Thermal imaging has become more accessible to the average consumer, thanks to advances in the development of low-cost infrared sensors / microbolometers. FLIR was one of the first to make a breakthrough in this segment with the development of the low-cost Lepton sensor (80x60) that was used in the first-generation FLIR One Thermal Imager for iPhone 5/5s. In the meanwhile, Seek Thermal, a startup, debuted their low-cost microbolometer (206x156) in the Seek Thermal Infrared Camera.
In 2015, FLIR continued to make advancements in the sensor space with the launch of the Lepton 3, a 160x120 microbolometer. This sensor was used in the second-generation FLIR One cameras (including the Android version that we have been using in our reviews of mini-PCs). Seek Thermal, on the other hand, had entered the market with a higher resolution sensor. So, their focus has been on developing new products to widen the appeal / addressable market for that sensor. At CES 2016, FLIR demonstrated a couple of new products based on the Lepton sensors, while Seek Thermal showed the products introduced through the course of 2015.
The FLIR Scout TK is a stand-alone and rugged thermal camera with specifications similar to the FLIR ONE (i.e, the same 160x120 Lepton 3 sensor), but, meant for outdoor use. It comes with storage for photos and videos, and they can be transferred to a computer for further review. The FoV is narrow, meant more for viewing objects / animals up to 90m away. There is a 640x480 LCD display on one end, and the industrial design allows for one handed operation. The intended use-case is outdoor enthusiasts who want to spot wildlife in the night or in low light situations, as well as those interested in personal and home security. The product uses an internal Li-ion battery that is rechargeable. It can support up to 5 hours of continuous operation with a fully charged battery.
The TG130, a entry-level spot thermal camera for home and small businesses. It is based on the first-generation Lepton core (80x60 sensor). It is targeted at home users who want to find out insulation issues (places of heat loss in a house). It can also help in determining correctness of HVAC operation, electrical equipment troubleshooting, and refrigerator maintenance. There is no storage media to record to, as the usage involves pointing and clicking to freeze the image with the temperature being part of the OSD. The product uses 3xAAA batteries. It can support up to 4 hours of continuous operation with one set of fully charged batteries.
At the FLIR booth, we had the chance to see working models of both the Scout TK as well as the TG130 along with a host of other thermal imagers from FLIR targeting the professional market. The Scout TK and TG130 are both slated to ship later this quarter.
The Scout TK will be priced at $599, while the TG130 will be priced more economically at $249 due to the use of the first-generation Lepton sensor and lack of any recording capabilities.
Seek Thermal was showing off the camera models introduced over the course of 2015 at CES. These included the Compact and Compact XR thermal imaging cameras. The Compact is suited for indoor analysis while the Compact XR is suitable for outdoor use. They are both available in iOS and Android versions. The main difference between the first-generation Seek Thermal Infrared camera that we reviewed and the Seek Thermal Compact / Compact XR is the availability of zooming capabilities for better focus on the area of interest in the latter. The availability of the 'optical' zooming feature enables the Compact to have a range of 300m and the Compact XR to have a range of 550m (compared to the 90m range of the equivalent FLIR cameras). The Compact (indoor use) has a 36 degree FoV, while the Compact XR (outdoor use) has a 20 degree FoV.
The offerings from FLIR and Seek Thermal have given consumers a wide range of thermal imaging products to choose from, depending on the intended use-case. We would like to see FLIR improve their Android app for better compatibility with a wider range of mobile devices. Hopefully, a future update to the Lepton series would help them achieve resolution-parity with the Seek Thermal sensor. That said, FLIR's MSX (one of the proprietary features of some of FLIR's cameras that blends the output of an image sensor and the output of the thermal sensor) seems to make up for the disappointing thermal sensor resolution to some extent. On the other side, we would like to see if Seek Thermal can bring in thermal sensors with better resolution at similar price points. On a common note, government restrictions still prevent thermal imagers from offering greater than 9 FPS for videos without going through extensive paperwork. Hopefully, the advent of low-cost thermal imagers like the ones from FLIR and Seek Thermal can help in making this situation better.

Lord of the Bored - Wednesday, January 27, 2016 - linkOr he could get an infrared lamp, and then he can see the reflected light from his invisible flashlight. IR night vision IS a thing.
It'd probably get confusing with the temperature color-coding applied, anyways. But whatcha gonna do? Buy a real night-vision scope? That's the chump's way, even if it IS half the cost of a FLIR sensor module on Amazon, and not available for shipping to California/outside the US.
Mr Perfect - Tuesday, January 26, 2016 - linkSo for $250 I can either have the 80x60 FLIR TG130 with no recording or the 206x156 Seek Compact with recording. Not a hard choice.
AngelOfTheAbyss - Tuesday, January 26, 2016 - linkFor smartphone-free operation you can choose between FLIR TG130 (80x60, no recording, $249) and Seek Reveal (206x156, recording, $399).
If you want to use your smartphone the choices are Seek Compact (206x156, $249), Seek CompactXR (206x156, $299) and FLIR ONE (160x120, $249).
Mr Perfect - Wednesday, January 27, 2016 - linkYes, I know. It was more of a comment on pricing and features. Seeing as everyone basically has a smartphone on their person at all times, I'm just looking at the hardware in the entry level devices regardless of platform. At $250, the FLIRs seem strangely anemic compared to the Seeks.
ganeshts - Wednesday, January 27, 2016 - linkMSX is very impressive once you see it in action. I should have the FLIR One review out shortly comparing the Seek Thermal and the FLIR One shooting the same stuff. You can definitely see the difference in what I would term as 'actionable' quality.
jasonelmore - Tuesday, January 26, 2016 - linki'm interested in the "Reveal" model more than anything else. It's rugged and can easily be carried around in a tool box with a bunch of metal tools and not get banged up. This is a perfect device for a computer hardware reviewer.
cjdipppenaar - Sunday, May 29, 2016 - linkGood Day, looking at your review regarding Seek XR and Flir Scout i am a bit confused, what would your choice be or best choice if you would use it for scanning open areas like open fields or similar, will be mainly used for crime fighting.
