Best Thermal Cameras for Phones (2022): Flir, Seek Thermal, Uni-T, Perfect Prime

by admin

The Flir One Gen 3 is the largest thermal camera I’ve looked at. At about 2.6 inches wide and 1.3 inches tall, it fits in this space, including the internal battery and his two cameras. It’s also the most complicated camera I’ve seen. This large camera body has rounded edges, two rubber grips on the sides, and a USB-C plug that fits into the USB-C port on top (the iOS version has a Lightning plug). increase. in place.

Flir saves images at a whopping 1,440 x 1,080 pixel resolution, which is a bit of a trick.well, maybe cheating Too strong a word, but there’s a magic trick going on here. The infrared sensor only captures images of 80 x 60 pixels. To create a high-resolution image, the device smoothes and magnifies the low-resolution thermal image and combines it with a much higher-resolution visible-light image from her second camera, right next to the infrared camera. . Yep, this device adds two cameras to the multiple your phone already has.

It may be a little sneaky, but it works. The visible light camera adds a ghost-like edge drawing effect to the image. This is very helpful when trying to identify the source of heat, such as which side of a window is leaking warm air, or which component on a circuit board is overheating. Provides a visual map.

The downside of this complexity is that it requires more power. To handle this, Flir includes an extra battery in the camera, which must be charged through the USB-C port on the bottom of the device. The camera won’t work until it’s charged. Also, after connecting the camera, you need to press the button on the bottom of the device to turn it on. Then wait about 20 seconds for the Flir One app to launch ( iOS When android) detects the camera. The images you get are great, but everything feels too complicated compared to other cameras.

The problem with this (and other infrared cameras) is that they plug into the phone’s charging port. If your phone has a case, the device may not fully connect. However, the adjustable plugs here are a great solution. Twist the wheel under the connector to move it up and down to adjust the length to fit different thickness phone cases. To use the Seek Thermal and Prime Perfect cameras, I had to remove the case from the phone or use an extension cable. However, the Flir One Gen 3 worked in my his Fold 4’s rather chunky Samsung case.
