AXIS P3353 Network Camera
Setting Up the Product
•
Fixed
to use a fixed shutter speed.
Gain
, measured in decibel (dB), is the amount of amplification applied to the image. A high gain may provide a better image in low
light situations but will increase the amount of image noise.
Set
Gain
to
•
Auto
to set the gain automatically. If required, use
Max gain
to limit the applied gain.
•
Fixed
to use a fixed gain.
When
Shutter
and
Gain
are both set to
Auto
, it is possible to set the
Priority
between low motion blur and low noise manually and to
use a different
Priority
in
Normal Light
and in
Low Light
.
Example
Consider an area where people or vehicles move during the day, but where there should be no movements during night. To be able to,
for example, recognize faces or license plates, move the normal light priority slider toward low motion blur. At nighttime, motion
detection is more important than identification. Motion blur is acceptable and since low light can cause a lot of noise, move
the low light priority slider toward low noise.
Example
If storage space or bandwidth is limited, try using a lower gain. This will reduce image noise and produce smaller image files.
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.
Use the
Iris adjustment
slider to set the preferred F-value. The scale represents the amount the iris is open. If set to 0, the iris
is opened as much as possible. If set to 100, the iris is closed as much as possible. The actual F-value is shown below the
slider. If automatic iris adjustment is enabled, the iris will stay at this position as long as light conditions are favorable. If light
conditions change, the iris will adjust itself to the best iris settings. If automatic iris adjustment is disabled, the iris will lock on
the set position regardless of light conditions
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. The 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 Area
.
To configure the view area:
