[@SteveHartmanVideos]

when you save the images, does it save two at once, one for IR and one for visible? or does it take "what you see" in terms of blending when are looking at the screen with the blend setting?

[@ChrisCorbettFPV]

I'm interested in how this functions in the dark, and outside as well, any chance of a follow up?

[@arminbaumgardt4622]

How accurate are the displayed temperatures? Btw: Good video!

[@learnelectronics]

Nice video Julien. I've been wanting one of those.

[@tin2001]

There appears to be a gun style version with the same sensor for about the same price. It's in the crazy sale link in the description. Still too expensive for me though.

[@monergy11]

Julian, just received my HT-A1 today and although it does everything you demonstrated I wonder what is the purpose of the LED? no menu function or auto light up in dark areas if taking a normal photo? I do like it, higher res than my Flir One (Iphone) but a little bit flaky in places. Any chance of a teardown?

[@Electronieks]

Flir components inside?

[@shahidsuri]

can the HT-A1 look inside walls to inspect hot water pipes?

[@sa8die]

what do you think of the "seek thermal" type?

[@chax1980]

Can the captured photo be save from the camera to your PC?

[@TheDefpom]

I purchased one of those ht02 some time ago from aliexpress , it had a manufacturing fault, I did a repair video on it, which turned out to be a reversed tantalum cap! That new camera looks pretty good, should be for the price.

[@kevinlin7576]

Hello! HT-18 is hot in the US Amazon, and sales are the first in the industry., its quality and function has been affirmed, its price is an advantage, you can also consider working with us, we provide supply,Open up a new market.Towards fortune The Freedom Trail.

[@pyt22fr11]

Very useful comparative review, thank you and congrats !

[@SuperDjavol]

hi bro,nice video... does this device have zoom?

[@daslolo]

can you lock the range?

[@rodrigomartins3399]

Hello, do you have some review of CAT S62 pro ?

[@MoesKeckeEcke]

How does this compare to professional offerings from flir and seek? Especially the mobile phone extension cameras? I know the resolution is usually lower on the upmarket ones but SOFTWARE?? How does it compare to a flir portable camera?

[@joinedupjon]

12:43 I was starting to get worried when you started pointing at hot diode packages with the metal tip of your mechanical pencil. colour contrast on the high/low cursors could imo have been better implemented, it didn't seem to care if it was putting white text over a pale part of the image

[@ADR69]

$410USD if anyone is wondering

[@pev_]

Yeah, how can this be so expensive?? I don't see the technology being very special. EDIT: Oh, sorry, Julian did say a bit about that, being due to the sensor having low production quantities. EDIT2: But still, annoyingly expensive :)

[@GLITCH_-.-]

Yeah... one of these little things you put in your smartphone has a 320x240 sensor. I forgot which one, but it was less expensive. EDIT: Not the Flir ones. The other ones.

[@Okurka.]

$410 for something from BangGood? No, thanks.

[@dlinnoedlinnoe]

Seek Thermal. Great one.

[@Kamikazeee1337]

I don't get the prices on these things. Every smartphone today has a camera with a >10 mega pixels that mostly costs less than 10 dollar to replace. I get that these sensors are for visible light but does that make that much of a difference? If I had to guess I would say it has to be the other way around because a normal camera has to sense a far wider spectrum of wavelenghts than the "narrow" IR. I would understand if they cost twice as much but the reality is they give you the resolution of a camera in the 90s and charge you more than 10times the price. This can not be the smaller production figures alone.

[@Ziplock9000]

I'd really love one of these or a good way of testing the temps of certain components. An IR gun can't be aimed correctly and a thermocouple doesn't make good thermal contact.

[@raykent3211]

Nice video, Julian. I appreciate the stuff on IR emissivity and transmissivity, which used to bewilder me.

[@JulianIlett]

Thanks Ray - I remember playing with the emissivity setting on the HT-02 and still not fully understanding what was going on. Playing with this device for a couple of hours really helped me understand what I was looking at :)

[@umbratherios5614]

isn't the ht-02's sensor 32x32 pixels, not 60x60?

[@vm16534]

Can You Do The LED Light Kit Build?!

[@gudenau]

I just want to open that up to see if it can't be soft modded.

[@gatienbecker9320]

hello, can you film with these camera?

[@jasejj]

How much? You can get a proper Flir for that.

[@zaprodk]

The clicking inside the camera is the calibration shutter.

[@JamesPotts]

Yep. The sensors need to periodically calibrate with an even input. I worked on a project with an IR sensor, and it couldn't have an automatic shutter (for reasons I don't recall). The result was you had to manually calibrate it every so often, by covering the sensor. Otherwise, you'd start getting fake heat signatures building up.

[@heikovanderlaar3780]

Mike Harris mikeselectricstuff explains and shows that nicely in one of his videos on thermal imaging cameras. Worth a watch, Julian.

[@JulianIlett]

I think I watched it some time ago - I'll have another look, thanks :)

[@joruss]

It clicks because of sensor being periodically calibrated. BTW. if you plan to post images somewhere make sure you processed them in graphics program first (open/save shoud do the trick) Most likely these jpegs contain both IR and visible image data... or at least flir One does that. One can get these images load into the app and get the visible light photo out of it.

[@californiakayaker]

I can imagine some great uses for that. Finding connections in high amperage situations that are getting warm or hot. Such as those used with electric motors. I'm also surprised that you aren't allowed to move on or the other images and align them with software in the unit. I suppose that capability will be added eventually.

[@californiakayaker]

I've seen a situation where an EV boat burned up connections on a battery. There were multiple batteries and a look with an IR gadget like this would have quickly shown there was a problem, saving an expensive battery and nearly burned up boat ! But even my cheap IR viewer would have probably done the same for them. This device is far more complex and capable of far more detail.

[@John-gm8ty]

hmm if that is 32c in an 18c ambient, I wonder what it would be here in Brisbane Australian on a 38c night? toasty I'm sure.

[@fersunk]

The seek compact cost about $250 with a focusable lens and a 206*156 sensor. And the compact pro has a resolution of 320*240 for $500. Why I should buy this thingy at the cost of a thermal camera of higher resolution and a reputable brand?

[@pirateman1966]

Thanks for the info. I was gonna buy one. I will buy the seek compact for my android phone instead.

[@GlennnD]

Because the app needs to use Location and microphone for what? More spying for data?

[@k7iq]

I don't think I have seen anywhere about the HT-A1's image storing or if it even stores (slow) video and storage amount ? I have seen that it has 9 updates per second though. OK, just found this Image storage ：8G but now video I guess. Can do that externally with a camera or maybe over the USB ?

[@JulianIlett]

I think it only stores stills

[@k7iq]

Thanks. I think you're right since another one of their IR cameras says it does video. That's OK. I was thinking though... Could design and 3D print a camera holder that could video the screen of whatever IR camera. Even one of our cheap FLIR cameras doesn't to video. The more expensive ones do. It's hardly needed but can be handy for circuit measurement work.

[@JulianIlett]

The HT-A1 will feature in my next video - there are some concerns about its battery.

[@trottx]

This would be a budget buster for my ebay/China "inexpensively" sourced electronics hobby.

[@thermalmeow7199]

I bought a thermal imager similar to 2:47 ---- I really wanted to get the Bochs GTC400 but my budget is limited, wished I could have that for my KZbin channel use

[@billpeiman8973]

C$469 at Newegg; no Google results found for HT-A2

[@pvc988]

Would be nice if you could manually offset optical camera image to match thermal one. Or even better if software could do it automatically.

[@ExtantFrodo2]

and manually focus as needed. I'm not sold one any of these yet. I want one for many reasons including imaging my body for health concerns. So far I see nothing worth writing home about.

[@LaurentSOUDRON]

Thank you very much for the video which helped me to decide. I just found a used HT-A1 at a decent price for my small budget of poor man.

[@highflowhighflow9896]

the Flir one does much better to align the thermal and visual image in mixed mode , i am very satisfied with it and mainly use it for electronics

[@ljprep6250]

Maybe it's the great software or a more balanced optical/IR integration, but even with a smaller 80x60 sensor the Flir C2 seems head and shoulders above this one for $90USD more. Thanks for the review. I need the focus-free type imager for construction use. Does Banggood give those to you, or require purchase or return? Good review, BTW.

[@RichardT2112]

18:15 case of the transporting/teleporting screw!

[@FlyingShotsman]

For anyone who's interested, Martin J. Lorton did a series of videos on how these cameras work, and reviewed a number of them. Tutorials: kzbin.info/aero/PLDBuVMDVJaX22M90Agzj86rx1DrQoBDrv Reviews: kzbin.info/aero/PLDBuVMDVJaX1QHt-na-_fr9FgiY5mjIo2

[@simontay4851]

How does it compare to the flir one version 2, the thermal camera that plugs into your android device and flir e4? What is the resolution of them?

[@Jeremy-su3xy]

Is it a Chinese company product?

[@korishan]

13:55 "Oh, that's my wife!" Then you should of said something like "Look how hot she is" or "Isn't she a hottie" ;) brownie points Julian, brownie points :P

[@phizicks]

"Let's see how hot she gets when I piss her right off, oh look, it does work"

[@TheDefpom]

Such a missed opportunity...

[@uK8cvPAq]

What happens if I point it at a neighbors house at night? Could I watch them messing around? Non of them have insulation around here.

[@JulianIlett]

Fortunately (for your neighbours), you're unlikely to be able to see through their walls :)

[@uK8cvPAq]

hmm what about tents then?

[@JulianIlett]

That might work.

[@MaxSMoke777]

For those of you that don't understand why this is over $400, even at cheap Chinese prices, you should know just how expensive every pixel of Thermal detection is. For the FLIR ONE, which is cellphone based, it has a resolution of 80x60. That's $200. The upgraded version, the FLIR ONE Pro, which does 160x120 pixels is $399. This does 220x160, which in terms of a Thermal camera is next to Pro level. Most cameras in that range start at $600 to $1000. SEEK at a good one for $600. You can get HD quality Thermal, but those start at well over $5000. This camera is quite a bargain. I have an older SEEK Thermal, which is quite a bargain itself at 206x156 pixels, albeit at a slow and somewhat glitch frame-rate. Thermal imaging is amazing, but it's far from cheap.

[@mc_cpu]

Good to see the price of this technology coming down. But it would really be just a toy for me so still a bit pricey at the moment.

[@charlesdparker3925]

Try a coat of permanent black marker on the usb shiny surfaces.

[@christopherguy1217]

Nice imager but at over $500 I'll buy direct from FLIR the prices are similar and it's a FLIR so quality and support are in a different league.

[@maicod]

@ 3:26 it was selfie-time eh Julian :)

[@darazs6173]

What the good choice? Reveal PRo or HT-A1?

[@drteeth7054]

I would not anything like those from abroad as I would not want to get hit with duty and not have the protection of the UK consumer laws. Not to mention a local warranty. Luckily, Amazon to the rescue. A very welcome review as a thermal imaging camera is goimg to be my 60th birthday present.

[@bitrage.]

The clicking is the shutter

[@UnexpectedMaker]

Hmm, I think you posted this just to stir me about mentioning I wanted one in my last stream! Wow, that looks nice, but $600 AUD! Ouch!

[@JulianIlett]

Ha, yes, I remember that!

[@muppetpaster]

Sensors do about 50/60 dollar

[@nflores5433]

toroidal fields are interesting right? maybe it's just me

[@Freeqwer]

Hi . Modernization of the thermal imager HT-A1 to determine damage to electronics : kzbin.info/www/bejne/pYGrpYKposqCedU On firmware 2.1.13 there is a function to adjust the thermal image relative to the image from the visible spectrum camera.

[@JulianIlett]

Thanks for the info :)

[@markflack9191]

How much is it?

[@JulianIlett]

Not sure yet - waiting for my contact at Banggood - I think they're on holiday in China :)

Better add a hundred more and get a seek pro.

[@kyoudaiken]

For me, the LCD looks damaged in shipment.

[@atmel9077]

Those cheap LCD displays always leak light at the edges of the screen. Usually they're glued/clipped to a bezel which hides that, but here the LCD is rather glued to a PCB, and it's too far away from the glass.

[@macro820]

Is parallax better in portrait mode?

[@JulianIlett]

No better - just in the other axis :)

[@bridgendesar]

Take the camera outside and see who's growin da weed! On a more serious note, would you consider donate a unit to the local fire brigade?

[@vaguedirector_7342]

I have both the 60x60 HT-02 (~$250aud) and the 80x60 FLIR One Gen 3 (~$400aud). The HT-02 is absolute trash in comparison, even though the sensor is supposed to be a similar resolution. It's night and day. DO NOT BUY THE HT-02, it's barely usable. Get a decent one from FLIR or Seek, they're not that much more expensive. Edit: Image Comparison, both pointed at my computer (imgur.com/a/5WeqxPD ).

[@ledhunters]

I learned new UK english word today: bluuuuurr and bluuuuurrinesss. It's a bit strange but hey, it's UK, they drive on the oposite side of the road ... :P

[@alankingvideo]

Not going to try and breathe life back into the dead Julian’s Reviews channel then?

[@davidmartin1628]

A KZbinr called "voltNik" modded his HT-02 by installing an buck-booster; a rechargeable lithium cell and an USB lithium cell charger. A £1 buck booster is sufficient on its own to avoid the low voltage problem.

[@electronic7979]

Very nice item

[@ParedCheese]

Product links? 🤔

[@MrPenguin098]

Great video. Nice product. But, will it tell me if my holiday turkey is properly cooked, lol.

[@DmitryEljuseev]

Thanks for the review. Seek Thermal looks better for this price, and have higher resolution and adjustable focus. For this sort of banggood stuff normal price is 50-100$, not more :)

[@FindLiberty]

Nice

[@JAKOB1977]

hmm perhaps a tad to expensive for 30k resolution at 410 USD bucks + import VAT. One thing you really gonna miss is the adjustable focus and high resolution, and If you make video's then a useable relative high fps is a must at 'least higher then the norm of 8fps. Have recently purchased a thermal camera myself and had to pay a little under 300 USD from US and too here in pricey Scandinavia but I gotta admit I have really been happy about that purchase. Its a fast Frame edition so higher then 8fps legislation I'm usually averaging a little under 20fps and a resolution at 320x240 and 78k heatpoints with a microbolometer in the spectral range of 7.5 to 14 microns and it also got adjustable focus. I love that I can see resistors heating up in makroshots (look at 2.51 and you can really sense the metalcurrentplate underneath but can also use it down the street and in the bigger perspective like some of the videos show..- kzbin.info/www/bejne/sHfWm4aObadjo6c But yeah the new one A1 is way more usefull then the first, you got send from BG Julien.. thx for the vid..

[@whitefordpipeshandmadebymi7238]

Wow 550.00 Canadian guess I won’t be buying one ! Sucks being on a disability pension! Take care! Peace ✌️ from Welland Ontario Canada 🇨🇦

[@Mark1024MAK]

WHITEFORD PIPES HANDMADE By Michael David - Don’t feel bad. I could afford one, but don’t see any real need. It would just be another expensive toy. If you are designing your own circuits, it’s not hard to work out if your circuit sections/components will be operating within the manufacturers temperature specifications. The only time that I can see a real use for these IR cameras, is in industrial system fault finding, where the cost is nothing compared to the down time costs. For hobby use, either use one of the cheap DIY sensors, your finger, or a meter with a temperature probe (or equivalent).

[@trottx]

I'll use my middle finger like Julian does.

[@nielsdaemen]

It's now 386 euro's! You can get something way better for that price!

[@Hugo-py2ce]

Wow that handheld one sucks really bad.

Pretty cheap but crap resolution and stuttering af! The Seek cameras still beat the crap out anything else in the civil sector. It is odd that the evolution of thermal iamagers looks like going backwards. Instead of having better, higher performance devices available on the market, thrse get shittier by the day.

[@anlumo1]

Similarly to encryption in the 90s, they get a lot of issues from weapons export laws.

[@robertrobhog]

$410 someones having a laugh

[@borayurt66]

$410... I'll go for Flir with that price.

[@greg4795]

what are you going to get at that price from FLIR ... a carrying case?

[@BenMitro]

Julian, when you purchase a high priced item from banggood and it doesn't arrive, in my experience, all their great service goes out the door. I ordered some phones, they didn't arrive and then banggood started asking for more and more proof - first the local post office, next local customs....they just don't stop until you give up. In my case, over $700 evaporated. I will NEVER buy from Banggood again.

[@jespercarlsson9239]

Look at 13:27,and listen...

[@alien8r33d]

Looks useful, yet at the same time, bloody cheap and nasty. Save up for a Flir or Fluke.
