If the “Delay Fall Alert” is OFF (default value), an alarm will be sent immediately when a fall is detected.
This is useful for demo or test purpose and is not recommended for practical use.
The change of “Delay Fall Alert” will restart the device to make it effective.
4.2.15 Hand Waving Detection and Sensitivity
“Hand Waving Sensitivity” is a toggle switch to turn on or off the hand waving detection feature, and
select the hand waving sensitivity. When it is turned off, the hand waving detection will be disabled.
When the hand waving detection is enabled, a person can wave to the sensor to actively ask for help.
The face of the person must be detected by the sensor before an alert is sent out.
Three hand waving sensitivities can be selected: Low, Med, or High. The default value is Low. In this
case, to trigger the hand waving alert, the person needs to face the sensor and constantly wave his/her
hand for about 8 seconds, and the upper arm should be raised at least to the shoulder height. After
detecting a waving hand, the LED of the sensor will first blink red for about 5 seconds. If the hand is
waving in most of time during this period, the LED will turn to purple. After the LED becomes purple, an
alert will be generated to signal that someone is seeking help.
Changing the sensitivity to Med or High will increase the sensitivity, and the person will only need to
wave about 5 seconds to generate the alert. In addition, when the sensitivity is High, the upper arm
does not need to be raised to shoulder height.
Note that increasing the sensitivity also increase the chance of false alarm, which can be managed via
the Manage False Alert page in Sec. 6.
After a waving hand alert is generated, the sensor will not send the same alert in the next 15 seconds.
