1. A system comprising:
an edge device comprising:
computer-readable media storing:
a local signature database service containing a vehicle signature of each vehicle of a census of whitelisted vehicles; and
a first set of instructions;
a Local Processing Unit (LPU) communicatively coupled to a plurality of cameras, wherein the LPU executes the first set of instructions to:
receive a front camera feed and a rear camera feed of a vehicle at a gateway for a restricted access area;
determine a vehicle signature based on a set of visual features of the vehicle; and
perform a license plate read (LPR) on the front camera feed and the rear camera feed, wherein
if the license plate reader reads a license plate correctly, the LPU executes the first set of instructions to:
add the vehicle signature to the local signature database service if the vehicle is entering the gateway;
clear the vehicle signature from the local signature database service if the vehicle is exiting the gateway; and
communicate with a centralized server to synchronize the local signature database service with a centralized signature database service wherein the centralized signature database service stores a plurality of vehicle signatures from a plurality of sites, wherein the LPU transmits event information including one or more images from the front camera feed and the rear camera feed, the LPR and a timestamp; and
if the license plate reader does not read a license plate correctly, the LPU executes the first set of instructions to communicate, to the centralized server, the one or more images from the front camera feed and the rear camera feed and an indication of a mismatch, wherein the centralized server comprises a Cloud Processing Unit (CdPU) configured to execute a second set of instructions to identify the vehicle based on a vehicle signature stored in the centralized database.
