384 vs. 640 Thermal Resolution: Which One Should You Choose?
When choosing a thermal optic, one of the most important specifications to consider is sensor resolution https://www.agmglobalvision.com/blogs/agm-blog/384-vs-640-thermal-resolution . A 384×288 thermal sensor can provide excellent performance for close- and mid-range observation, while a 640×512 sensor captures significantly more detail.
The main advantage of 640 resolution becomes noticeable at longer distances and when using digital zoom. With more pixels available, targets tend to retain their shape and important details are easier to recognize. This can be particularly useful when scanning open terrain or observing smaller objects.
However, 384 resolution remains a practical and cost-effective choice for many users. The final image quality also depends on factors such as lens selection, NETD, field of view, display quality, and image processing.
Ultimately, the best thermal resolution depends on how and where you plan to use the device. For frequent long-range observation, 640 may be worth the additional investment, while 384 can offer an excellent balance between performance and price.
