Why Reuse an Old Smartphone as a Security Camera?

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.
