Hi everyone,
Thanks for having me!
Do any of the FLIR alternatives e.g. hikmicro, have the ability to lock scale.
I would like to bring one into my job, to find drafts and leaks when insulating homes.
I understand locking the scale is a characteristic I need. And wondered if anyone could help. I do know the FLIR pro has this capability, but wondered if any others do

I have the TC003 (android tablet) so probably similar to TC001. It does lock the scale, although what it does is it greys outs things which are outside the scale. It's not what I expected it to do, I would rather it have locked the calibration at certain temperatures.
Recorded this on my TC003, although the video quality seems pretty bad it shows the issue i mentioned (the online OneDrive player doesn't seem to load the video for me, but you can download it and it seems to work fine) - https://onedrive.live.com/?authkey=undefined&cid=03B7AF34263E73B8&id=3B7AF34263E73B8%2156141&parId=3B7AF34263E73B8%2156140&o=OneUp

I assume that what you want is more commonly known as manual level and span. IE: the ability to manually set the lowest and highest temperatures of the false-colour palette so that a given temperature within that range will always be a certain colour as you pan across or compare various scenes. As opposed to the instrument auto-ranging based on the highest and lowest temperatures of the current image.
Among some of the most commonly considered budget stand-alone IR imager options, my recent research revealed:
The Hikmicro B20 and Guide PC210/230 offer manual level and span capability.
The Uni-T UTI260B/690B, Infiray C200, Hti HT18/18+/19 Vevor TC240N and Topdon TC004/TC005 do not.
I personally ended up buying the Guide PC210 and have been quite happy with it thus far. The Hikmicro B20 is also highly thought of by owners. It has a larger display screen with slightly better sensitivity, but is 2-1/2 times the price and has a much shorter battery life. Other than that, the specs are very similar.

Talking about Cell Phone Thermal Imaging for Hunting, after a solid decade in the wilderness, I can assure you that the FLIR Scout TK surpasses both the Xinfrared T2 Pro and the AGM in its performance. If you're seeking a better value, the Xinfrared T2 Pro might be your pick.

I would say p2pro is probably a good choice, it's pretty cheap and has good performance. While there is a problem that I can't successfully record video. When I hit record video, everything looks fine on my phone, but then when I go to view it later there's no video. I am trying to figure it out...

P2 is a dongle format connected to your phone.
You need a dedicated phone w/ a "hand fix" for p2 to run it comfortely cause dongles can disconnect time to time & fall down. Also battery lifetime is much better on handheld dedicated cameras as is.
Just my 2 cents, after using a handheld TIC i don't want to use dongles anymore.

I'd like to ask for your guidance. I'm looking for a (low cost) thermal camera for strictly unscientifc filmmaking purposes. My budget tops out around $400. I want at least 25hz, and I'd like to be able to turn off all measurement, crosshair and pinpoint features. Ideally, I'd like to be able to manually adjust the exposure, or at the very least lock the autoexposure. The less often the device freezes me out to do autocalibration the better. Having a fusion camera function is nice but not a dealbreaker. I'm looking for the highest thermal image quality in my budget which allows for the longest possible smooth shots without freezing. And manual exposure would be great. With all these things in mind, I've been looking at the Doogee V20 pro, the Infiray T2s+, P2 Pro, and XH09, Tooltop T7, and now the Guide PC210. Does any one of these models, or any other model, stand out as well suited to my purpose? Thanks!

The Hikmicro had a manual span feature, but it would revert to auto span every time I turned it on, so I had to set the upper and lower limits every time I started it up.
