SAMi is a patented sleep activity monitor for caregivers and individuals who need to carefully watch for abnormal movements at night. SAMi uses a night vision network camera to look for unusual motion disrupting sleep. When an unusual event is detected an alarm is sounded. The display instantly switches to show video and audio. Within seconds, the caregiver can assess the situation and take any necessary action. Each event is recorded for later review.While the SAMi app can use the iPhone or iPod cameras, it works best with the SAMi network camera available from www.samialert.com.
