It does work at night, although there are a few momentary false positives. So if you've got an itchy trigger finger, you might want to reconsider 😉

As far as range, it's hard to tell. Based on my limited understanding of the underlying tech, it has something to do with contrast. When it senses an object emitting a higher infrared signature than the background, it reads positive. It might be at 5 yards, or fifty yards. It all depends on the contrast with repect to the background. So if it's a hot summer night, and you're running around blasting each other in the dark, it might not work optimally. But on a fall evening, with minimal lighting, this thing's totally got your number.

Sorry I can't be more specific. I'll keep an eye on it over the coming months and let you know how it performs.
