The only instructions are on the product page online which I had to read before changing settings and installing. It's not clear from this page, it's only indirectly shown on the charts, but motion detection ("detective" online) doesn't work on a lamp that has a bulb above this device. The bulb should be lower. I bought 4 packs and installed 3 on my porch. The two on the outside wall of the house seem to work (bulb down) but the one under the eaves (bulb up) doesn't work unless you wave your hand next to it. All are set to maximum brightness and maximum delay before turning off. Of the two on the outside wall, the one that works well will turn on even during the day if it detects movement. The other also needs a hand gesture to turn it on (as expected, only at night). So none of them are fully functional, but one works well enough to be useful. My 2 star rating is equivalent to a B in school, barely a passing grade. If I had to do it again, knowing what I know now, I honestly don't know if I would buy it.
