Vantrue S1 Pro Max / Dual 4K & AI-powered / Dual SONY STARVIS 2 IMX678 Sensors / Novatek NT98529 / ADAS + BSD / PlatePix™ / Video and Screenshots

[Karagandinez]

I also received a new S1 Pro Max for testing.
Thanks to Wendy and the Vantrue team for providing the model.
I was in such a hurry to unpack and install the new model in the car that I didn't even have time to take photos of my copy.
Although there are plenty of photos in the "S1 Pro Max" thread. And not the kind I take, but professional ones.
And a lot of information about the S1 Pro Max has already been written.
The only thing I didn't notice anywhere was any mention of the processor installed on this model.
When I asked about the processor, the Vantrue representative replied that this model has a Novatek NT98529.

After installing the S1 Pro Max in the car, I immediately wanted to update to the firmware: VT-EEF243.
After updating the firmware, I decided to go for a drive to watch the purple video that I had seen mentioned in other threads.
But after viewing the footage, I did not notice anything similar.
I also saw a statement somewhere that PlatePix should not work without HDR, but on the new firmware, PlatePix turns on and works without HDR.
Or did I misunderstand something?
I need to reread all the threads on the S1 Pro Max to put all the information together...

I think i would prefer / not sure if that is how it was changed to.

Platepix = spiced up HDR, especially for night work.
And then maybe if it do not mess things up regular flavor HDR for the daytime.

I have been following these S1 PRO MAX threads too.

 

[Karagandinez]

Unfortunately, due to lack of time and reading in snatches,
I can’t systematize the information about different models in my head...
But I hope that I will make up for lost time.

If you want to see good photos of this model, I recommend you take a look at the topic located at the link below.
I hope the author of the topic won't mind me posting a link to his topic here.

Thread 'Reviewing and Testing the Vantrue S1 Pro Max'

Jun 22, 2025

Vantrue has been following an aggressive new product release schedule and I was recently invited by Wendy to review their brand new Sonnet 1 Pro Max. A big "Thank you!" to Wendy, @Jeff_Vantrue, and the Vantrue team for sending me this camera to review.

My other Vantrue dashcam reviews can be found here: E360, E1 Pro, N4S, S1 Pro Max, N4 Pro S, N5S

Don't mind at all, I'm rather flattered 😉. With so many great people here who have been reviewing cameras for far longer than I have, it's hard to find a way to make a contribution and stand out a little...

hi i want to know there are two pcs master chip nt98529 in s1promax ？

 

[Karagandinez]

You can ask the manufacturer directly about this.
They know better what is inside.

 

[indigo]

why s1promax 178m 1min

 

[TonyM]

why s1promax 178m 1min

Each channel is recording at 23.8Mbps, which equates to 178MB/min

too lower than 70mai m800
I don't believe s 1promax can see plate clear

 

[TonyM]

too lower than 70mai m800
I don't believe s 1promax can see plate clear

The S1 Pro Max is recording in HEVC / h265, so consider that if comparing to a AVC / h264 camera. But I agree, a higher bitrate would be nice if Vantrue can make that work reliably.

Plate capture seems to perform good out of the box from what I saw.
Can be compared to the E1 Pro.

 

[EricSan]

H.265 is (supposedly, up to) 50% more efficient than H.264 because of the variable block sizes (H.264 uses fixed block sizes) used when compressing the video. Both the N4S and the S1 Pro Max use H.265. The E1 Pro and E360 (and my Viofo A139) use H.264, so direct comparisons of bit rates and file sizes are a bit hampered. On top of this, the MPEG compression algorithm itself can be set for higher or lower compression rates (this is nothing new). It seems that Vantrue has chosen a somewhat higher compression rate to conserve on file size, helping the SD card to hold more recording time. I would prefer a bit less compressions for somewhat larger file sizes.

Having said that, comparing the Vantrue S1 Pro Max to the Viofo A139 (both use the 4k IMX678 sensors), I have found multiple instances of each camera outperforming the other in different lighting scenarios. There are very few absolutes here, which is a testament to the keen competition among brands and how they specifically employ image processing and compression.

I was expecting things to be more cut and dry, but that is simply not the case.

but why e1pro 1min 232m?

e1pro use h265 right？

 

[EricSan]

E1 Pro uses H264.

Sorry, left out the "Pro" designation when I described the E1 Pro camera above. I will edit accordingly.

so that mean the video of e1pro is most same as s1promax

s1promax bitrate is toooo lowest
