ViewPro H4T-25/H4T-19 Mini 3-Axis 8K Quad-Sensor Al Gimbal Camera
The ViewPro H4T series represents a breakthrough in miniaturized aerial intelligence. This 3-axis gimbal integrates four high-performance sensors into one compact payload. It features 8K wide-angle and zoom cameras for unmatched visual clarity. Consequently, it provides operators with comprehensive situational awareness for complex missions. The lightweight design makes it compatible with many small UAV platforms. Whether for security or inspection, this gimbal delivers professional-grade results.
Quad-Sensor Capabilities
This advanced system combines four vital modules to maximize operational efficiency. First, the 48MP wide-angle camera captures broad vistas in stunning 8K resolution. Second, the 10x optical zoom camera allows for detailed inspections from a safe distance. Third, the uncooled VOx thermal imager provides clear 640×512 heat signatures. Finally, an integrated laser rangefinder accurately measures target distances up to 1500 meters. These sensors work together to provide a complete data set in real-time.
AI-Powered Tracking
Intelligence is at the core of the H4T series. The gimbal features advanced AI algorithms for automatic target identification. It can detect and lock onto humans and vehicles simultaneously. Furthermore, the tracking system maintains a lock even if the target is briefly obscured. This automation reduces the pilot’s workload during high-stakes search and rescue operations. You can switch between visible and thermal views while maintaining track. This ensures you never lose sight of your objective.
Industrial Applications
The H4T-25 and H4T-19 are built for demanding industrial environments. They excel in power line inspections where high resolution is mandatory. Additionally, the thermal sensor is perfect for identifying hotspots in firefighting missions. The laser rangefinder helps in mapping and disaster management by providing precise coordinates. Because it supports multiple control protocols like S.BUS and UART, integration is seamless. It is truly a versatile tool for modern drone professionals.
