Vantrue N4S - 3x STARVIS 2 IMX675 with Waterproof 2.5K Rear camera - Unboxing & First Impressions Europe

[Julian23]

The N4S has been running solid ever since it was installed.
It did not have any issues.

Additionally, the suction cup mount has been very solid. Not once did it lose its suction.
Temperatures ranging from -5°C to 37°C had no effect on it at all.

I can only recommend it.

Temperatures ranging from -5°C to 37°C had no effect on it at all.

I can extend that temp range: -15c to 37c outside ambient temps. No issues at all, both the camera and the suction cup mount are excellent performers across a wide range of temps.

Nice to hear that it works fine for others as well.

I was a bit worried about the suction cup but it has proven itself so far.

I received the new Vantrue RC18 rear camera that is compatible with the N4 Pro S, N4S and the S1 Pro Max.
This model is NOT waterproof. It is intended to be mounted on the inside. This proven design should remove any unwanted movement that could be found with the RC09.
Here are some pictures of the RC18 next to the RC09 that is included with the N4 Pro S, N4S and the S1 Pro Max in the 4k + 2.5k version.

The new RC18 does not have an extension like the RC09 has. The cable from the front camera plugs directly into the RC18.
The RC18 can be rotated 360° to allow installation in any location.

On the rear of the lens are two vents to remove any heat. Next to the vents is the status LED.

Size comparison:

I will install the RC18 in the next few days and share some footage from it.

The RC18 is expected to launch in March.

I have been using the RC18 rear camera for several weeks now as a replacement for the RC09.
It has performed flawlessly without any issues.

The most significant improvement is the physical stability of the unit. With the RC09, there could be some visible vibration depending on the mounting method. This is no longer an issue with the RC18. The mount is very firm and the camera does not wobble at all. The tube-shaped camera will also blend in a bit better than the RC09. Hiding the cable is also easier with the RC18.
Regarding the image quality, it's similar to the RC09. I am particularly impressed with the edge-to-edge sharpness. Even at the corners of the frame, the clarity remains very good, and license plates are easily readable. This will of course depend on several other factors like speed and lighting, but overall it performs well.

I will post some pictures in the coming days to demonstrate this. For now, I can say that the RC18 is a solid improvement in terms of mounting stability.

Here are pictures from the rear camera.
Please note that the weather has been less than ideal. Only little sun and very cloudy.
The rear windshield is also sometimes dirty.
All this makes it the ideal test for the RC18.

Slow speed with car behind:

Left car stationary, right car approaching.

Car on the left passing with about 50km/h speed difference, right car following closely.
Both plates can be read.

A different plate from the Netherlands:
The plate from the car behind can also be read.

Very good sharpness near the edge:

City traffic:

Plate of the car behind can be read. Car in the other lane not.

Plate from the car on the right can be read.

Here are some more:

Very crisp plate in a darker environment.

Some plates in a traffic jam and good capture near the edge.

As shown in the pictures, the image quality is very good for a 2.5k rear camera.
It will capture most of the cars traveling in the same direction as long as there is a certain amount of light.
The sharpness near the edges is good. I've seen other cameras struggling with this.
The image quality is not really different than the images from the waterproof RC09 version. (This was to be expected)

The barrel style design definitely helps to eliminate vibrations, which will of course improve the image quality.
If you don't need the waterproof camera, wait until the RC18 is released.
