Safe Alert Monitor (S.A.M.) uses motion and presence detection to provide critical alerts for:
Safety: Two people approaching the same door are both alerted to each other by S.A.M.’s motion detection, intelligent processing, light and audio alert
Security: With security mode switch on only the interior unit provides alerts. The exterior unit is monitoring for presence but only alerts you.
Motion Detection: Sensitive passive infrared sensor plus 20’+ wireless communication range, can be easily removed from door mount and set on any flat surface.
