I used a FLIR i7 this week to find a whole section of wall that had no insulation in it. By feel, it felt colder, but damn if the wall was 55f most places but nearly 35f where there was no insulation. It would have taken me hours to run my hand and/or use a laser-based infrared thermometer; found enough places to work on in just 15 minutes with the FLIR cam..

I have a 100 year old house that I've been remodeling, and this would enable me to easily find air leaks. I'm skeptical that it will enable me to find studs through horsehair plaster (they show visible studs in the gallery), but it will certainly make it easier to locate the position of forced hot water pipes in the walls and ceilings.

My Flir E4 camera arrived just yesterday and today I plan to investigate if overheating is the reason for my 3d printer (Ultimaker 2) to be unreliable on large prints. Also, I hope to have an insight which parts are getting hot and estimate the best place for a fan.

I think the use cases outlined on the site are pretty stupid.

Neat implementation, but is there a market?

I think it'd be a fun toy.

IR cameras are useful for doing efficiency evaluations of buildings.

Thank you all for the replies.
