The catch
VIOFO A329S 3CH
Running all three cameras together caps the front stream at 4K30.
Side by side
VIOFO A329S 3CH vs Thinkware U3000 PRO: A radar-focused two-camera parking setup, or cabin recording that is included
Quick verdict
Decide between infrared cabin evidence that comes included and a two-camera parking system built around radar.
Before you buy
Why, and what it costs you
Pick a front-frame size that fits the view you really need
An 8.3-million-pixel front frame is shared by A329S 3CH and U3000 PRO. Their included channel counts are 3 and 2, so coverage and the selected modes call for more attention than the equal front label.
Where this comes from
3840 × 2160 = 8294400 pixels, and 3840 × 2160 = 8294400 pixels again. Only output dimensions are compared, not sensor size, shutter speed, compression or readable plate distance.
The catch
Thinkware U3000 Pro
The optional LTE module and a connected plan cost extra.

VIOFO A329S 3CH
- Why pick it
- Passenger-cabin recording is needed now
- You want a separate SSD archive. An A329S SSD driving archive needs a separately purchased compatible drive and VIOFO cable, suitable GPS-mount power, SSD selected and Privacy Mode off. One target records, and explicit card-to-SSD copying is a separate step. It does not create a simultaneous backup. Hybrid and Low Power Impact stay microSD-only. SSD capacity does not apply.
- The catch
- Running all three cameras together caps the front stream at 4K30.
Thinkware U3000 Pro
- Why pick it
- Front and rear radar parking is your aim
- A screenless connected installation is your preference
- The catch
- The optional LTE module and a connected plan cost extra.

What this page compares
Before you pick a dash cam, weigh the A329S 3CH against the U3000 PRO on recorded views, card capacity, parking setup and clip review.

A trip on which the directions recorded count for more than the headline 4K label
Besides front and rear cameras, the A329S 3CH includes an infrared cabin camera. The U3000 PRO bundle in this comparison has two cameras. A compatible optional cabin accessory would have to be specified and priced separately.

A long shift that comes with a defined clip-retention requirement
A329S supports a separate compatible SSD up to 4TB. Its Hybrid and Low Power Impact parking need a separate compatible high-endurance microSD card up to 512GB. 512GB is the upper limit. Smaller cards are allowed. Thinkware’s checked card ceiling is 512GB. Storage expansion and remote alerts address different needs and should not be treated as substitutes. An A329S SSD driving archive needs a separately purchased compatible drive and VIOFO cable, suitable GPS-mount power, SSD selected and Privacy Mode off. One target records, and explicit card-to-SSD copying is a separate step. It does not create a simultaneous backup. Hybrid and Low Power Impact stay microSD-only. SSD capacity does not apply.

A parked car that depends on the correct power and trigger behavior
In rideshare, the included interior view may settle the choice right away. For a private vehicle that sits parked, Thinkware’s radar and optional connected alert installation can matter more than recording passengers. Check the recording consent rules wherever the vehicle operates.

In practice
Differences you will notice
Pick a front-frame size that fits the view you really need
An 8.3-million-pixel front frame is shared by A329S 3CH and U3000 PRO. Their included channel counts are 3 and 2, so coverage and the selected modes call for more attention than the equal front label.
How we worked this out
3840 × 2160 = 8294400 pixels, and 3840 × 2160 = 8294400 pixels again. Only output dimensions are compared, not sensor size, shutter speed, compression or readable plate distance.
Put storage on a common footing without promising how long it records
A329S 3CH has a checked 4000GB external SSD ceiling versus 512GB microSD for U3000 PRO. The larger nominal option is 7.8 times the smaller, before formatting and protected-file use. An A329S SSD driving archive needs a separately purchased compatible drive and VIOFO cable, suitable GPS-mount power, SSD selected and Privacy Mode off. One target records, and explicit card-to-SSD copying is a separate step. It does not create a simultaneous backup. Hybrid and Low Power Impact stay microSD-only. SSD capacity does not apply.
How we worked this out
Use decimal capacity, with 1TB = 1000GB. 4000 ÷ 512 = 7.8. Capacity is not a bitrate or runtime measurement. A329S Hybrid and Low Power Impact stay microSD-only.
One required rideshare view goes unfilled by the selected Thinkware bundle
Should the requirement be front, rear and cabin, A329S covers it with all three cameras included. The selected U3000 PRO two-camera kit provides two of those three views.
How we worked this out
Required view count = 3. Included coverage is 3 versus 2. Optional Thinkware expansion is not denied here, since it sits outside the compared bundle.
Option A

VIOFO, A329S 3CH
A329S 3CH
The A329S 3CH comes with a front camera, a standard inside-window rear camera and one IR fisheye cabin camera. Running all three means the front records at 4K30. SSD recording is optional and calls for its own compatible drive and cable, SSD storage selected and Privacy Mode off. Hybrid and Low Power Impact parking still work only with microSD.
- Best for
- Front, rear and infrared cabin evidence kept locally
Facts we checked
- 3840 × 2160 at the front, 2560 × 1440 at the rear
- An additional infrared cabin camera at 2560 × 1440
- Up to 512GB of microSD, plus a separate SSD up to 4TB
- GPS and Wi-Fi 6
Option B
Thinkware, U3000 Pro
U3000 Pro
Dual radar parking stays on the Pro, along with a 512GB ceiling and optional LTE support for alerts while you are away from the car.
- Best for
- Premium parking coverage, with a documented upgrade path for remote alerts
Facts we checked
- Cards up to 512GB are supported by the U3000 Pro, which records 4K front and 2K rear video.
- Around detected events, dual radar parking records a 20-second clip.
- An OBD-II power cable comes with the checked package, while LTE remains an optional module.

| Rear and cabin arrangement | Rear 2560 × 1440, cabin 2560 × 1440 with IR | Rear 2560 × 1440. No included cabin camera | Enlarging an existing front frame cannot bring back a recording direction that is missing. Check the exact camera bundle included and the usable view once installed. |
| Local recording capacity | microSD up to 512GB, optional SSD up to 4TB (compatible drive and VIOFO cable sold separately) | 512GB microSD | A329S supports a separate compatible SSD up to 4TB.

| Review controls and network | Button-operated display, Wi-Fi 6 | No display, Dual-band Wi-Fi | Reviewing clips works differently with a local display. Direct Wi-Fi transfer needs a phone nearby, and it should not be mistaken for cellular remote access. |
| Parking installation | Hybrid and Low Power Impact: separate compatible high-endurance microSD only (up to 512GB), compatible GPS-mount hardwire power. Set Hybrid time or voltage, and voltage control needs HK6. | Front and rear radar parking detection. Remote alerts need the supported connected installation and optional LTE module with data service | In rideshare, the included interior view may settle the choice right away. For a private vehicle that sits parked, Thinkware’s radar and optional connected alert installation can matter more than recording passengers. Check the recording consent rules wherever the vehicle operates. |
| Included optical and storage accessories | Included front CPL filter | Confirm the selected CPL bundle | Confirm the exact bundle you are buying. Polarizers cut some reflections, and a starter card still has to offer enough capacity and endurance for the selected modes. |
Trade-offs
What each pick costs you

Look at the controls and the parked-car install
In rideshare, the included interior view may settle the choice right away. For a private vehicle that sits parked, Thinkware’s radar and optional connected alert installation can matter more than recording passengers. Check the recording consent rules wherever the vehicle operates.
What this page can’t tell you
- This page makes no claim of any real-world plate-reading, night-vision or reliability test.
- A capacity calculation can’t promise a number of retention days, because bitrate, protected clips, formatting and parking use all change the result.
- Parking features depend on the right constant power. Don’t assume a low-power wake-up mode saves footage from before an impact.
