What is the best location to connect the power supply for a dash cam?
1 Answers
A dash cam's power supply is typically connected to the cigarette lighter socket, as this method is the simplest and most convenient. Dash cams generally come with both built-in and external power supply interfaces. The built-in power source is usually a lithium battery, while the external power source is typically supplied through the cigarette lighter. The capacity of the built-in battery is very small, providing power for about an hour, whereas the external power supply is more convenient and can last for a longer duration. A dash cam is an instrument that records images, sounds, and related information during vehicle travel. Once installed, it can record the entire driving process, including video and audio, which can serve as evidence in traffic accidents. It's important to note that the video footage from a dash cam should not be edited, as edited footage cannot provide assistance in the event of a liability accident. The dash cam can be directly plugged into the cigarette lighter. Once powered, the wiring can be routed through the storage compartment, A-pillar, and other areas. However, this method occupies the cigarette lighter socket, and since the wiring in the storage compartment cannot be hidden, a portion of the wiring will remain exposed. The advantage of this method is that the dash cam can be manually turned on or off by simply unplugging the cigarette lighter or pressing the switch.
