Top-10 Cheap Thermal Imaging Camera
Loved in the USA

The FLIR ONE Pro is a thermal imaging camera designed for iOS smartphones, specifically for iPhone models with USB-C (iPhone 15 and newer). It offers a thermal resolution of 160x120, which is quite impressive for a budget-friendly device. This resolution allows you to capture detailed thermal images, complemented by a visual resolution of 1440x1080 for clarity. The camera can measure temperatures with an accuracy of ±3°C, making it suitable for various applications like home inspections or basic maintenance tasks.

One of its standout features is the integration with the FLIR Ignite Cloud, enabling easy upload, organization, and sharing of images directly from the device. This feature is particularly convenient for users who need to manage their images efficiently. The camera is also designed to withstand jobsite conditions, being resilient to drops from up to 1.5 meters.

However, the camera is limited to certain iPhone models, which could be a drawback for users with older devices. The product does not have a zoom feature, which might limit its usability in scenarios where close-up inspection is required. Additionally, the temperature range (5 °C – 120 °C) and thermal sensitivity might not suffice for more advanced thermal imaging needs. At 7.7 ounces, it is lightweight and portable, making it easy to carry around. It is an excellent choice for users seeking a balance between cost and quality for basic thermal imaging tasks.

The Bosch GTC600C 12V Max Connected Thermal Camera is a solid choice for those seeking an affordable thermal imaging tool suitable for both indoor and outdoor use. It offers a broad temperature range from -4°F to 1112°F, which covers most common applications like home inspections, electrical work, and HVAC troubleshooting. The camera can store up to 500 sharp thermal images, making it useful for documentation. Its 12V Max lithium-ion battery provides reliable power, and the device's ergonomic design ensures comfortable handling during extended use.

One standout feature is the built-in microphone and speaker, allowing you to add voice notes to images for easier on-site documentation—a handy tool if you need to explain findings without writing everything down. The camera also connects via Wi-Fi to Bosch’s app, making image sharing and report creation straightforward. The 500-millisecond response time is decent but not the fastest if you need quick readings. Battery life is good due to the interchangeable Bosch 12V system.

This camera suits DIYers, contractors, or hobbyists looking for a dependable, easy-to-use thermal imaging tool without breaking the bank, though professionals requiring very high resolution or sensitivity might want to explore pricier options.

The HSFTOOLS HF96V thermal camera is a solid choice if you're looking for an affordable device with features that punch above its price. It offers a thermal resolution of 96x96 pixels, which is enhanced in real time to 240x240 using its live super resolution technology, giving clearer images than typical low-res cameras. Its temperature range is very broad, from -4°F to 1022°F, making it suitable for various tasks around the home or workplace. The thermal sensitivity is good enough to detect small temperature changes, helping you spot issues like leaks or insulation gaps more easily. The 50° field of view is wider than many cheap models, meaning you can scan larger areas without moving the camera too much.

It has a built-in visible camera and offers different image modes and color palettes, which helps in understanding what you’re looking at and improves anomaly detection. The device is easy to handle with one hand, includes a laser pointer for pinpoint accuracy, and supports live screen sharing to a computer via USB, which is handy for detailed inspections or presentations. Temperature readings are reported accurately within ±2%, and you can adjust settings for different materials, adding to its reliability. The lightweight design and included rechargeable battery suggest decent portability for field use.

One downside is that the base thermal resolution, before enhancement, is on the lower side compared to more expensive models. Also, while the camera has IP54 rating, it offers moderate protection against dust and splashes but isn't fully rugged for harsh conditions. This camera suits homeowners, hobbyists, or professionals needing a budget-friendly thermal camera that doesn't skimp on useful features and accuracy, especially for building inspections, electrical checks, or general maintenance.
