The Cameras I Tested
The [FLIR ONE Pro Thermal Camera for Smartphone](https://www.amazon.com/s?k=FLIR+ONE+Pro+Thermal+Camera+for+Smartphone&tag=thetestedhub-20) was my top pick because the MSX overlay made every scan readable at a glance and the resolution was best in the test for a phone attachment.
Check price on Amazon →I scanned my walls, breaker panel, and roof with five thermal imaging cameras to see which units actually catch real heat problems.

The Cameras I Tested

Quick answers
Eighty by sixty pixels finds insulation gaps and missing studs. For pinpoint electrical work, two hundred by one fifty or higher gives much clearer hot-spot detail.
For occasional homeowner use, yes. The phone models I compared matched the standalone unit on a wall scan but the dedicated camera wins on battery and screen brightness.
