AXIS Q1942-E Thermal Network Camera
Video and Audio
Lowest Zipstream strength is the default setting for the product. This configuration is very safe to use in all applications while still
reducing the bit rate.
For cloud-connected cameras or cameras using edge storage that need to limit the bit rate for increased storage time it is
recommended to select the Highest Zipstream strength. This setting is very good to combine with motion detection triggering and
variable bit rate (VBR) where the bit rate is allowed to adapt to changes in complexity in the scene.
Axis' Zipstream Technology for H.264 conforms to the H.264 standard and is compatible with third-party clients and VMS solutions
that decode H.264 video.
The bit rate controller built into the product can be combined with Zipstream to enforce a maximum bit rate (MBR) limit. Axis
Communications recommends using VBR or MBR with a rather high bit rate limit to enable the full potential of Axis' Zipstream
Technology.

Sometimes the image size is large due to low dynamic or complex scenery. Adjusting the maximum frame size helps to control the
bandwidth and storage used by the Motion JPEG video stream in these situations. Setting the frame size to the Default setting
provides consistently good image quality at the expense of increased bandwidth and storage usage in low dynamic. Limiting the
frame size optimizes bandwidth and storage usage, but may give poor image quality. To prevent increased bandwidth and storage
usage, the maximum frame size should be set to an optimal value.

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 Events on page 35.
• When setting up continuous recording. See Continuous Recording on page 41.
• In the Live View page – select the stream profile from the Stream profile drop-down list.
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 & Audio > Stream Profiles.
To select a default stream profile for the Live View page, go to Setup > Live View Config.

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
can be set through the ONVIF Media Profile Settings page and be used by a client to configure media stream properties.
The ONVIF Media Profiles page lists all such pre-configured profiles. These profiles cannot be removed. Pre-configured media
profiles have been included in the product for quick setup. It is also possible to configure new ONVIF media profiles as per required
specifications. To add a new ONVIF media profile, click Add and enter the required information. You can also modify or remove a
profile from this page.

Camera Settings

The Video & Audio > Camera Settings page provides access to advanced image settings for the Axis product.
Image Appearance
To change Image Appearance go to the menus under Setup > Video & Audio > Camera Settings.
The image Brightness can be adjusted in the range 0–100, where a higher value produces a brighter image.
