How far away can the person be from the eye tracker?

The distance suggested by the manufacturer is between 45 and 90 cm. Hope this helps.

you really have to be very close to your targets, so i really don't know how close you can get. sorry i could not be of any help to you

Sorry, forgot to mention that at the viewing distance, you probably need to be around 5 ft from screen for the 30". And about 10ft for the 60".

I was able to track the speed of a car at about 200 feet. The farther away the object is, the less accurate the reading is. And the more objects that are moving in the sight of the gun can also confuse it.

Yes there is a guideline. If used for surveillance it would have to be pretty close to make out the face.

You can focus on objects as close as 1.5 feet. For distance viewing, it brings everything 6-8 times closer depending on which model you get.

Q: How far can you see with this pair of binoculars? A: Minimum distance = 40 feet. Maximum distance = Infinity e.g. you can see the Moon and the stars like the Milky Way etc. Looking at the earths horizon at any given distance you'll see everything 15 times closer. Just bear in mind that everything is seen 15 times closer than what you see with your naked eyes. Thats the key answer to your question.

Hi, I recommend you to check the Optoma website distance calculator. http://www.optomausa.com/support/calculator/

Eye relief is unlimited due to being 1x. Even at indirect view. As long as the dot is on targetUse mine at about 8 inches.

I think they consider 4 feet away to be ideal. You should also note the detector will only work on panel doors (you mount it on the top panel) and not solid one piece doors the swing upwards or carriage style.

Using low magnification the farthest is approx. 1 feet. With high magnifications the nearest is 2-3 inches

Hi there, This sensor features a 60 degree viewing radius from dead center. The field of coverage will increase the farther you are from the sensor (Up to 39 ft.) but the sensor is designed monitor small areas 10 to 20 feet from the sensing eye (so as to minimize false alerts). In other words there is very little peripheral vision the sensor offers.

yes if you get too close. You have to keep your face about 10-12 inches away.

According to the company's specs, your eyes should be 12 inches away from the light source and approximately in the center of the light. Also, the light screen must be tilted at a 15 angle toward you.

Hello as per maker about 35 ft that is true if you have a lot of ambient lighting. You can see about 10-15 ft if you have like a wall or something that would reflect and light up the area. If you approach the line of view of a camera you can see the person but that about 10-15 feet. I install a zmodo ptz camera that has larger and more powerful IR lights and in that one you can see at night real good and when it scan close to the other camera then you can see real good on them too. One solution is to buy IR light to ligh up more the area you want to view or leave some lights on.

About as far as you can still see it with the naked eye...so at least 50-100 yards.

You can set the distance however you like. I had mine set so that someone could accidentally brush up next to my car but if they stuck their hand inside it would go off
