how far can you see using IR at night? in yards?

haven't tried real distends yet but looking around you can see preety far as a messure i dont no

75-100 yards, more or less. You're not going to get much resolution after 40 yards or so. My numbers are rough, novice, estimates, though.

with the included light, about 20, not clearly, if you get a more high power light you would see more

Brian, just measured distance of infrared at night. I get a distance of 45' do not have any leaves or tree limbs in the way of night vision as this will decrease the distance. Do some more research on a better camera, hope this helps.

From my research, you can, but to use at night the IR will reflect. To get around that you'd have to turn off the IR and also potentially cover with black tape. Then use a LED illuminator like this: http://tinyurl.com/qz457ac

If you look directly into the device, there will be a faint res dot. You can not see any light otherwise. It will throw out to about 150 yards effectively, maybe a bit more. There ia about a 30 degree angle either side od center.

I don't know how to determine the field of vision in terms of feet or yards. My impression was that I saw what I expected, both in range and detail. In fact, I was pleased with the range and the details when I first tried it. It took me a few minutes to get my bearings because this is the first night vision device I've tried. Perhaps to put it in perspective, I stood on my back deck and looked into the approx. 2.5 ft wide by 4 ft high window on my shed which is about 20 yards away--I could a rope inside the shed, window panes, and other objects inside the shed. So, at about 12 to 15 yards I could just see the 2.5' by 4' window missing (blocking out) only a few inches on the height.I hope this helps.

A naked eye cannot see IR lite. Only if someone is wearing or using night vision device will be able to see the IR ligby emitted. This scope can be used with or without the IR light. Nights with ambient light from moon and stars it is possible to use scope without the IR light.

At night, with the infra-red lights, the cameras simply show reflected light. If the camera is pointed at empty space (not pointed at trees, grass, or other objects), the night time picture will be entirely black. The infra-red lights seem to project out roughly 50 feet - of course at that distance at night it will be difficult to pick out many details about the object that is recorded. If there is ambient lighting (street lights, overhead security light, infra-red light provided by other cameras or external IR emitter) it is possible to extend the night time visible area.

Yeah, we have some Speco cams that have invisible IR lights. So they are not visible at night. It seems the invisible IR lights are getting harder and harder to find these days.

I purchased this primarily to use on my home defense weapon. I want to see what I'm shooting. Because many of my usage scenarios are inside, I actually went outside in the sunlight to check the range. There is a big difference when you are in the sunlight, but I could see it roughly 30 - 40 yards away.

Depends on what yardage you have it sighted in. Typically sight it in at 100 yards and go from there.

I've gone out at night with it and I can see the green dot as far as I am able to see due to obstructions in the area. I guess it was about 200 yards. Of course the dot is easier to see if you're not in direct sunlight but you are still able to pick it up looking through the scope.

This camera uses infrared LEDs to provide night vision in total darkness up to 30ft. If the camera is pointed towards a window, the infrared will reflect off the glass and affect the picture quality. This type of installation is not recommended.

I'm not sure about any restrictions that might result from operating the system in China (possibly access to the cloud-based storage of video?), but I do know that the cameras use infrared for night time use. It seems to be fairly effective out to about 20 - 25 feet.

This device will give you visible range of about 150-300 yards. You can drive but need to be careful as if you are going fast you may not recognize certain obstacles in time.

no "flash", it's infra red....not visible to human eye. Picture looks like a flash was used. Distance is therefore limited. I'd say 50 feet at night, for well lit picture.

I can see almost 100 yards clearly, if there is total darkness. If there are other lights off to the sides it makes it more difficult.

No. not at all. Even if u put in outdoor case ir stills reflects back. Night vision diminishes. If u want an outdoor get an outdoor
