AXIS Q1615-E Mk II Network Camera
Video and Audio
Shutter speed is related to the amount of time the shutter is opened and is measured in seconds (s). A slow shutter speed allows
more light to reach the sensor and can help produce a brighter image in low light situations. On the other hand, a slow shutter
speed can cause moving objects to appear blurry.
Set Wide Dynamic Range to WDR Off and set Shutter to
•
Auto to set the shutter speed automatically. If required, use Max shutter to limit the shutter speed to prevent the frame
rate from being reduced.
•
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.
Example
If storage space or bandwidth is limited, try using a lower gain. This will reduce image noise and produce smaller image files.
Iris configuration
Iris configuration shows the current configured iris type. Do not change the iris configuration unless the lens has been changed, see
Replace the Lens on page 11 .
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.
