Tech is getting obsolete so fast these days. 2-3 years old smartphone, updated to latest OS, can be slow and unresponsive. You’ve already bought a new shiny toy anyway so what to do with old iPhone? Turn it into a free home security system of course. You just need to install free Manything app and you instantly have a security camera that has more features than $200 worth of specialized security cameras. It will record and stream the video, it automatically starts recording when it senses motion, it can send alerts to your phone, you can even use it as a means of protecting your business. Much better than the low resolution IP webcams.
