SPECTRA L12E 1280×1024 Uncooled LWIR Network Module with 50 mm F1.0 Lens
Long-wave IR (LWIR): 8–14 μm
SPECTRA L12E is a 1280×1024/12 μm uncooled LWIR network thermal imaging module with a 50 mm F1.0 athermalized fixed lens and 17.5°×14.0° FOV, delivering RTSP video over Gigabit Ethernet and RS485 Modbus RTU for long-range surveillance, perimeter protection and fire detection.
SPECTRA L12E is a high-resolution telephoto network thermal imaging module built around a 1280×1024/12 μm uncooled VOx detector and a 50 mm F1.0 athermalized fixed lens with a nominal 17.5°×14.0° field of view. The module provides one RTSP network video stream over adaptive 10/100/1000M Ethernet with H.264/H.265/MJPEG encoding and ONVIF / GB/T 28181 support, while an RS485 port running Modbus RTU connects directly to industrial control systems. With NETD ≤30 mK, −40 ~ +70 °C operation and typical power consumption below 4 W, it is designed for long-range surveillance, perimeter protection, fire detection and target observation.
