What ports need to be open for the cameras?

If you maintain a locked down network, you'll need to configure your firewall with the following rules for the cameras to function properly.

Outbound firewall rules:

• HTTPS/443
• UDP/53 – DNS
• NTP/123 – NTP Time Sync

Furthermore, if accessing cameras over a LAN, you need to ensure you have routes setup to the camera local subnets from the subnets where they need to be viewed on the LAN.

Intranet firewall rules/Routes:

TCP/8000 for LAN subnets 192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8

We also suggest whitelisting the following URL's if your firewall is really restrictive about the network traffic.

• *.rhombussystems.com
• *.lan.rhombussystems.com
• *.dash.rhombussystems.com

If you're using a firewall, you cannot man-in-the-middle (MITM) Rhombus network traffic as the cameras will detect this activity and stop the connection.
