AXIS P3367–VE Fixed Dome Network Camera

Video and Audio

• 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. For example, to get 30 fps, set Max s hutter to 1/30.

• Fixed to use a ﬁxed shutter speed.

Gain, measured in decibel (dB), is the amount of ampliﬁcation applied t o t he 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, re c ognize faces or license plates, m ove 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 ca n 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 ga in. This will red uce image noise and produce smaller im age ﬁ les.

Iris adjustment

Select Enable automatic iris adjustment to a u tomatically 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 a s much as possible. If set to 100, the iris is closed a s much as possible. The actual F-value is shown b elow the

slider. If automatic iris ad justment is enabled, the iris will stay at this pos

ition as long as light conditions are favorable. If light

conditions change, the iris will ad just itself to the bes t iris setting s. 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 nig ht, or

when using an 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 a utomatic Exposure control,settheIRcutﬁlter to Auto to automatically switch between On and Off accordingtothe

lighting conditions.

If using IR illuminations, select Enable focus adjustment for IR illumination.

View Areas

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.

To enable view areas, go to Video & Audio > Camera Settings and select Enable View Areas.

When setting up a view area it is recommended that the video stream resolution is the same size as o r s maller than the view area

size. S etting the video stream resolution larger than the view area size implies digitally s c aled up video after sensor capture,

requiring more bandwidth without adding image information.

To add a new view area:

1. Go to Video & Audio > View Areas.
