How to Turn Your Old Smartphone into a Budget-Friendly Smart Dash Cam

How to Turn Your Old Smartphone into a Budget-Friendly Smart Dash Cam
Dash cams are gaining popularity for recording road trips, capturing scenic routes, and providing crucial footage in case of accidents or insurance disputes. However, buying a dedicated dash cam can be expensive. Fortunately, you can repurpose an old smartphone into a fully functional dash cam with minimal cost and effort. Here’s how to do it.
Steps to Convert Your Smartphone into a Dash Cam

1. Download a Dash Cam App
Choose a reliable dash cam app like Droid Dashcam or AutoBoy Dash Cam that offers features such as:
- Timestamp and GPS tracking
- Loop recording to manage storage efficiently
- Vehicle speed tracking
- Automatic recording when driving begins
Many apps allow background recording, so you can still take calls or use other phone functions.
2. Get a Sturdy Phone Mount
A stable mount is essential for clear, steady recordings. Look for a mount that:
- Provides adjustable angles for the best road view
- Fits your car’s dashboard or windshield securely
- Is compatible with your phone size
Affordable options are available online or at local stores.
3. Use a Charging Cable
Continuous recording can drain your phone’s battery quickly. A long, durable charging cable will:
- Provide consistent power
- Support fast charging
- Keep the setup clutter-free
4. Set Up the Dash Cam in Your Car
Once you have the app and mount ready:
- Attach the mount to your dashboard or windshield.
- Secure your phone in the mount.
- Plug in the charging cable.
- Open the dash cam app and configure the settings (e.g., resolution, loop duration).
Your DIY dash cam is now ready to go!
Essential Items You’ll Need
- An old smartphone (or your current one, if feasible)
- A dash cam app (such as Droid Dashcam or AutoBoy Dash Cam)
- A secure phone mount
- A charging cable to prevent battery drain
Bonus Tips to Improve Your Dash Cam Setup
Use a MicroSD Card: If your phone has expandable storage, a high-capacity SD card can help prevent space issues.
Add a Polarized Filter: A clip-on filter can reduce glare from the windshield, improving video quality.
Keep the Lens Clean: Regularly wipe your phone’s camera lens for clearer footage.
Protect Against Heat: Cars can get extremely hot; use a heat-resistant case or remove the phone when not in use.
