4K frontSupercapacitorInfrared cabinVoice control5 GHz Wi-Fi

The Nexus 4 Pro is Vantrue's three-camera answer for people who carry passengers, and it is built around the idea that all three angles should be recorded at once rather than time-sliced. The front camera is an 8MP Sony STARVIS 2 IMX678 at 3840x2160/30 on a lens quoted at 155 degrees; the cabin channel is 1080p with four infrared LEDs on a 160-degree lens, and the rear is 1080p at 165 degrees. That 155-degree front lens is the number to watch: it is wider than the 140 degrees most of the Viofo line uses, so the same 3840 pixels cover more scene and the front camera resolves about 25 horizontal pixels per degree rather than 27. In exchange you get noticeably more of the intersection in frame. Power is a supercapacitor - Vantrue makes a point of it - rated -4 to 140 degrees Fahrenheit, and storage goes to a full 1TB, which three channels genuinely need. Connectivity is 5GHz Wi-Fi with a dual-system GPS logger and voice commands. Parking modes need a hardwire kit, sold separately.

Best for

Rideshare drivers who want 4K on the road and infrared on the cabin from one unit.

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 155-degree field of view, which is 24.8 pixels per degree — plate-legible a few lengths ahead. The rear channel manages 11.6, so it is the less detailed of the two. 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 140°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

Three channels at once: 4K front, 1080p infrared cabin, 1080p rear
Sony STARVIS 2 IMX678 front sensor with HDR
Four infrared LEDs on the cabin camera
microSD support to 1TB, which three channels actually need
5GHz Wi-Fi, dual-system GPS logger, voice control
Supercapacitor, -4 to 140 degrees Fahrenheit
2.45-inch screen with an optional Bluetooth remote

Where it is strong

1TB card support, which is the difference between a useful loop and a three-hour one on three channels
A proper 4K STARVIS 2 front camera rather than the downgraded front module most three-channel kits use
Four infrared LEDs give usable cabin footage with every light off
Supercapacitor rather than a lithium cell, on a camera that will sit in hot parking lots for a living
The remote control accessory means locking a clip does not mean reaching across the windshield
All three streams record simultaneously rather than switching between channels

Where it gives way

The 155-degree front lens spreads 4K over more scene than a 140-degree camera, costing about two pixels per degree of plate detail
Rear and cabin are only 1080p, so the front is the only channel that reads a plate at distance
Parking mode requires a hardwire kit that is not in the box
The 140F temperature ceiling is lower than the 149F Viofo and BlackVue quote

What owners say

Summarised from public owner discussion. Nothing here is our own testing.

The Nexus 4 Pro and the Viofo A229 Pro are the two cameras owners argue about most at this price, and the Vantrue usually wins on two specific things: a factory suction mount, which Viofo does not offer at all, and plate identification that owners who have compared footage rate highly.

The app is where the criticism lands. Owners want to get clips off over Bluetooth and describe the iOS app as the part of the package that has not kept up. The other pre-purchase question is always mounting: the cabin camera has to clear the rearview mirror, and people ask about placement in their specific car before committing.

Plan for power. Owners who try to run it from a mirror-mounted USB port find that works for driving but gives up parking mode entirely - if parking coverage is why you are buying a three-channel camera, budget for the hardwire kit at the same time.

What owners like

One of the two names that dominate 'what should I buy' discussion at this price, alongside the Viofo A229 Pro
Owners who compared footage side by side rate its license plate identification as more reliable than the cheaper Vantrue models
Vantrue offers a suction mount as a factory option, which owners who move a camera between vehicles or take it inside at night specifically look for
The dual supercapacitor setup and 512GB-plus card support are the specifications owners cite when choosing it over the older Nexus 4
Owners buying for parking-mode coverage after a vandalism incident consistently name it as the model they settled on

Common complaints

The iOS app is the recurring complaint - owners want Bluetooth access to clips and describe the current app as the weak part of the package
Mounting so the cabin camera is not blocked by the rearview mirror takes trial and error, and owners ask about placement before they buy
Vantrue's own SD card recommendations are inconsistent between listings, which leaves owners guessing about which card is actually supported
Owners repeatedly conclude that parking mode needs hardwiring, and that powering the camera from a mirror USB port means giving it up

What owners of the Vantrue Nexus 4 Pro ask

Nexus 4 Pro or Viofo A229 Pro?

These are the two cameras this decision usually comes down to. Vantrue offers a suction mount and a 1TB card ceiling; Viofo offers a slightly narrower front lens, which means more pixels per degree on a plate, and a better-regarded firmware record. Owners who move the camera between cars pick the Vantrue; owners who want the most plate detail pick the Viofo.

Where do I mount it so the cabin camera works?

High and central, but far enough from the rearview mirror that the mirror body does not block the cabin lens - which is tighter than it sounds on cars with large mirror housings. Owners generally dry-fit with the app running before committing the adhesive, and several recommend the suction mount for the first week for exactly this reason.

Can I power it from a mirror USB port instead of hardwiring?

For driving, yes. For parking mode, no - a mirror port is usually switched with the ignition, so the camera stops when the car does. Owners who want parking coverage end up hardwiring or fitting a battery pack regardless of what port is available.

Which memory card should I use?

A high-endurance card from a major brand. Vantrue's own recommendations differ between listings, which confuses owners, so the safe approach is a card explicitly rated for continuous surveillance video at 256GB or larger. Three channels are hard on a card and a standard consumer card will not last.
