Overview

Overview

A compact dual-spectrum monitoring camera purpose-built for confined spaces. The 256×192, 12 μm LWIR channel with a 90°×64.2° wide field of view and 0.1 m minimum imaging distance sees inside electrical cabinets, cable mezzanines and battery racks where conventional cameras cannot focus, while the 2688×1520 visible channel with white-light illumination adds scene detail. PoE or DC 12 V power, IP67 protection and magnetic in-cabinet mounting make deployment inside energized enclosures practical.

Key Features

Key Features

Built for confined spaces

  • 0.1 m minimum imaging distance and a 90°×64.2° wide field of view cover switchgear interiors, cable interlayers and battery racks at close range.
  • Compact 111.2×56×38.9 mm aluminum body at 335 g installs where full-size cameras cannot fit.
  • Magnetic in-cabinet mounting plus wall and ceiling brackets; IP67-rated for harsh industrial environments.

Accurate radiometry

  • Measurement accuracy ±2 °C or ±2% of reading (whichever is greater) across −20~150 °C or 0~550 °C ranges.
  • Up to 10 point, 10 area and 1 line measurement rules with real-time alarm linkage.
  • Supports self-trained custom AI thermometry models imported for non-contact precision measurement of specific targets.

Dual-spectrum fusion

  • Thermal channel fuses visible-image detail for sharper thermal scenes; fusion blend ratio continuously adjustable from 0–100%.
  • 16 palettes including white-hot, black-hot, iron-red and rainbow for fast hotspot identification.
  • White-light supplementary illumination up to 3.5 m keeps the visible channel usable inside dark enclosures.

Network-native integration

  • Single-cable deployment with PoE (802.3af) or DC 12 V; 10/100/1000 M adaptive RJ45 port.
  • RS485 with MODBUS, one alarm input (DC 0–3.3 V) and one relay output for local linkage.
  • ONVIF and SDK with full 256×192 radiometric data output; H.265/H.264 streams, up to 20 concurrent previews.
