How to View Your Security Cameras Over The Internet

Security systems have continued to evolve with modern technology, allowing users to record security camera footage to a digital video recorder instead of a simple tape and view the footage via the Internet. It will take a bit of networking knowledge to set up the DVR to be viewable online. You'll need to know your router's external internet protocol address as well as the internal address for your router and the DVR attached to the router.

Step

Connect your security camera DVR to your network router using a Cat-5 network cable. Log in to your router's configuration utility. Type in the local IP address of your router in a Web browser's address bar, for example: "http://192.168.1.1." Check with your router manufacturer for the address of your router. Type in the password for your router and press "Enter."

Step

Access the Local Area Network settings on your router and create a reserved or static IP address on your LAN for your security DVR. This will allow you to set up the DVR to access that specific address and prevent any other devices on the network from being assigned the same address and causing conflicts later. Note the subnet mask number -- typically it's 255.255.255.0.

Step

Forward the ports from your DVR's IP address. The settings vary from router to router, but typically you will add a port forward and specify the IP address. Type in the address you assigned to the DVR. Then set it to forward port 80. Depending on your DVR you may need to forward more than one port. Repeat the process for all the ports required by your DVR. For more information on port forwarding, check portfoward.com.

Step

Power on your DVR and access the network menu system. Enter the setup section for networking and choose a static IP address setting. Enter the IP address that you assigned in the router configuration. Input the subnet mask number. The default gateway is the same as the IP address you used to log into the router and the domain name server is the same as well. Ensure that the ports on the DVR match the ports that you forwarded through the router. Save the settings.

Step

Enter the external IP address of your router into a Web browser from outside your LAN. If you don't know your external IP address you can visit whatismyip.com to tell you. This should prompt you to install the ActiveX control for your DVR's web server. Install the control and then log in to your DVR remotely to view your security cameras over the internet.
