## How to choose

### 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.

### 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.
