cameras.
Videos
- Camera unit
- The SharpV camera unit ALPR camera unit 1 is displayed.
- Cameras
- You can select which camera feeds (ALPR or context) to view. The No camera option is useful when you want to conserve CPU usage and network bandwidth while monitoring reads.
- Overlays
-
- Crosshairs: Select this option to display crosshairs in the ALPR or context camera window.
- Bounding box: Select this option to display the yellow bounding box around detected plates in the ALPR camera window.
- Region of interest: A region of interest limits plate detection to a specific part of the field of view. This can be used to ensure that the system focuses on the best region to capture plates or to exclude plates passing in certain regions.
- Record
- Click the Record button to capture a series of context and ALPR
images directly from the Camera feeds window and save them to your
computer as a .zip file for debugging purposes. NOTE:
- Using the Record feature increases CPU usage.
- To use this feature, you cannot use the camera's auto-generated certificate. You must install a self-signed certificate that includes the IP address of the camera.

camera can read up to 30 frames (reads) per second. The Read
strategy configured on the Analytics page
determines which read candidate will be used as the final read.NOTE:
- The list contains the reads that have been made in this portal session. Exiting the session resets the list.
- The list is of limited length and older reads are automatically removed.
- Clicking on an entry pauses the list. Clicking Play resumes the list refresh and adds new reads that were received while the list was paused.
