  1. I tried using my old iPhone as a security camera with the Alfred app. Setup was super easy, and the video quality is surprisingly good! I placed it near my front door to monitor deliveries. Just a heads up—make sure to keep it plugged in; the battery drains quickly when streaming continuously. Overall, it’s a great way to repurpose an old device!
