And additional 111.06€ for Tax, Import Fee, DHL Import,...  :-- Sometime I win sometime the Gov...

Here some Images: (Please know I adjust the size by 2x.)

Looks to be working OK. That appears to be the imagery of the standard Seek Pro J3-603-320 OEM core.

Check the temperature measurement accuracy...... it is an area that can be an issue with the J3-603 core.

Hi
I forgotten to mention that the Cam have an replaceable Accu to. The is in the Handle. The "only" Downside is the use some special Connector and maybe is not that easy to get.
I just use them as expensive Toy. How should I measure it?

Basic thermal camera measurement accuracy tests.....

Set the Emissivity to 0.96 for Ice water and Ambient water

Measure water with lots of melting ice in it. Result should be close to 0C
Measure boiling water in a pan or kettle. Result should be close to 100C
Measure a non reflective surface with a thermometer and then measure it with the camera. Compare results. Emissivity does need to be considered for the imaged surface.

Hello. Excuse my bad english.
in my country I cannot find the answer to my question. I have an Hti-HT19 and Hti HT-A2 thermal imager.
Very good appliances. But I miss setting the temperature range. For example, from + 5 to + 15C.
Is there a possibility of a new firmware of the device?

 :-+ I dont see any Updates. I dont know if its possible for us "end user" to do so.
Maybe there are some hidden Pins unprotected against a Hack.

I got the Hti HT-A2 and I recommend it to anyone who can afford it!

I managed to ask the seller on aliexpress to do a 50$ invoice => No import fees  :)

My version of firmware is 2.1.8

I don't recommend the HTI-A2
I have an HTI-A2 and also own a few FLIR and Hikkvision thermal cameras.
The Hikvision DS-2TD2136 is a cctv module which i used with the built in adjustable focus lens (if you open it up) as an electronics camera, an absolute beast at 50Hz refresh rate 384*288 resolution and very good sensitivity, never seen anything like that, but anyways...
The HTI-A2 is basically a Seek Pro core, so pretty noisy and thermal sensitivity isn't great
Also it only saves JPEG , not radiometric JPEG, just standard jpeg as a full screenshot where you also see the battery level, emisivity, everything that was on screen when the image was taken.
Now for the painful part: HTI don't EVER reply to your emails after you bought the product, EVER.
I left a 1 star review for their product/service and that was never added to their official reviews page on their site, pretty crooked if you ask me, i did that twice, "thanks for your review" message, days and weeks later no review was published.
Don't ever think about customer support or firmware upgrades for their products.
You buy cheap because it is cheap as an overall experience ! (compared with other cameras of same resolution offcourse, not that it's cheap by any means)

Servus
I like mine its good (enough) for Home and "light" Office use. I can see where some Chips,... are faulty. In comparission with other Brands I can order truth my IT Distributor mine was WAY cheaper from Ali Express.

I might be able to get a Hikvision DS-2TD2136-15 for a good price. Are they easy to setup as a PCB inspection camera? Or is there a lot of DIY stuff to do first? If you could share some details about your setup I would really appreciate it.

I am OK with opening it and adjusting the lens, but I don't really know much about programming, if that is needed. sorry if it's somewhat off-topic, but I haven't been able to find a post with that kind of use for such camera.
