What to look for
Good to know
What is the difference between thermal resolution and visible resolution?
Thermal resolution refers to the number of pixels in the thermal sensor, like 160 x 120. Higher thermal resolution provides more detail in temperature differences. Visible resolution is for the regular camera used for reference images.
Can a thermal camera see through walls?
No, thermal cameras detect surface temperatures, not what is behind walls. They can reveal temperature differences on the surface that may indicate insulation gaps, moisture, or electrical issues.
How accurate are rechargeable thermal cameras?
Most consumer thermal cameras have an accuracy of plus or minus 2 degrees Celsius or 2 percent of the reading. Higher-end models may offer better accuracy. Always calibrate the camera to the ambient temperature for best results.
What is the best thermal resolution for home use?
For most home inspections, a resolution of 160 x 120 is sufficient to detect moisture and insulation issues. If you need more detail, consider 256 x 192 or higher, but they are more expensive.
Do thermal cameras work in the dark?
Yes, thermal cameras do not need visible light. They detect infrared radiation emitted by objects, so they work in complete darkness.
Can I use a thermal camera to detect electrical faults?
Yes, thermal cameras are commonly used to identify overloaded circuits, loose connections, and overheating components. Look for hot spots on breakers, wires, and motors.
How long does it take to charge a rechargeable thermal camera?
Charging times vary. Many models take 2 to 4 hours for a full charge. Some support quick charging, which can reach 80 percent in about an hour.
Are smartphone thermal cameras as good as standalone models?
Smartphone thermal cameras are more portable and often cheaper, but they rely on your phone’s battery and processing power. Standalone models have dedicated screens and longer battery life, making them more suitable for professional use.
Our pick
For most users, the FLIR One Edge Pro offers the best blend of portability, image quality, and ease of use. If you prefer a standalone device and have a tighter budget, the HTI HT-18 is a reliable choice. Professionals who need high-resolution imaging should invest in the FLIR C5 or UNI-T UTi260B.
