Overview
Dual Sony STARVIS sensors and an infrared cabin camera drive this DDPAI dash cam, recording the road ahead, the road behind and the interior at the same time. Footage saves to built-in eMMC memory with a microSD slot for more space, and the app connects over Wi-Fi and Bluetooth.
Buy it for full coverage in a rideshare or family car, with onboard memory guarding against card failures. Parking surveillance and remote cloud viewing both depend on extra hardware sold separately, and no microSD card comes in the box.
Who it's for
Rideshare drivers, parents and fleet operators who need evidence from every side of the car get the cabin channel and GPS logging. Drivers who only want a simple front camera will be mounting cameras they do not need.
Pros and cons
- Records front, rear and cabin at once
- Built-in storage backs up the card
- Infrared cabin night vision
- GPS with geofencing in the app
- Parking mode needs a separate hardwire kit
- MicroSD card not included
- Cloud viewing needs an extra LTE box
Performance notes
Night footage rests on the wide aperture lenses and STARVIS sensors, with AI ISP processing lifting dark scenes on the road channels and infrared lighting the cabin. A strong impact or vibration triggers emergency capture, and loop recording writes over old files as storage fills.
