3.3 Adjusting the field of view visualization

Axis Camera Families feature adjustable field of view visualization. This makes it possible to get an
overview of the camera coverage in floor plans, sections and 3D views.
important
The field of view visualization is provided for guidance. Individual variations of the field of view could
exist between cameras, e.g. due to back focus adjustment and lens distortion. Plan with margins.
3.3.1

Tilt, Pan and Focal Length

The camera tilt and rotation are controlled by the FOV Tilt and FOV Pan properties. For dome cameras,
only the field of view visualization is tilted and rotated. For other cameras the camera housing is also
tilted and rotated.
important
The field of view visualization can be tilted or rotated outside the range supported by the camera or
the environment where the camera is mounted. You must ensure that it is possible to achieve the
desired tilt and rotation in your particular situation.
The focal length is adjusted using the FOV Desired Focal Length property. The field of view visualization
is limited to the focal range supported by the camera. The actual focal range used is shown as FOV
Actual Focal Length. If this value is not the same as the FOV Desired Focal Length, the selected focal
length is outside the camera's range.
3.3.2

Size and visibility of field of view visualization

The extent of the field of view visualization is controlled by the FOV Distance to Object, FOV Upper
Limit and FOV Bottom Limit properties. The field of view visualization will extend horizontally from the
camera to a distance set by FOV Distance to Object. The top of the field of view visualization will be cut
off at a distance from the camera insertion point set by FOV Upper Limit, and the bottom will be cut
off at the distance set by FOV Bottom Limit. To cut the field of view visualization at floor level, set FOV
Bottom Limit to the same value as Offset.
