Due to the radar installation height and the radar beam range, the maximum
distance for body movement detection in this installation mode is L3 ≈
6.5m; the maximum distance for body sitting/ movement detection is L2 ≈
3m and the maximum distance for body sleep detection is L1 ≈ 1.8m.

Caution.
A. The above-mentioned different installation methods require the radar
main beam to cover the main human activity area and to be orthogonal to
the normal direction as far as possible.
B. When installed diagonally downwards, the horizontal distance will be
reduced due to changes in the horizontal projection of the coverage area.
C. When the module is in operation, the surface of the module should not be
obstructed by metal objects.
