Viofo A229 Pro vs A229 Plus: Which Should You Buy in 2026?

Viofo A229 Pro vs A229 Plus: which should you buy?

Buy the A229 Plus 2CH if most of your driving is in town: it records 2K front and 2K rear on matching Sony STARVIS 2 IMX675 sensors, and Viofo lists it at $229.99 (checked October 2026). Buy the A229 Pro 2CH if you drive highways or need plates readable two or three cars ahead: its 4K IMX678 front camera holds detail at distance and the CPL filter is in the box, at $349.99 from Viofo. The rear camera, the parking modes and the body are the same on both.

This page is built from Viofo's own product pages for both cameras, Viofo's A329S and A229 Ultra pages for the step-up options, CEN UK's published comparison and a DashCamTalk owner thread, rather than first-hand use.

What the two cameras share

Viofo's spec sheets list the same platform under both names: a Novatek chipset, front HDR plus rear HDR, dual-band 2.4GHz and 5GHz Wi-Fi, built-in GPS, Bluetooth for the optional BTR200 remote, voice control, and a parking mode with auto event detection, time-lapse and low-bitrate recording, including buffered parking mode. Both are supercapacitor cameras with no battery, both list an operating temperature of -20°C to 65°C, and both run on the same DC 5V / 2A input. Both accept microSD cards up to 512GB. Both use the same HK4 hardwire kit, which Viofo prices at $25.99 and describes as required for parking mode; neither records while parked on the included car charger alone.

The rear camera is identical too: a Sony STARVIS 2 IMX675 5MP unit recording 2K (2560 by 1440) at 30fps through an F1.9 lens with a 160° field of view. Viofo's own FAQ settles the whole comparison in three sentences: "The A229 Pro records 4K front (IMX678 sensor) + 2K rear. The A229 Plus records 2K front + 2K rear (both use IMX675 sensor). The Pro includes a CPL filter in the box; the Plus requires a separate purchase."

Where they differ

The front sensor is the whole decision

Viofo describes the A229 Pro as "the industry's first dashcam using two flagship Sony STARVIS 2 image sensors, respectively for front and rear cameras", and the Plus as the first to use two IMX675 sensors, "which offer 2.5 times wider dynamic range and higher light sensitivity than the STARVIS tech". Strip the marketing and the difference is one part: the Pro's front sensor is the physically larger 1/1.8-inch IMX678 with 8MP, recording 4K at 30fps, while the Plus uses the 1/2.8-inch IMX675 with 5MP, recording 2K at up to 60fps. Everything behind the front lens, from the HDR processing to the GPS stamp, is shared.

What that buys you is plate legibility at distance. CEN UK's comparison puts it plainly: "The A229 Plus is enough for most drivers. 2K front and rear reads a plate at a normal following distance, day or night. The A229 Pro earns its money at distance." The same piece notes that 4K "gives you more room to crop into a frame without the image falling apart, which is what you end up doing when you send footage to an insurer or the police." If the incidents you worry about are the car in front braking or someone reversing into you, the plate is large in frame and 2K resolves it. If you picture a hit-and-run two lanes over at highway speed, the Pro's extra pixels are the whole reason to spend more.

The Plus has one trick the Pro lacks: its front camera can record 2K at 60fps. Viofo lists the Pro's front channel at 30fps only. Sixty frames per second smooths fast motion and gives you twice as many frames to pause on when a plate flashes past, which partly offsets the resolution gap in close-range, high-speed moments. For a commuter who mostly films stop-and-go traffic, that is a fair trade.

Night footage: an owner's observation

Both cameras carry STARVIS 2 sensors and HDR on every channel, and Viofo's pages make the same low-light claims for each. A long-running DashCamTalk thread comparing the two includes a member's note that at night "the A229 Plus the image is more nice compared to A229 Pro but the A229 Pro reading car license numbers is better." That matches the sensor logic: the Plus's 2K image can look cleaner when viewed whole, while the Pro's 4K frame holds more recoverable detail when you zoom into a plate. Treat it as one owner's view, not a measurement, but it is consistent with what the spec sheets predict. Our Garmin vs Viofo night legibility comparison covers the broader question of what makes plates readable after dark.

The CPL filter is a real cost difference

Glare off a dashboard washes out footage on sunny days, and a circular polarizer is the standard fix. Viofo's A229 Pro page lists "CPL Front: CPL-200 Included / Rear: CPL-300 (Optional)", while the A229 Plus page lists "CPL Front: CPL-200 (Optional) / Rear: CPL-300 (Optional)". If you intend to run a polarizer anyway, which we recommend for anyone in a sunny climate, the Pro's sticker price already contains it and the Plus's does not. Factor that in before you compare the two prices.

Storage, transfers and accessories are identical

Both cameras accept cards up to 512GB and Viofo sells its own U3 A2 V30 industrial high-endurance card in 64GB to 512GB sizes from $39.99. A 4K front stream fills a card faster than a 2K stream, so Pro buyers should lean toward the larger sizes; our microSD card guide for dash cams explains what the endurance ratings mean. Phone transfers are the same on both: dual-band Wi-Fi, and a wired USB 2.0 Type-C option that Viofo says reaches "up to 20MB/s on iPhone 16". Both pair with the BTR200 remote, both take the HK4 kit, and both share the same mounts, so an A229 Plus owner can move to a Pro later without replacing anything but the camera.

Should you stretch to the A329S or the A229 Ultra instead?

Two newer Viofo cameras sit above the Pro, and they change the calculus for some buyers. The A329S 2CH lists at $459.99 at Viofo, with the single-channel A329S 1CH at $379.99. Viofo's own FAQ describes what the extra money buys over the A229 Pro: "Wi-Fi 6 (4× faster transfers), external SSD support up to 4TB, and two brand-new parking modes — Low Power Impact Detection and Hybrid Parking Mode." It also records its 4K front channel at 60fps where the Pro is limited to 30fps, and Viofo claims "A one-minute 4K clip reaches your phone in under 10 seconds." The A329S uses a different hardwire kit, the HK6, which Viofo prices at $32.99 and which unlocks its hybrid parking mode and battery-voltage monitoring.

The A229 Ultra 2CH, at $409.99, is the dual-4K option: Viofo lists "4K front + 4K rear @ 30fps Dual Sony STARVIS 2 IMX678 8MP sensors". If your real worry is being rear-ended by someone who drives off, a 4K rear camera is the upgrade that matters, and neither the Plus nor the Pro offers one.

If the Pro appeals because you want the best front image Viofo makes in this body, the A329S is the better buy for a modest step up. If the Pro appeals because it is the cheapest 4K Viofo, buy the Pro; the A329S's advantages are parking-mode and transfer-speed features, not a sharper daytime image. Our Viofo A229 Pro review goes deeper on the Pro on its own, and our Vantrue vs Viofo brand comparison covers the main rival's equivalents.

Who should buy which

• Buy the A229 Plus 2CH if you drive mostly in town, want front and rear coverage with buffered parking mode, and would rather put the saved money toward a hardwire kit and a bigger card. Check the A229 Plus price at VIOFO Ltd.
• Buy the A229 Pro 2CH if you spend real time at highway speed, want to identify vehicles that are not directly ahead of you, or want the CPL filter included. Check the A229 Pro price at VIOFO Ltd.
• Buy neither if you need a 4K rear camera (A229 Ultra) or you want the fastest transfers and hybrid parking mode (A329S). The 1CH versions of both the Plus and the Pro exist for front-only installs, and the 3CH versions add a 1080P infrared cabin camera for rideshare use.

Whichever you choose, plan for a high-endurance card rather than a generic one; constant loop recording wears ordinary cards out, and the 4K Pro fills a card faster than the Plus. Our hardwiring guide walks through the parking-mode install both cameras need, and the card guide linked above covers which sizes make sense for each.

FAQ

Is the A229 Plus good enough to read license plates?

At normal following distances, yes. CEN UK's assessment is that 2K front and rear "reads a plate at a normal following distance, day or night", and Viofo's spec sheet gives the Plus the same HDR, the same F1.8 front lens and the same STARVIS 2 sensor family as the Pro. The Pro's advantage appears when the vehicle is far away, moving fast relative to you, or small in the frame.

Does the A229 Pro use more power or run hotter than the A229 Plus?

Viofo does not publish power-draw or internal temperature figures for either camera. Both pages list the same DC 5V / 2A input and the same -20°C to 65°C operating range, and both are supercapacitor designs with no battery to swell in the heat. Owners sometimes report that 4K cameras feel warmer to the touch, but there is no maker data to confirm a difference, so we will not print one.

Do I need the hardwire kit?

Only for parking mode. Viofo's note on the A229 Plus page is explicit: "VIOFO hardwire kit is required for Parking Mode." On the car charger alone, both cameras record while you drive and stop when the ignition goes off. The HK4 kit is the same part for both cameras and lists at $25.99 at Viofo; our buffered versus time-lapse parking mode explainer covers which parking setting to use once it is installed.

Can I add a cabin camera later?

Viofo sells 3CH versions of both the Plus and the Pro with a 1080P infrared cabin camera, and the Pro 3CH lists at $379.99. If you think you might want interior recording, buying the 3CH kit from the start is cheaper than adding a camera later, because the interior unit is sold as part of the kit.

Which one should a first-time dash cam buyer choose?

The A229 Plus 2CH. It has every feature that matters for evidence, including GPS speed stamping and buffered parking mode, and the money saved covers the hardwire kit, a CPL filter and a large card with room to spare. Move to the Pro only if your driving genuinely involves identifying distant or fast-moving vehicles. Check the current A229 price at VIOFO Ltd.
