Here are some stills comparing A119 and mini 0903 (with CPL) Images resized because of forum limit.

Yeah you cant UL too large files directely to the site, but photo linking to large pics offline should be fine.
I usioally use a Danish file / photo share site, if i would i could link here to a 22 MB RAW photo from my nikon, but it would only appear as the regular "large! picture here and then go to ( redirect in some way i assume ) to the full 20 or whatever it is megapixel picture.

BUT ! i don't do raw photos as i don't do post processing cuz i think that's cheating.

It's weird because the forum says max image size:

Upload a File (Max 5 MB):
Accepted file types: zip, txt, pdf, png, jpg, jpeg, jpe, gif
Max image width: 2,560 pixels
Max image height: 1,440 pixels

My image (raw from VLC) was 1920x1080 (2.5MB)

The A119 appears to be fuzzier overall. In the shot with the Willis sign, the mini 0903 is noticeably sharper on both signs. But it's noticeable in the other photos as well. For example, the one with the right turn only sign is easier to read with the mini 0903 than it is with the A119.

I may be wrong, but it seems the shots with blurred left side seem to be focusing on the "black dots" on the top right of the image (with the exception where there are trees, as I cannot see them in the foliage). Perhaps a focal point issue? Maybe try turning the lens to avoid those black dots and see if the issue resolves itself?

if the mini 0903 can do that well, so SG9665GC will do much more better. :)
what's a pity ! every product of Megtech has a pretty good image quality but not reliable.

Little unfair to compare the A119 without a CPL against a dash camera with a CPL. The color saturation the CPL adds can be dramatic, like those photos. I think the reflections can be distracting and make the picture "appear" worse as well. Maybe compare without the CPL?

The 0903 has an advantage of a narrower FOV so as long as what you want to see hasn't fallen off the side of the image, it should have more detail. I find it a bit too narrow, some things I want to see are off the edge when they would have been visible on the 0806, A119 seems to be a compromise between the two.

The 0903 also has the advantage of a more sensitive sensor which results in less motion blur in the higher speed images, need the A119s to match that.

Also , the 0903 appears to have a working CPL in these images and that makes the job of compressing the video easier when there is a lot of movement so more detail can be stored.

I also think the left side is a little out of focus. If I wanted to refocus, how would I go about connecting A119 to HD monitor? AFAIK, there is no HDMI - can A119 function as a web cam?

Can you redo the test without CPL in both of dashcams ? :)

Interesting ! And i have some picture of side by side SG9665GC and mini 0903. What's a pity ! i dont save raw video and my 0903 mount was broken so i can't redo the test.
PS: Two of them both dont have CPL filter.


First, at high speed





a static sence.




SG9665GC is better than 0903 in day and night.

How did StreetGuardian end up in this thread?
I count at least 3 threads asking about comparing between 9665 and 119, maybe because it has the same form factor ? I am pretty curios about 119 and don't have one. But if i don't have full video, so it doesnt seem right if i make a new thread, is this right ? So i post it in here, hope you don't mind ;)

Removing the CPL didn't change anything. The mini is still much clearer than the 119.
If I could get the mini 0903 guts in A119 body I would be a happy camper :)
To tell the truth though, most people will not get the result from their 0903 as shown here.
I thoroughly cleaned the lens front and back as well as sensor and then reseated it and refocused.
It seems 0903 has a better lens and sensor so A119 eeven with double the pixels is still not as clear.
Not sure if @viofo will be able to improve it in software.

yeah, my 0903 cost me a lot of money and you can see: in the 3rd and 4th pic, my car was stoping but velocity in 0903 was 8 km/h. :rolleyes: Plastic mount, GPS, and housing is weak point of this model.
