Native HDMI Output — The Simplest Path to Thermal Display

HDMI (High-Definition Multimedia Interface) is the universal digital video standard present on virtually every modern monitor, TV, projector, capture card, and display processor. The HDMI thermal module outputs a standard HDMI digital video signal that any HDMI-equipped display device receives and shows immediately — no driver installation, no network configuration, no USB host software, no IP address, no additional hardware beyond the HDMI cable. This zero-configuration direct display capability is the HDMI module’s primary advantage over the Ethernet module (requires network infrastructure), the USB module (requires USB host software), and the CVBS module (requires analog display or frame grabber). For applications where the thermal image is primarily consumed by a human operator viewing an HDMI monitor — a control room display, an inspection workstation monitor, a field tablet with HDMI input, or a video wall — the HDMI module provides the simplest and most direct integration path.

<30 mK NETD — The Highest Sensitivity in the Standard Range

The <30 mK NETD specification places this module in the highest sensitivity tier of the standard LWIR OEM module range, alongside the USB module’s top sensitivity option. At <30 mK, the module detects temperature differences as small as 0.03°C — enabling reliable detection of very early-stage electrical equipment faults (nascent connection resistance that raises temperature by only 1–2°C above ambient), subtle building insulation deficiencies (small temperature differences through thin insulation gaps), low-contrast thermal scenes (person detection against a background close to body temperature), and fine biological temperature variations. This sensitivity advantage over <50 mK modules is directly meaningful for precision inspection and long-range surveillance applications where small temperature differences must be detected reliably against background noise.

Direct HDMI Output — Zero-Configuration Display Integration

Native HDMI connectivity connects directly to standard displays and HDMI capture cards without additional converters, significantly reducing system complexity and integration time. Any HDMI-equipped monitor, TV, projector, or capture card receives the full-quality thermal video immediately on connection — the simplest thermal imaging display integration available in the module range.

Exceptional <30 mK Thermal Sensitivity

With NETD below 30 mK, the module detects temperature variations below 0.03°C — the highest sensitivity in the standard LWIR OEM module range. This enables precision diagnostics in electrical inspection (detecting 1–2°C connection resistance faults), long-range surveillance (detecting human body heat against near-ambient backgrounds), and fine structural thermal analysis (identifying narrow insulation gaps from their small temperature differential).

640×480 px High-Definition Thermal Resolution

The 640 × 480 px LWIR detector delivers sharp thermal imagery enabling accurate identification of temperature gradients, hotspots, and heat leaks. The VGA-format resolution provides sufficient spatial detail for human and vehicle detection, component-level industrial inspection, and building envelope thermal assessment at standard monitoring and inspection distances.

Advanced On-Board Image Processing

Built-in automatic and manual gain control, temporal and spatial filtering, and multiple colour palettes ensure high-contrast, low-noise thermal images in dynamic environments. The on-board processing delivers display-ready video over HDMI with no image processing requirement at the connected monitor or capture device.

Compact ~40×38×43 mm with Interchangeable Lenses

Small form factor and light weight suit space-constrained installations, UAV payloads, handheld instruments, and mobile systems. Interchangeable lenses provide field-of-view flexibility for different application geometries — wide-angle for close-range area monitoring, telephoto for long-range target detection — without replacing the module.

Fast <5 Second Startup and 9/30/60 Hz Frame Rates

Sub-5-second startup provides immediate thermal visibility for on-demand and mission-critical applications. Selectable 9/30/60 Hz frame rates cover regulatory-compliant export (9 Hz), smooth real-time monitoring (30 Hz), and high temporal resolution (60 Hz) requirements.
