For the LD2412 radar module, when the distance gate resolution is 0.2m, the detection range is 0-2.6m; when the distance gate resolution is 0.5m, the detection range is 0-6.5m; and when the distance gate resolution is 0.75m, the detection range is 0-9m.
The LD2412 module has a total of 13 distance gates, with distance gate resolutions of 0.2m, 0.5m, and 0.75m. The smaller the distance gate resolution, the smaller the detection range but the higher the detection accuracy.

FAQ
LD2412 Ground Detection Distance:
LD2412 behaves differently from LD2410 in ground detection. It will automatically adjust its parameters after calibration, but it will not modify the ground distance value. This distance cannot be viewed from the app or an upper computer system.
Constant Restart After Powering On:
This issue is often caused by low voltage and can be resolved by switching the power source.
Motion Detection Behind the Module:
LD2412 can detect motion behind the module, but LD2410 does not due to a possible shielding effect. Ceiling-mounted installations may experience interference due to the thickness of the ceiling.
Different Detection Ranges for Ceiling and Wall Mounting:
This is due to the design of the radar. The ceiling mount provides a narrower range (90° and 270°), while the wall mount covers a wider area (0° and 180°).
LD2412 Bug in Stationary Detection:
A recent firmware update(V1.24.24080517) has fixed occasional stationary detection issues caused by environmental factors.
