EPi Gatekeeper

EPi Gatekeeper automates vehicle access at parking lots and any site where the license plate has to be checked. AI License Plate Recognition runs on the live camera feed and reads the plate, brand, vehicle type and a few other attributes from each car passing the entry or exit barrier; a snapshot of the plate is stored together with the event.

The app keeps a daily history of every vehicle that attempts to pass through. Cars that are not registered for the site can be enrolled on the spot — either as permanent residents or as visitors — and the app drives the barrier open or closed accordingly. Entry / exit durations are computed automatically so total stay time is known, and a live occupancy counter knows whether the lot is full or has free spots. When the lot is full, new vehicles are denied access unless the owner overrides the rule. A connected LED sign mirrors that state to people approaching the gate.

Every camera is supported through the same LPR pipeline. As an alternative to plate recognition, the system also drives RFID readers — tagging vehicles and doing the exact same flow off the tag data. A permissions layer covers user creation with specific rights, and a health tab tracks the live status of cameras, RFID readers and other components.
