The app Alfred can combine two things that are important to your life. First, what to do with your old cell phones, and second, how to improve security inside your home. You can turn your old smartphones into security cameras with this app. It lets you live-stream video from the house. First, you have to put the app on both phones and pair them. You can use it to talk to anyone at the end of the video stream. Your old smartphone has a motion detector that can trigger the video. The app can also be used as a video baby monitor. You can even use both cameras for extra security. You don't need an expensive in-house camera setup for your protection. Just use your old smartphones that are lying around doing nothing. Alfred Home Security Camera is a free app on iTunes and Android. It has in-app purchases
