Description
The Vivotek TB9331-E (50mm) is a high-performance outdoor thermal bullet network camera engineered for long-range perimeter security and critical infrastructure monitoring. Designed to deliver reliable human and vehicle detection even in complete darkness, smoke, fog, rain, or dust, it uses an uncooled VOx infrared detector and thermal imaging technology to detect targets up to 4.5 km away.
With a 50mm fixed-focal thermal lens, the TB9331-E provides precise long-distance detection, including vehicle detection up to 4,549 m (14,924 ft) and human detection up to 1,490 m (4,888 ft). It supports H.265 compression, reducing bandwidth while maintaining image quality, and features VIVOTEK VCA (Video Content Analysis) for advanced analytics such as line crossing, loitering, and field detection.
Enhanced with Trend Micro IoT Security, two-way audio, and ONVIF compliance for seamless integration, the TB9331-E ensures robust security performance. Its IP66/IP67 weather-proof, IK10 vandal-resistant, and NEMA 4X-rated housing guarantees reliability in the harshest environments, operating from -50°C to 60°C. Ideal for border protection, facility perimeters, and industrial security, this camera delivers unmatched performance and durability.
