9-7DDNS CongurationTrouble with Remote Viewing on Browser

Chapter 9: Troubleshooting

DDNS Conguration

DDNS allows you to tie your IP camera's IP address to a hostname with which you can access your it over

the Internet. If your IP camera obtains IP address via DHCP mode (automatic assignment of IP address), you

can enable the DDNS feature under the IP camera's network setting and register for a DDNS (Dynamic DNS)

service. The hostname can be obtained from Compro’s free iDDNS service or by applying from other DDNS

service providers such as DynDNS or no-ip. After you complete DDNS service application, you can then log in

to the IP camera's setup page, and look for [Network] > [DDNS] and provide all the required information and

save the settings.

Using Compro iDDNS Service

If you want to use Compro iDDNS service, you can run the Compro iWizard again and choose [Yes] in the step

for iDDNS setup and then input your preferred address and click [Check Availability] to check whether the

inputted address has been used. When successful, you can click [Create Shortcut] button to create a shortcut

on your desktop for convenient access.

Figure 9-11. DDNS setup in iWizard

The iDDNS is a free DDNS service provided by Compro. If you are using dynamic IP, you may want to apply for

DDNS (Dynamic Domain Name Server) service to create a hostname that links to the IP address on your home

or oce network. So even if the IP address changes, you can still use an easy-to-remember URL to quickly

access your IP camera anytime, anywhere. After successfully obtaining the iDDNS address, you only need to

log on to http://xxx (your preferred address).iddns.org to access your IP camera on a web browser.

If your local LAN network and router sit behind a rewall, you'll have to set a HTTP port (that the IP camera

willuse)andallowsinboundaccessonthisport.Forexample,ifyousettheHTTPport“2001”foryourIP

camera, your IP camera's address will be "http://xxx (your preferred address).iddns.org:2001".

If you see the orange exclamation mark next to the HTTP or RTSP port eld after performing system diagnosis

with iWizard, it means you have to set up the port forwarding on your router to enables access to the IP

camerafromexternalnetwork(theInternet).Refertothe“RemoteViewingviaInternetExplorer”sectionof

this manual and look for “Port Forwarding“. You may also need to consult the manufacturer of your router for

setting instructions.
