With more senior citizens choosing to stay in their homes, more high tech devices are coming on the market to help keep them safe.
"We are doing research to find things to keep older adults in their home longer," said Debra Krotish, PhD University of South Carolina School of Medicine.
Here are some of the latest gadgets used to help keep a watchful eye:
One of three people over the age of 65 will fall each year.
A vibration detector or motion detector can be placed on the floor to sense if a person has fallen. Family members or friends can then track the movement or non-movement from their computers without being too intrusive.
"If you put them by the bedside or by the bathroom door, you know that mom has gotten up in the middle of the night," said Krotish.
Research shows 30 percent of nursing home residents go to assisted living facilities because they cannot manage their medication.
But today's pill dispensers have come a long way from the past. A caregiver can load several days' worth of medicine in a machine that then delivers the right amount at the right time.
A blood pressure cuff and scale sends data by Bluetooth to an online system that family members and caregivers can access.
