HJTI-640 Thermal Imaging Core, 640×512 VOx USB/CVBS/MIPI

Applications

Where this core ships

Built for products that need to see heat, not light — day or night, through smoke and haze. If yours isn't listed, ask us about customization.

🚁

Drones & UAV Payloads

24 g, ≤ 0.8 W and 80 g @ 4 ms shock rating — light enough for small UAV thermal payloads with CVBS or MIPI output.

🎥

Handheld Thermal Devices

USB host software for shutter calibration and NUC, 1–8× zoom and multiple palettes — a drop-in core for monoculars and scopes.

🛡️

Security & Perimeter

900 m detection range with the 9 mm lens — see intruders in total darkness, through smoke and light fog.

🏭

Industrial Inspection

NETD ≤ 35 mK resolves fine temperature differences — electrical hotspots, mechanical friction, building heat loss.

🤖

Embedded Integration

26-pin DVP / MIPI interface with 100 Ω matched pairs, DF52 / DF56C connectors and full SDK for secondary development.

🛠️

Custom Integration

Lens, palette set, firmware and interface are customizable — engineering support from spec to mass production.

Why us

A manufacturer, not a trading company

You're talking to the factory that designs and builds the core — not a reseller. Faster sampling, real customization, transparent pricing and direct engineering support.

In-house production lines

Own SMT, AA (active alignment) and reliability testing. We control yield, lead time and quality end-to-end.

Real ODM customization

Custom lens, FOV, firmware, connector and housing. Engineering team supports your design-in from spec to mass production.

First-tier sensors only

Proven, datasheet-backed image sensors — no grey-market chips.

Fast sampling

Standard samples in ~7 days. Custom builds quoted with realistic timelines.

Quality you can audit

Reliability testing (high/low temp, vibration, drop) on every build. Factory audits and video line tours welcome.

Direct engineering access

Talk to the engineers who designed your module — specs, debug and design-in support without layers.
