We read VIOFO's listing for the A229 Pro 2CH on 9 October 2026 and added up what you need to buy to use every feature it advertises. We have not mounted this camera in a car.

Research-based score out of 10. The overall score is the average of the four parts below.
- Sony STARVIS 2 sensors front and rear
- HDR on both channels
- Supercapacitor instead of a battery
- 2.4 and 5 GHz Wi-Fi, built-in GPS
- No memory card included
- Parking mode needs a $25.99 hardwire kit
- Only 14 days to return
- Recording bitrate is not published
The short answer
Consider it if
- You want readable number plates at night from both the front and the rear camera.
- You park in the sun. A supercapacitor copes with heat better than a lithium battery.
- You are willing to hardwire it, or pay someone to.
Skip it if
- You want to plug in and drive with nothing else to buy.
- You only need a front camera. The 1-channel version is $40 less.
- You want cloud video or a built-in LTE connection.
The real price is about $416
The listing is clear that a microSD card is optional and not included, and that the HK4 hardwire kit is optional too. Without a card the camera records nothing. Without the hardwire kit it has no power when the engine is off, so parking mode does not run.
| Item | VIOFO's price |
|---|---|
| A229 Pro 2CH | $349.99 |
| VIOFO microSD card (from) | $39.99 |
| HK4 hardwire kit | $25.99 |
| Total | $415.97 |
You can use another brand of card, but pick one sold as high endurance. Dash cams rewrite the card constantly and ordinary cards wear out. The camera accepts up to 512 GB.
What the sensors tell you
The front camera uses Sony's IMX678, an 8-megapixel sensor, behind an f/1.8 lens with a 140-degree view. The rear uses the 5-megapixel IMX675 at f/1.9 and 160 degrees. Both record at 30 frames a second with HDR.
Eight megapixels is exactly what 4K needs (3840 x 2160 is 8.3 million pixels), so the front video is true 4K and not upscaled. The same goes for the rear: 2560 x 1440 is 3.7 million pixels from a 5-megapixel sensor.
One figure is missing. VIOFO does not publish the recording bitrate, which decides how much detail survives compression and how many hours fit on a card. Ask if you need to plan storage.
The award and the return window
The page title calls this "Wirecutter's #1 Pick". We did not verify that claim, and picks change. If it matters to you, check the publication's current guide yourself.
VIOFO's return window is 14 days, shorter than most direct sellers. The warranty is 18 months. The camera runs from minus 20 C to 65 C, which covers a parked car in most climates.
