Main trade-off
VIOFO A329S 2CH
4K60 requires HDR off. 4K30 is the HDR choice.
Head-to-head
Choose U3000 Pro for front and rear radar-triggered parking with the supported constant-power installation. Remote LTE alerts also require compatible optional communications hardware, data service and the specified power arrangement. A329S 2CH is the local-display choice and offers 4K60 only with HDR off. Both selected packages record front and rear, with no cabin camera included.
Before you choose
A329S 2CH and U3000 PRO have the same 8.3-million-pixel front frame. Their included channel counts are 2 and 2, so coverage and the selected modes deserve more attention than the equal front label.
What this is based on
3840 × 2160 = 8294400 pixels. 3840 × 2160 = 8294400 pixels. This compares output dimensions, not sensor size, shutter speed, compression or readable plate distance.
Main trade-off
4K60 requires HDR off. 4K30 is the HDR choice.
Main trade-off
The optional LTE module and connected plan add cost.


Compare A329S 2CH and U3000 PRO by recorded views, card capacity, parking setup and clip review before choosing a dash cam.

Winner by situation
Both selected bundles record 4K front and 2K rear. Thinkware is screenless and uses the phone workflow, while VIOFO retains a local display. Neither selected package adds a cabin camera.
VIOFO provides a separate 4TB SSD option against the checked 512GB card limit on both. The drive and cabling can be worthwhile for local history, while Thinkware’s distinguishing investment is its radar and connected parking system. 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 separate, not simultaneous backup. Hybrid and Low Power Impact stay microSD-only. SSD capacity does not apply.
VIOFO’s low-power impact mode waits for an impact and then wakes the cameras. Thinkware’s radar can detect approaching motion while parked. Remote notification requires the specified optional communications hardware, service and power arrangement. A329S Low Power Impact needs a separate compatible high-endurance microSD and compatible GPS-mount hardwire power.
The A329S claim of under 40mA at 12.6V implies under 0.504W in that mode. This is not a measured consumption comparison with Thinkware or a promise of battery duration.

A329S 2CH 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 separate, not simultaneous backup. Hybrid and Low Power Impact stay microSD-only. SSD capacity does not apply.
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.
The A329S claim of under 40mA at 12.6V implies under 0.504W in that mode. This is not a measured consumption comparison with Thinkware or a promise of battery duration.
12.6V × 0.040A = 0.504W. No car-battery capacity, cutoff voltage, temperature or conversion loss is assumed.

VIOFO, A329S 2CH
A329S 2CH includes front and standard inside-window rear cameras. Its 4K60 front mode requires HDR off. Optional SSD recording needs its own compatible drive and cable, selected SSD storage and Privacy Mode off. Hybrid and Low Power Impact parking remain microSD-only.

Thinkware, U3000 Pro
The Pro keeps dual radar parking, adds a 512GB ceiling and supports an optional LTE module for away-from-car alerts.
