur
and
Low noise
. When prioritizing low noise (slider
all the way to the left) the Axis product will automatically decrease shutter speed as brightness decreases. When the shutter
speed reaches 1/30 s the Axis product will increase gain until the set maximum gain for normal light is reached. Select the
Max
gain
value from the drop-down list. This defines the upper limit for gain in the context of normal light.
Max fast shutter
sets
shutter speed limit in normal light conditions. Depending on a scenario, the shutter speed limit may need to be defined. This is
done through
System Options
>
Advanced
>
Plain Config
.
Low Light -
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 will automatically increase 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.
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.
Built-in IR Illuminations LEDs
The IR illumination can be activated or de-activated, and its intensity can be increased or decreased by moving the slider, from
the product’s
Live View
page.
Other settings can be defined from
Setup
>
Video
>
Camera Settings
.
De-select the
Enable IR illumination
option to disable IR illumination altogether. If you disable the
Synchronize IR illumination with
day/night
option, IR illumination will not be synchronized with day/night changes.
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.
