Overview

The ST-PTZ4250 pairs a 1/1.8-inch back-illuminated sensor with a 25× optical zoom block, so a single camera covers a whole conveyor gallery or yard without losing licence-plate detail at the far end. Smart-IR adapts its beam angle to the zoom position, and on-board AI classifies people and vehicles at the edge, which matters where uplink bandwidth is scarce.
