Hi,
I can't connect the recorders for distributed recording:
https://drive.google.com/file/d/0B-R9TB2NjePxcDRSVm5NWU1pT2s/view?usp=sharing

The connection to the other computer is there but I still get the error message and can't proceed.

My network knowledge is somewhat limited, so is there a trick? Or do I have to setup a network with special settings?

I'm kind of stuck with my entire work here.

--Edit--
Here is the trace file.

Hello Alex,

According to trace (thanks for it!), the following TCP error takes place:


The most common reason for this error is firewall settings. Please, check that iPiRecorder.exe is allowed to send and receive TCP/IP packages on any TCP/IP port. This setting should be applied to all computers involved in Distributed Recording. Or temporary turn off firewall.

If it doesn't help, then it can be routing issue in your local area network. In this case the simplest workaround is to use Wi-Fi network, provided by your smartphone -- just turn on Wi-Fi access point on your iOS/Android/Windows smartphone, connect both computers to this Wi-Fi network, try Distributed Recording again.

How to turn on Wi-Fi access point:

• iOS (iPhone): https://support.apple.com/en-us/HT204023
• Windows Phone: https://www.windowsphone.com/en-us/how- ... connection

Hope, this will help!

Best regards,

Thanks for your reply.
Unfortunately my PCs are desktop computer with no WiFi hardware.
For the heavy work-load WiFi might also be impracticable.
(8 PS eyes, 3 PS moves, audio)

I disconnected my internet router and used a separate LAN switch. Still no success. The Network is there, I can transfer files, pinging the PC on each other etc.
I did netsh int ip reset,netsh winsock reset. Re-Installing the Network-driver and reseting their settings.
Everything works except for the ipi Recorder connection.

Turning on all kinds of win7 networking services and deactivating the firewall on both computers didn't help.

Well, I gonna google "TCP/IP packages" now to see if there could be some sort of permission or setup where I can control that.
Most TCP tutorials are about the Internet-connection thou (which is almost ironic).

Has it ever been tested over LAN or only on WiFi? If you have tested it on cable, what where your settings?
Are there dependencies like C++ packages, .Net updates. Will setting-up a manual IP-adress help?

I'm trying to production-ready for future contract work. Only if the distributed recording works I might be able to use your proposed 16 camera setup.

Hello!



You can use USB Wireless Adapters. They are rather cheap.




iPi Recorder doesn't transfer live data from all devices during recording. It performs file transfer right after recording is done. Also you can transfer separate iPiVideo files from slaves by yourself using USB 3.0 external disk for example.




There's no need in it. iPi Recorder uses regular TCP/IP (it uses TCP ports 31415 and 31416 if they are available. Otherwise, the program automatically switches to a random port number instead).




Sure. It was tested over LAN.




The configuration was simple: all computers were connected to one and the same router using ethernet cables.

Ok. So, as I suspected: I ordered WiFi Sticks and then:
created a Hotspot with my home WiFi router, didn't work.
Created an Hotspot with a Windows Phone, didn't work.
Created an Hotspot with a Android Phone, didn't work.

I also disconnected every other network as an additional test, so that there will be no interference, didn't help.

As usual everything works, except for the iPi Recorder.

I uninstalled the 2.x Recorder software, as it may have caused problems, no change.

At the moment I'm not convinced that this is working outside your in-house setup.

I had a web-developer check my network setups and he couldn't find any dysfunction in my setup.

Is there anything that can be done? Or was there only the "try WiFi" option?

Here are trace files:

It means that root of the issue is on your OS/software configuration rather then network itself. There's something (anti-virus, firewall, proxy?) that doesn't allow incoming TCP/IP connects on your computers.



Distributed Recording is used by at least hundreds of our users.



You can ask him to start any HTTP server on a random TCP/IP port on one of your computers. And then try to connect to it from another.



Find out which software cuts TCP/IP traffic on your computers.

It works!!!!

Ok, I had the Comodo firewall installed on both computers.
Comodo wasn't running on the slave and I deactivated it on the master, therefore I thought that would not be a problem.

No I just completely removed Comodo from both systems and now it works!

That means: Can you recommend a firewall? Because Comodo was the last time on my systems!!
(I didn't work with all permissions aaaand even deactivation!!11!!Why COMODO? WHY?!?)

Thank you, Andrew, for your support! :)

Supplemental:
After re-installing Comodo, I realized that something was wrong with its update system.
Because now it works even with Comodo.
In the end uninstalling and re-installing helped. I just had to reestablish the custom rule-set on both computers.
