Ah, yes I missed that second link, thanks. So it doesn't actually fail. You can see the timestamp incrementing still.

That looks more like MTU issue or a TCP windowing error. Try looking at a pcap of that traffic. Is it full of errors and/or retransmissions?

@stephenw10

The cap is below See file attached, wyzeCAP.txt This is from when I loaded the cam in the App from my Mobile Phone. So the stream is coming through Port 10001 (UDP), I see a Secure HTTP from wyze to my phone prob to auth, and then starting to stream. The packet lengths vary. It seems that its a direct connection from the Cam to the App for this stream, its not uploading to the cloud (If Im reading this right).

Currently NO rules blocking TCP/UDP are in play.

This is all new to me so forgive me for any ignorance.

I tried finding my MTU.

└─$ ping -M do -s 1500 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 1500(1528) bytes of data.
ping: local error: message too long, mtu=1500

└─$ ping -M do -s 1472 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 1472(1500) bytes of data.
76 bytes from 8.8.8.8: icmp_seq=1 ttl=58 (truncated)

└─$ ping -s 1472 -M do 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 1472(1500) bytes of data.
76 bytes from 8.8.8.8: icmp_seq=1 ttl=58 (truncated)
76 bytes from 8.8.8.8: icmp_seq=2 ttl=58 (truncated)

$ ping -s 1473 -M do 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 1473(1501) bytes of data.
ping: local error: message too long, mtu=1500

So 1472 + 28 = 1500, so the MTU is 1500 or 1472?

Then MSS

MSS = 1500 - 20 - 20 - 8 = 1452 bytes.

Or

MSS = 1472 -20 -20 - 8 = 1424 bytes

Am I on the right path?

1500 is the default so that's expected. Where were you testing that from though?

I note the maximum packet size the camera is sending is 1117. Or at least that's the largest packet captured. Where was that pcap taken?

djskott

@stephenw10 I was pinging from my laptop connected to the VLAN the cams are on. The cap was taken from Pfsesnse's packet capture tool.

johnpoz

@djskott what specific version of camera is this? I half a mind to order one to play with..

djskott

@johnpoz I have a Mix of the V3 and Floodlights w/ V3 cams.

I would think the pan model would be exactly the same when it comes to networking.. Which is less than $2 more..

edit: Well my v3 "pan" will be here tmrw ;)

On which interface though?

If that was on WAN try looking on the VLAN. There might be more traffic there that isn't shown on the WAN. Which would be a big clue.

djskott

@stephenw10 That was from the VLAN

Here are Caps from when I initialize the Cam from My Phone (Not connected to LAN):

VLAN wyzeCAPVLAN200.txt
WAN wyzeCAPWAN.txt

johnpoz

@djskott txt caps are not very useful.. just upload the actual pcap file..

djskott

@johnpoz My apologies

Due to size using links

WAN: https://www.djskott.com/thingsthatgohmm/pcapwan.zip
VLAN: https://www.djskott.com/thingsthatgohmm/pcapvlan.zip

stephenw10

There are only 8 packets in the WAN pcap there to the cell IP. And they are all small.

You probably need to filter than pcap by the remote IP so it doesn't get swamped by other WAN traffic.

djskott

@stephenw10 When I filter the Phones IP, i see a string to the Modem and then nothing.

packetcapture-em0-20230829082635.pcap

stephenw10

That's on the WAN? Do you see more on the VLAN?

Also that's a different IP, did the phone just get a new IP?

djskott

@stephenw10 It's entirely possible that the device picked up a new IP from the Carrier. I am seeing a different IP in the VLAN than i do with the WAN now that you mentioned it.

Here is the VLAN as of 1056a https://www.djskott.com/thingsthatgohmm/pcapvlan200-1056.zip

stephenw10

What we're looking to do here though is make sure the UDP stream looks the same on both the VLAN and the WAN. Potentially some MTU difference could be dropping traffic there for example. I don't think that is happening but we need pcaps from both interfaces where the IPs used are the same ideally.

feed will spike up to 50-100ish KBps and then drop to zero and hang for 2-5 seconds then spike and hang,

How exactly are you seeing the speed, is it something on the app that reports this? I haven't watched your videos yet.. But just got it setup, pretty slick actually. It did a couple of firmware updates.. But I didn't have to forward any ports.. Turned my phone off of wifi, and its viewing just fine, and responsive to my panning, etc..

I just need to figure out where to view some sort of speed, etc.. I will watch your videos

edit: ok do you have subscription or something, I am not seeing any speed on my app on my iphone.

But in your video there is no movement, why would you think it should constantly be showing bandwidth, let me see I think there is a free 1 month trial of plus, etc.

edit2: ok started a free trial of plus, and still not seeing where it shows kbps.. Just shows HD.. The camera is very responsive, the feed is not behind, etc. I am not seeing any problems, and I didn't need to open any ports..

You sure your speed thing is just not the normal compression it does when there is no movement?

Is there some trick in enabling viewing the kbps? I have tried my ios, and my android tablet - I don't see anywhere to turn that on or off? But so far from the few minutes of playing with it.. Pretty impressive for the 30$ price range.. Now need to figure out exactly if I have anywhere to mount it ;)

edit3: Well shit... from this post it seems the kbps is missing on the pan v3..

https://forums.wyze.com/t/display-bitrate-on-all-new-cam-ui-live-streams/248979
All other Wyze cams display the bit rate data transfer speed on both the Live Stream and the SD Playback. This is a very useful tool in troubleshooting playback and streaming issues to identify network problems.

The V3 Pro and PanV3 cams should not be the only cams in the Wyze stables to omit this display function. [Edit: Even the OG has it] Bring back the functions that are useful!

edit4: Ok doing a bit of playing, so I pointed the camera to video playing on screen, and watching on my phone (via cell data only - no wifi) and was pretty good picture, decent amount of movement, I could prob watch movies that way ;) Was getting alerts of people detected ;)

Anyway was seeing this bandwidth being used

Then pointed it to something not moving, and bandwidth dropped.. And you can see here where dropped more is when changed mode to 360p..

So far I am not seeing anything wrong here.. Works as it should, and I had to do zero on pfsense for this to just work out of the box.. I wish I could see what the app is showing for kbps and I could compare that to actual data I am seeing for bandwidth.. With just looking at the wall was seeing about 900k when switched to 360p mode that dropped to like 300k.. Then moved it up to hd and the bandwidth went back up..

Ha

@johnpoz

Thanks for sharing this.

I have the cam plus lite sub.

Before pfsense even with zero movement (while streaming via cell service) the clock would tick up in seconds and the bw on KBps would jump all around. Never to zero, never hang on zero.

I'll try to do some more pcaps this weekend and take some ss of the meters.
