Yes, there are indeed dash cams without wires. These wireless dash cams usually come with a battery pack or solar panel to power the device, allowing you to install and operate the camera without needing to run any cables from your car's electrical system. Wireless models are also typically smaller than wired cameras, making them easier to hide or mount in a non-intrusive manner. Additionally, some wireless models have features such as motion detection and automatic recording that can be set up even when no one is around for added convenience and security.
