Having the worst problem with the webcams showing on my website

The cams used to stream and now I cannot get them to show up. There are blank boxes. I have tried everything and even my IT guy has been here twice. Anyone have any help for this? I emailed support and heard nothing back.

When did you email support?
Since it has been working what changed?
Send detailed description to support.

I emailed support on Monday. I don’t know that anyting changed, I am not that good with this type of issue. Do you have a support email? Or should I use the contact on the website?

Use the Contact on the website.

I just sent it in. thanks

New modem need new configuration of port forwarding of default port 8100 to NCS server computer.
