I have mentioned in my other post that my grandma is a dementia patient. Now she started moving out of the house carelessly. It is a busy road in front of our house. So the chances of an accident are more if she steps into the road. It is not practically possible for us to be around her all the time. So in order to avoid the chances of an accident, we are planning for security alarm installation with deadbolt locks. I don't know how effective this will be. But hoping for the best. If you have any other ideas on how to make my grandma secured at home, do share it.
