FLIR ONE Gen 3 - Thermal Imaging Camera for iOS Smartphones (iPhone 15 and Newer w/USB-C): Use for Home Inspection, HVAC, Automotive, Machine Industries and More
The FLIR ONE Gen 3 is a compact thermal camera designed to plug directly into newer iPhones with USB-C, making it very convenient for quick home inspections, automotive checks, or HVAC work. It delivers thermal images at 80x60 resolution, which is lower than visible camera resolution but typical for entry-level thermal devices in its price range. Its temperature measurement covers 5 °C to 120 °C, sufficient for common household and industry uses, with an accuracy of ±3°C or ±5%, which is good for general spotting of heat issues but not for precise scientific work.

Buying Guide for the Best Cheap Thermal Imaging Camera
Choosing a thermal imaging camera can be a bit overwhelming, especially if you're looking for a budget-friendly option. Thermal imaging cameras are used to detect heat patterns and temperature differences, which can be useful for a variety of applications such as home inspections, electrical inspections, and even outdoor adventures. To make an informed decision, it's important to understand the key specifications and how they relate to your specific needs. Here are some key specs to consider when picking a thermal imaging camera.ResolutionResolution refers to the number of pixels in the thermal image. Higher resolution means more detail and clearer images. For basic tasks like home inspections or simple diagnostics, a lower resolution (80x60 or 120x90) might be sufficient. For more detailed work, such as professional inspections or research, you might need a higher resolution (320x240 or above). Consider what level of detail you need for your tasks to choose the right resolution.
Temperature RangeThe temperature range indicates the minimum and maximum temperatures the camera can measure. For general use, a range of -20°C to 150°C is usually adequate. If you need to measure extreme temperatures, such as in industrial settings, look for a camera with a wider range, like -40°C to 400°C or more. Think about the typical temperature ranges you will be working with to determine the appropriate range for your needs.
Thermal Sensitivity (NETD)Thermal sensitivity, or Noise Equivalent Temperature Difference (NETD), measures the smallest temperature difference the camera can detect. Lower NETD values indicate higher sensitivity and better image quality. For general use, a NETD of 100mK (0.1°C) is usually sufficient. For more precise work, such as detecting small temperature changes, look for a NETD of 50mK (0.05°C) or lower. Consider how critical detecting small temperature differences is for your application.
Field of View (FOV)Field of View (FOV) describes the area the camera can capture in a single image. A wider FOV (e.g., 50° x 38°) is useful for scanning large areas quickly, while a narrower FOV (e.g., 25° x 19°) provides more detail for smaller areas. If you need to inspect large spaces, a wider FOV is beneficial. For detailed inspections of specific areas, a narrower FOV might be more appropriate. Think about the typical size of the areas you will be inspecting to choose the right FOV.
Battery LifeBattery life indicates how long the camera can operate on a single charge. For occasional use, a shorter battery life (2-4 hours) might be sufficient. For extended use, such as all-day inspections, look for a camera with longer battery life (6-8 hours or more). Consider how long you typically need to use the camera in one session to determine the appropriate battery life.
Display Size and TypeThe display size and type affect how easily you can view the thermal images. Larger displays (3 inches or more) provide a better viewing experience, while smaller displays (2 inches or less) make the camera more compact. Some cameras also offer touchscreen functionality for easier navigation. Think about how important a large, clear display is for your work and whether you prefer touchscreen controls.
Image Storage and SharingImage storage and sharing capabilities determine how you can save and transfer thermal images. Some cameras have internal storage, while others use removable SD cards. Wi-Fi or Bluetooth connectivity can make it easier to share images with other devices. Consider how you plan to store and share your images to choose a camera with the right features.
