10 Best Cheap Thermal Imaging Camera 2025 in the United States

The FLIR ONE Gen 3 thermal imaging camera is a compact and convenient option for iPhone users looking to add thermal imaging capabilities to their device. It directly connects to iPhones with a Lightning port, making it easy to use on the go. With a thermal resolution of 80x60 and a visual resolution of 1440x1080, it provides decent image clarity for basic tasks like detecting heat loss in homes, identifying electrical issues, or inspecting mechanical equipment.

A notable strength of this camera is its accuracy in measuring temperature within ±3°C, which is sufficient for most DIY and casual applications. The ability to upload and share images via FLIR Ignite Cloud is also a big plus for users who want to organize and access their thermal images easily.

On the downside, the thermal resolution may not meet the needs of professional users requiring higher precision and detail in thermal imaging. The temperature range is somewhat limited, operating effectively between 5°C to 120°C, which could be restrictive for more specialized applications. Additionally, while the camera is designed to endure job site conditions, it still requires careful handling to avoid damage, especially considering that it's an accessory rather than a standalone device. Battery life is generally good, but the dependency on the phone’s battery for operation can be a drawback during extended use. Furthermore, this product is designed specifically for iOS devices, meaning Android users need to look elsewhere.

The FLIR ONE Gen 3 is a solid choice for casual users and DIY enthusiasts interested in thermal imaging at an affordable price. However, for professionals or those needing more advanced features, this might not be the best fit.

The HP96 Thermal Imaging Camera stands out with its impressive live super resolution feature, enhancing the thermal image clarity from 96x96 to 240x240, making it suitable for detailed inspections. The dual cameras, including a 96x96 IR camera and a 640x480 visual camera, offer five image modes and eight color palettes for versatile use in different scenarios. This camera is easy to operate, thanks to its 3.5-inch touchscreen with a user-friendly interface, making it accessible even for less tech-savvy users.

The built-in eMMC storage and microphones support live video and audio recording, while the LED flashlight aids in low-light conditions. The 50-degree field of view provides broad coverage, and the device tracks maximum, minimum, and center temperatures for quick anomaly recognition. Additionally, its advanced VOx detector ensures accurate temperature readings with a discrepancy within ±2%, and the adjustable emissivity settings enhance accuracy across various materials. Durability is a strong point, with the camera featuring a 6.6ft drop test rating and IP54 protection, allowing it to withstand harsh environments.

The built-in rechargeable battery offers up to 4 hours of continuous use, which is decent but might require frequent recharging for longer tasks. The storage capacity of approximately 30,000 images and 20 hours of video is sufficient for most users. Its compact design and lightweight build make it portable and easy to handle. This camera is a solid choice for those seeking a budget-friendly thermal imaging solution with reliable performance, although the battery life might be a limitation for extended use.

The FLIR TG165-X Thermal Imaging Camera stands out as a solid option in the cheap thermal imaging camera category, especially for those needing a reliable tool for building inspections, HVAC, and electrical work. One of its main strengths is its impressive resolution of 48,000 pixels, which allows for clear thermal images. This is further enhanced by FLIR's patented MSX technology that combines visual and thermal images, making it easier to interpret data. The temperature range is quite broad, spanning from -25°C to 300°C (-13°F to 572°F), catering to various inspection needs.

The camera also features a built-in laser pointer, which helps users quickly identify measurement areas. Its rugged design is a plus for professionals working on-site, offering an IP54 rating that protects it from dirt and moisture. Battery life is commendable, supported by a rechargeable lithium-ion battery, ensuring you can work without frequent interruptions. Additionally, the lengthy warranty, including 10 years on the detector, showcases the manufacturer's confidence in its durability.

While it provides good thermal sensitivity, the NETD (Noise Equivalent Temperature Difference) isn’t specified, which could be an important factor for some users looking for precise readings. The display, although functional, is basic, and those seeking higher-end features, like Wi-Fi connectivity for image sharing, might find it lacking. Additionally, while the camera is lightweight, it may not have the advanced features found in pricier models, which could limit its appeal for more experienced users. The FLIR TG165-X is a user-friendly and effective thermal imaging camera for budget-conscious buyers looking for essential features for inspections and maintenance, but it might not meet the needs of users requiring advanced capabilities.
