1. A non-transitory computer readable memory storing instructions for adjusting a camera parameter using a distance of two or more objects in a 3D monitored space, which instructions, when executed by a processor perform a method comprising:
receiving a selection of first and second objects in a 3D monitored space identified in images captured by one or more cameras using a gesture;
using spatial coordinates obtained for the first and second objects, obtaining a calculated distance between the first and second objects calculated for the selection; and
providing, based at least in part upon the calculated distance, an adjusted at least one camera parameter; whereby the adjusted at least one camera parameter enables repeatedly obtaining spatial coordinates for the first and second objects from additional captured images of the first and second objects.
