Many dash cams come with Wi-Fi connectivity and a companion app that allows you to connect your phone to the dash cam and transfer footage wirelessly. You can also use the app to watch live footage, adjust settings, and download and share footage directly from your phone. Some dashboard cams also come with a built-in screen that allows you to watch footage on the device itself. However, it’s important to note that watching footage on your phone while driving is illegal and dangerous. It’s recommended to review the footage only after you have stopped driving, or ensure your phone is mounted on your dashboard for hands-free use.
