Can you see breathing at night? can you see the hot air escaping from the person?

No, the IR is not sensitive enough to detect a thermal plume like an exhalation. For that kind of system, you are in the $1000+ range.

This is purely low light. It works by displaying images in high contrast, though it also has red leds to "illuminate" things are a longer range, which is barely visible.Despite it's "infrared" claim, it has _no_ infrared capabilities. I've tested it with an electric stovetop, producing a very high temperature gradient with no light in the visible range, and there was absolutely no difference in the view from the hot top to the cold ones.It does work really well for low light.

No, you can not see hot air coming from a person, or at least I didn't notice that. In a completely dark room when you can't even see your hand in front of your face, you can see a person and identify who they are. This is a very cool toy, although be careful with them because they break easily.

No..you cannot see a persons breath. this is a childs toy and not much more.

Yes you can. These night vision infrared stealth binoculars are lots of fun, my boyfriend used them for deer hunting and said the were cool. But their not high quility, they are a toy. Don't expect too much from them. Have fun!

No. This is a night vision goggle style-NVG (green illuminated picture). Not a thermal style that shows heat.

The ir flash can not be seen at all. The subject is illuminated but they will not know their picture is being taken. Night time pictures will be black and white you will not be able to determine the color of clothing or hair but if you will know when they were there and how many there are.

No, you cannot see through it at night. You roll the covers down to let in light and then roll them back up at night from the outside. They have Velcro to hold them in place.

My unit is not in the bedroom so I don't really know if there is an emission of light at night. However, I can't imagin any source of light other than the little indicator lights for fan speed and desired level of humidity.

I haven't tried it outside at night, but you would obviously be seen. You would probably see the ground clearly enough.

You won't be ale to breathe or see. I cut a 4inch square hole in the neck for extra air just to give a ten minute speech speech in a crowded room . I was still sweating when I took it off. Visibility is also very limited just standing still.Running and you will see nothing since you are looking out of the small mouth that will be bouncing up and down.Other than that, have a ball.Do you have someone with a seeing eye dog mask that could lead you?

No. It's a foggy but anyone from the outside is only able to see a Silhouette.

Yes, but the readings will be all over the place, as it reads temp at the surface not below. You have different amounts of blood flow and also evaporation to deal with.

You can see out at night though slightly darker. The film reflects so that it is harder to see in during the day however that is also dependednt on the amount of light inside the house.

I purchased this for my son and his wife. I forwarded your question to him and he said, "Yes, you can still see the temperature."
1425265
Yes. You can hardly notice it. Would be fine for running at night while sleeping.

Hi, barely noticeable. Sometimes I think it is not working, so I put a finger to feel the air coming out!
1919139
Yes, I have tried. DO NOT do this, they are not even noticable at night time. Very dangerous.

I think the more important question is, when someone from the outside looks into it, can they see the light change to dark when you look into it from the inside of the house? Basically, can the person on the outside tell if you look into it from the inside?

It works as far as breathing goes. You won't struggle for air, but it isn't made to work like a genuine respirator.

I haven't had a problem with any light coming through. I tend to be pretty sensitive to the tiniest amount of light when sleeping and haven't had any issues with the mask.

There are two sources of light. The nightlight can be turned off but the power light on the top cannot. It actually is quite bright and I found it annoying. I have resorted to putting a wash clother over the controls at night. The wash clothe is small enough that it does not restrict the air flow but if the rotating feature is on, I suppose it could knock it off. I suppose a loose piece of masking tape might work. Have not had to try that as don't use the rotating feature.
