We've got several FLIR devices in our guide to the best thermal cameras, but the company has also just extended its range of acoustic cameras with three additional models – the new Si2 family.

Just as a thermal imaging camera lets you see the temperature, an acoustic camera is designed to detect and highlight sounds; this can be especially useful in picking up a gas or compressed air leak in a factory environment, for example. Other issues which generally only have audible signs – gas leaks, problems with bearings, or partial discharges at a sub-station for example – can also be plotted on an optical image by FLIR's cameras.
