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

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

Fortunately 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 Pro is totally different, as a result of it makes use of Wi-Fi to hook up with your cellphone. That means it doesn’t should be bodily plugged into your cellphone and even located close by. My Samsung Fold 4 may connect with the ad-hoc Wi-Fi community that the FLIR One Edge Pro created as much as a distance of about 20 toes. Since the cellphone and digicam can function independently, it is a lot simpler to see into confined or hard-to-reach areas with out worrying about dropping the costly cellphone your digicam is tethered to. However, at $550, the One Edge Pro may cost as a lot as your cellphone.

Bring the Heat

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

The machine costs by way of the USB-C port on the aspect, and a single button on the entrance turns the digicam on. The FLIR One app controls all the pieces else. Near the highest of the physique are two cameras: a 160- by 120-pixel infrared digicam and a 640- by 480-pixel seen mild digicam. In customary lighting, the pictures from the 2 cameras are mixed to provide 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 slightly grandiose title of Multi-Spectral Dynamic Imaging. These dynamic visuals might be saved as 640- by 480-pixel pictures or as a video that runs at about 9 frames per second—slightly uneven, but it surely’s a limit imposed by the US government on know-how that could be exported.

The FLIR One Edge Pro 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 might be modified, however the default makes use of the colours you’d usually see when an infrared digicam is used on a TV present: Cold objects are blue, and heat objects are crimson.

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

When clipped onto my Samsung Fold 4, the FLIR One Edge Pro stayed firmly in place, but it surely felt prefer it may slip off at an inopportune second. I discovered myself instinctively conserving a agency maintain on each the digicam and the cellphone.

Working with the digicam indifferent from the cellphone, the FLIR One Edge Pro feels very snug. It is simple to carry in a single hand and transfer nearer to look at a warmth supply with the cellphone within the different hand. I’d have favored a tripod socket on the underside of the digicam module to make it simpler to connect to issues with a versatile tripod just like the Joby Gorillapod. That would make it simpler to observe the temperature of one thing over an extended time frame.
