Last article "Setup Internet Connection To Digital Video Recorder Behind Router," we are based on a static IP, we talked about setting up an Internet connection to security DVR. I was lucky anyone reading this article assuming no less (do not worry, you are not alone) was unable to get a static IP connection from Internet service providers. Are depleted rapidly and the IP number just like a phone number, ISP some of this pool of IP addresses, has taken appropriate measures to guarantee will be available for future expansion . Some companies it is the main reason decided to assign a static address to the only commercial accounts. High-speed providers are available only in some cases, the cable company. Cable DSL, which does not provide a static IP at all, it has a higher rate.So, what will we do...
There are several different options there, in this tutorial, I will focus on the free alternatives.Before into the details, let's look at the terms of the DNS. DNS stands for Domain Name System or server, it obtains an IP address as input, Mach, try the domain name has been known before. In our case, we update the IP address in response to changes, to assign an IP address in the specified domain name is going to use a Dynamic Domain Name Service. We have to access the security DVR, than to use the domain name.
Option 1:
Alternatives have been recommended for standalone security DVR is a Linksys WRT54G router that supports DDNS, is to use. Set up a free account go first and use the account information is available by logging into the router, go to the page of the DDNS. Dyndns.com choose the type of account passwords and service providers. After saving the router will send an update to IP dyndns.com account, despite the dynamic IP connection is always forwarded to the current IP.
Option 2:
DVR, if you do not support DDNS own for DVR PC-based surveillance, and go to service providers the same, but you need to set up the account again, in this case, we instead download the updater software Please use it instead of your router to update. During a software update, the update is more reliable than the router, it requires a computer running at all times. Because it runs non-stop during a software update is a more practical reason why a PC-based DVR. Both options are completely free, we can be able to access the surveillance DVR with dynamic IP.
