How to Turn an Old Phone into a Dash Cam?
2 Answers
In the old phone, download a dash cam app, then use a car mount to fix it in place, connect it to the cigarette lighter power source, and it's ready to use. It offers powerful features, supporting loop recording and automatic recording when powered on, making it not much different from a dedicated dash cam.
Turning an old smartphone into a dash cam is quite easy to get started. First, download a free dash cam app like Nexar or DailyRoads Voyager, which support HD recording and automatic loop recording to avoid storage-related lag. Mount the phone on the top-left corner of the windshield using a strong suction cup holder to ensure an unobstructed view and prevent it from falling while driving. Then, connect it to a car charger for power, plugging the USB cable into the cigarette lighter port to maintain stable battery levels. Set the app to start recording automatically and check that the resolution is set to 1080p or higher. If you're concerned about the phone overheating in summer, try adding a heat sink to the mount or placing it in a well-ventilated spot to reduce risks. The benefits include saving money and hassle, giving old devices a second life, with video quality that rivals professional gear, plus the ability to review road conditions anytime. If storage runs low, just add a microSD card—even beginners can set it up in 10 minutes, and regular app updates are all that's needed.
