Background Information
To facilitate vehicle management, you can add the plate numbers to the blocklist or allowlist. The
system can compare the detected plate information with the plate on the blocklist and allowlist and
then trigger the corresponding alarm linkage.
● With the blocklist and allowlist enabled, on the live page, the plate on the blocklist is displayed as
red on the plate list and the plate on the allowlist is displayed as green. For the plate not on the
blocklist or allowlist, the color is white.
