Feature: 1. It can image clearly, use a longer distance, and ensure operation safety, under the same shooting distance, it can be observed in more detail. 2. Focus‑free design, same distance, larger field of view, easy scanning of indoor floor heating, small space, efficient investigation. 3. Infrared + visible light dual‑light imaging, dual‑light combination is better adapted to different observation target scenes. 4. Type‑C charging interface, 4 hours full charge, 11 hours battery life, instant use, worry‑free power. 5. It has a wide range of applications, such as observing abnormal temperature points, detecting construction quality, material defects, and precise components.
