Thermal or visible?
Thermal modules image heat and work without visible light. Visible cameras show colour and fine scene detail but need some light, even at a low lux rating.

How to choose
Pick the resolution
At the same field of view, 640 × 512 shows more detail than 384 × 288 or 256 × 192. Match resolution to the target size and working distance rather than choosing the highest by default.
Check the connection
Most modules here output analog CVBS video. MINI 640-2 (USB 2.0) and MINI 640-2 Radiometric (USB Type-C) work on a Windows PC as soon as they are plugged in. Confirm what your host, recorder or transmitter accepts, and the supply voltage.
Evaluate a sample
Order an evaluation sample of the exact configuration, lens and cable you plan to buy, and record what was tested before placing a volume order.
Which TORSUN thermal module has the highest resolution?
MINI 640-2, MINI 640-2 Radiometric and the 640 version of the FPV thermal camera are listed at 640 × 512 with 12 μm VOx detectors. MINI 640-2 lists a 60 Hz frame rate with CVBS and USB 2.0 output; MINI 640-2 Radiometric adds calibrated temperature data over USB, MIPI or DVP; the FPV 640 version lists 50 FPS with PAL CVBS output.
Which TORSUN thermal module can measure temperature?
MINI 640-2 Radiometric. It lists two measurement ranges, −20°C to 150°C and 100°C to 650°C, with typical accuracy of ±2°C or ±2%, and sends temperature data over USB, MIPI or DVP. Radiometric 256 × 192 and 384 × 288 versions are also in stock; ask us for them. The other modules on this page are observation modules and do not list calibrated temperature output.
Which thermal module is the smallest?
The FPV thermal camera lists a 20 × 20 mm body excluding the lens. The MINI-series modules list a 21 × 21 mm footprint; MINI 640-2 lists 21 × 21 × 10.3 mm and 9 g for the core without lens. Confirm the complete assembly with the lens you choose.
Does TORSUN manufacture these modules?
No. TORSUN TECH is a trading company in Dongguan, China. The modules are made by partner manufacturers in China; we coordinate configuration, samples and order follow-up between you and the factory.
How do I get a sample of a thermal or visible module?
Send the model, preferred lens, video connection, quantity and destination through the contact form, by email to info@torsuntech.com or on WhatsApp. There is no minimum order: one unit is fine. We confirm the sample configuration, included items and price with the supplier before you pay.
