Description
The Wisenet TNU-4051T is a high-performance VGA thermal positioning camera designed for long-range detection and accurate monitoring in challenging environments. Using an uncooled microbolometer thermal sensor, it delivers 640×480 resolution, excellent contrast, and dependable performance in complete darkness, fog, smoke, and harsh weather.
Equipped with a built-in 35mm fixed lens, the TNU-4051T provides a focused field of view ideal for perimeter defense, industrial facilities, ports, utilities, and critical infrastructure. Its advanced PTZ mechanism supports a 360° endless pan, -90° to 40° tilt, and rapid preset speeds, enabling wide-area surveillance and precise tracking.
With support for H.265/H.264/MJPEG, WiseStream II smart compression, on-board analytics (motion, tampering, audio detection, virtual line/area, temperature change detection), and edge storage up to 256GB, this camera delivers reliable intelligence and efficient bandwidth usage. Its rugged aluminum housing is rated IP66 and NEMA 4X, built for extreme operating temperatures down to –40°C.
A powerful thermal PTZ solution engineered for professional 24/7 security applications.
