Is it possible for sensor default action out of box to be playing a IP address upon activate short wire or switch? It would be easy to access device in case that DNS query not resolve name gsc_macaddress.local or just troubleshooting IP connectivity.
We will note your feedback.
We have a tool that we used to find all Grandstream products that are in the same network, it’s called GS_Search tool. You can find it in our website: http://www.grandstream.com/support/tools
You can try to use this tool and see if this could make it easier for you to find the IP Address of the GSC3510 instead of using gsc_macaddress.local that we suggested.
