Thank you for purchasing SIYI’s product.
ZT30 is a four-sensor hybrid optical pod, zoom camera, thermal imaging camera,
laser rangefinder, and wide-angle camera collaborate efficiently. 640 x 512
resolution thermal imaging sensor, 1200-meter range high accuracy rangefinder,
180X hybrid zoom and 30X optical zoom, 4K 1/2.7-inch Sony CMOS, 2K wide-
angle camera, powerful AI identify tracking based on neural network processing
unit, limitless yaw axis, upgraded quick release structure, abundant gimbal control
interface compatible with both SIYI links and third-party links. High accuracy and
high collaboration control algorithms ensure stable imaging and zooming ability
during flight. HDR and starlight night vision extend the application scenarios to
both day and night. In a word, ZT30 optical pod is a rare and good payload for
multi-rotors, VTOLs, and robotics.
To ensure you a good experience of the product, please read this manual carefully.
If you encounter any issue using the product, please consult the manual or check
