Description
The Wisenet TNU-4051T is a high-performance VGA thermal positioning camera designed for perimeter protection, industrial facilities, critical infrastructure, and wide-area monitoring. Its uncooled microbolometer thermal sensor delivers clear thermal imaging at up to 640×480 resolution, enabling detection and tracking even in complete darkness, fog, smoke, and challenging weather conditions.
Equipped with a built-in 35mm fixed thermal lens and full 360° endless panning with rapid preset speeds, the TNU-4051T ensures wide coverage and precise positioning. Advanced analytics such as loitering, intrusion, virtual fence, shock detection, temperature change detection, and sound classification enhance situational awareness for security teams.
With rugged IP66/NEMA4X environmental protection, a wide operating temperature range, and 24VAC power support, this TAA-compliant thermal positioning camera is engineered for demanding outdoor deployments.
