RLC cameras stream lagging on Client

[nickburt218]

I have a mixture of RLC 822A, 833A and 1210A PoE cameras all connected via a GbE Unifi network, each camera has a fixed IP address. Cameras are running 100Mbps (FE) - auto set by the switch port when the cameras are connected. PoE power is between 3 and 4.5W depending on camera, well within the capability of the switches the cameras are connected to.

All cameras are monitored via two Windows 11 pcs (both up to date with Windows updates etc.).

One pc is used to record all cameras 24/7 to a large NAS, the other is used simply as a means to display the camera feeds on a monitor.

Therefore both pcs are running 24/7, but both are set to auto reboot once a week, in doing this, Reolink is also set to auto restart on pc boot up.

All cameras and the client are running the latest firmware versions:
822A - v3.1.0.1643_22122401
833A - v3.1.0.1648_22122727
1210A - v3.0.0.177_21012104
Client - V8.14.2 - with auto update enabled.

All cameras are set to auto re-boot at 06:00 every day.

When displaying on a multi display screen, all are set to balanced stream, or when just one is being shown, they're set to clear stream.

After a number of hours running, all cameras end up a few seconds behind actual pc time. This gets worse, the longer they run for. This is irrespective of stream settings - even at the lowest stream settings, the problem continues to exist.

As a work around (suggested on cctv and Unifi forums), I reboot Reolionk once a day, which immediately resolves the problem and gets the camera times correct.  

But after only a few hours they end up 5 or 6 seconds behind and occasionally with a jerky/jumping display. For example, one might be 5 seconds behind, but will freeze for a few seconds then jump a few seconds to end up 5 or 6 seconds behind again.

The recorded downloads to the NAS are not affected, it is only the live feeds that are affected.

App on Iphone is fine, since we only have a quick look on a phone from time to time and don't leave it streaming for any length of time.

Speed tests on the Unifi network show it's capable of speeds of 400 - 500 Mbs. I have 500Mbs fibre internet for which the Unifi network hardware is more than adequate. All ethernet cabling is CAT6.

Cameras are showing speeds of 16 - 32 bps download and 168 to 200 bps upload, with round trip pings of max 3ms.

I've heard that Reolink can issue "bespoke" firmware upgrades for certain cameras, but surely, that gets defeated when the next version is issued and installed?

Has anyone found a proper solution to this?

[nickburt218]

For further testing, I've disabled the auto reboot and find that the lag remains the same. It doesn't appear to get much worse with time.

[joseph_1979]

@nickburt_442836936192165 Can you do a test on a single camera? If it happens again then use VLC and enable RTSP. See if the time remains the same. If yes then there is an issue in the client.

[nickburt218]

@joseph_1979 Sorry, only just seen your reply. I've now disabled 2 out of the 3 cameras and will see what happens over the next 2 or 3 hours.
Thank you.

[nickburt218]

Should also add - Hardware Decoding was switched off Saturday at Reolinks Support Team's suggestion, which appeared to make no difference.

[joseph_1979]

@nickburt218 That's to avoid hardware video acceleration but yes it won't have any impact on your issue. From the taskman what's the CPU usage when you run Reolink client? And the other resources?

Any update with one cam?

Another scenario to test is to use the web browser. Log to each camera through the Webui and leave them for some hours and check the time.

[nickburt218]

@joseph_1979
So far, in the last 6 hrs or so, there has been no signs of lag on the one camera running (the 833A).

Taskman shows Reolink using around 9% with just one camera (833A) running - which seems high. Nothing else running except some background processes adding up to a total of around 20% (i.e 11% background - of which about 6% is remote desktop)
I enabled another camera (822A) and the Reolink CPU usage went up to 10%, and then with the 1210A (so all 3 on), Reolionk CPU usage jumped to 38%!!
But, then disabled the 1210A, shut down Reolink client and restarted it with only the 833A and 822A running and now Reolink CPU usage is around 6% with 2 cameras running - strange.
I then disabled the 822A, shut down and restarted Reolink client and now have Reolink at around 4%.
I then tried with all 3 enabled, restart Reolink, Reolink CPU usage = around 8%
(Note - it's dark here at the moment, although all cameras have street lighting and garden flood light to assist at the moment).

PC is an HP EliteDesk 800G2 (i5-6500T @ 2.5Ghz, 8GB RAM, Win 11Pro N (22H2) OS build 22621.2861 all up to date.

Webui to try tomorrow.

[nickburt218]

The HP's only function in life is for monitoring the cameras on a TV screen via HDMI.

[nickburt218]

@joseph_1979
Have been running all 3 cameras using the Webui for the last 4 or 5 hours, one camera is now 1 second behind pc time, another is 2 and another 3.
It would be nice to see all 3 cameras showing the same time, given that they are all set to synchronise their clocks every 60 mins.
I am now going to try a firmware upgrade for the 822A provided by the Support Team via email and see if that makes a difference whne all 3 cameras are running as we've already proven that which just 1, the lag doesn't occur.

[joseph_1979]

@nickburt218 On each camera go to date & time under System and synchronise to your PC. I guess you don't block port 123 (NTP) on your BB router.

[nickburt218]

@joseph_1979
All cameras are set to auto sync every 60 mins

Firmware upgrade for the 822A has now been running for around 6 - 7 hrs. The 822A held the correct time for about 4 or 5 hours, but is now (7 hrs) 10 seconds behind the pc. The other two initially slipped in the first couple hrs to 5 seconds behind and now still 5 secs behind.

This more than just a little bit frustrating now ...............

Currently trying VLC on one camera - see what happens overnight.

[nickburt218]

VLC crashed at some point during the night

[joseph_1979]

@nickburt218 Try again on the 12M cam,

[nickburt218]

@joseph_1979
Have had the 822A running in VLC (as well as Reolink Client) for the last 7 hrs - Client 6 seconds lag, VLC 7 seconds lag.
Will try now with the 1210A only on VLC and shut down Reolink Client.

[joseph_1979]

@nickburt218 We need to do one more test, if you wish. Go to my reply in https://community.reolink.com/topic/6925/pc-client-v8-14-0/6?post_id=26768&_=1704918333976 and download v8.8,5. Install it and repeat the test. This is a 32 bit client. Do not run any other client.

[nickburt218]

@joseph_1979
OK, thanks, will do - I'll try it in the morning.

[nickburt218]

@joseph_1979
Set up and running, let's see how it goes. Nothing else running on that pc. Other version of the Client has been uninstalled.

[nickburt218]

@nickburt218 We need to do one more test, if you wish. Go to my reply in https://community.reolink.com/topic/6925/pc-client-v8-14-0/6?post_id=26768&_=1704918333976 and download v8.8,5. Install it and repeat the test. This is a 32 bit client. Do not run any other client.

Been running v8.8.5 on just one pc for the last 4 hours and clocks seem to be stable with little or no lag to be concerned with (1 sec) for each of the 3 cameras. Will continue to monitor this.

Going forward. My set up is:

1. A workstation running a Relink Client, recording 24/7 (not in use at the moment) - this is hidden away in a very inaccessible location. To access it, I use remote desktop. But obviously Reolink Client need to be running on it. This records to an internal hard drive, which is periodically copied to a v large NAS for future (and remote) reference should we need to view historical cctv footage. This workstation is also used to do other background and scheduled tasks.
2. A separate pc dedicated (the HP described above) used only for monitoring the cctv stream, with no recording to it set up. This is connected via HDMI to a tv, so live cctv can be viewed at any time.
3. The cameras all have sd cards in them and are set to record (overwriting) on motion detection only.

Would running the Client on two pcs in this way be detrimental?

[joseph_1979]

@nickburt218 Good. Thanks. I haven't seen other members with similar complaints on the latest version.

[joseph_1979]

@nickburt218 Give another 2 to 3 hours and see if there will be any time lagging. Then do your scenario.

[nickburt218]

@nickburt218 Good. Thanks. I haven't seen other members with similar complaints on the latest version.

That's interesting, as in hind sight, I think this only started with a later version.

[nickburt218]

@joseph_1979
Will do, thanks.

ps, at the moment, once I've made a post, I have to wait 600secs before being able to post again ....... hence the delay with this post ..... something about reputation !!!!

[joseph_1979]

@nickburt218 It seems that an Indian using Airtel ISP was sending non sense messages. He has been blocked.

[nickburt218]

@nickburt218 Give another 2 to 3 hours and see if there will be any time lagging. Then do your scenario.

Ok, so, some 9 hrs later and still only 1 sec lag between pc clock and Client clock - which I can live with.
Now running as per the set up I described earlier. Both pcs running v8.8.5.
Time will tell.

[nickburt218]

@nickburt218 It seems that an Indian using Airtel ISP was sending non sense messages. He has been blocked.

But I still get the "once every 600 secs" notice:

[joseph_1979]

@nickburt218 it seems that the time lagging is somehow caused by the 64bit client. What's the CPU usage when using 8.8.5?

[nickburt218]

@nickburt218 it seems that the time lagging is somehow caused by the 64bit client. What's the CPU usage when using 8.8.5?

5 hours later and there's a 6 second lag on the HP that's only streaming. The other workstation that's recording is fine - 1 second lag.
CPU usage on the HP is fluctuating between 27 and 28%
On the Workstation (while recording continuously) cpu usage is a similar 27 - 28%.

PC doing the streaming:
HP EliteDesk 800G2 (i5-6500T @ 2.5Ghz, 8GB RAM, Win 11Pro N (22H2) OS build 22621.2861
Workstation doing the recording:
Dell Precision Tower 3620 Intel(R) Core (TM) i7-6700 CPU @ 3.4Ghz, 40GB RAM, Win 11 Pro (22H2) OS build 22621.3007

But, I've just connected with Remote Desktop to the HP from another laptop and the clocks are spot on!
Then dropped the Remote desktop connection and the HP was then showing the correct times!!!!! Weird. Wonder if the HP HDMI video output is causing the delay.

[nickburt218]

@joseph_1979
This morning, the HP was fine. TV was switched off last night and back on this morning.
The Dell workstation had frozen the display for all 3 cameras at around 01:30 (monitor had been left switched off) and recording stopped at 06:00 (is set to record in 10 min chunks.. Had to reboot Reolink Client to get it all working again. This is something that wouldn't normally get noticed as the workstation is usually just left to get on with what it does, unless something is needed.

[joseph_1979]

@nickburt218 Are the PCs connected to the same network as the cameras? If this was lagging from the camera then it would have certainly remained unchanged. So it seems some video delay on your system. When you see the delay, can you use your Android/IoS application to see the time on the camera?

[nickburt218]

@joseph_1979 Yes, pcs and cameras are on the same network. 2 of them via 2 layer 2 switches, one via just one.
So far, the lag hasn't re-occurred. I'll keep an eye on it and if it does, check via the IOS app on my 'phone and iPad.

[joseph_1979]

@nickburt218 Good. And you are running v8.8.5 right?

[nickburt218]

@nickburt218 Good. And you are running v8.8.5 right?
Yes.
But, both left running for the last 24 hrs and both ahve a 5 - 6 second lag, and sometimes freeze for a couple of seconds, then jump to catch up to 4 or 5 seconds lag.
Cameras are syncing every 60 secs.
PCs sync once a day.
However, Client time is same as pc time, but displayed time is the one that's lagging:

[joseph_1979]

@nickburt218 Did you check the time through the Android application when it shows a delay of 6s on the PC (you may use the Webui from same PC)? The display time is the one produced by camera. Is NTP enabled on cameras? Is port 123 allowed through your BB router?

[nickburt218]

@nickburt218 Did you check the time through the Android application when it shows a delay of 6s on the PC (you may use the Webui from same PC)? The display time is the one produced by camera. Is NTP enabled on cameras? Is port 123 allowed through your BB router?

On the IOS app on my 'phone, the displayed time is correct. Same for Webui on the same pc
NPT is working though port 123 - all attempts to synchronise the time are successful.

[nickburt218]

If I were to restart the Reolink Client, the displayed preview (and therefore time) would become correct again.

The cameras "know" what the correct time is (as seen in my screen shot a couple hours ago), but after a while, the displayed preview (and therefore time), is lagging. i.e. if I exit a door, the display shows me exiting the door several seconds later, but at the correct time.

Turning the monitor/tv on or off has no effect.

PS, I still can't post more frequently than every 600 seconds for some reason???

[nickburt218]

This has got to be something to do with the way the image on the camera is being transmitted from the camera, through the Client to the PC.

[nickburt218]

@joseph_1979
Strangely, this morning, the monitor on the HP is still 5 to 6 seconds lagging, but the monitor on the Dell workstaion is back to 1 sec behind.
As above: This has got to be something to do with the way the image on the camera is being transmitted from the camera, through the Client to the PC.

[joseph_1979]

@nickburt218 So this means that the time on the camera is correct and subsequently the issue seems to be in the way the image is displayed by the client on the PC. Can we change the priority of the Reolink client? Start task manager and go to tab Details. Find the Reolink processes and set it to a higher priority. Realtime may kill your processor....I guess. Do it on the PC where there is the highest lag.

[nickburt218]

@joseph_1979
Priority of all Reolink process changed from normal to high on the HP pc.
Haven't re-started the Client yet, so still 5 to 6 secs behind.
In the last 2 or 3 hours, the Dell workstation has gone back to being 5 to 6 seconds behind again!
So I've done the same on that one, but have re-started Reolink so we can see if there's any differences.

[nickburt218]

@joseph_1979
HP pc ended up having a forced re-start of the Reolink Client just now .............. it crashed!

[nickburt218]

@joseph_1979
6 hours later @00:14 - HP is 1 second behind and Dell is spot on.

[joseph_1979]

@nickburt218 let's wait for some more hours. I think we have exhausted all the tests.

[nickburt218]

@joseph_1979
09:00 next morning and they're both still within a second.

[nickburt218]

@joseph_1979
12:30 and they are both lagging by 6 seconds.
I'm away now until late tomorrow night, so I'll leave them running and see what's happened when I get back.

[joseph_1979]

@nickburt218 I see that the max lagging time is always 6s. I have left my notebook running Win client on 3 RLC cams. They differ 2 seconds from my PC time. I didn't synchronize them to the PC. Will see if the 2s will be maintained.

[nickburt218]

@joseph_1979
20:00 hrs. Just checked from afar using the iOS app on my phone, and that's lagging by 2 to 4 seconds, depending on which camera I look at.
But that could just be slow internet.

[joseph_1979]

@nickburt218 I did leave the notebook for 8 hours and the lagging was 2 seconds. It didn't change at all. All my cams are synchronized to NTP every 1440min. If it remains constant then I do not consider this as an issue. I do not think the issue is within the camera as otherwise I would have seen lots of complaints at the community and reddit.

[nickburt218]

@joseph_1979
Just got back (21:30).
Reolink Client on the HP had shut down at some point. Don't think this was any sort of PC re-boot as Reolink is set to run on PC start up. So, possible just a Reolink crash of some sort.
On the Dell workstation - all still running and still with 5 -6 secs lag. So, as you say, lag is consistent, although it takes a while to manifest.
No idea what's causing the lag, but it is still an issue for me. Makes using the cameras for live monitoring useless. The jump to catch up a couple of seconds is also not good. One, or more of he cameras will be lagging, say 6seconds, then pause for a second or two, then jump forward to be 6 seconds behind again.
Someone can be at the front door, ring the bell and be walking away again, before we can see who it is.

[nickburt218]

@joseph_1979
08:30 this morning
HP is showing correct time on 2 cameras, but 7 second lag on one (the 1210A)
Dell workstation is 1 sec lag on all 3.

[joseph_1979]

@nickburt218 If there is an issue on the camera side, then the lag time should show on both HP and Dell PCs. How is the Dell connected to the network? Do you have any switches and routers? Can you draw a sketch diagram of your setup? I also assume that the cat cables have been tested and connection between PCs and LAN is secured.

In my opinion the issue is within the client.

[nickburt218]

@joseph_1979
Further info @ 17:30
On HP, 2 cameras (1210A and 833A are 6 secs lagging, 822A is 1 sec lagging
On Dell, more or less the same.
No restarts or re-boots occurred since this morning. No updates done (either Windows, or Reolink Client or cameras.)
If the issue is with the Client, what's the solution?

Network sketch.

[nickburt218]

@joseph_1979
08:30 this morning
Both monitors were turned off last night, but both HP and Dell left with Reolink Client running.
When switched back on this morning:
HP pc - 822A display was 5 secs lagging, but 822A and 1210A both spot on.
Dell workstation - all 1 sec lag

[joseph_1979]

@nickburt218 Sorry was busy with a mobile operator implementing Volte.

The 1-2 seconds lag is expected which is due to transmission and processing. The network is good and the switches are functioning at L2. I have one last request, namely, to disable the hardware acceleration first (from main menu of the client) on the HP and to connect the HP to the same switch as the DELL. Just for testing.

At the same time I kindly ask you to open a ticket with Reolink support (support @ reolink . com - Remove spaces as the site won't allow us to add links).

[nickburt218]

@joseph_1979
18:30 Complete restart.
Both HP pc and Dell workstation restarted with both connected to the same switch (the US-48).
Reolink Client re-started on both (auto start on pc boot up).
Reolink Client on both machines has the "Hardware decoding first" switched off (there isn't an option for hardware acceleration in V8.8.5 - or if there is, I don't see it).
All clocks checked and synchronised.
HP pc - camera clocks = 1 sec lag on camera compared to pc clock
Dell Workstation = 1sec lag on camera compared to pc clock.
I can live with 1 sec lag.
Let's see what happens.

This has been submitted to Reolink support already. Ticket #1492257 submitted on 05/01/24 (couple of days before I started this topic on here).
Within my emails to support, links to this topic have been included, so they are, or should be, completely aware of everything we've been trying. However, the extent of actual support has been, quite frankly, absolutely rubbish.

I don't mind getting involved in testing and experimentation, (for example, for this latest test, I've had to make up a temporary Cat6a patch lead to get the HP pc connected to the same switch as the Dell - how many users would be able (or willing to mess about) to do this?), but this has been going on for long enough now.

At one or two points, I was beginning to doubt myself, my network and hardware in terms of pc specs, network design etc.. etc.., but I am absolutely convinced that's not the problem, it's something in the Reolink Client. My Unifi network is rock solid and never misses a beat. Combined with full fibre to the house and failover to Starlink in the event of fibre failure, I have a robust solution.
All I want here is a cctv system that works and does what it should be doing, which, to be fair, in the main it does. It records 24/7 with no problem, it detects and records specific motion activities with no problem. It's just this live view lagging issue that lets it unacceptably down.

I am considering increasing the number of cameras covering my property, but the jury is out at the moment as to weather that's Reolink Cameras or a more significant investment in Unfi Protect ........

[nickburt218]

@joseph_1979
23:30 - all still good at 1 sec lag.

[nickburt218]

@joseph_1979
08:10 all still good at 1 sec lag

[nickburt218]

@joseph_1979
14:30 and all are back to a 5 sec lag

[nickburt218]

@joseph_1979
17:30 - all gone back to 5 to 6 secs lag - all of them

[joseph_1979]

@nickburt218 If course not everyone ulis technically good and able to do such tests. Network is not an issue at all and neither the cameras. I think that the issue is with the client on certain environment. If I am the developer I would add debug points and logs. This is what I did when I used to develop applications in Visual Studio.

Lagging was never more than 6 sec and sometimes it is normalised. You stated that port 123 is allowed from each camera for NTP to synch and so camera should synch the timestamp on the hour.

Can you send an email to Reolknk Support and get you in contact with the senior support team? Your case needs further investigation from the senior support.

[joseph_1979]

@nickburt218 Let them till tomorrow and see if the lag time increases more than 6 sec. And if you check through Android appl it is good.

At Reddit there are a lot of Reolink users who have been through a lot of issues and may have had a similar issue. Can you please join us at Reddit too and copy and paste your initial input? We are trying to help you.

[nickburt218]

@joseph_1979
Thank you for the reply.
Port 123 is allowed for NPT:


I have emailed Reolink Support to escalate to senior support.

I'll have a look at Reddit, but I really don't want to start from scratch and end up having the same suggestions made that we have already tried, that'll just end up being a waste of everyone's time. But I will take a look.

09:20 this morning.
HP pc 822A is 3 secs behind, the other 2 cameras 1 sec lag.
Dell Workstation all 2 secs lag.

[joseph_1979]

@nickburt218 I think it is very difficult to have them synchronised to the PC clock. You need to allow between 1 and 2 seconds.

Have you thought of integrating the cameras to a HA?

[nickburt218]

@joseph_1979
17:00 this afternoon
HP pc 822A is 10 secs behind, the other 2 cameras 6 sec lag.
Dell Workstation all 1 to 2 secs lag.

[nickburt218]

@joseph_1979
22:30 - notice the Client on the HP had crashed. Rebooted.
Dell 1, 3 and 6 secs lagging.
Coming to the conclusion Reolink Client needs to be binned and find another solution.

[nickburt218]

@joseph_1979
09:30
HP is fairly good - around 1 sec lag on all 3 cameras.
Dell Workstation is 5 - 6 secs on all 3.
After a bit of discussion on Reddit, it has been suggested on that running the Client 24/7 is not the intended way of operation, nor recommended, and that I should be using an NVR to do my recording.
So far, no real solution to the lagging cameras issue.
Still no reply from Reolink senior support, but it is the weekend, so I'll hang on a couple days. But given I raised this two weeks ago .............

[joseph_1979]

@nickburt218 In my opinion, Reolink Client is not meant for continously monitoring but rather a tool to view for short periods and performing maintenance on the cams. You need to have a look at having an NVR or a HA. In case of NVR there is no other option other than having the Reolink NVR. In case of HA there are a lot ...BI, Frigate, etc. In my setup I save on SDs and ftp the clips to an Linux ftp server.

I think we have performed all possible tests and in the absence of the source code of the client we cannot delve further. But still continue to take it up with senior Reolink Support.

[nickburt218]

@nickburt218 In my opinion, Reolink Client is not meant for continously monitoring but rather a tool to view for short periods and performing maintenance on the cams. [snip]

This is a shame, and not how I understood the comment on Reolink's website:

24/7 monitoring, to me, means being able to view 24/7

[joseph_1979]

@nickburt218 You are right. This is my personal opinion and is shared by a number of honest customers. I still urge you to continue liaising with the senior support.

I told them that they need to improve the stability of the clients together with more resources in sw development and testing. I have been leading teams of engineers and know what it really entails.

[nickburt218]

@joseph_1979
21/01/24 @ 22:20
Dell - all cams around 6 - 7 secs lag and trying to jump forward a couple secs now and again.
HP - Reolink Client crashed twice in the last couple of hours. So, at the moment, times are correct to within a second.

[joseph_1979]

@nickburt218 HP is correct because you have restarted the sessions. Leave Dell running and we will see if the lagging continues to increase further.

Can you try BI for a few days? Maybe there is a trial period. I haven't used it.

[nickburt218]

Had this from Senior Support this morning:
"Regarding the delay issue on Reolink Client, sorry to tell you that we have no futher advice for the moment. But we will keep optimzing the Reolink Client to reduce the delay in the future.
 
Thanks for your understanding."
Clearly no solution.

I'll have a look at BI, but really running out of enthusiasm (and time) for this now. Maybe I should invoice Reolink for my time spent on this for them !!!!!!

@nickburt218 I think so. I tried my best to assist you but it is the supplier who knows his products. I did a lot of applications to my customers and always provided a solution whenever there were issues.

[nickburt218]

@joseph_1979 And I thank you for your help and suggestions.

@nickburt218 They have released a new Windows client 10.15.6 at https://reolink.com/ca/software-and-manual/. Can you check it out? It seems that this client is using less CPU resources.

@joseph_1979
23/01/24 @ 21:10 - 10.15.6 installed on HP pc only.
Note - full uninstall of previous version needed to get it working.
Auto Client update disabled
Hardware Decoding off
No recording via Client
Let's see how this goes.

10.15.6 still running on the HP pc. Seems to be a lot better, max 2 to 3 secs lag though still there after a number of hours running. Almost acceptable, but still annoying.

Another issue has developed in the last couple days. The Reolink Client on the Dell workstation shuts down at the same time every day (twice now) at sometime just after 11:30.
No idea why, and haven't had the time to investigate. The only thing that has changed is that while we were testing over the last couple weeks, I've had a monitor, keyboard and mouse connected to it rather than using RD and they were unplugged and removed in the evening of 23rd when doing the Client update on the HP.
This one is concerning though, as it's the Client on the Workstation that does the 24/7 recording.
Will se what happens tomorrow and if it does it again, daft as it seems, I'll put the monitor, keyboard and mouse back on it.

HP pc still at 2 - 3 secs lag.

[joseph_1979]

@nickburt218 Ensure that you update both PCs. Can you check from Windows event viewer and check appl and system logs at that time and see if you are able to discover anything?

Personally, 2 to 3 s are acceptable.

No more support from Reddit .... I thought they will bombard you..

[nickburt218]

@joseph_1979
Just about to update the Dell with 10.15.6
No idea why the Client stopped two days running at 11:30 ish - hasn't done it today! Need to find the time to review event viewer and system logs - struggle due to work load !!!!
Guess 2 to 3 secs isn't going to be improved on.
Disappointed with the response on reddit.

@nickburt218 Uninstall and install. Might have to add cameras using the UID.

[Jing_734911040270566]

@nickburt218 I have the same issue. I have found that if you open an individual stream then go back to the multi view the cameras are in sync again. You can also close the client and Re open but it is faster to just go switch back and forth.

[joseph_1979]

@jing_734911040270566 Thanks. This will cause closing and opening the session. But lagging will eventually re-appear.

[nickburt218]

@joseph_1979
Just installed 8.15.6 on the Dell.

[joshblaylock_130906780041457]

@nickburt218 I suspect an issue with the hardware you are using not being able to decode H.265/HEVC codec adequately (I think I am running into the same issue).

The fact that it is working with little lag on the mobile app with a layer of wifi added would seem to indicate that it is not a problem with the network. I've noticed that if I try to play H.265 video in high res from my mobile device on the same computer, I also have stuttering, lag and occasional freezes.

I installed the Reolink Client on a Windows 11 laptop that was purchased recently and do not have the issue there.

I don't know if there is a better codec that could be installed to resolve the issue or if the hardware/cpu just isn't designed to handle that decoding algorithm....

[nickburt218]

I've also had the Reolink Support Team email me back now with:
"Sorry for the issue they caused, would you accept we provide 20 GBP refund as compensation for you to keep using them?"

So, I've been offered £20 compensation for over £200 worth of cameras, that don't do what they're supposed to do !!!!!

[nickburt218]

@nickburt218 They've replaced this offer with a 10% discount on future purchases - which I'm currently unlikely to do unless the lag issue is resolved satisfactorily.
In the future, I would be interested in adding cameras to the system, but at the moment .......... hmmm.

Last reply a couple days ago:

Sorry for this happened, we already forwarded your feedback to the relevant department, but currently, we have no better solution for this issue.
Or do you have any good idea or solution you want?

[bill doria]

I have the same issue.. My setup is (4) RLC-820A cameras, connected the Reolink NVR..
All have the most current firmware, and Reolink Client on Windows 10.
When there is a delay, I get the icons on the screen (let's say for vehicle motion), I can hear the vehicle drive by, and the video will show the vehicle drive by 5 seconds later.

[herringburdensome_603767752639193]

@bill-doria I've noticed the exact same problem. I have auto power on enabled on my computer, which launches the reolink client when the computer boots up, and if everything is unchanged, the live broadcasts begin to lag.

[160334357029011]

I have noticed the same exact problem. I have auto power on setup on my computer which will then startup reolink client when the computer has booted up and if everything is left untouched, the live streams are beginning to lag. In the afternoon, the lag can be anything from few seconds to a whole minute. I have witnessed a lag of well over 30seconds. I literally was able to see myself entering the property on the live screen when I just sat down infront of the workstation. All cameras are with latest firmware, I'm running client 8.8.5. because anything else after that has been garbage. Where are my compensations? I have 4 cameras and not the cheapest ones on the line.
