TOPOTEK KHT30C Four-Sensor Drone Gimbal Product Description
Product Overview: The KHT30C is a professional three-axis gimbal that integrates 270x mixed optical zoom, fixed-focus 1080P camera, 640x512 thermal imaging camera with 35mm focal length, and an 1800-meter laser rangefinder. It adopts a compact design and features high stability and integration. It has the characteristics of high accuracy and low power consumption; the visible light camera uses a wide dynamic sensor with 2 mega pixels; the thermal imaging uses a vanadium oxide 640x512 resolution detector with a built-in baffle. This device provides ground station software, supports picture-in-picture display of dual-channel video, network, S.BUS, and UART control, supports local TF storage and network file read and write operations, and supports dual-channel synchronous recording, and multiple picture-in-picture modes and pseudo-color switching.
