Remote Connectivity Troubleshooting
Error Possible Causes
• Cannot connect to • Ports not forwarded
the NVR over the
Internet
• DDNS Setup not completed
• Ports are blocked by Internet
Service Provider (ISP)
• Multiple routers installed in
local network
• Could connect to • NVR internal IP address has
system previously, changed
but no longer can
• Cannot connect to • IP address used from outside
the NVR using a local network
smartphone or tablet
• Router is blocking DDNS
connection from internal network
Solutions
• Port forward the HTTP port (default: 80) and Client
port (default: 35000)
• Register for a DDNS account. For details, see
"Appendix D: Setting Up DDNS Service" on page 98
• Some ISP's block port 80. Reassign the HTTP port
to anything above 1026. Re-complete port
forwarding using the newly assigned port
• If you have multiple routers, additional setup may
be required. For details, see "Configuring Multiple
Routers" on page 95
• This can occur if your router resets due to power
failure. Set up a fixed IP address for your NVR. For
details, see "Configuring DHCP or Fixed IP Address"
on page 25
• Use the DDNS address to connect to the NVR
using a mobile application (e.g.
tomsmith.myddns-flir.com)
• Turn off WiFi connection and attempt to connect
using 3G or mobile network
