MR60FDA2 60GHZ mmWave Sensor takes a long time to detect Fall Status

I’m trying to use this device in the bathroom of an asylum as a contribution to the safety of the elderly individuals, I wanna know how these variables (rect_XL , rect_XR, rect_ZF, rect_ZB) are set and how they interfire in the ps rocess.
Thee height is 2.3 m, sensitivity is 6 and threshold is 1.
The values get from the radar for the variables are all 0.3.
Best reggards,
Eduardo
