This simple solution is cost-effective and requires no professional installation. Whether you want to keep an eye on your living room, monitor pets, or add extra coverage to your existing system, repurposing a smartphone is an excellent option.
Why Use an Old Smartphone as a Security Camera?
Old smartphones still carry valuable features such as decent cameras, Wi-Fi connectivity, and built-in microphones. By using them as cameras, you can save money compared to purchasing a dedicated security system.
It also allows flexibility in placement. Phones can be positioned in areas where you might not have invested in a permanent camera. For short-term needs, such as monitoring a child’s playroom or checking on pets while away, this is a practical choice.
Step-by-Step Guide to Convert a Smartphone

1. Prepare the Device
Charge the old phone fully and, if possible, perform a factory reset to clear unnecessary files. Since the device will be used continuously, it should remain plugged into power to avoid battery drain.
2. Install a Security Camera App
Several free and paid apps are available that turn smartphones into security cameras. Popular choices include:
- AlfredCamera (iOS and Android) – Provides live streaming, motion detection, and cloud recording.
- AtHome – Offers remote access, two-way communication, and recording options.
- IP Webcam (Android only) – Allows streaming via a web browser or integration with surveillance software.
- Haven (Android) – An open-source option that uses sensors and the camera for intrusion detection.
3. Connect the Camera and Viewer

Install the app on both the old phone (camera) and your current phone (viewer). Set up accounts and link devices using QR codes or logins. Ensure both devices are connected to a strong Wi-Fi network.
4. Position the Phone
Choose a strategic spot for monitoring. Placing the device high in a corner often gives a wider field of view. Secure it with a phone stand, tripod, or wall mount.
5. Keep the Power Supply Stable
Continuous use will drain the battery, so keep the phone plugged into a charger. For backup, a power bank can help during short outages.
6. Configure Settings
Test the live feed, adjust motion detection sensitivity, and enable alerts. This prevents false alarms while ensuring important movements are captured.
7. Regular Maintenance
Check the device periodically to ensure it is working correctly. Restarting the phone occasionally can improve performance.
