Thanks for contacting Intel customer support.
Intel has tested the IR range and that is the reason why it is published that can reach up to 10 m. In the following link you will find the general technical information.
The 10 m measurement is under very ideal conditions of lighting and calibration. The IR range is a very variable specification and will depend completely on the environmental conditions.
Hope this information helps to clarify your questions.
