AXIS Q1700-LE License Plate Camera

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
•

Zoom
Privacy masks
A privacy mask is a user-defined area that covers a part of the monitored area. In the video stream, privacy masks appear either as
blocks of solid color or with a mosaic pattern.
The privacy mask is relative to the pan, tilt, and zoom coordinates, so regardless of where you point the camera, the privacy
mask covers the same place or object.
You’ll see the privacy mask on all snapshots, recorded video, and live streams.
You can use the VAPIX® application programming interface (API) to turn off the privacy masks.
Important
If you use multiple privacy masks it may affect the product’s performance.
