[57north-discuss] Infrared thermal imaging cameras for energy saving

Hi I've been looking at thermal imaging cameras lately, to help improve the energy efficiency of our home. It's probably a bit daft living in a large-ish 150 year old house, but that's done already, so, hmm.

Aye, so I've no idea whether it's a good idea, if the cheaper ones are still useful, if it'll save money enough to pay for itself. Anyone have any ideas or experiences? Thanks :) Andy Kits and DIY things... https://shop.pimoroni.com/products/mlx90640-thermal-camera-breakout https://www.raspberrypi.com/news/raspberry-pi-thermal-camera/ USB phone/tab attached ones... https://www.thermal.com/compact-series.html https://www.flir.co.uk/products/flir-one-pro-lt/ https://perfectprime.com/products/ir202 Standalone ones... https://www.toolstation.com/rothenberger-ro-tcam-thermal-imaging-camera/p61… https://hti-instrument.com/collections/new/products/ht-a2-thermal-imager Rental... https://www.hss.com/hire/p/handheld-thermal-camera https://www.test-meter.co.uk/hire/thermal-camera-hire
