Steps:

  1. Choose a Security Camera App:

    • Download a security camera app on your old smartphone. Some popular options include:

      • Alfred: Free, user-friendly, and works on both Android and iOS.

      • Manything: Great for cloud storage and motion detection.

      • IP Webcam: Offers advanced features like streaming to a browser.

  2. Set Up the App:

    • Install the app on both your old smartphone (the "camera") and your current smartphone or tablet (the "viewer").

    • Follow the app’s setup instructions to connect the old phone to your Wi-Fi network.

    • Position the old phone where you want to monitor (e.g., front door, living room, or baby’s room).

  3. Mount the Phone:

    • Use a tripod, suction cup, or DIY mount to secure the phone in place. For a DIY mount, you can repurpose items like a binder clip, cardboard, or a phone case glued to a surface.

  4. Power the Phone:

    • Plug the old phone into a wall adapter or connect it to a power bank to ensure it stays powered 24/7.

  5. Configure Motion Detection and Alerts:

    • Enable motion detection in the app to receive alerts on your current phone when movement is detected.

    • Adjust sensitivity settings to avoid false alarms.

  6. Optional: Add Cloud Storage or Local Storage:

    • Some apps offer cloud storage for recorded footage (may require a subscription).

    • Alternatively, use the old phone’s internal storage or an SD card to save recordings locally.

  7. Test the System:

    • Walk around the monitored area to ensure the app detects motion and sends alerts.

    • Check the video feed on your current phone to confirm the camera angle and quality.
