Are all dash cams tethered to the power outlet?
Not all dash cams are tethered to the power outlet. While many dash cams do require a constant power supply from the car’s 12V outlet, there are some models that come with a built-in battery or can be powered using a USB connection. These types of dash cams offer more flexibility in terms of placement and use.
However, it’s worth noting that even dash cams with built-in batteries may still require periodic recharging, which can be done using a power outlet. Additionally, some dash cams may have a limited battery life, which can range from a few hours to a full day, depending on the model and usage.
What are the benefits of a dash cam being tethered to the power outlet?
One of the main benefits of a dash cam being tethered to the power outlet is that it provides a constant power supply, which ensures that the dash cam is always recording, even when the car is parked.
