FLIR One Edge Pro Review: Thermal Images and Videos From Any Phone

Are you a zebra fish? If not, you’re lacking out on one thing: the flexibility to see infrared mild, the thermal radiation past the scope of human imaginative and prescient given off by all the things round you.

Fortuitously for these with out the Cyp27c1 enzyme that allows zebra fish to see infrared light, thermal cameras—just like the $550 FLIR One Edge Pro—can seize in any other case invisible infrared mild, and in doing so present us how heat or cool the issues round us are. That’s a helpful trick for plenty of causes: Zebra fish can see meals at nighttime, householders can see the place the warmth is escaping from their homes, and I can see the place my canine is within the yard at 3 am on a chilly night time. 

Many thermal cameras can be found that plug into your smartphone; I reviewed several in our recent roundup. The FLIR One Edge Professional is totally different, as a result of it makes use of Wi-Fi to hook up with your telephone. Meaning it doesn’t need to be bodily plugged into your telephone and even located close by. My Samsung Fold 4 might hook up with the ad-hoc Wi-Fi community that the FLIR One Edge Professional created as much as a distance of about 20 ft. For the reason that telephone and digital camera can function independently, it is a lot simpler to see into confined or hard-to-reach areas with out worrying about dropping the costly telephone your digital camera is tethered to. Nevertheless, at $550, the One Edge Professional may cost as a lot as your telephone.

Deliver the Warmth

The FLIR One Edge Professional is a tall and skinny module, slightly below 6 inches lengthy and about 1.5 inches extensive. It’s formed like a C clamp, with a spring-loaded prime arm that clamps onto your telephone’s again. This design seems to be a bit wack, nevertheless it works: It fitted onto a number of Samsung and Apple iPhones, with and with out circumstances.

The system prices by way of the USB-C port on the aspect, and a single button on the entrance turns the digital camera on. The FLIR One app controls all the things else. Close to the highest of the physique are two cameras: a 160- by 120-pixel infrared digital camera and a 640- by 480-pixel seen mild digital camera. In normal lighting, the pictures from the 2 cameras are mixed to offer you an image with the invisible element of the thermal picture overlaid on prime of the seen mild picture; a course of FLIR offers the somewhat grandiose identify of Multi-Spectral Dynamic Imaging. These dynamic visuals may be saved as 640- by 480-pixel photographs or as a video that runs at about 9 frames per second—somewhat uneven, nevertheless it’s a limit imposed by the US government on expertise that is perhaps exported.

The FLIR One Edge Professional can measure temperatures wherever between -4 and 752 levels Fahrenheit by way of two switchable ranges, one that may see temps from -4 to 248 levels Fahrenheit and a second that may see from 32 to 752 levels Fahrenheit. In each ranges, the colour scheme of the captured picture may be modified, however the default makes use of the colours you’d usually see when an infrared digital camera is used on a TV present: Chilly objects are blue, and heat objects are crimson.

The digital camera’s default setting combines pictures from each cameras, so you may see an “define” of a real-world object coloured in with the temperature info. You may select to view simply the IR or seen mild pictures. These settings may be chosen within the FLIR One app, which is obtainable for iOS and Android. This app controls the digital camera and retains a library of saved pictures and video; no knowledge is saved on the digital camera itself. This easy-to-use app means that you can management how the sensors’ temperature measurements are displayed within the pictures and movies, both by marking the most popular and coldest spots with crosshairs or setting as much as three spots within the picture to be repeatedly measured, which is particularly helpful in video mode.

When clipped onto my Samsung Fold 4, the FLIR One Edge Professional stayed firmly in place, nevertheless it felt prefer it might slip off at an inopportune second. I discovered myself instinctively protecting a agency maintain on each the digital camera and the telephone.

Working with the digital camera indifferent from the telephone, the FLIR One Edge Professional feels very comfy. It’s straightforward to carry in a single hand and transfer nearer to look at a warmth supply with the telephone within the different hand. I’d have appreciated a tripod socket on the underside of the digital camera module to make it simpler to connect to issues with a versatile tripod just like the Joby Gorillapod. That may make it simpler to observe the temperature of one thing over an extended time frame.
