Mobile Thermal Cameras

Just like all things technology, Thermal Imagery is advancing rapidly. In the past year alone there have been some considerable breakthroughs with thermal cameras. As most electronics advance, shrink, become faster and more affordable, so has the thermal camera. Last year in 2014 FLIR discretely unveiled its concept and prototype for a mobile phone mounted miniature thermal camera, the FLIR One.

The world was excited by this news but we all know that when something like this occurs it’s quickly followed by competition. Late last year a new mobile mounted thermal camera was announced called the SEEK Thermal. There are other devices under development but at this stage we have decided to review and compare the FLIR One and SEEK Thermal as they are the only publicly available mobile thermal cameras on the market.



After the buzz that came about the revelation of perhaps the world’s first mobile mounted thermal sensor FLIR released the FLIR One consumer model in 2014. It comes in the form of a two step iPhone 5 or 5s case. The first case is much like a standard hard case (with a FLIR logo) and the second stage a clip on unit that contains the camera sensors and extended power supply for the camera. This duel case system makes it a little clumsy and bulky but you have the choice of only attaching the Thermal Lens unit when required, although this requires you to carry it around with you everywhere, separately.

When operating the thermal camera, the image is visible directly on the iPhone screen. You will need to download the FLIR One app from the Apple app store in order to use it of course.

The app is a breeze to use and is very similar and in-line with other FLIR software. There are all the basic settings such as colour pallet, emissivity settings and basic analysis tools including a lens calibration tool. You can also take thermal imagery in a number of different ways. Still image, time-lapse and video. Although the video will contains no radiometric information.

The FLIR ONE app is available for download from the Apple App Store.
Included accessories: USB charging cable, iPhone case, and jack audio adapter.
Certifications and standards: FCC, CE, RoHS, CAN ICES-3 (B)/NMB-3(B), UL


For a first to market tech product the FLIR One preforms very well. Although as one may guess it has a lot of  space for improvement. Many of these improvements have already been made. FLIR has announced that it will be releasing the second generation FLIR One sometime in mid to late 2015.

Some of the improvements are:

  • More powerful thermal sensor able to capture thermal images four times the resolution of the old FLIR One Leptom sensor.
  • Compact attachable unit that supports Lighting jack and MicroUSB connections. This makes it compatible with a wide range of phones including android smartphones.
  • Pricing to be lower than original release price. Also the original FLIR One will have its price lowered.


Seek Thermal

The Seek Thermal was released into the consumer market at the end of Q3 2014 and was met with positive reviews. It was one of the first competitors to the FLIR One and brought with it some enhancements that are worth serious consideration when deciding to purchase a mobile thermal device.

The first thing one notices is the different form factor of the two cameras. The Seek Thermal has been released as a dongle little larger than the average human adult thumb, where as the FLIR One is a bulky two stage extension iPhone case.

Another positive for the Seek Thermal is the thermal sensor, which is called the “True Thermal Sensor,” it’s in fact a vanadium oxide microbolometer which is capable of detecting long-wave infra-red between 7.2 and 13 microns. This gives you a thermal sensor with a total of 32,136 “Thermal Pixels” spread across a 206-by-156 pixel array. This is a far larger sensor than that of the Lepton sensor in the FLIR One which is a mere 80 x 60 thermal pixels. This means that the overall thermal image is more prises as there are more points of measurement.

Although the thermal image is higher in accuracy and sharper than the FLIR One images, the FLIR One attempts to step around this with FLIR’s MSX feature. MSX artificially enhances the thermal image by combining the thermal image with a higher resolution digital image to output a clearer and easier to interpret thermal image, albeit not as accurate.

One last thing that may put the SEEK Thermal a little further ahead of the FLIR One (first generation 2014) is the price tag at almost half the price.

Much like the FLIR One, SEEK Thermal is soon releasing its own new and improved version with the SEEK Thermal XR. The new model will showcase a manual focus lens as well as the ability to optically zoom in on your targets, something even some high end thermal cameras lack.

Something tells me that this is just the beginning, competition is always good for advancement.

As many of you may have read on our Blog a few months ago, FLIR showcased a new gadget – a FLIR thermal camera sensor and lens built into a custom iPhone case, thus creating something that had not been seen before: a mobile phone capable of capturing and editing actual thermal imagery.

Unlike many prototypes that made it no further than the concept stage, FLIR has pushed their prototype Thermal Camera iPhone case into consumer production.  The FLIR One, as it’s called, is now available for purchase for less than $350 USD.  Some may think that $350 is a lot to pay for an iPhone case with another camera on it, but compared with it’s closest living relative, the FLIR E4, which is priced at around $1600 AUD, it’s a no-brainer.

With the FLIR One, small business owners and enthusiast now have a way to see what’s hot and what’s not without breaking the bank.  But remember, for all the big boys, FLIR has a large range of hand held and fixed thermal cameras that are sure fit your needs.

FLIR’s prototype iPhone Thermal Camera attachment

Almost every one has a smart phone these days and among the most popular is the apple iPhone.

The iPhone is a sleek robust user friendly device that allows you to play games, surf the net, take photos and make the occasional phone call. Now it can do one more thing.

With the Help of FLIR you can now use your iPhone to take Infrared Images. The FLIR prototype iPhone attachment allows the user to look at the world around them in the infrared spectrum and take thermal images of practically anything they can point at.

At the heart of the unit sits FLIR’s new Quark core which is small enough at three quarters of an inch to enable the capture of images at .3 megapixels or 640 x 480 pixels. A 13 mm lens mounted on the back just above the iPhone’s own camera allows the user to capture detail from more 100 meters away. The unit also comes with it’s own battery supply so it won’t put an extra burden on the iPhone’s power.

Although this is a commercial prototype it has caught the eye of the military who want it implemented onto troop gear such as guns and helmets. But for this prototype to become commercially viable it will ultimately have to drop a few pounds. The image quality and resolution, and the thermal sensitivity will suffer here in order to make the devices cheap enough to build thus making them affordable for the target market.

FLIR’s iPhone Thermal Camera attachment will be available in the very near future.
