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:
- 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
