During shift changes or peak entry periods, multiple vehicles approach the gate in close succession. A driver presents valid credentials, and the gate opens. A second vehicle follows closely behind before the gate closes.

AVA verifies each vehicle entering the gate lane. If a second vehicle attempts to pass without authorization, the system detects the tailgating event and immediately triggers audio deterrence while recording the incident for review.

Delivery vehicles frequently arrive throughout the day, often in groups. When one vehicle is granted access, others may follow through the gate without verification.

AVA monitors vehicle movement through the entry lane and verifies each plate against authorized access records. If an additional vehicle attempts to follow without approval, the system detects the violation and initiates deterrence while notifying security personnel.
