Manually Activate Siren Only

Hi thereI recently bought the full starter kit but am trying to find out if there is a way I can change the siren so it is manually activated only?I have an indoor camera that sometimes triggers a motion (there is a big tree outside the window that often casts a shadow). I do not want the alarm to sound but instead send an alert to my phone so I can check manually.In other words, is there a way I can keep all motion notifications on without it sounding the alarm?Thanks
