Question 1

Would this pick up an animal outside in the pitch black?

Accepted Answer

This is a thermal sensor so it doesn't use light, it uses thermal energy.  It's a fine little 'thermal imager' and doesn't have a low-light camera like a more expensive 'thermal camera', so all you see is temperature differences.  It's also a low-resolution sensor and has a narrow field of view.  It works best for things that are near by, like a fuse box, pizza oven, or pan on a stove, and it will show an infected spot on a dog's back.  If there's a temperature difference between the animal and surroundings and the animal was large enough I think you'd see it, but if it was more than ten or twenty yards away a small animal would only show up as a few pixels and might not be useful.  The thermal sensor on my drone is high resolution and will spot an animal in the woods from a couple hundred feet up, but it's a $3000 sensor made to be used from a distance, and it also has a low-light camera that makes it easier to interpret the thermal image.  This little TI250 is good value at $300, and it might show a warm animal on a cold night.  Mine will show my dogs, one is a ten pound minpin, in the dark inside the fence just fine, but that's less than 50 or 60 feet out.  Sorry I can't answer for sure, but that's my experience.  I think one of the higher resolution thermal cameras would be better for hunting or spotting animals at any distance in the dark.  IR cameras depend on using a 'bright' IR illuminator that will spook some animals and has limited range, so thermal is the way to go.  I'd be looking for something with a 320 or 640 pixel sensor and a low light camera to do that, one of the handheld units that similar to the thermal sensor on my drone.  It's seldom pitch dark, and starlight or the glow off of clouds is usually enough so that the low light or 'night vision' camera is useful.

Question 2

Are the batteries replaceable?

Accepted Answer

No. And sadly the chemistry of the batteries only last a couple of years. This is a common problem with many new devices.

Question 3

Will this pick up pipes and electrical circuits through regular dry wall ?  What about horse hair plaster walls?

Accepted Answer

if the pipe is really hot depends on how well insulated that wall is

Question 4

What range can it detect. How many feet in distance?

Accepted Answer

It works best within 20'
