About stream profiles
A stream profile is a set of predefined stream settings including resolution, compression, frame rate and overlay settings. Stream
profiles can be used:
•
When setting up recording using action rules. See
•
When setting up continuous recording. See
About continuous recording on page 40
•
In the Live View page – select the stream profile from the
Stream profile
drop-down list.
To create a new profile or modify an existing profile, go to
Setup > Video

About ONVIF media profiles
An ONVIF media profile consists of a set of configurations that can be used to change media stream settings. ONVIF media profiles

The
ONVIF Media Profiles
page lists all preconfigured profiles. These profiles are included in the product for quick setup. You can
add, modify or remove ONVIF media profiles from this page.

Increasing the
Sharpness
can increase bandwidth usage. A sharper image might increase image noise especially in low dynamic
conditions. A lower setting reduces image noise, but the whole image will appear less sharp.
About exposure settings
Configure the exposure settings to suit the image quality requirements in relation to temperature variations in the scene.
Automatic gain control -
This setting is used to automatically adjust the gain to an appropriate range, the weaker the image signal,
the stronger the gain. Select the
Linear
or
Equalization
automatic gain control method. The latter uses a histogram equalization
method, which adjusts the gain dynamically by distributing the most frequent intensity values.
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
Defined
and then click
Edit
and select one of the predefined areas.
Gain -
Gain is the amount of amplification applied to an image signal. More gain means more contrast and more details but also
more noise. The max gain value is set for all scenes, but affects primarily low contrast scenes controlling the amount of allowed noise
in the image, which in turn also limits the contrast.
About overlays
Overlays are superimposed over the video stream. They are used to provide extra information during recordings, such as a timestamp,
or during product installation and configuration.
About overlay text
An overlay text can include the current date and time, or a text string. When using a text string, so-called modifiers can be used to
display, for example, the current bit rate or the current frame rate.
You can choose between the following text overlay sizes:
