Why Reuse an Old Smartphone as a Security Camera?

Instead of dropping $100–$300 on a new surveillance system, why not just repurpose a gadget you already own? You're saving money, avoiding subscriptions, and still protecting your home.

Eco-Friendly and Sustainable

Giving your old smartphone a new life is a win for the planet. It's a sustainable practice that reduces e-waste and conserves resources. That’s a tech-savvy and eco-conscious move.

Easy Setup with Modern Apps

Thanks to today’s free apps, setting up your phone as a camera takes less than 15 minutes. You don't need to be a tech wizard—just follow a few simple steps, and you're good to go.

What You Need to Get Started

An Old Smartphone

Any Android or iPhone device from the last 6–8 years should work fine. Make sure it still connects to Wi-Fi and has a working camera.

A Stable Wi-Fi Connection

This is crucial. Your DIY camera will stream or record footage via Wi-Fi, so a steady connection ensures smooth performance.

A Phone Stand or Wall Mount

You’ll need to place your phone in a strategic location. Use a small tripod, a wall holder, or even get creative with sticky mounts.
