SKU · AAD-CAM-UTIM-D · 640 VOx core · Digital Ethernet
An uncooled LWIR thermal camera with digital Ethernet output. The UTIM-D640 delivers H.264 or H.265 video over UDP/RTSP at under 50 ms latency — clean thermal frames in any light, smoke, or adverse weather.
Key Advantage
A high-sensitivity 12 µm VOx core (NETD < 25 mK) delivering H.264 or H.265 over Ethernet — UDP/RTSP, under 50 ms, full HTTP REST API. A standard digital camera that integrates cleanly into any system that speaks RTSP.

Sees Through the Dark
Detection in total darkness, smoke, fog and degraded visibility — day or night, no illumination required.
Live Parameter Control
Video and image parameters — NUC, palette, brightness, contrast — tunable via the built-in web UI, applied live in flight without a reboot.
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 — broad situational awareness for mid-range strike, FPV and ISR, 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-D640 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-D640 isn't a thermal camera that happens to feed an AI — it's built for ours. 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.

Frequently Asked Questions
What thermal core does the UTIM-D640 use?
A 12 µm uncooled VOx core at 640×480 resolution with NETD under 25 mK, for clean thermal contrast in total darkness, smoke, fog and degraded visibility.
What interfaces does the UTIM-D640 support?
One native digital interface — Gigabit Ethernet, streaming H.264 or H.265 over UDP / RTSP at under 50 ms latency, with a full HTTP REST API. The USB-C output — digital UVC for a host application or analog CVBS for a video transmitter — is a separate model, the UTIM-A640.
Can the UTIM-D640's lens be swapped?
Yes — it takes interchangeable 9 mm (wide, 46°×35°) or 19 mm (narrow, 22.9°×17.2°) Germanium lenses on the same 640×480 core.
Is the UTIM-D640 NDAA-compliant and made in the USA?
Yes — the UTIM-D640 is NDAA-compliant and made in the USA.
