Best Thermal Camera Attachments for iPhone (2026)
As an Amazon Associate we earn from qualifying purchases.
Quick answer: A thermal camera attachment plugs into your iPhone to reveal heat — find drafts, water leaks, electrical hot spots, overheating components, and even pests or radiant-floor lines. Get a consumer thermal cam for home use, a higher-resolution model for pros, or a budget unit to try it. Resolution and temperature range are what separate them.

Pro tip — resolution (thermal pixels) matters more than the marketing megapixels.
Thermal cameras have low native resolution (e.g., 256x192 is good for consumer use); some blend it with your iPhone's camera for a sharper-looking image. For finding drafts and leaks, modest resolution is fine; for pinpointing a single hot connection from a distance, pay for higher thermal resolution.
