Remote Viewing With Dynamic And Static IP Addresses

Scenario: You have just had your home or business robbed. You decide that next time you will be a little more prepared and hopefully prevent something like this happening again, so you get a security camera system. You want something that is going to do the job with good quality video, a long retention period, and great remote accessibility. What you want is a system with flexible remote viewing options. Not sure of what remote viewing is exactly? Well, it is the ability to view your surveillance system in live time, and it’s prerecorded  footage, via a separate media outlet. Definitely not a bad way to keep track of what is going on at your home or business when you’re not present. Obviously to make this happen, there has to be some type of internet connection to allow the system to be viewed remotely. This requires a good IP address, but there are different types of IP addresses and you are going to need to know the difference to successfully setup any system for  remote viewing.

So now you know it’s remote viewing that you want .. you want it get it set up. First you need to figure out what type of IP address you are working with. Is it static or dynamic? If you are using a static IP address, that means that you Internet Service Provider (ISP) will assign your cable or DSL modem (the box your router connects to) the same IP address every time you were to connect to the internet. If you are going with a dynamic IP address, things get a bit more complicated. Using a dynamic IP address means that your ISP can change your IP address every time that one of your devices connects to the internet. Much like trying to send a letter to a friend while they are  traveling the country, you better have a plan if you expect that to work out.

The next thing you will need is a network- able DVR. This network-able DVR is what is going to allow you to not only control your surveillance system, but also view what your cameras see remotely. As long as you can make a remote connection to the DVR via your internet connection, you’ll be able to pull this off. If you are using a static IP address, just make sure your router points that to your DVR and you will be able to remote view your security camera system at anytime. Using the dynamic IP address makes things slightly more challenging due to the fact that your IP address could be changed at any time by your ISP. The best way to go about remote viewing through a dynamic IP address is by using a dynamic DNS service, or DDNS for short.

By using a DDNS service, you’ll create a host name and associate it with your current IP address given to you from your ISP. Once it is connected to your router, and your router senses a change in your IP address, your router will then send a notification to your DDNS host name telling it what your new IP address is. This way, you only have to remember your host name to connect to your DVR instead of keeping track of all of the changes in IP addresses. Static IP addresses are easier to maintain but not as secure as dynamic IP addresses. In the long run, it may b better to use a dynamic IP address, and just use a free DDNS service. At least this way it will be a bit more secure.
