AXIS M31 Series
Setup
1. Go to
Settings > System
>
Orientation
and click
.
2. In the camera’s live view, adjust the size and placement of the rectangle around the area of interest, for example, where
the faces of passing persons are expected to appear. You can then see the number of pixels represented by the sides of
the rectangle.
Note
You can use an object of a known size in the view as a reference to decide how much resolution is needed for recognition.
Improve license plate recognition
To better recognize the license plate of a car passing by the camera, you can apply and adjust a number of things.
One option is to use the pixel counter in your camera to set the optimal pixel resolution:
1. Go to
Settings > System
>
Orientation
and click
.
2. Adjust the size and placement of the rectangle in the camera’s live view around the area of interest, for example
where the license plates of passing cars are expected to appear. You can then see the number of pixels represented by
the sides of the rectangle.
Note
You can use an object of a known size in the view as a reference to decide how much resolution is needed for recognition.
In addition, you can try to adjust the following to optimize license plate recognition:
•
Shutter speed
•
Gain
•
Zoom
View area
A view area is a cropped part of the full view. You can stream and store view areas instead of the full view to minimize bandwidth
and storage needs. If you enable PTZ for a view area, you can pan, tilt and zoom within it. By using view areas you can remove parts
of the full view, for example, the sky.
