Can I install at 10 feet high.

Hey @aed2169. While we recommend installing the device around 9 feet high, since it would be just a foot higher, you shouldn’t see too much of a lose of function on the device. It may not be able to pick up the motion detection the closer it is to the device since it will be a foot higher, but for installing help on where to position it, please check out this Help Center Article here!
