For each SharpZ3 camera, you can configure a region of interest which restricts plate detection to a specific part of the field of view.

What you should know

You can use this feature to restrict plate reads to one lane of traffic. For example, if a SharpZ3 is installed on a bus, this feature gives the system the ability to monitor bus lane violations while ignoring other lanes of traffic.
IMPORTANT: The character height filter, plate tilt filter, and the region of interest work in conjunction to filter plate reads. Consider their combined effect when configuring and troubleshooting the system.

Procedure

  1. Log on to the Sharp Portal.
  2. From the Configuration menu, click Cameras > Region.
  3. From the Camera unit menu, select a camera to configure.
    The ALPR video feed is displayed.
  4. Click at least 3 points in the video feed to create a polygon. The camera will only detect license plates within the polygon.
    NOTE: If you are not satisfied with the region of interest, click Clear the region of interest and start again.
    Using the bus lane scenario as an example, the following region of interest would only detect vehicles in the bus lane.
  5. Click Save.

After you finish

Repeat these steps as required for other cameras in the Camera unit menu.
