You can monitor an older adult at their home using security systems that feature remote smartphone access. By installing the system’s companion app on your phone, you can monitor the security system in your loved one’s home and be the first to know when there are emergencies. You can even use the app to arm or disarm their security system remotely. You can also use security cameras that stream to smartphones, but be sure to check with your loved one before installing one in their home. They might see the cameras as privacy intrusions.
