Wall Mounted - Hi-Link HLK-LD2420 User Manual

5.2. Wall Mounted

The recommended wall mounting height is 1.5~2 m. For wall mounting, the X-axis of the radar
module (refer to Figure 5-1) points to the horizontal direction, the Y-axis points upward, and the Z-
axis points to the detection area. The maximum motion sensing range of the wall-mounted HLK-
LD2420 radar module in the default configuration is a three-dimensional sector with a radius of 8 m
and an angle of ±45° in the horizontal and pitch directions, as shown in Figure 5-4.
The detection range of this reference solution for a wall mounting height of 1.5 m is shown in Figure 5-5.
