Video Quality
The Viofo A139 Pro records at 4K with a 150° field of view. In daylight, footage is sharp enough to clearly read number plates at motorway speeds. The wide 150° lens captures more of the road ahead than narrower competitors.
Is the Viofo A139 Pro Good for Insurance?
Yes. The Viofo A139 Pro provides timestamped footage with GPS coordinates showing your speed and location that is accepted by most UK insurers as evidence. This is particularly useful for "crash for cash" incidents — staged collisions that cost UK drivers an estimated £340 million per year. Having clear dash cam footage can invalidate a fraudulent claim against you before it reaches court.

Installation
The Viofo A139 Pro attaches to your windscreen using the included mount. A basic install (cable tucked behind the headliner to the 12V socket) takes around 20–30 minutes. For parking mode, a hardwire kit connects directly to your fuse box — most independent fitters charge £30–£50 for this.
