Digital Camera World Verdict

The FLIR ONE Edge Pro is a significant improvement on FLIR’s previous phone attachment, with no vulnerable connection points and a longer use time. It’s quite pricey, even compared to FLIR’s own alternatives, but the phone link is convenient and the app is excellent. Dependence on the phone isn’t for every job, but for most, it comes naturally and even offers advantages like extra metadata.

Thermal imaging cameras are moving from the world of deep-pocketed professionals to something within everyone’s reach and – as with so much – a factor is the phone. Thermal imaging can reveal faults in electronics or cars which have yet to be present, they are an essential tool for HVAC engineers, and when checking insulation. They can even identify water damage, or the studs in walls, so DIY fans of all kinds can enjoy them – as well as kids learning about their world.

FLIR is a leading brand in all areas of thermal imaging, and many of their cameras connect to their back-end suite which includes cloud storage (up to 1TB for free) as well as some options aimed at businesses to streamline reporting.
