Our score out of 10

Pros and cons

- Reads plates at night where rivals cannot
- Three-channel front, interior and rear
- Half the price of comparable big-brand units
What we didn’t
- Clumsy companion app
- Parking mode needs hardwiring
Our review
Night-time plate capture is the only meaningful test of a dash cam, and the A139 Pro reads plates in conditions where cheaper cameras produce mush. Three-channel recording covers front, interior and rear.
The app is clumsy and hardwiring for parking mode is a job most owners will pay for. The footage quality makes both worth tolerating.
