I have a very ill husband, heart issues and cancer, and so I decided to have installed door cameras at each of my doors. Now that I have done this, I have purchased an iPhone and so now any movement is recorded, and I can see it on my phone when ever I am at a doctor's office or where ever I am. I have found that the cameras also work great for me to see my husband when he is outdoors in case he should have a fall. I no longer have to continue to go outside to check on him. When I had them installed, I had no idea they would also work as well for my keeping a check on my ill husband. I love these cameras. I just wanted to share this with others, and wondered if others have done this also? So not only do these doorbell cameras work for security when I am home and away, they also keep me from running my legs off to check on my husband who is very active yet with all his medical issues.
