@joseph_1979 to add to this, my phone works fine using the highest frame rate, bit rate and resolution using the rtsp stream via VLC. The problem is though you don't have the talk back feature hence why I am trying to raise awareness of the issue and get it fixed.

Hi @joseph_1979, from experimentation, I've learnt that resolution and bit rate on the high and low quality stream doesn't have any effect, it's in variably the frame rate that impacts the audio.

PS how do you earn reputation points? I can only reply every half hour

Some pics (wouldn't let me include them in the previous reply! I think it didn't like inline images rather than inserting from a file and now it's told me I have to wait 600 seconds and now 1800 seconds before adding another post as I don't have enough reputation points! )

These settings stopped the phone stuttering at the expense of recording frame rate which i fear may also impact the NVR - can anyone confirm that ?




Thanks

@joseph_1979 thanks for the reply, I have access to a huawei media tab 2 and that shows the same issues. However I have just asked a friend to trial it as they have a brand new moto g23 running android 13 and it looks like it's fine on that, so it's not just my phone, but could be something due to older android versions? Memory is not an issue on my phone. 700-1.2gb rom memory free.

Any thoughts

Hi All,

I have an update... By reducing the frame rate (via the web user interface of the camera) from a default of 20 for clear and 15 for fluent down to 4 or 6 respectively, the audio no longer stutters, so that's great new, however this is detrimental to the video frame rate that you view on the phone but at least you can actually now here the person speak clearly now. Would this setting also stop full 20fps or 15frps recording on an NVR if I was to buy one?

On a technical front, changing the FPS will amend the encoding process on the camera I suspect. Some other devices (i've borrowed) have been fine at higher frame rates - even at the max) so do you think this might mean a problem with the encoding (ie camera firmware) or decoding (a combination of the phone and app)?

Changing the birate has no effect it seems, changing to the lowest quality or leaving it on the highest settings makes no difference. However, disabling the hardware decoder setting on the App on my phone does cause the audio to stutter again, even at the lowest frame rates.

Please could someone advice what this might mean (as technical as you like as I will plan to forward this to the engineers in hope that can make a change).

Thanks

Rodp


Key points: (unable to paste images in!)
Fluent mode: On the web user interface, by increasing the Frame Rate setting from either 4 or 7 to 10 or 15, the audio starts to stutter on the phone app.
Clear mode: When I am using the App on High / Clear mode, reducing the FPS from 20 down to 6fps or lower stops the audio from stuttering.
Disabling the hardware decoder setting causes stuttering to occur again, even at these low FPS settings, on both Clear and Fluent modes.

In addition to Joseph's idea, have you tried lowering the frame rate down to the min? Don't worry about bitrate or resolution, in my case with the android app on android 8.0, it was the frame rate that was causing the audio to cut in and out, anything higher than four frames per second caused the issue. It will be interesting to see if this fixes it as then it might mean there is a wider problem.

Hi @ReolinkShayla,

Re the above post, I'd like to ask for the settings to be changed for the editing of new posts etc as 10 seconds is an unworkable time frame between creating a post and realising you need to edit it. I am also struggling how you can collect reputation points so that I can get off the mark to allow easier posting end editing. Please can you help and advise.

Thanks

Hi @reolinkshayla,

Please can you tell me if you fixed the stuttering issues for Android 8.0 users using the app in this new version. This is not yet available in my region yet hence my question. I raised this issue before Christmas with your support team, provided numerous video clips and conducted numerous tests to help them diagnose the issue. The fault was found which was as soon as you increased the frame rate above 4 (yes 4!) on fluent / low quality, the audio would stutter making it impossible to hear what the person is saying at the door. The talk back function was not impacted. This is the same for the Clear / High stream channel aswell. Changing the resolution or bit rate has no effect. It's specifically the frame rate which is the problem. This points to a codec / software issue and I have been asking your technical support team for 5 months now to fix this issue.

This issue has stopped me in my tracks in purchasing a suite of reolink cameras for which I cannot progress until I know that this issue has been resolved. Please can you reply to me with what I hope is some positive news that mentions that this fix has been rolled out.

I have been waiting very patiently for a resolution on this issue and so I would be grateful for your prompt response on this.

Thanks

Hi @Jim_431415522513068

I am not a user of this camera but I have some technical understanding... My first suggestion would be to try a factory reset as per the pic. if this is different to your model, there maybe a reset button on the camera itself (which you'll obviously have to get off the wall to do no doubt). The next thing would be to check if the camera is using power by measuring the current to the camera. You'll need help from someone who has a multimeter to do this. If there is current (eg a few milliamps) then the camera is still alive and that might help the Reolink support team to diagnose it a little more.

Hope that helps a little

Great to hear you've acquired a CX810 - did you buy it or did you manage to get onto pilot group testing it? When you get this setup, please could you reply back with some reviews as finding any on the cx810 is currently hard to find. I am particularly interested in the capability of capturing clear (non blurred) images with people moving about (not standing still) when it's dark Hope this is possible soon. Thanks.

PS, @joseph_1979 editing a post is only allowed within 10 seconds?!! Please can you increase this as this amount of time is way too short!! Also posting a second reply (because I can't edit a post after 10 seconds means I have to wait either 600 or 1800 seconds!). Apparently I'm a 'New' user. How / when do I no longer become a new user as I've posted a number of replies already and replied to people?! It looks like I need to earn 5 reputations points. How do I earn that?

Hi @user_824156525916320_824156525916320 and all,

I'd like to see some reviews of the CX810, especially motion type reviews compared to the CX410. Can someone post some links? Thanks
.
PS. I suspect the only reviews at present will be reviews from people who were selected to test it out back last year - but that's fine. My main worry is that with a change to the resolution but no change to the sensor size, will not bring in any improvement to the quality of moving objects at night and in fact might be worse (if the fame rate is slower). Lots of questions but hopefully the reviews will help.
