How to turn your old Android phone or iPhone into a security camera - in 4 easy steps

Old smartphones can be repurposed as security cameras using free apps like Alfred Camera, which provides live viewing, motion detection alerts, and two-way audio without subscriptions. Setup involves installing the app on both your current phone and old device, positioning the old phone near Wi-Fi and power sources, and optionally adding mounts for better placement. While dedicated security cameras offer more polish, this solution costs virtually nothing and works anywhere with internet access, making it ideal for temporary monitoring or expanding existing security coverage.
