Just don't bother

Yes, I will take care of this case. Thank you for the support!

I just sent you the message.

Please trust me that we are willing to fix the issue, and would like to work with you to make the products to be even better based on your knowledge and support!

@Rock Liu thanks, I've dropped you a reply, happy to help out and especially keen to see if we can get to the bottom of the network issue.

@nullpacket

We respect all customers' feedback and happy to discuss together for improvement.

I build and run large scale, bleeding edge container orchestration platforms for a major cloud provider for a living. Technology isn't anything new to me.

Glad to see you have rich knowledge on this area, indeed, we have been thinking about to add 4G network to the camera system, and build up the platform like home CCTV for individuals checking the live stream at home, or the traffic police department to manage the cars / motorcycles on the orad.

We need to learn more if you are willing to support.

About the problems raised, please see below,

1. WiFi & 4G connection conflicated problem for Android system, we are still on the study stage and find the way to fix.

2. K2 camera issue & Customer support by email communcation, There is the simple rule we followed, if the problem could not be fixed, we will send you new one. Email, address, phone number, those private information are required for the delivery.

As you can see we are a small team, but never have an excuse for refusing to do the best customer support and product improvement.

@Rock Liu I was just having a look at the routing table.

The first ip route shows the default route via the mobile data interface. All looks good here.

The second ip route command shows the default route after connecting to K2 with mobile data enabled, here we can clearly see there are two default gateways, the original route for the mobile data interface and a second on the wifi interface.

The third ip route command there shows the static route for the 192.168.1.0/24 network over the wifi interface.

It seems like this might be your problem, I wouldn't expect a network without internet access to advertise itself as a default gateway, I would simply expect to see the static route for the /24 via wlan0 and the default gateway via rmnet_data2

My device isnt rooted so I can't manipulate the routing table to see how it affects things.

This makes me interested in the DHCP servers configuration though. I'd be looking at setting dhcp-option: 3 which should prevent the DHCP server from pushing a default route to dhcp clients and/or push a static route, something like...

That's just off the top of my head so may not be totally correct.

So the Wifi is not suitable for that, then why is the option even in the app for downloading the content and why did they change the app from allowing only a single video file download at a time to being able to select multiple downloads, clearly it was expected that users would want to download the content over wifi.

The option to mark several videos at once in the app has been added due to customers requests. Some of them wanted it for downloading multiple files at once (they really seem to have time), but mainly to mark files for deletion. And you have to take into account that the App is also used with the K5, which wifi is twice the speed. Which is, of course, still way to slow to download a complete road trip.

So yes...you are right that wifi is bloddy slow and the only pratical way to download the videos is to remove the SD Card. But after reading the specs (which I assume you did before buying), you did not expect the 2.4GHz wifi to give you a high speed download, didn'you?

The wifi is for setting up the camera and streaming the saved videos from the camera to your phone. That's it. Downloading is possible, but....aehmmm...yes. Let's stay at "it is possible".

Irrespective of where the DVR is located, it's a PITA to get to the microsd card out and lets not forget, we're fitting this to bikes where in most cases, space is limited. Perhaps not if you ride a huge tourer, but not everyone rides that class of bike.

Did you try to use a sd card extender? I never used one, but maybe it could help you accessing the sd card.

On the live feed topic, i'd guess it's an mjpeg stream much like the cheap home CCTV cams and I'd bet that if I point VLC at that stream it would work fine. None of this is new tech, it should just work.

Yes. You can simply use your browser or VLC to stream the video.

I did this at my test K2 for hours and it worked without issues. If it does not work for you, I would guess it has something to do with your phone (very unlikely) or the App (most likely). The live view was never intended to be used all the time while riding, but to check/adjust the cameras. It could be that the developer of the app has been a little bit sloppy, so that a buffer overrun occurs after a while. Maybe you want to test it using the browser or VLC.

I was just having a look at the routing table.

I wouldn't expect a network without internet access to advertise itself as a default gateway, 

Interesting finding. I don't use android, so I wasn't able to check the routing table. But that could really be the reason why the app does have problems at android.

I guess the developer of the firmware simply uses the DHCP server with its default configuration and has never heard about DHCP options.

@Rock Liu You should let your engineers/developers check this.

And today, as I almost got wiped out by a tractor, I went to grab the video and guess what? Corrupt. 
....
Now let's discuss your comment "if it shakes too much, the recordings can become corrupt", that's poor design and build quality, again these are designed for use on motorbikes which make for a harsher environment than say a dashcam fitted in a car.
...
Maybe there's a recent firmware update to solve some of these issues... wait, no, nothing since 2020.

I've read about that issue in the forum two or three times. And I am quite sure the source of the problem is an inaccuracy in the sd card slot and/or the sd card.

If the slot is slightly too wide (and we are speaking of 0,1mm) and/or the sd card is slightly too thin, vibrations can lead to a bad connection and the MP4 file gets corrupted.

I agree with you that these inaccuracy should not happen. But as this is a rarely issue (at least to my knowledge), the only thing you could do is trying to fix it. You could test a different sd card or try to make the card a little bit thicker.

At the software side, I would suggest to switch to TS format. Not only because of the vibration issue you have, but also to prevent corruption in case of a power outage.

Let's say you have a decent accident and the power to the K2 gets cut off. In that case the MP4 would be corrupted, too. That's why I switch over to TS, which is more robust in that cases.

And lets also talk about why Innov are asking people to email them to discuss issues rather than having an open discussion on the forum where that benefits any existing users as well as potential buyers as well as avoiding duplicate queries etc? 

At first glance one could think that this is to prevent negative posting in the forum. But it is more a common behaviour of companies to give customers an individual support rather than doing all in public. Just because most of the customers prefer this way.

There are many open discussions in the forum about issues. I can think of the power drain issue, the plastic connector issue, the power module temperatur issue or the bitrate issue. None of them were all positive to Innovv, but has been solved at last.

So no...they are not trying to hide your problem from the forum, but instead want to help you.
