Picture Node: Network timeout

[GeorgWolter]

First of all I would like to say thank you and best from Germany👍

My cameras are abroad so I am using a VPN which works fine with http-access to cameras via Firefox and iVMS-4200. Current issue: The picture node's attempt to connect to a camera leads to a timeout.

topic: "" errorDescription: "network timeout at: http://192.xxx.xxx.xxx/ISAPI/Streaming/channels/101/picture" payload: true

[Supergiovane]

Hello, I think i should increase the timeout. I’ll do it sofort, so you can try.

[Supergiovane]

V 1.0.6 is out. The timeout is now 15 seconds. It should suffice. Let me know. Thanks.

[GeorgWolter]

Great, that's performance👏 Just waiting that Nod Red is offering the V 1.0.6 in menu "Palette".

[GeorgWolter]

V 1.0.6 installed but it's still saying timeout. Anything I should configure in the camera maybe? I guess the node will work even via VPN. Cameras I have: DS-2CD2T63G0-I8 AND DS-2CD2T85FWD-I8

[Supergiovane]

Hmmmm... 15 seconds should be enough. The heartbeat fails as well some seconds later. What appens if you copy the URL of the first debug message, pasting it into web browser?

[Supergiovane]

And... can you issue a node -v command in a node-red console and tell me if you’ve at least Node v10.0.0 installed?

[Supergiovane]

Other than that, have you enabled the Isapi/CGI option in the camera?

[GeorgWolter]

• What appens if you copy the URL of the first debug message, pasting it into web browser?: Works fine. I see the picture.
• Result from node -v command: v12.20.0

[Supergiovane]

There is only the CGI thing. Can you check it? And.. how many seconds passes between the calling of URL and the image shown?

[GeorgWolter]

• No success after activating CGI
• Time between calling URL and picture: < 1 second

[Supergiovane]

After installing the v1.0.6 have you restarted nodered? If yes, how about changing the authetication from “digest” to “basic” in the config node and restart node-red?

[GeorgWolter]

• Yes, I have restared Node Red as requested
• Node: Changed authentication from “digest” to “basic”: Still timeout

[Supergiovane]

Tried yet with my VPN and all is fine.

[GeorgWolter]

Strange 😊 I am running Node Red on a Raspberry Pi in my home network And I have another instance running on DS720+ VMM (see issue #2)

[Supergiovane]

Do you maybe have WIFI and Ethernet both active on your PI? You could disable the WIFI to see if it fixes the issue.

[GeorgWolter]

Pi: I am using a LAN / PoE-Hat. WiFi is not active.

[Supergiovane]

Ok, let me do some more checks tomorrow, once in office. I'll try to ditch into this issue. It's for sure related to some other timeout... I'll keep you posted.

[GeorgWolter]

👏 Thanks

[Supergiovane]

PS: in the meantime, revert to digest authentication ;-) Last but not least... have you tried calling the URL directly from a browser on Raspberry?

[GeorgWolter]

Raspberry / Browser: Not yet tested My 3rd test-environment: DS-720+ with Node Red running in Docker: Node Installation works fine but no connection to cams.

[Supergiovane]

Hi Georg. Is nodered on docker able to reach the internet or you vpn? You should be sure thath the Raspi and nodered on synologi are able to reach other end of your vpn.

[Supergiovane]

Hi Georg. Is nodered on docker able to reach the internet or you vpn? You should be sure that the Raspi and nodered on synologi are able to reach the other end of your vpn where your cams resides.

[GeorgWolter]

Will verify that until tomorrow and I think you are completely right. And in the next week I will get a camera to my place here. Then no need for VPN anymore😅

[Supergiovane]

Georg?

[GeorgWolter]

Hi, have thought through the infrastructure and realised that the problem lies here. Certainly not in your software. Working on establishing a VPN Site-to-Site connection from my Fritz!Box in Germany to my remote site abroad (UniFi USG).

[Supergiovane]

Good luck. I ended up using opnSense on both ends to do a reliable openvpn connection. I had the same as you, fritzbox and usg.

[GeorgWolter]

Yes, I am facing the same trouble. I am close to saying good bye to my FB6590 and buy a Dream Machine Pro for Bremen. How does your VPN infra (HW) look like?

[Supergiovane]

Hi Georg, I have a star configuration. Due to the fact that my internet connection at home doesn't have a fixed IP, i bought a cloud subscription from Hetzner.com (or .de, i cannot recall now) for ca. Euro 3,00/Month with fixed IP. I've installed an opnSense firewall on this machine. OpnSense has OpenVPN client/Server built in. This machine works as OpenVPN Server. Then for my home, i've installed a VM on my QNAP, with opnSense as firewall, having openVPN client connected to the Hetzner openVPN server's cloud machine. This give me a fixed IP for my home. My primary firewall is obviously the opnSense on the Hetzner cloud machine (because it "sees" my home's internal IP subnet, that is routable as well!). At home of the mather of my wife, i installed a super very good Telkonika router (it has two SIM slots and it can connect to a WAN as well , working as OpenVPN client: https://teltonika-networks.com/it/product/rutx11/). This Teltonika router is connected to a Fritzbox (working only as modem for a landline internet connection and a DECT server for phones in her house). This teltonika router connects with the Hetzner cloud machine as well, so from my home, i'm able to connect to the entire subnet of my wife's mother's home. My only Unifi gears are switches and Access Points. Unifi routers are way so limited for my needs.

[GeorgWolter]

Thanks for the detailed description👍

[GeorgWolter]

Hi Giovane, i see that the launch of REOLINK's new 4K RLC-810A and 510A is ongoing. Both got person and vehicle detection.

An interesting test on YT: https://www.youtube.com/watch?v=fxpxuv5Cmd0

Do you think you can develop nodes...?

[Supergiovane]

Hi Georg, nope sorry. I develop only for gears i own. I own only hikvision stuffs!

[GeorgWolter]

I See. Otherwise I would maybe send you a Reolink.

[GeorgWolter]

Giovane, buon Natale! Just thought I'll let you know that I will get a DS-2CD2645FWD-IZS very soon. So if you think that some testing would be from benefit for your projects then very welcome.

[Supergiovane]

Hi Georg Wow, good! I’m sure they work flawlessy with hikvision-ultimate!

[GeorgWolter]

I'm very sure of that too👍

[GeorgWolter]

DS-2CD2645FWD-IZS is working well. Should come up now in the compatibility list.

[Supergiovane]

Thank you. If you click “connect” in the config window, it will be automatically added here www.supergiovane.it:8080/?read=true&md=noCD&fw=no
