Got an old phone collecting dust? Give it a second life.

Instead of letting that unused phone sit in a drawer, why not transform it into a fully functional security camera? With just a few simple steps and the right tools, you can reuse your old smartphone to monitor your home, office, or even while traveling — without spending much (or anything at all).

Why Use an Old Phone as a Security Camera?

Save money – No need to buy a new camera.
Be eco-friendly – Reuse a device that still works.
Portable & flexible – Move it between rooms or take it on the road.

What You’ll Need

1. A working smartphone
Ideally with a functional front or rear camera and Wi-Fi access.

2. A constant power source
Since it will be on 24/7, keep it plugged in.

3. A stand or basic tripod
DIY with household items or buy one for under $10.

4. A security camera app
Free and easy-to-use options are listed below.

How to Set It Up (Step-by-Step)

Step 1: Install the app on your old phone
Choose and install one of the recommended apps.

Step 2: Install the same app on your current phone (or use a browser)
This will be your “control device” for viewing and alerts.

Step 3: Link both devices with the same account
Usually via email, Google, or Facebook login.

Step 4: Position your phone camera
Aim it at entry points, garages, living rooms, or anywhere you’d like. Use a stable mount.

Step 5: Enable motion detection & recording
Turn on notifications so you’re alerted if anything moves.

Extra Security Tips

Use a strong password for the app.
Connect to a secure Wi-Fi network.
Turn off unnecessary phone features to save power.
Don’t leave the phone too exposed or in plain sight.

When It’s Worth Upgrading to a Professional Security Camera

Using your old phone is great for basic or temporary monitoring, but consider investing in a professional camera if you need:

Higher video quality (especially night vision)
Advanced storage and cloud options
Features like pan/tilt or smart home integration

Look into affordable models from brands like Wyze, Blink, Reolink, or Eufy.

Conclusion: A Smart Way to Reuse and Secure

With a little creativity and the right app, your old smartphone can become a reliable home surveillance tool. It’s an eco-friendly, cost-effective way to protect what matters most—without buying new gear.
