For Argus PT, can PIR motion trigger email notification without sounding alarm?

wn8668

Hi,All.
I just installed a Argues PT camera.

My Reolink app (ver 4.18.3.3) UI provides the following options:

1) PIR Settings -> Enable (i.e. sound alarm when motion is detected.)
2a) Email -> Enable
2b) Email -> Email Settings (i.e. set up sender and receiver info for email notification.)

My question is can the camera, upon detecting motion, send email notification without sounding alarm?
If yes, what is the setting for such behavior?
Do I have to enable PIR and set audio level to zero?

Thanks in advance.
