Vantrue N4S – Triple Channel STARVIS 2 Dash Cam w/ IP67 Rear Cam – Hands-on First Impressions

[viciouslancer]

I’ve been using Vantrue's new N4S 3-channel dash cam for a few weeks now. I wanted post some first impressions for anyone who’s curious about how it performs, especially compared to other triple-cam setups.

So far, I’ve been pretty impressed with the overall video quality—it uses STARVIS 2 sensors on all three lenses and records in 2.7K front, 2.5K cabin, 2.5K rear, all at 30fps with HDR. I’ll include YouTube links below with sample clips from daytime and nighttime for both front and rear - I'll try to find some good angles of the cabin and post those later.

Install & Mounting Thoughts​

Physically, the camera is definitely on the larger side, especially compared to my old Vantrue N2S. Finding a good spot on the windshield took more effort than I expected. Since it uses double-sided adhesive instead of a suction mount, it’s kind of a one-shot deal—once you stick it on, repositioning is tricky unless you want to break out another adhesive pad (well, maybe the electrostatic sticker can be repositioned, I didn't want to try).

The field of view is generous, so you can technically mount it almost anywhere. But the tricky part is avoiding your rear-view mirror when trying to get a decent cabin view. Just something to consider if you’ve got a tight windshield layout.

Rear cam installation was pretty smooth—the cable’s long enough for most vehicles, and the included seals made it easy to route discreetly. I mounted mine inside on the rear window, but with 20% tint I’m definitely seeing some darkness in night footage because of it. The rear cam is IP67 rated, so it could be mounted externally (likely very good for pickup trucks, cargo vans, and the like), the problem is I'm not sure how to keep it clean in rain and snow.

Video Quality​

Overall, the video quality is impressive. The N4S captures clear, sharp footage during the day, and license plates are readable even at a distance. At night, the front cam does a great job adjusting for glare and headlights, and thanks to HDR, details don’t get completely blown out or lost in the shadows. Rear is decent too but I couldn't make out plate details at night, through the tint.

WiFi & App​

The 5GHz WiFi makes file transfers quick, which is nice for large files at high resolution. I’ve had no trouble connecting to the app so far, and navigating is the app is fairly straight forward. I haven’t tested the LTE module yet (sold separately), so can’t comment on remote alerts or cloud features.

Parking Mode​

I wired it into my fuse box using Vantrue’s hardwire kit, and have it set to 15FPS parking mode. So far it’s worked well, but I still need to try out the other modes - it could help with storage space and battery life, but more importantly, it'll help identify any movement instead of just a constant recording with no flagging.

Sample Footage​

Here are some YouTube clips showing the front and rear cams in action. No cabin footage yet.

Closing Thoughts​

Overall, the N4S has been solid. Great video quality across all three channels, flexible enough installation for most cars, and the waterproof rear cam is a nice touch - especially if you want to avoid filming through rear glass. The form factor and adhesive-only mount do make initial placement a bit stressful, and the rear cam footage is definitely impacted by tint (as with any camera) if mounted inside.

I’ll keep testing it over the next few weeks and post more updates or footage. Let me know if there’s anything specific you want me to try out or test.

If you don't pursue the ultimate picture, n4s is enough. I have used n4 before, and n4s is much clearer than n4. What I am most dissatisfied with is that n4s distorts the video playback at the highest resolution, so I have to set the resolution to 1920 * 1440

The N4 Pro S resolved this concern. It runs 4K without distorting the image to a 4:3 aspect ratio. I only got front camera installed, not yet done the rear camera. If you are inclined, it looks like the S1 Pro Max (4K front + 4K Rear) or the 3 Channel N4 Pro S will be Vantrues' new flagship models.

I suggest using the CPL filter on the front to eliminate the glare.
