SKU · AAD-CAM-UTIM-A · 640 VOx core · CVBS · USB-C
An uncooled LWIR thermal camera with two output modes on one connector: digital UVC for a host application — plug-and-play, no driver needed — or analog CVBS for a video transmitter. 640×480 VOx core, 30 ms latency.
Key Advantage
A high-sensitivity 12 µm VOx core (NETD < 25 mK) with two output modes on one USB-C connector — digital UVC for a host app or analog CVBS for a video transmitter, your integration, your choice. Clean thermal frames at 30 ms latency.

Sees Through the Dark
Detection in total darkness, smoke, fog and degraded visibility — day or night, no illumination required.
Digital or Analog — Your Call
One USB-C connector: digital UVC for a host application (plug-and-play, no driver) or analog CVBS for a video transmitter. Configure once at setup.
Interchangeable Optics
9 mm wide or 19 mm long-range Germanium lenses, matched to the mission profile.
Interchangeable Thermal Optics
Two field-swappable Germanium lenses on the same 640×480 core. Field of view is the trade-off — a wider lens keeps more of the scene in frame, a longer lens magnifies distant heat signatures so the model detects and identifies them sooner.
9 mm Lens
- Focal length9 mm
- ApertureF/1.2
- FOV (H × V)46° × 35°
- FocusFixed ∞
- MaterialGermanium (Ge)
The all-round default — a wide field of view for compact, agile FPV platforms, keeping the target in frame through aggressive terminal maneuvers.
19 mm Lens
- Focal length19 mm
- ApertureF/1.0
- FOV (H × V)22.9° × 17.2°
- FocusFixed ∞
- MaterialGermanium (Ge)
Long-range observation and stand-off detection — the tighter field magnifies distant heat signatures for earlier detection and identification.
Need a different field of view? We supply custom Germanium optics from 9 to 50 mm (9 / 19 / 25 / 35 / 50 mm) — matched to your mission.
Edge-to-Edge Optics
A heat signature the AI can't resolve is a target it can't engage — so we don't cut corners on the glass.
Most low-cost thermal lenses are only sharp in the center of the frame. Toward the edges the thermal image softens, and detection models start to miss or misclassify heat signatures that drift away from the middle of the picture.
Every signature locked — corners and center.
UTIM-A640 uses a high-quality Germanium lens that holds a uniform, sharp thermal image across the entire frame. Targets are detected and identified just as reliably at the edges as they are dead-center — which matters most in the seconds before a target leaves the field of view.
Edges soften — targets missed at the corners.

Tuned for Our Models
UTIM-A640's digital UVC output feeds an onboard detection model directly — Wield-AI runs detection and identification on the live thermal video, drawing a box and a confidence score around every heat signature the model recognises.
Test Dataset on Request
We can provide a representative thermal dataset — and a fully trained model — so you can validate detection and identification before you commit.
In-House Tuning, NUC & Palettes
We set the thermal tonemapping, NUC and palette ourselves, calibrated to the conditions our models are trained on — not a generic factory profile.
Camera & Model, Matched
Because we build both, sensor output and model expectations line up — stronger detection and fewer missed targets out of the box.
