Viofo A329T (unboxing & first impressions) (Sony Starvis 2 IMX678, Wi-Fi 6/GPS, HDR, Novatek NT98530, 4K front + 2.5K telephoto + 2.5K rear, HDR all)

IMX585 or IMX835?? 4K 1/1.2" with 2.9um x 2.9um pixels

Oooo-la-la. Just found the following chart after you posted some sensor numbers. Since none of the websites I just found have any dates on them, it is unclear how "new" some of these sensors are. Sure, a wider sensor means a larger chip, which needs a larger housing, and a larger lens with a wider physical aperture, so I assume costs will escalate rapidly. I wonder who will be (or is already?) first to use the IMX835... A quick search didn't indicate any dashcam use for this camera yet... That looks like it could be a game changer, especially for low-light situations!

I have a feeling from memory that IMX585 is the first gen Starvis i.e. IMX415 that was used a fair bit in dashcams as 4K, IMX835 is Starvis 2 generation. Guessing due to cost that none of these higher end sensors were used in dashcams, perhaps in security cameras applications only..
 
That's my guess, too. I'm thinking this would push production costs up quite a bit and with present flagship cameras coming in at the $500 mark, there may be little appetite to use more expensive components at the present time. Maybe costs decline in a year or two...

Just googled and I was wrong haha, imx585 is Starvis 2 just that imx835 was a newer Starvis 2 improvement on it.

Looks like the imx585 was used for astro cameras, so that's interesting. Maybe higher end applications for these kinds of cameras. Don't see why vendors can't use them in dashcams at some stage, unless they never come down in price (even if they have been out for a few years)

I was careful not to suggest the older 4K STARVIS 1 option - the imx485.

There didn't appear to be a big jump in sensitivity between the 1/1.8" sensors and the 1/1.2". I wonder if any manufacturers have tried the larger sensors.

Did you click on each one to read the sensor spec sheet?

Hmmm... that page doesn't seem to have clickable links for me. Are you working for somewhere else? Spec sheets are fun!
 
Ha- same chart, different source 😉

I did read a spec sheet for the 678 at some point. In addition to larger pixels, the 835 seems to have greater sensitivity by about 20% (unless I'm reading that incorrectly) and a higher frame rate, but is otherwise quite similar.

IMX835 is almost same as IMX678, just a rename and to make it can pass the US import policy.

There we go, we have an answer from the maestros themselves 🙂. Most cost effective solution is to go Imx678 then

There is so little in the context of policies lately that doesn't make me just put my head in my hands and wonder, "huh?" ...:facepalm:
Sigh...
 
Another follow-up video comparing the rear cameras of the Viofo A229 Ultra, Viofo A329S and Vantrue S1 Pro Max.

Very interesting to see the A329S absolutely nailing the daytime licence plate captures, even though it's 2.5K resolution and not 4K resolution like it's competitors!. At night time all three cameras perform well though.

The IMX675 is still a good sensor, sometimes better than the IMX678.
The S1 Pro Max is suffering because of its poor mount design causing noticeable vibration. I see in the YT description that the camera was mounted externally.

True about the imx675, remember seeing somewhere in the specs it does better at a thing or two over the imx678 so makes sense. Also have to wonder with the lesser processor on the A229 Ultra, plus product differentiation comes into play - would make no sense for that to perform better than the A329S series...
