  • Page 15 Parameters Description The ability of radar to detect and identify target. High: Select when there are fewer interfering objects in the detection space and accurate detection of smaller or more distant targets is Sensitivity required. Low: Select to reduce false alarms when there are more interfering objects in the detection space or when the environment is more complex.
  • Page 16 Fall Confirmation Time: When the device detects the target falling and this condition persists for the specified duration, it will judge this to be a fall event. Default: 50s, Range: 0~300s. Note: It is recommended to set the confirmation time between 30s~60s, as setting it below the time may reduce detection accuracy.
