You can configure the SharpV to send ALPR data to an HTTP server instead of to Security Center. ALPR data that is sent to an HTTP server can then be integrated by third-party applications.
You can only configure one extension for the SharpV camera.
What you should know
- Log on to the Sharp Portal.
- From the Configuration menu, select the page.
- From the Active extension section, select HTTP from the Extension type drop-down menu.
Configure the following:
NOTE: Information on context images is not applicable to SharpV ITS cameras.
- Enter the URL of the server that receives the ALPR data. For example, https://address:port/path/. Both http:// and https:// are supported.
- Select the format you want to send the ALPR data in. You can select either JSON or XML format.
- Enter the username for the HTTP server (basic authentication).
- Enter the password for the HTTP server (basic authentication).
- Export context images
- Export the context image (in JPEG format).
- Export ALPR images
- Export the plate image (in JPEG format).
- Retain data when the connection is lost
- If the check box is selected, plate reads are saved locally in the SharpV’s
database if the connection with the HTTP server is lost. The SharpV can store up to 20 000 plate read events,
however, note that event size varies based on the complexity of the scene being
observed. The system tries to re-connect with the server every 30 seconds. Stored
reads are pushed to the server when the connection is re-established. If the check
box is cleared, the SharpV does not store
reads locally if the connection with the HTTP server is lost. You can see how many
reads are stored on the SharpV in the
Dashboard > Overview > Storage and usage section.
NOTE: If there are any plate reads in the SharpV's database, clearing this check box and saving the configuration deletes the plate reads.
- Anonymize ALPR data
- The camera hashes the license plate
using the SHA-1 algorithm. When you add an alphanumeric salt (cryptography)
to the license plate number, it increases the security of the hashed output. Adding
the same salt on all of the cameras in a network means that the same license plate
produces an identical hash on all cameras. This allows the external system to
recognize the identical hashes as a the same vehicle while still maintaining privacy.
IMPORTANT: If the salt is changed after it is set, it must also be changed on all other cameras. Changing the salt breaks the link between old reads and new reads.
- Ignore certificate errors
- Select this option when sending ALPR data to an HTTPS server that does not have a trusted certificate. The SharpV will not send the ALPR data to an HTTPS server that does not have a trusted certificate unless you select this option.
- Click Send sample to send a test plate to verify that the system can connect to the server using these settings.
- Click Save.
