2) Hold Time
When no one is detected, the relay will be disconnected after the "Hold
time" elapses. Only Big motion can be detected if the "hold time" is set
to "5s", no breathing detection function. Presence sensing (Minor motion
and Breathing ) can be realized if the "hold time" is set to "30s" or
longer. In order to ensure the detection effect, please set the "hold time"
to "1min" or longer if it is a single-person space. At the same time, the
"hold time" is not recommended to be set to more than 5 minutes, so as
to avoid the interference of other motion signals in the detection area.
