AXIS P1214–E Network Camera
Video
For quick setup, use one of the predefined stream profiles. Each predefined profile has a descriptive name, indicating its purpose. If
required, the predefined stream profiles can be modified and new customized stream profiles can be created.
To create a new profile or modify an existing profile, go to Setup > Video > Stream Profiles .
To select a default stream profile for the Live View page, go to Setup > Live View Config .
Camera Settings
The Video > Camera Settings page provides access to advanced image settings for the Axis product.
Image Appearance
Increasing the Color level increases the color saturation. The value 100 gives maximum color saturation. The value 0 gives a
black and white image.
The image
Brightness
can be adjusted in the range 0–100, where a higher value produces a brighter image.
Increasing the Sharpness can increase bandwidth usage. A sharper image might increase image noise especially in low light
conditions. A lower setting reduces image noise, but the whole image will appear less sharp.
The Contrast changes the relative difference between light and dark. It can be adjusted using the slidebar.
White Balance
White balance is used to make colors in the image appear the same regardless of the color temperature of the light source. The Axis
product can be set to automatically identify the light source and compensate for its color. Alternatively, select the type of light
source from the drop-down list. For a description of each available setting, see the online help .
Exposure Settings
Configure the exposure settings to suit the image quality requirements in relation to lighting, frame rate and bandwidth
considerations.
Exposure value - Click in the bar to fine-tune the exposure.
Exposure control - These settings is used to adapt to the amount of light used. Automatic is the default settings can be used in most
situations. The shutter speed is automatically set to produce optimum image quality. Flicker-free 50 or 60 Hz is used to remove
flicker which can be caused by fluorescent and other light sources. The
Hold current
option locks the current exposure settings.
Enable Backlight compensation - Enable this option if a bright spot of light, for example a light bulb, causes other areas in
the image to appear too dark.
Exposure zones - This settings determines which part of the image is used to calculate the exposure. For most situations, the Auto
setting can be used. For particular requirement, select a predefined area.
Exposure priority - When Motion is prioritized and maximum Shutter time is set to a small value, motion blur in the image is
minimized. This can be useful for recognition of moving objects such as people and vehicles. However, prioritizing motion may cause
an increase in image noise, especially in low light situations. When
Low noise is prioritized and Gain is set to a small value, image
noise is minimized. The file size is reduced, which can be useful if storage space or bandwidth is limited. However, prioritizing low
noise may result in a very dark image, especially in low light situations.
Overlay
Overlays are used to provide extra information, for example for forensic video analysis or during product installation and
configuration. Overlays are superimposed over the video stream.
