How to do setup on cctv network

Assuming you use WinXP on your CCTV PC :
1) Install all your DVRNet software on the CCTV PC (Drivers, Apache web server & etc).
Configure your site name & access password.

2) Set the CCTV PC to have a static IP address like 192.168.1.100.
Test the web server by launching IE and enter the IP address or PC name on the browser address bar.
Continue to login and then install the ActiveX viewer in IE once and you should be able to view the CCTV.

3) Configure the router/modem to port forward/allow incoming port 80, 8080 & 8081 to the CCTV PC IP address.

If your broadband package is using static IP, skip steps 4 & 5.

4) If your broadband package is not using static IP, register for DNS service like www.dyndns.org and set a URL like "yingnan.dyndns.org" in the host section of the DynDNS account configuration.

5) Download and install the DynDNS IP updater client on the home PC, & configure it with your DynDNS account IP, password, and host URL you have set above and set it to run automatically as a System Service.

(If your router/firewall support DynDNS service, you don't have to download & install the software, but some routers are not DynDNS compliant & your URL might get banned for repeated updating from same IP address)

6) Use a WinXP PC with Internet connection and run the IE (I don't think it works for Vista) for this because of the ActiveX plugin, Firefox/Opera/etc won't work.

7) Enter the public static IP (if you have) or the DynDNS hostname you have registered -> yingnan.dyndns.org into the IE address bar.

You should be able to see the WebDVR login screen.
Otherwise you can also install the DVRNet client viewer & configure it using the static IP address or DynDNS name if you don't want to use Internet browsers.
