How to Turn an Old Phone into a Dash Cam?
3 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.
Turning an old phone into a dash cam is cost-effective and practical. Download a simple and user-friendly dash cam app like AutoCam or RoadRec, install it, and set up basic options for loop recording. Secure the phone with an inexpensive magnetic or suction cup mount on the windshield, adjusting the position to ensure it doesn’t obstruct the view. Always use a car charger for power, plugging in the USB cable to avoid mid-drive shutdowns. Set the resolution to 1080p for clear footage. The entire process costs almost nothing, repurposing an idle phone and saving money on new equipment. Add a microSD card to expand storage when space runs low. Be cautious of high summer temperatures causing the phone to overheat—leave a ventilation gap when mounting or turn off recording when parked to save power. The process is quick and efficient, automatically recording footage while driving for easy accident review, all while avoiding waste.
