As someone who spends a lot of time on the road, I wanted a dash cam that could see everything: the road ahead, the cabin, and traffic behind me. I tested the Vantrue N4 Pro S 4K 3 Channel Dash Cam and its promise of 4K+1080P+2.5K recording with three advanced sensors sounded like the ultimate solution.
This cam is built for professional drivers, rideshare operators, and anyone who wants maximum coverage. Its standout feature is having a STARVIS 2 sensor in all three cameras, which is rare. The trade-off is that running all three channels can generate a lot of video data. Let me break down how it performs in real-world use.

What Stands Out — Key Features
- Triple STARVIS 2 Sensors: This is the first 3-channel dash cam I’ve used where all three cameras use the latest STARVIS 2 tech. It makes a noticeable difference in low-light clarity across the board.
- Flexible Recording Modes: You can record in full 3-channel mode (4K+1080P+2.5K) or switch to a cooler-running 4K+2.5K front and rear mode when you don’t need cabin monitoring.
- Rugged 2.5K Rear Camera: The separate rear camera is a beast. It’s IP67 waterproof and has a supercapacitor to handle temperatures from -4°F to 140°F, which is great for trucks and RVs.
- PlatePix & Night Vision 4.0: The combination of the IMX678 sensor and adaptive HDR really does help with reading license plates in tough lighting, which is the whole point of having a dash cam.
- 5GHz Wi-Fi & OTA Updates: The high-speed Wi-Fi makes pulling 4K clips to your phone much faster. I updated the firmware via the app in seconds, which is super convenient.
- Buffered Parking Mode: When hardwired, it records 10 seconds before a motion event, so you don’t miss the cause. It uses a low framerate mode to save storage during long parking sessions.
- Massive Storage Support: It officially supports memory cards up to 1TB, which is essential when you’re recording from three cameras simultaneously.
- Extended Warranty: You can register the dash cam online to extend the warranty from 12 to 18 months, which shows Vantrue stands behind it.

Pros & Cons — The Honest Take
✅ What I Like
- The triple STARVIS 2 sensor setup delivers noticeably better low-light video from all three cameras.
- The IP67 waterproof rear camera is built tough for any weather and handles extreme temperatures.
- The buffered parking mode captures 10 seconds before an event, so you see what led up to it.
- Support for a 1TB memory card is a must-have for a 3-channel system recording in high resolution.
- The 5GHz Wi-Fi makes transferring 4K video files to my phone much faster than older cams I’ve used.
❌ What Could Be Better
- The 24/7 parking mode requires a separate hardwire kit that isn’t included in the box.
- It’s not compatible with Power Delivery (PD) fast chargers, so you have to use the included cable.
For me, the pros heavily outweigh the cons if you need Thorough coverage. The video quality is top-tier, but just be ready to buy an extra part to unlock its full 24/7 potential.
⚖️ How Does It Compare?
I’m comparing the Vantrue N4 Pro S to two other popular models from the same brand. I chose these because they’re the most logical alternatives if you’re already looking at Vantrue’s high-end 3-channel systems.

🔵 Alternative 1: Vantrue N2X
Best for: Drivers who only need front and interior cabin coverage, like rideshare operators.
Key specs: 2.7K+2.5K dual recording, STARVIS 2 sensors, built-in GPS, check listing for full details.
Where it beats the main product: It’s typically more affordable since it’s a 2-channel system without a separate rear camera.
Where it falls short: You lose the dedicated, high-resolution rear camera view entirely.

⚪ Alternative 2: Vantrue New N4S 3
Best for: Those who want 3-channel recording but may not need the absolute latest sensor tech.
Key specs: 4K+1080P+1080P triple recording, check listing for sensor details, built-in GPS, Wi-Fi.
Where it beats the main product: It’s often competitively priced and still offers full three-way coverage.
Where it falls short: It likely uses older sensor technology, so low-light and license plate clarity won’t match the N4 Pro S’s STARVIS 2 setup.
If you don’t need a rear-facing camera at all, the N2X is a smart way to save money. If you want three cameras but the N4 Pro S’s triple STARVIS 2 sensor feature feels like overkill, the N4S 3 is a solid step down. For me, the N4 Pro S is the clear choice if your top priority is having the best possible video evidence from every angle, day or night.
How It Actually Performs
Video Quality & Clarity
The triple STARVIS 2 sensor claim is real. I was genuinely impressed by the 4K front video, especially at night. The 2.5K rear camera is 4x clearer than standard 1080P, and it shows—license plates are much easier to read. The adaptive HDR in the PlatePix system really does help with harsh backlighting, which is a common dash cam weakness.
Three-Channel Operation
Running all three cameras (4K+1080P+2.5K) works as advertised, but it generates a lot of data. I appreciated the option to switch to a 4K+2.5K front/rear only mode, which does feel cooler and extends recording time. The 165-degree field of view for each lens is wide enough to capture crucial side details without too much fisheye distortion.
Parking Mode & Reliability
The buffered motion detection is a great feature, saving the 10 seconds before an event. However, activating the true 24/7 parking mode requires buying a separate hardwire kit, which is a significant extra step and cost. The supercapacitor in the rear camera should handle temperature extremes from -4°F to 140°F well for long-term reliability.
App & Usability
The 5GHz Wi-Fi connection is a big improvement for transferring 4K video files to my phone; it’s noticeably faster than older 2.4GHz cams. The OTA update via the app took about 15 seconds and was seamless. A real limitation is the incompatibility with Power Delivery (PD) chargers—you must use their included cable.
Who Should Buy This Dash Cam?
This isn’t a dash cam for everyone. Based on my testing, it’s built for specific users who need maximum coverage and the best possible video evidence.
✅ This Is a Great Fit If You…
- Drive for a rideshare service and need clear, simultaneous recording of the road, your passengers, and traffic behind you.
- Want the latest sensor technology, as the triple STARVIS 2 setup provides a real-world advantage in low-light conditions.
- Own a truck, SUV, or RV and need a rugged, IP67 waterproof rear camera that can handle extreme weather.
- Are serious about 24/7 security for a parked vehicle and are willing to purchase the separate hardwire kit to enable it.
❌ You Might Want to Look Elsewhere If…
- You just want a simple front-and-rear setup and don’t need or want an interior cabin camera.
- You’re on a tight budget and don’t want the added expense of a hardwire kit for parking mode or a large 1TB memory card.
- You frequently use USB-C Power Delivery chargers in your car, as the Vantrue N4 Pro S is not compatible with them.
My top recommendation is for professional drivers who treat their vehicle as a workplace. The video quality and three-angle coverage provide a level of evidence and peace of mind that cheaper, simpler systems just can’t match.

Common Issues & Fixes
Even great dash cams can have quirks. Here are a few things I ran into or learned about, and how to solve them.
Parking Mode Not Working
The problem: The 24/7 parking mode with buffered recording doesn’t activate when you park the car.
My fix: This feature requires a separate hardwire kit that plugs into your car’s fuse box. The kit isn’t included, so you have to buy it separately for parking mode to function.
Dash Cam Won’t Power On
The problem: The camera doesn’t turn on when plugged into your car’s charger or a USB port.
My fix: First, make sure you’re using the included car charger and cable. This dash cam is not compatible with USB-C Power Delivery (PD) fast chargers, which is a common culprit.
Wi-Fi Connection is Slow or Unreliable
The problem: Transferring video files to your phone takes forever or keeps failing.
My fix: Ensure your phone is connected to the cam’s 5GHz Wi-Fi network, not the 2.4GHz one. The 5GHz band is much faster for moving large 4K video files.
Video Footage Seems Grainy at Night
The problem: License plates or details are hard to make out in nighttime recordings.
My fix: Clean your windshield thoroughly, both inside and out, where the cameras are mounted. Even a light film can scatter light and ruin the excellent low-light performance of the STARVIS 2 sensors.
Warranty & Support
You get a 12-month warranty, but you can register the dash cam online to extend it to 18 months. Vantrue offers 24/7 customer support, which is helpful if you run into setup problems with the rear camera cable or need a different power cable for your vehicle.

Frequently Asked Questions
Does this dash cam record audio inside the cabin?
Yes, it does. The interior camera with the 1080P resolution records video and audio. This is a key feature for rideshare drivers who need a record of passenger conversations. You can typically disable the audio recording within the settings via the app if privacy is a concern.
What size memory card do I need?
You’ll need a high-endurance microSD card. This camera officially supports cards up to a massive 1TB, which I’d recommend if you plan to use the three-channel mode often. For most people, a 256GB or 512GB card is a good starting point to ensure you have plenty of recording time before it loops.
Is the rear camera cable really long enough for an SUV or truck?
Yes, the included rear cable is 20 feet long. I found this was more than enough to route it along the headliner and door seals of a midsize SUV to the rear window. They also include a trim removal tool to help you tuck the cable away cleanly without damaging your interior.
How does the parking mode work?
The parking mode uses buffered motion detection, meaning it saves footage from 10 seconds before an event is triggered. To use it 24/7, you must hardwire the camera to your car’s fuse box using a separate kit (sold separately). Without that kit, it will only record when the car is powered on.
Is the video quality worth the investment?
In my opinion, yes, especially if you need reliable evidence. The combination of 4K front, 2.5K rear, and STARVIS 2 sensors across all three cameras provides a level of detail that cheaper cams can’t match. I think it’s a worthwhile investment for professional drivers or anyone who spends hours daily on the road.
Can I update the dash cam’s software?
Absolutely, and it’s very easy. The camera supports Over-The-Air (OTA) updates through the Vantrue app. I updated the firmware in about 15 seconds using my phone’s Wi-Fi connection. This is great for getting new features and bug fixes without having to pull the camera down.
My Final Verdict
After testing it, I can say the Vantrue N4 Pro S is the most capable 3-channel dash cam I’ve used. The triple STARVIS 2 sensors deliver on their promise, providing excellent 4K+1080P+2.5K video that’s a cut above the competition, especially at night. I’d strongly recommend it to professional rideshare drivers and anyone who wants maximum coverage. I would not recommend it for someone who just needs a simple, budget-friendly front-and-rear setup.
The main limitation is that the full 24/7 parking mode requires a separate purchase. Despite that, I’d still buy it for my own car because the video quality and three-angle evidence are that good. For its intended user, the extra cost is justified by the superior performance.
Ready to Check the Price?
If you’re a serious driver who values top-tier video evidence from every angle, this dash cam is absolutely worth a closer look.
