Viofo A229 Ultra 2CH
No rating shown: we have no owner rating for this camera from a source we can cite. Why
The A229 Ultra is the version where the rear camera stops being a witness and starts being evidence: both channels are 8MP Sony STARVIS 2 IMX678 modules recording 3840x2160, both on 140-degree f/1.8 lenses, both with HDR. That matters in one specific situation that dominates rear-camera complaints - somebody hits you from behind and drives off, and a 1080p 160-degree rear camera gives you a shape and a color where a 4K 140-degree one gives you a plate. It is also the reason this is the only camera in the catalog where both channels compute the same pixels-per-degree figure, about 27. The cost is card space: two 4K streams fill a 512GB high-endurance card quickly, and the loop is short enough that you want to be deliberate about locking clips. Otherwise it is the familiar A229 platform - supercapacitor power to 149 degrees Fahrenheit, 5GHz Wi-Fi, built-in GPS, Bluetooth, voice control, a 2.4-inch screen, a third infrared cabin module available, and the Type-C HK4 hardwire kit sold separately for parking modes.

Drivers whose realistic worst case is being hit from behind by someone who does not stop.
The description and the pros and cons above are written from published specifications, not from owner reports. Owner sentiment, where we have it, is in its own section below.
What the numbers mean here
The front camera records 3,840 horizontal pixels across a published 140-degree field of view, which is 27.4 pixels per degree — plate-legible at distance. The rear channel manages 27.4, so it resolves as finely as the front. How this is calculated, and what it does not tell you.
It runs on a supercapacitor rather than a lithium cell, so there is no battery to swell in a car parked in summer sun — the classic way a windshield-mounted camera dies. The maker publishes an operating range of -4°F to 149°F. Supercapacitors and heat.
Keeps a rolling buffer, so the seconds before an impact are saved as well as the impact itself. It is the most useful parking mode and the hungriest. The hardwire kit is a separate purchase, which is the line item people forget when budgeting. What each parking mode records.

Features
- Dual Sony STARVIS 2 IMX678 sensors - 4K HDR front and 4K HDR rear
- Both lenses 140 degrees at f/1.8, so both channels resolve identically
- Expandable with a 1080p infrared cabin module
- 5GHz Wi-Fi, built-in GPS, Bluetooth, voice control
- Supercapacitor, -4 to 149 degrees Fahrenheit
- 2.4-inch screen, microSD to 512GB
Where it is strong
- The only camera here where the rear channel matches the front on both resolution and field of view - about 27 px per degree at both ends
- A 140-degree rear lens instead of the usual 160 to 170, which is what actually makes a rear plate readable
- HDR on both 4K channels
- Same body, mounts, cables and hardwire kit as the rest of the A229 line
- Supercapacitor power with a 149F ceiling
Where it gives way
- Two 4K streams on one 512GB card means a much shorter loop than any two-channel rival here
- The narrower 140-degree rear lens trades peripheral coverage for plate detail - a side-swipe at the rear quarter can fall outside it
- Costs meaningfully more than the A229 Pro for an upgrade that only pays off in rear-end incidents
- Parking modes still require the separately sold HK4 hardwire kit
What owners say
We have not collected enough owner discussion about the Viofo A229 Ultra 2CH to write this section. We only summarise sentiment for cameras whose owners we have actually read, so this is left empty rather than filled in with something plausible. How we compare explains where the sentiment on other pages comes from.
