AXIS P5635–E PTZ Dome Network Camera
Video and Audio
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. For particular requirements, select a predefined area.
Shutter & Gain
The shutter and gain settings affect the amount of motion blur and noise in the image. To adapt to different lighting, available
storage space and bandwidth, it is often necessary to prioritize either low motion blur or low noise. The Axis product allows
using different prioritization in normal light and in low light.
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 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.
For example, to get 30 fps, set Max shutter to 1/30.
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.

Image Settings

Stabilizer - When monitoring environments that are subject to vibrations (e.g. traffic control), images may appear to be unsteady.
Select On or Off to enable/disable the stabilizer. Enabling the stabilizer will steady the image and will limit the digital zoom.
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.
