Description
The Vivotek TB9331-E (8.8 mm) is a rugged outdoor thermal bullet network camera engineered for reliable perimeter protection and situational awareness in challenging visibility conditions. Featuring an uncooled VOx infrared detector with 720×480 thermal resolution and NETD < 50 mk sensitivity, it provides clear, heat-based imaging even through fog, rain, smoke, or complete darkness.
Equipped with H.265 compression, two-way audio, and VIVOTEK’s Video Content Analysis (VCA), the TB9331-E enhances detection, recognition, and identification capabilities for both people and vehicles. Its 8.8 mm fixed-focal lens delivers a 69.6° horizontal field of view, ideal for wide-area surveillance such as perimeter monitoring, critical infrastructure, and border security.
Designed to perform in the harshest environments, the camera is IP66/IP67 weather-proof, IK10 vandal-resistant, and NEMA 4X-rated, ensuring continuous operation from -50 °C to 60 °C. Integrated Trend Micro IoT Security further strengthens network protection, while support for the ONVIF standard ensures seamless integration into existing systems.
