The reasons why the dash cam does not start with the car are: 1. Loose power connection; 2. The dash cam is not properly set up; 3. The dash cam is damaged; 4. The dash cam is powered by a battery and is not connected to the vehicle. A dash cam is an instrument that records images, sounds, and other related information during vehicle travel. After installing a dash cam, it can record the entire driving process with video and audio, providing evidence for traffic accidents. For those who enjoy self-driving tours, it can be used to document the process of overcoming challenges and obstacles. It can also be used at home as a DV to capture life's joys or as a home surveillance device or parking monitor.
I've encountered the issue of dash cams not auto-starting several times, and found the most common cause is a loose cigarette lighter plug. Veteran drivers know that over time, the spring contacts in car cigarette lighters loosen, causing power cuts with slight bumps. The power cable is also a hidden danger—mine got pinched by the car door several times, and the copper wires were nearly broken. Additionally, some car models have cigarette lighters in constant power mode, requiring an additional step-down cable connected to the fuse box to enable vehicle-start functionality. Here’s a small tip: check if the dash cam’s battery is dead. Summer heat inside the car is especially damaging to batteries, causing them to fail during cold starts. Recently, while helping a neighbor troubleshoot, I found an even more extreme case: newly installed floor mats were pressing against the OBD interface cable, making the entire vehicle’s electrical system unstable.
