Dash cams without a display screen generally require the use of a related mobile app for operation. After logging in and registering an account, completing a series of operations will enable the app to perform the dash cam recording function.

I often use dash cams without screens, mainly relying on mobile apps to review footage. Most screenless models on the market now support WiFi or Bluetooth connections, like popular brands such as Xiaomi and 70mai, which come with dedicated apps. After installing the app, just turn on the dash cam's WiFi and connect your phone to view or playback recordings in real time. The advantage is the larger phone screen, easier operation, and the ability to directly export videos for sharing or backup. Remember to check if the app supports your device model—sometimes you might experience slight lag during connection, but usually, restarting the device fixes it. I make it a habit to regularly save important clips to the cloud or computer in case the memory card gets full or lost. This design saves a lot of space, and when installed near the rearview mirror, it doesn’t obstruct the view, making it especially suitable for compact cars.

As a daily driver, I've also encountered the issue of reviewing footage from a dashcam without a screen. The simplest solution is to remove the memory card and insert it into a computer or a phone card reader. After each parking, take out the microSD card and use a card reader or your phone's OTG function to directly access the video files. The file formats are usually MP4 or AVI, which can be opened by double-clicking on a computer, while a file manager app is needed on a phone. It's advisable to choose high-quality memory cards and avoid off-brand ones to prevent video corruption. The advantage is that the device is compact and inexpensive, but the downside is the manual insertion and removal of the card, which isn't ideal for urgent viewing. I make it a habit to transfer data to the cloud or a hard drive every other week to ensure the safety of crucial evidence.

From my experience tinkering with electronic devices, dashcams without screens mainly offer two ways to view footage: via mobile apps or computer connections. First, ensure the dashcam is powered on and supports connectivity features. For app control, common practice involves downloading the manufacturer's software, such as 'XingYingTong' for DDPai models. After connecting to WiFi, you can replay or download videos within the app. For computer access, simply connect via USB cable or card reader and play the video files using software like VLC or media players. Helpful tips include checking memory card capacity and format (FAT32 ensures better compatibility), plus regular formatting to prevent lagging or file loss.
