The Vantrue N4 Pro S is worth buying if you want front, cabin and rear coverage from a single dash cam. Its three STARVIS 2 sensors and buffered parking mode set it apart from simpler two-camera kits.
This vantrue n4 pro s review walks through what those features mean on a normal commute, how the install works, and when a cheaper dual-channel model makes more sense.
It's a flagship unit with flagship demands: you'll supply your own microSD card and add a hardwire kit to use parking mode. Read on to see whether that trade-off fits how you drive and park.
The Vantrue N4 Pro S at a glance
The N4 Pro S records 4K at the front and 2.5K from both the inside and rear cameras, all at 30 frames per second. That's three separate views in one system, which is more than most dash cams offer.
Vantrue N4 Pro S: Best for full three-channel coverage
- 4K + 2.5K + 1080P at 30 FPS
- Three STARVIS 2 sensors
- Buffered parking mode
- 5GHz WiFi and GPS
- Up to 1TB microSD
A three-camera flagship for drivers who want the cabin and the road behind them recorded as well as the road ahead. The rear camera rotates a full 360 degrees, and buffered parking mode saves footage from before an impact.
Pros
- Front, cabin and rear coverage from one system
- Three STARVIS 2 sensors with triple HDR
- Buffered parking mode captures the seconds before an event
- 5GHz WiFi and built-in GPS
- Supercapacitor rated for high heat
Cons
- Hardwire kit sold separately for parking mode
- Three-channel recording generates more heat than dual mode
- A 1TB card costs extra and isn't included
Its score of 8 reflects strong hardware and a broad feature set, held back by the extra purchases parking mode needs and the heat that triple recording creates. Our score weighs specs, features and buyer feedback against what you're shopping for.
The box holds the main camera, the rear camera, a 20ft rear cable, a car mount, a charging cable and an installation tool. It's a windshield-mount unit, so the main body sticks to the glass rather than sitting on the dash.
At 240 grams it's light enough that a clean mount holds it steady. The black housing blends into most interiors, which matters if you'd rather the camera didn't advertise itself.
Who should buy the N4 Pro S?
Buy it if you drive for work, carry passengers you want on record, or simply want the road behind you covered as thoroughly as the road ahead. The rotating rear camera also lets you point that lens at the trunk or the cabin if your needs change.
Rideshare drivers are the clearest fit. The inside camera puts passenger interactions on file, and the front and rear views document the traffic around the car.
Fleet users get the same three-way record across many vehicles.
Skip it if you only want the road ahead and behind. A two-channel camera costs less, runs cooler and stores more hours per card.
You'll find those in the alternatives below.
The specs that matter in daily use
The headline is triple STARVIS 2 sensors, and they're the reason this camera is worth the price. Each sensor is more sensitive in low light than the older chips many dash cams still use.
Vantrue says PlatePix combines those sensors with triple HDR to keep license plates readable in dim light or strong backlight. The company claims twice the plate accuracy in those conditions and readable plates at speeds up to 31mph at night.
The main lens opens to f/1.8, which lets in more light than a narrower aperture would. Together with the sensor and HDR work, that's the combination doing the heavy lifting after dark.
Coverage is wide: 155 degrees at the front, 160 inside and 165 at the rear. That spread leaves few blind spots, though wide lenses stretch detail at the edges of the frame.
The rear camera's real angle of view is listed at a full 360 degrees thanks to its rotation.
The rear camera's 360-degree rotation is the feature you'll notice most in daily use. Point it backward for the road, or twist it toward the cabin or trunk when you need that view instead.
Built-in GPS logs your route, speed and location in every clip. That's useful evidence if an incident turns into an insurance claim.
Voice control handles simple commands like taking a photo, so you keep your hands on the wheel.
Setting up the N4 Pro S in your car
Plan the install around the rear camera cable first, because that's the hardest part. The kit includes a 20ft rear cable, which reaches most cars, SUVs, minivans, trucks and buses.
Mount the main unit on the windshield where the wipers clear the glass and the lens sits below any tint band. Route the rear cable along the headliner and down the pillars, tucking it behind trim with the included installation tool.
Fit your microSD card before the first drive. Vantrue recommends its own industrial-grade U3 cards, which the company says last more than 3 years, and sells them in 64GB to 512GB sizes.
Format the card in the camera so the file system matches.
For parking mode, run the hardwire kit to the fuse box. That's the only way to keep the camera powered while the ignition is off.
If you'd rather not touch the fuse box, our guide to Vantrue vs Viofo dash cams covers how the two brands handle parking power.
Planning the card and cable run
Storage math is worth doing before you buy. A 64GB card fills quickly in three-channel mode, so if you want the 37 hours Vantrue quotes you'll need the 1TB card.
A 128GB or 256GB card is a reasonable middle ground for daily driving with regular downloads.
The 20ft cable is generous for sedans and SUVs. On a long bus or a truck with a deep cargo area, measure the run from windshield to rear glass before you commit.
If the cable falls short, no amount of mounting skill fixes it.
Living with three cameras and a 1TB card
The front and rear dual mode is the setting to remember for long trips and hot weather. Vantrue says it cuts heat by about 30% and saves power compared with triple recording, which matters in summer.
Three-channel mode is the reason to buy this camera, though, so most owners will run it by default. A 1TB card holds 37 or more hours of continuous triple recording, according to Vantrue.
Anything smaller fills faster.
Loop recording in 1, 2 or 3-minute segments overwrites the oldest clips automatically. The G-sensor locks event footage so it survives the overwrite cycle.
Downloads go over 5GHz WiFi to the Vantrue app. The faster band makes pulling a clip to your phone quick, which helps when you need to share footage with an insurer.
The app also handles settings and firmware updates, so the camera can improve over time without a card swap.
Parking mode and the hardwire question
Buffered parking mode is the best reason to add the hardwire kit. It records continuously but saves events from 10 seconds before an impact, so you get the lead-up, not just the moment of the bump.
All three cameras stay active in parking mode. Motion and impact detection trigger the save, and efficient recording helps stretch storage across a long stay.
That combination means a hit-and-run in a lot leaves you with the seconds before and after, not a clip that starts too late.
Vantrue is clear that the hardwire kit is sold separately. Factor that cost in when you compare the total against a rival that bundles accessories.
If you park on a street or in a shared lot, the added protection is usually worth it.
One more note on the kit: the camera uses a supercapacitor rather than a battery. That's the more heat-tolerant choice for a unit that sits in direct sun all day.
It also avoids the swelling and lifespan limits that come with lithium cells in a hot cabin.
Care and maintenance for a triple-camera unit
Heat is the thing to manage with three cameras running at once. Park facing away from the afternoon sun where you can, and use the dual mode in extreme heat to lighten the load.
Check the windshield mount now and then. A loose suction or adhesive pad lets the camera shift, which blurs plates and puts the frame off-center.
Wipe the lenses with a soft cloth, including the inside camera, which collects dust from the cabin. Clean glass in front of the main lens does more for image quality than any setting.
Review footage occasionally on the app. Confirm the card is still recording, the timestamps look right and the GPS data is logging.
Replace cards when they start showing errors, since dash cams write constantly. Industrial-grade cards are rated for that constant writing, and Vantrue's own line is tested for dash cam use.
The trade-offs before you buy
The N4 Pro S asks for more money and more accessories than a two-channel camera. The unit itself is the big cost, but the card and hardwire kit add up.
Triple recording also runs warmer and fills storage faster than dual mode. That's physics, not a flaw.
Vantrue addresses it with the cooler dual mode and the supercapacitor, but the trade-off remains.
The three-camera setup means more cable to route and more to set up. If you want a quick, low-fuss install, this isn't that camera.
Two-channel kits mount in less time and hide fewer wires.
Finally, wide lenses trade edge sharpness for coverage. The front view is 155 degrees, which catches more of the roadside but distorts plates near the frame edge.
That's typical for dash cams in this class.
Alternatives worth a look
If the N4 Pro S isn't quite right, these three cameras cover different priorities. Each one earns its badge for a specific kind of buyer.
For a two-channel setup with a card included
The REDTIGER 4K STARVIS 2 Dashcam Front Rear scores 9.4 and bundles storage, so you skip the card purchase. It also has a touch screen and voice commands.
Its 5.8GHz WiFi is rated for downloads up to 20MB/s. Read our REDTIGER F7NP review for how its sibling compares.
For a small, simple camera
The REDTIGER F7NP scores 8.7 and covers front and rear without the third cabin view. Its F1.5 aperture and STARVIS 2 sensor handle night driving well.
It's the easier install if you don't need the inside camera. See how a tiny single-lens unit compares in our Garmin Dash Cam Mini 3 review.
For a different brand's take on dual channel
If you're weighing brands, the VIOFO A229 Plus is another dual-channel option to compare against this Vantrue. Both target drivers who want solid night footage and reliable parking protection.
Verdict: is the Vantrue N4 Pro S right for you?
Buy the Vantrue N4 Pro S if you want three views from one camera and will use buffered parking mode. Its triple STARVIS 2 sensors, rotating rear lens and 5GHz WiFi make it a strong flagship for rideshare drivers, fleet users and anyone who wants the cabin on record.
The score of 8 reflects that hardware and its extra costs.
Skip it if a two-channel kit covers your needs. The REDTIGER 4K STARVIS 2 bundles a card and scores higher for simpler setups, while the REDTIGER F7NP is the compact pick.
The N4 Pro S earns its place when the third camera and buffered parking protection matter to you. That's the bottom line of this vantrue n4 pro s review: buy it for coverage, not for simplicity.
Frequently asked questions
Does the Vantrue N4 Pro S come with a memory card?
No. Vantrue sells the N4 Pro S without a microSD card and recommends its own industrial-grade U3 cards in 64GB to 512GB sizes.
The camera supports cards up to 1TB, so plan for the card cost when you compare it with a rival that bundles storage.
How long does the Vantrue N4 Pro S record in three-channel mode?
Vantrue says the camera can store 37 or more hours of continuous 4K three-channel recording when you fit a 1TB card. Smaller cards fill faster because the front, inside and rear cameras all write at once, so the front and rear dual mode stretches storage further.
Can the Vantrue N4 Pro S record while the car is parked?
Yes, it has a buffered parking mode that keeps all three cameras active and saves footage from 10 seconds before an impact. You need the separate hardwire kit to connect it to the fuse box for round-the-clock power.
Is the inside camera on the Vantrue N4 Pro S always recording?
The camera records all three views in its default three-channel mode. You can switch to the front and rear dual mode, which leaves the cabin camera out and runs cooler, so the inside view only records when you choose the triple setup.
