Review : 4K + 4K - Vantrue S1 Pro Max

ADAS on the S1 Pro Max

A short test to see if I can record the on screen display with AI frame overlay whilst driving, to capture both the audible and visible alerts.


The AI is good at identifying cars. It didn't recognise the cyclists, although that's a difficult test since they're not using any lights at night 🙁

S1 Pro Max set to PlatePix OFF and HDR ON

This was a quick edit to see if the compilation looks OK before I get stuck into recording more examples both day & night.
 
Cyclists ahead is too stupid
 
Blind Spot Detection on the S1 Pro Max

A short test of the Blind Spot Detection function on the S1 Pro Max, part of the Vantrue Intelligence AI feature set on this new dashcam.

The inset video shows the Vantrue Intelligence on-screen display option, without the AI tracking rectangles shown in my previous video. The screen switches to live view when I press the Event button to save the video clips.


The BSD function requires good subject detection from the rear camera. It did quite well here despite the wet rear screen, and I was surprised how quick it responded to the BMW's lane change.

I think it helped that the cars behind me had headlights on - an hour earlier in the day the BSD did not pick up some cars that were not using headlights.

Both cameras had HDR enabled, the clips were recorded just after sunset
The front camera had PlatePix OFF (not available for the rear camera)

It does look like there's some dropped frames and you see this periodic stutter. The E1 Pro did something similar at launch. Looking at the YouTube video stats, I'm not seeing dropped frames on the playback side, so I'm assuming it's on the capture side.

I just noticed this today as I was doing some frame-by-frame analysis of the S1 Pro Max. It wasn't super consistent, but it did show up here and there.
 
@TonyM - That's a very nice comparison of HDR and PlatePix for the night time scene. I've been playing with these settings and struggling with which one I think works better at which time. I live in a relatively sparse area, so there isn't much night time traffic for me to play with. I also like that bracket you made for capturing the display of the S1 Pro Max - very clever!

Whilst the E1 Pro initially had dropped frames (now fixed) the S1 Pro Max does have a full 30 frames / second, but the timing varies such that intervals between frames are sometimes more or less than 1/30s/. I'm not sure if there's software capable of analysing this? I suppose I could record a stopwatch and measure the intervals...

Hi, yes there were duplicates, Vantrue already knows about it and is working on a fix, we are waiting for a new firmware.

The only way that I have to analyze this is by using a free version of CapCut and then stepping through the footage frame by frame looking for successive, identical frames, or "gaps" that seem to indicate larger than normal movement between frames. This gets a little tedious, though. I found only 2 instances of the S1PM doing this across several files, but I haven't spent a large amount of time looking because the overall videos look nice and smooth.

With the E1 Pro, jumps in the video were much more obvious, but recent firmware has corrected this issue.
 
ADAS & BSD Observations

The AI seems to be smart enough to tell the difference between the front and rear of other cars, since ADAS on the front camera only tracks the rear of cars when computing their position and deciding when to sound an alert.

Here's a photo of the on-screen display with AI overlay whilst I was parked. Note that only the cars facing away have red rectangles around them.
Note: ADAS and BSD do not work in parking mode. I was parked, but the camera was in Normal 4K+4K recording mode at the time.

The black car in the middle is parked directly opposite and I have carefully aligned the camera to look straight ahead, so the distance to the silver car to its left and the red car to its right should be the same. However the overlay suggests they are 20ft and 27ft away, so the calibration is not perfect. The right side of the image does appear to curve away more than the left - I think that is due to the windscreen curvature rather than the dashcam.

By way of comparison, Blind Spot Detection on the rear camera identifies both the front and rear of other cars, apparently even through the plexiglass shopping trolley enclosure.

Again the actual distances appear slightly inaccurate. In this example the red rectangle has missed the lower edge of the white car behind, so it thinks that car is further away than it is.
 
Wow -that's pretty cool - I'm especially impressed that it picked up the second row of parked cars (even between the black and white cars in the foreground, and as you point out, two of them are read through the plexiglass canopy!

Parking Mode Delay Timer

@Jeff_Vantrue is it possible to add a firmware option: A delay timer for entering parking mode? The options could be Off, 1min and 3min after turning off the ignition. I remember my previous Viofo dashcams had this option available.

The reason for the request is that in collision detection mode the S1 Pro Max registers an impact every time I close the car door, which is great for detecting incidents so I don't want to turn down the sensitivity.

However, when connected to the LTE module I get an event notification on my phone every time I park the car and close the door, and the camera uploads 180MB of video clips. On a regular driving day with a few stops at work, grocery stores etc this can easily add up to 1GB a day. This seems an unnecessary waste of data, and after a few days of use I'm already getting a warning that I'm running out of data on my SIM card. My Vantrue Cloud folder is also full.

This firmware request also applies to your other LTE-enabled models.

As an example, the S1 Pro Max uploaded 720MB of data yesterday:

Yes, I was wrong with my previous statement. I have since reviewed more videos and found duplicate frames.

It's a Mobius 1S with a 6-22mm varifocal lens, mounted on a Smallrig 5" magic arm with super clamp around a headrest post

This video was shot on a test firmware. There are no duplicate frames in it.

I hope that we will receive a new, corrected firmware in the near future.
 
@TonyM

However, could you do a similar test at dusk and dark with HDR and PlatePix. I noticed on the N4 S Pro you did get ghosting with HDR. I assume that's normal due to the longer exposure times and the need to capture multiple images (three) in order to overlay them for reading license plates and signs.

I'm doing bug testing on all the units I've received first, so haven't had a chance to really test out all the features at great length. I figure, there are plenty of people handling the reviews, so I wanted to focus on reliability and stability.

So does the S1 Pro Max suffer from dupe frames... Not Noticing any Stuttering on my Video with latest firmware? Any issues on N4 Pro S? What about N4S? I hadn't gotten that far yet on video. I am checking cameras for stability and reliability per my other responses in threads.

I am seeing duplicate frames on the latest public firmware. I do not have the test FW that @Karagandinez is testing, which appears to have fixed the problem.
