Those are just not meant for what you want to do. There for close range only. If you look at the charts you'll see that theres a honey spot and even if you make the led brighter or amply the output you'll not gain anything really.
You'll make it pickup say 3 feet objects but you can't tell if its one and half foot or 3.
The chart shows a peak at a little over 2 mm but 1 mm and 5 mm are the same.
So you just change the honey spot.
To give a range would be very hard to do.
