The list of shame fake 4K cameras and CMOS size

jokiin,
Tks for replying .
Would you please explain why is not a real 4K ?
 
I vote its fake, specs match my camera. You will likely get overly smooth 1080P out of it. Look at all that "fine" detail.

Some news:

The camera is like a sunXI tablet. I accessed ADB today after using phoenix suite to enter recovery mode.
It supports OV4689 and sony IMX179 according to the modules. The settings are simple config files and it uses the video4linux system https://en.wikipedia.org/wiki/Video4Linux

I have a system FEX but I need a img to update. At the very least I will try to edit audio to not be 8000hz, that is in simple config files like an android phone (media_profiles.xml)

ok, somewhat disturbing, camera.cfg lists nt99141 (a cheap 720P sensor) but its using the imx179s driver that claims the 8mp... so I dunno. I'm an engineer and I can't figure out what are lies and what is truth 🙁

Here is what happens and why video quality is so bad:

<5>[ 943.659551] [VFE]width_input = 3168, height_input = 1792, width = 1920, height = 1080
<7>[ 943.668405] [ISP] full_size width = 1920, height = 1080.
<7>[ 943.674438] [ISP] scale width = 640, height = 360 <this is preview lcd

for 2k/1080P/4k the full sensor size is scaled according to VFL then the nasty post processing is applied. This camera would be fine at these resolutions if they left alone what was there.

Partition structure:

Maybe this will need a new thread.. but where?

Hello !
Here is what the seller says in Aliexpress message about this article and comments:
Citation:
"
This is ridiculous, this article's author is obviously sjcam sent to write this article. This is like, hire people to say Samsung Apple phone, the phone is not that Apple 8-core processor and no better than the Samsung mobile phones.
This is a very funny thing, different prices of different brands all have different effects of different needs. If people buy a Samsung mobile phone, he would not buy a Samsung because someone malicious words.
If I use a Samsung mobile phone is useful, I do not care how people say Apple and Samsung, I feel is the most important. If we live in someone else's words, it is not their life.
"
If were a response to you What would you say to this seller ??
( he already as my money but I can complain or not I just want to be fair , for me the honest and fair thing accepted is
to have what I bought with the features written in the description ) .
 
If someone sells you a saemsump or a fapple as samsung or apple then that is called fraud. If they put 8 core in the description but processor is 400mhz and out of a linksys router you have a right to complain. Even besides the fake 4k, if 1080P isn't real there is a serious problem.

You mean the Coby stereo and VCR I own aren't actually made by Sony???? 😛

Lol@"fapple" - that IS a very fitting name at times

Actually Coby had been around for 19 years before they went broke, the font was very Sony looking though

They are still in the market but only in name, someone bought what was left of the company a few years ago and just puts the name on anything they can these days

I had to update 7zip but indeed it does! If I had known that I would not have a softbrick right now.


So I looked at replacement cameras if they completely refuse to give me a recovery method or I can't figure one out. Everything costs more than $60 USD.... BEWARE: Real 1080P is as hard to find as 4k. They are using 720P sensors in cameras too.

But you need an IR cut filter, otherwise must colors are "pinky"

What is the real resolution of these fake 4K lenses?

Hopefully they are good for 1080?
 
Does anyone know if any of these fake 4k cameras come with gyro stabilization under $70?

I think the gyro sensor is one of the most expensive components and it also needs a fairly powerful processor to manipulate the image, plus it doesn't work well with low resolution sensors like most of the cheap cameras have. I think it is unlikely that you will see gyro stabilisation for under $70 for some time yet. However for about $100, you might pick up a Gitup Git2 which has one of the best gyro stabilisers currently available and is well worth the extra just for the gyro stabiliser. Also note that some of the cameras that do have gyro stabilisers don't do a very good job of stabilisation, it is not a simple task to get it working with a new camera.

I don't think any of the real 4K cameras can gyro stabilise 4K video yet, even if they have a gyro stabiliser that works at HD resolution. Even if they could, most don't have enough resolution to produce real 4K gyro stabilised video, a 12MP sensor is not enough.
 
Thanks for the replies, and yea i dont need actual 4k stabilization, stabilized 1080p is fine for me. I actually saw the sj5000 on gearbest about a week ago for $73, i should have bought it, but i didnt know much about cams, thats what made me start researching but now the sales over.

@action camera, did you post that saying its gyro stabilized? i think that one just uses electronic stabilization, which was actually my next question, do any of them do a decent job with electronic stabilization? Mainly going to be using it to strap to airplanes.
