Surveillance System Networking & Internet Setup Resources

LinkSys Router
Whether you are setting up a Geovision system, IP security cameras, or a Stand Alone surveillance DVR, the network and Internet setup is very similar in all cases. Below are generic instructions for configuring different routers to enable port forwarding and dynamic DNS support.

Port Forwarding

Port forwarding, in the context of a networked video surveillance system, is a function of routers/switches that allows a user to configure Internet access and communication to your surveillance DVR, Geovision computer, or IP security camera. Click here for a more detailed explanation of port forwarding.

Port Forwarding Setup

D-Link Port Forwarding (older D-Link Routers) - These instructions illustrate how to setup port forwarding, also known as virtual server, for the D-Link DI-624 wireless router/switch. Most other D-Link products should setup in be the same or similar.

D-Link Port Forwarding for DIR 615 - DIR-825 - DIR-655 - DIR-628 (newer D-Link Routers).

LinkSys Port Forwarding - These instructions illustrate how to configure port forwarding for the LinkSys WRT54G wireless router/switch. Most other LinkSys products should be configured in the same or similar.

2-Wire Port Forwarding - 2-Wire port forwarding is setup by configuring a hosted application in the firewall settings. Click on the preceeding like to follow step by step instructions.

Static DHCP Setup
Setting up a static IP within your DHCP settings of your router allows you to always use the same internal IP address for your DVR. If your router ever restarts or there is a power outage, you do not have to worry about your router assigning a different IP address to your DVR, which renders your port forwarding settings useless.

Dynamic DNS Setup

Dynamic DNS is a free service that provides you with a host name to access your DVR remotely. This service is only necessary if your Internet connection (usually cable or DSL) uses a dynamic IP address. DYnamic IP address means thsat the IP address that your ISP provides you with can change each time that you connect. The opposite is a static IP address which means that each time you connect, your ISP always assigns you the same IP address. Follow these instructions first to setup your free dynamic DNS service.

After your dynamic dns (DDNS) service is setup, follow these instructions to configure your router to keep the service up to date. Your router does this by knowing the hostname, userid, and password of your DDNS account and notifying the service of any changes to your Internet connection's IP address.

Surveillance System Networking Notes

  • When a DSL modem or any model is properly bridged to a router, the WAN IP address should be the same as the Internet public IP address. This can be checked by going to the network status page of most routers.
  • The gateway IP address of your DVR should be the IP address of your router.
