I find this insulting. ATN claims their ATN THOR HD 1x scope can 'detect' out to 600m. This claim's fineprint is that at 600m you get 1 pixel per 1m of height. So, to detect a person at 600m, which ATN says this scope will do, you would have to notice 2 pixels out of 640x480 (307200 pixels)! This same claim for 'detection' is similar on all of their scopes. This seems absurd. You get a whole 8 pixels per meter size for 'recognition' at 280m. So I guess you can recognize it's a human at 280m using 16 pixels height by maybe 2 or 3 pixels width--again, out of 307200 pixels. Seems ridiculous to base distances of detection, etc. on these type of scenarios.

Are you telling me ATN would overstate their products ability and misguide their customers? That’s it I’m selling my ATN gear. Just kidding at 8 Yards it does ok.
LOL, good attitude!
I can't get into those specifics like you, because I'm a rookie and don't understand it that well. But what model Thor are you referring to that is 1x? Is it the 19mm 384 thor?
I only ask because I just sold a Thor, and have two other buddies that have them, and 600m for detection is easy. But if you a referring to that 19mm sight, I have zero experience with that one.

It is not an absurd claim and you can often very easily detect 2 pixels out of the display. As long as the hot object is significantly different in temperature than the objects around it, you can do it with a single pixel. Part of spotting hogs or coyotes in high grass or heavy vegetation, or finding a downed hog often is made on a very tiny initial detection. I do it all the time.
You can't be lazy about all this, but vigilant in your scanning. When I spot a pixel or two that have appeared in my FOV that were not there previously, I will often concentrate on the spot to see what, if anything emerges. One or two pixels may turn into a mouse, rabbit, skunk, coon, coyote, hog or rock. You never know. It is what can turn a goose egg hunt into a success.
I agree with Brian and don’t think that claim as far fetched at all.
I did a test using a standard gallon milk jug full of 105° water when I left the house and set it out on the road and drove away from it as far as I could to test my ability to detect the object using two thermal devices I had with me at the time. My FLIR vue pro 19 mm 640, and my IRD Mark two 35 mm 640.
The flir is mounted inside a go light on the roof of my truck and it’s hooked up to my laptop computer sitting on my dashboard and I use it to navigate with. I was a astounded to discover that I could detect the milk jug to just over 800 yards.
Here is a YouTube video and the actual digital video file created by the FLIR Vue which gives a better detailed image then when I was seeing on my computer display.
For what it’s worth, I could detect the jug with the IRD out to 1200 yards which is as far away as I could drive on that particular test range.

You may have to download the Google Drive file for it to play but it is a little bit of better image than the YouTube video.
I have been told that detection consist of 3.5 pixels. My FLIR with 19 mm lens has a field of view of 32°. At 400 yards I should be down to one pixel yet, I was able to detect the jug at twice that distance as seen in this video.
The intersection in the road that you can see when I pass it is approximately 550 yards away from that jug.
