SIYI ZT30-D Four-Sensor Optical Pod Gimbal Camera

A single-sensor gimbal camera forces a choice between visual, thermal, or zoom detail on any given pass, while a four-sensor optical pod like the ZT30-D captures multiple data types simultaneously - genuinely useful for inspection or survey missions that need visual context alongside thermal or zoomed detail without flying the route multiple times with different payloads. This D-variant sits in SIYI's top-tier optical pod line, built for the kind of professional survey and inspection work where payload capability matters more than unit cost.
