ALL Dash Cams Have Distortion- "Bending Images"

[synoptic12]

Mentioned the Mobius because it has a lot of end user adjustability in the setup to fine tune the results, from what you described so far it doesn't sound like you really want a traditional dashcam type product

Had to look up the Vinsloo, had never heard of it, seems they are just a trading company, the models on their site are all public models, the 650 is a knockoff of the HP camera from Taiwan, lots of small factories do these models, what's inside or where they source them from is anyone's guess

There are only 2 foundries I believe. H.P.'s cam is a little pricey, about two bills. The 650 is only 88. You are a manufacturer, provide something for me, or suggest what you have available. Thank you.

the problem with this is that your own undistorted field of view is much wider than that of a camera

35mm is very narrow compared

I'm not sure what you mean by 2 foundries???

I've suggested all I can think of at this stage

I was going to suggest the Mobius as well, since the A lens has very little, if any barrel distortion. Most dash cams as you noticed lean towards wide lenses. I will disagree with you on the heat issue, which never resulted into anything. I believe you can research this also on the RC group Mobius page which is very long and not find any heating problems.

Is loop recording important, mounting location or size swaying you from a full size camera?

I was ready to purchase the Mobius until I saw a video on YouTube where the cam was virtually melted from heat. When I first viewed the Mobius video, it appeared outstanding. A Englander provided the footage via YouTube. As I moved to investigate further (Dash Cam Talk), there were inferences as to heat issues. Cannot take any chances with heat being a factor. "Heat' must be the most important aspect to overcome, and a key factor in obtaining a good product. The Mobius runs hot, for there are sufficient responses to warrant a verdict. Naturally, the Mobius page will not dictate the faults of the unit, not many manufacturers will,.

All cameras incorporate loop recording, if they did not, what would be the purpose of a dash cam? Can you elaborate on a "full size" camera?

Foundaries are where the circuit boards, transistors, diodes, etc. are made. There may be possibly three. Know that 2 are in China. What do you manufacture?

Yes, it is, but the end result is 'outstanding'.

Hello everybody ! Reading this forum day by day , I have observed that there are few dashcam potential "consumers'' which put the ,,nondistorted'' images/video in top preference . I am one of them - as synoptic 12 . It would be ideal to record the reality as it is , and dashcam present today on the market could fulfill both goals : witness of unpleasent event and memory of beautiful landscapes (with less or more compromise , because of optics ) . This thing doesn't mean an exaction ! How to install and manipulate an expensive proffesional camera when driving , in order to make for an ideal movie ?? As I said , few present dashcams could make this ! This is the reason that I refuse some of the best dashcam - Panorama , and others , because of its fisheye effect . Instead of it , I put about Transcend DrivePro ( I am waitig one ) , Mobius A lens ( I have one and is remarcable ) and maybe new arrival Innovv C3 (all with capacitors ! ). It would be G90 . So , to ask for a dashcam that could record the reality without MUCH distorsion is not such a out-of-the-way wish !

Thank you very much. Does the Mobius have capacitors, or the C3 which I have no knowledge of? What of the heat issue with Mobius?

Where I come from foundries do metal casting, PCB manufacture in China, there's thousands

Thank you very much. Does the Mobius have capacitors, or the C3 which I have no knowledge of? What of the heat issue with Mobius?

Irrespective of the foundary issue, I was looking at the INNOV C3 which seems to be o.k. The unit employs the Alpina AR0330 and Novatek 96650 which many cams employ. However the lenses are exchangeable; 145 mm and 120 mm I believe. Outside of the lenses, what would make this unit perform better that other dash cams which have the same components?

The new Innovv C3 will have a model with capacitor , as I know from Niko review.

P.S.- There are only (three) 3 foundaries that produce 'computer' components.

Thank you for that information. If you notice my previous thread, this C3 incorporates the Alpina AR0330 AND Novatek 96650 which many cams employ. What would make the C3 different, aside from the interchangeable lenses (terms of quality video)?

not sure which components you are referring to, vague references don't help to understand, raw materials may all come from limited sources but it branches out from there

for reference when you see the spec listed these lenses are listed by diagonal degrees of viewing angle, not mm, because it's diagonal though it makes it harder to compare products as the vertical and horizontal angles may be quite different between two models that list the same numbers

Forget the foundary issue, Don't wish to discuss manufacturing. I understand your meaning regarding the vertical and horizontal measurement. Are diagonal angles more exact as opposed to North and South, so to say? This seems to be a company ploy to distract, or divert one's attention away by misleading the consumer. I may have heard reference to this, but paid no attention. Exactly what is the difference in diagonal degrees as opposed to vertical and horizontal views? I believe that one of our televisions (Mitsubishi) has correlated diagonal lines to adjust. I really have no notion as to which is more efficient. The measurement is taken at the corners, rather the vertical or horizontal. Naturally, I've been blindsided with millimeters as being a standard of measure. (cameras)

Aside from meaningless diatribe, what do you think of the INNOV C3, and, or Mobius (heat issue for sure)? Can't stay up much longer. Thank you.

From this forum opinion , Mobius (with battery ) has not heat issue , as few well known members said .

I've seen the video on YouTube where the cam was 'melted' by heat. Can't find the link right now. Anyways, thank you very much, as well as the others which assisted. Going to sleep.

Ambarella have a function in the firmware that can dewarp the image specific to the lens spec used, not too many using it as yet as it's still relatively new

The distorted view is a result of the lens type, that's just physics, a narrow lens wouldn't suffer this issue but then it also wouldn't make for a good dashcam solution, there are always compromises to be made

It's more a result of the sensor chips being flat with a rectangular grid of pixels instead of being matched to the image produced by the lens. Having collected the data from that rectangular grid of pixels the only way to get it straight is to reorganise the pixels in software which has to result in a fair amount of real data getting lost. Throwing away data from a dashcam image in order that the image looks straight instead of warped doesn't make sense as that lost data may have been useful, better to leave it warped, you can always dewarp it later on your computer. Having said that, the next generation of sensors may well have far more pixels than get recorded in the data stream thus allowing data to be lost during dewarp while still filling the full bitrate.

not at all

what do you think of the INNOV C3, and, or Mobius (heat issue for sure)?

Haven't seen the C3 myself, I have a C1 and it works well, I feel Innovv have enough resources and experience to get good results from the C3 so expect it should be much the same performance wise, just a different form factor

I've seen a couple of reports of heat issues with the Mobius, keep in mind they've sold 20,000 or so, given the numbers I would say heat related issues are the exception rather than the rule

I'm unaware of the information you presented, but understand the synopsis fully. It stands to reason that pixelation is the main ingredient on rendering video. To correct video footage using the process to 'dewarp' is unfamiliar to me. This would be more work, using the time in correcting faults. Not that I wish to delve upon litigation; but editing,or re-editing video would not suffice in presenting evidence in a court of law. Now, you may have a clearer picture on the end result we are trying to achieve.

What would you suggest, or advise in a dash camera? In your writing, I can notice that you may be from England by certain wording you use. I have acquired some very good information from the 'Brits', more so than in the U.S.
