FAQ

Q: What is the iVA-A640LW/LWT thermal camera module used for?
A: The iVA-A640LW/LWT is designed for UAV thermal imaging, embedded vision systems, industrial monitoring, security surveillance, and AI-powered thermal inspection applications.

Q: What resolution and frame rate does the module support?
A: It delivers 640×512 thermal imaging resolution with up to 60Hz frame rate for smooth real-time thermal video.

Q: What is the spectral range of the camera?
A: The module operates in the 8–14μm long-wave infrared (LWIR) spectrum, enabling reliable thermal detection in low-light and challenging environments.

Q: How sensitive is the thermal detector?
A: The camera features a typical NETD of ≤ 40mK, allowing it to detect very small temperature differences with high accuracy.

Q: Is the iVA-A640LW/LWT suitable for UAV integration?
A: Yes. With ultra-low power consumption of only 1W and a compact core module design, it is ideal for drones and battery-powered platforms.

Q: What video output interfaces are available?
A: The module supports CVBS, USB (UVC), and BT.656 outputs for easy integration into embedded vision and thermal imaging systems.

Q: Does the camera support temperature measurement?
A: Yes. It provides stable and accurate temperature measurement for industrial monitoring, fire detection, and thermal inspection applications.

Q: What are the key advantages of the iVA-A640LW/LWT?
A: It combines 640×512 resolution, 60Hz imaging, NETD ≤ 40mK sensitivity, ultra-low 1W power consumption, and multiple output interfaces in a compact thermal camera module.

Product Description

The iVaster iVA-A640LW &iVA-A640LWT is a self-developed uncooled LWIR thermal core with 640×512 resolution and 12μm pixel pitch, covering the standard atmospheric window spectral band of 8–14μm. Built-in proprietary LightPath image algorithms deliver crisp edge definition, rich scene details and smooth frame output, paired with reliable temperature measurement performance.


Separated into observation-only and full radiometric temperature measurement versions, this module covers a wide spectrum of applications: perimeter security monitoring, UAV aerial inspection, law enforcement rescue, industrial thermal inspection and wildlife observation. Thanks to standardized modular design, abundant stock and factory-direct low pricing, it becomes the top OEM thermal core choice for integrators pursuing low cost and short delivery cycles.

 

Core Competitive Advantages

Our iVaster series distinguishes itself from other LWIR camera lines with two core strengths: competitive factory-direct pricing and ultra-short lead times for mass orders, plus outstanding compact thermal performance.
  1. Low Cost for Mass Production Integration

    Equipped with self-developed LightPath image processing algorithms and standardized modular structure without redundant hardware design. Compared with mainstream 640×512 thermal cores in the market, it delivers obvious cost advantages for system integrators. Tiered volume pricing is available to cut down BOM costs of thermal cameras, UAV payloads, handheld thermometers and rescue devices for bulk OEM customers.
  2. In Stock & Ultra-Fast Delivery

    Standard models with regular lenses and standard interfaces are kept in permanent inventory. Standard orders ship within 7-14 working days. Custom lens or interface modifications can be scheduled rapidly, drastically shortening the typical industry lead time of 4–8 weeks. Ideal for rush projects and mass batch shipments.
  3. Ultra-Compact, Lightweight & Low Power SWaP Design

    Mini dimension only 26×26×21.1mm with weight under 23g; ultra-low power consumption ≤1W, powered by wide DC 5–12V input. Perfect for battery-powered mini devices including drone payloads, portable observation units, vehicle-mounted night vision and embedded small equipment with limited installation space.
  4. Dual Versions: Observation & Radiometric Temperature Measurement

    Two variants to match different project demands:
  • iVA-A640LW: 50Hz high frame rate for pure visual observation without temperature output
  • iVA-A640LWT: 30Hz radiometric core with full temperature measurement function

    Both feature excellent thermal sensitivity NETD ≤40mK and stable temperature accuracy for clear detail recognition day and night.
  1. Full-Range Interfaces for Easy Secondary Development

    Multiple video outputs and control ports compatible with industrial motherboards, FPGA and display devices. Complete Windows/Linux/Android SDK packages are provided free for fast integration without complicated adaptation work.
  2. Industrial-Grade Environmental Reliability

    Wide operating temperature range from -20°C to +60°C. Passed strict vibration and shock tests to sustain harsh outdoor, airborne and vehicle-mounted working conditions, lowering long-term maintenance and after-sales costs.
