The InfiRay Thermal Monocular T2 Pro is a solid choice if you're looking for an infrared camera that pairs with your iPhone, especially for outdoor activities like hunting. It offers a decent 256x192 infrared resolution, which delivers clear thermal images, helping you spot animals up to 800 yards away with smooth visuals thanks to its 25Hz refresh rate. The 2x to 16x zoom adds flexibility, letting you focus in on targets at different distances with good accuracy. It connects easily to your phone and uses your phone’s battery, providing around 8 to 10 hours of use, which should be enough for a full day of exploration without charging worries.

The device supports multiple image modes and lets you capture videos and photos, which is great for documenting your adventures. Its plug-and-play design means setup is straightforward without complicated steps. At just over 2 pounds and relatively large dimensions, it might feel a bit bulky to carry around for long periods.

This thermal monocular is best suited for hunters and outdoor enthusiasts who want a compatible, easy-to-use thermal imaging device with good range and image quality. However, those needing detailed environmental specifications or ultra-portability might need to consider other options.

The TOPDON TC002 Thermal Camera is designed specifically for iOS devices, making it a great tool for those who use iPhones or iPads. With a resolution of 512 x 384, it provides clearer thermal images compared to many competitors, enhancing visibility with features like adjustable sharpness and contrast. The temperature range of -4°F to +1022°F, coupled with a sensitivity of 40mk, allows for precise temperature readings, making it suitable for professionals like HVAC technicians, electricians, and home inspectors who need accurate data in various conditions.

One of its notable strengths is the ease of use; simply connect it to your device and download the necessary app for immediate functionality. The compact size and lightweight design (1.1 oz) make it convenient to carry around, which is beneficial for fieldwork. Additionally, the battery life is decent, capable of lasting 6-8 hours when connected to a fully charged iPhone and even longer with an iPad.

However, there are a few drawbacks to consider. Firstly, the camera is limited to iOS devices with a Lightning port, meaning Android users or those with Macs cannot utilize this product. Also, while the product is portable, its reliance on specific device compatibility might limit its user base. The effective distance of 16.4 ft is adequate for most applications, but some users might prefer a longer range for certain tasks. Lastly, while the camera offers various visual modes and palettes, mastering all its features may require a learning curve for those unfamiliar with thermal imaging technology.

The FLIR ONE Pro is a compact thermal camera add-on designed specifically for iPhones with USB-C ports, starting from the iPhone 15. It offers a native infrared resolution of 160x120 pixels, enhanced up to 320x240 pixels using FLIR’s Super Resolution technology for clearer thermal images. This resolution is sufficient for spotting temperature differences but does not match professional standalone devices with higher resolution sensors. The camera measures temperatures accurately within ±3°C or ±5% in typical home and jobsite conditions, covering a useful range from about 5°C to 120°C. Its visual camera features a 640x480 resolution and includes MSX technology, which overlays real-world details on thermal images, making it easier to interpret what you’re viewing.

The device connects directly to your phone’s charging port and works seamlessly with compatible iPhones, offering user-friendly operation.

Additionally, the FLIR ONE app provides step-by-step inspection guides, helping non-experts identify common issues such as air leaks or moisture.

This camera is best suited for casual or semi-professional use rather than high-precision industrial work due to its moderate resolution and temperature range. It is compatible only with newer iPhones featuring USB-C ports, making it unavailable for Android users or owners of older iPhone models. The FLIR ONE Pro delivers a strong balance of usability, image quality, and durability for iPhone owners needing a convenient thermal camera for home inspections, maintenance, or DIY projects.
