Thermal Resolution Should Match the Detection Problem
Thermal resolution should be selected by the real detection task, not by specification ranking alone. A 256×192 module may be enough for compact temperature awareness or simple hot-spot detection. A 384×288 module can be a balanced choice for many industrial monitoring and predictive maintenance systems. A 640×512 module is more suitable when the target is smaller, farther away, or requires more thermal detail. A 1280×1024 thermal module should be considered for high-end industrial, research, long-distance or mission-critical thermal imaging projects where budget, processing capability and optical design can support the higher resolution.
For OEM projects, the right question is: what temperature difference must be detected, from what distance, at what field of view, and by which host system?

USB2.0, USB-C or CVBS: Choose by Host Architecture
The interface should be selected according to the customer’s host system and deployment environment.
USB2.0 thermal modules are useful for embedded Linux, Windows, industrial IPCs, inspection devices and cost-sensitive OEM systems that need a practical thermal video input. USB-C is more suitable for modern edge AI devices, compact hardware platforms, higher-resolution modules and applications where mechanical connector design is important. CVBS thermal output is still useful for legacy analog monitors, DVR systems, industrial retrofits and simple field display devices.
If the final system uses Jetson, RK3588, industrial IPC, embedded Linux, Windows software, analog DVR or direct display output, the interface decision should be made before sample selection.
