Some of us like security. Some of us like security in the form of surveillance. If you have some old smart phones collecting dust in your junk/parts drawer...you can use it as a surveillance camera that can be accessed from anywhere if you know some basic networking (port forwarding). Most of us have at least one. Hell, i have 3 or 4 in my bin. You'll need this app - https://play.google.com/store/apps/...amera&pcampaignid=APPU_mR_XU_W5NIufyATjwYDICw Best to do a factory reset first and go from there. Iphone users, i cant help you. I despise Apple.
