Underwater HD Live Video Stream
 |
Product Introduction
360° No Dead Angle, Underwater Panoramic Monitoring, Low-Light Compensation ● Dual Pan-Tilt (Horizontal + Vertical), 360° coverage, switchable between auto-patrol and remote control ● Adjustable angle fill lights for full-view low-light illumination ● SDK available for secondary development in C++, Java, C#, Python, etc. |
Application Scenarios:
● Panoramic view with a single camera
● Continuous rotation and monitoring
● Fixed-point monitoring where stability is prioritized over “smart” features
