VOX Uncooled FPA Electro - Optical Sensor System With HD CCD And IR Thermal Imager

JHS209-S05-100 Ship-borne Electro-optical Tracking Monitoring System

1.1 Brief Introduction

JHS209-S05-100 ship-borne electro-optical surveillance system is a highly integrated optical-mechanical-electro system equipped with a HD 1080p 30× daylight camera, an uncooled LWIR thermal camera and a 5km laser range finder. The system is slaving to a 2-axis and 2-gimbal stabilized platform. Featured with compact and modular design, it is provided for ships meeting military and civilian requirements such as search, observation, reconnaissance and tracking sea-surface and air targets, widely applied in navy, police, coastal guard and maritime etc.
