When we are talking about a thermal camera that is designed to be used together with a smartphone or a tablet we presume that it needs to be a low-end and affordable solution. Well, that is not always the case as we can see with the Therm-App from the Israeli company Opgal. The main goal of the Therm-App accessory for Android mobile devices is to turn smartphones into powerful thermal cameras, featuring high-resolution thermography and long range, enhanced night vision capabilities. The Therm-App comes with a thermal imager with a resolution of 384×288 pixels that previously was only available on standalone professional thermal imaging cameras and thermography devices. The lightweight and compact Therm-App device fits multiple phone models. It can also be mounted on any tripod or camera handle using its standard connector. With its interchangeable lenses system, the Therm-App device provides effective detection of faraway targets through its long range (19mm) lens, and a wider view through its 6.8mm lens. Its 8.7Hz FPS version is export license free. The only thing that you might not like much about this accessory is the price, it is currently available for $1600 USD, though for the resolution and features it offers you canot expect it to be very cheap.

Specifications wise there is one important thing worth mentioning that can be considered as a bit of a disadvantage – the temperature range that the thermal camera accessory can detect. The operating range of just 5 to 90 degrees Celsius is pretty limiting and with a larger resolution thermal imaging sensor we kind of expected to see a wider detection range available as well, especially considering the price of the Therm-App device. Other than that the device does look pretty cool with its design allowing the user to also swap lenses depending if a longer or shorter detection range is required – based on the kind of use you are planning to go for. The sample thermal images captured with the high resolution thermal imaging sensor do look very nice in their original resolution and with some interpolation they they be perfect for use for visualizations and thermal reports, that is if the temperature range of the Therm-App is enough for your needs.
