DASHCAM · 4 CAMERAS · BYD
The most advanced dashcam for your BYD,
with the cameras it already has.
DashArc has the most advanced dashcam recording system for BYD today: it records all four 360° view cameras at once, into a single video, with no dashcam to buy or install.
Every recording is available on your phone, organized by day and linked to the trip and its telemetry. Watch, download and protect videos from anywhere.
Why it is the most advanced recording
- 4 cameras in one video, in a 2×2 grid like BYD’s four-camera view: front, rear and both sides, in sync.
- USB camera included: plug a webcam into the head unit and it joins the same file, in a strip above the car cameras.
- H.265 when the head unit supports it (smaller files), H.264 otherwise, with at least 24 frames per second per camera.
- Adjustable quality with one simple control, and ready-made defaults if you do not want to change anything.
- Car data in the video, such as speed and time, in the recording’s info strip.
- Record now to keep a specific moment without stopping continuous recording.
- Keeps recording even with the factory camera view open on the head unit (reverse and 360°).
Where videos are stored
- On the head unit, an SD card or a USB drive, organized by year, month and day.
- When space gets close to the limit, the oldest recordings are deleted automatically (you can turn that off), and you can also delete anything older than a number of days.
- DashArc always keeps some free space and, if the chosen card is not in the car, it records to the head unit and lets you know.
Everything on your phone
In the portal’s Recordings menu, each video has a thumbnail, date and length. Tap to watch on your phone, download in the browser or protect the important ones. In Trip history, the video opens right at the chosen moment of the drive. See also recordings on your phone and sentry mode for the parked car.
Pause where you do not need it
Mark safe places, such as your home garage, and choose to pause the dashcam and sentry mode there.
Frequently asked questions
What is the best dashcam for a BYD?
With DashArc, the dashcam is the car itself: all 4 360° cameras recorded into one video, with an optional USB camera, H.265 and recordings on your phone. No dashcam to buy.
Does the dashcam record all 4 cameras at once?
Yes. Front, rear and both sides are recorded together, in sync, into a single 2×2 file.
Does it record audio?
You can record cabin audio along with the video, in the dashcam settings.
Can I use an SD card or USB drive?
Yes. Choose head unit, SD card or USB drive; recordings go to the DashArc/Dashcam folder.
Does my phone need to stay connected?
No. Recording happens on the car’s head unit. Your phone is for watching, downloading and settings whenever you want.
